Solution-Based Architecture

The MCP server implements enterprise-grade solution management following Microsoft Dataverse best practices.

Key Benefits

• Professional Schema Naming: Uses publisher-based customization prefixes
• Solution Association: All schema changes are automatically associated with the active solution
• ALM Support: Enables proper solution packaging and deployment across environments
• Persistent Context: Solution context survives server restarts via `.dataverse-mcp` file
• Enterprise Governance: Supports multiple publishers and solutions with proper isolation

Solution Workflow

1. Create Publisher: Define your organization's customization prefix

2. Create Solution: Link solution to publisher for schema organization

3. Set Context: Activate solution for subsequent operations

4. Create Schema: All tables, columns, and option sets use the publisher's prefix automatically

5. Deploy: Export solution for deployment to other environments

Example: XYZ Organization Setup

// 1. Create publisher with "xyz" prefix
await use_mcp_tool("dataverse", "create_dataverse_publisher", {
  friendlyName: "XYZ Test Publisher",
  uniqueName: "xyzpublisher",
  customizationPrefix: "xyz",
  customizationOptionValuePrefix: 20000,
  description: "Publisher for XYZ organization"
});

// 2. Create solution linked to publisher
await use_mcp_tool("dataverse", "create_dataverse_solution", {
  friendlyName: "XYZ Test Solution",
  uniqueName: "xyzsolution",
  publisherUniqueName: "xyzpublisher",
  description: "Main solution for XYZ customizations"
});

// 3. Set solution context (persisted across server restarts)
await use_mcp_tool("dataverse", "set_solution_context", {
  solutionUniqueName: "xyzsolution"
});

// 4. Create schema objects - they automatically use "xyz" prefix
await use_mcp_tool("dataverse", "create_dataverse_table", {
  logicalName: "xyz_project",        // Uses xyz prefix automatically
  displayName: "XYZ Project",
  displayCollectionName: "XYZ Projects"
});

await use_mcp_tool("dataverse", "create_dataverse_column", {
  entityLogicalName: "xyz_project",
  logicalName: "xyz_description",    // Uses xyz prefix automatically
  displayName: "Description",
  columnType: "Memo"
});

Persistent Solution Context

The server automatically persists solution context to a `.dataverse-mcp` file in the project root:

{
  "solutionUniqueName": "xyzsolution",
  "solutionDisplayName": "XYZ Test Solution",
  "publisherUniqueName": "xyzpublisher",
  "publisherDisplayName": "XYZ Test Publisher",
  "customizationPrefix": "xyz",
  "lastUpdated": "2025-07-26T08:27:56.966Z"
}

Benefits of Persistence:

• No Context Loss: Solution context survives server restarts
• Instant Productivity: Developers can immediately continue work
• Consistent Prefixes: No need to remember and re-set solution context
• Team Isolation: Each developer can have their own solution context (file is git-ignored)

• Client Secret: The secret you just created
• Dataverse URL: Your Dataverse environment URL (e.g., `https://yourorg.crm.dynamics.com`)

Installation

1. Install dependencies:

npm install

2. Build the server:

npm run build

3. Copy the full path to the built `index.js` file:

4. Configure the MCP server in your MCP settings file using the copied path (see Configuration section below for details)

Configuration

The server supports flexible environment variable configuration with the following precedence (highest to lowest):

1. MCP environment variables (highest priority)

2. System environment variables

3. `.env` file variables (lowest priority)

Windows MCP Configuration

For Windows users, the MCP configuration requires using `cmd` with the `/c` flag to properly execute the Node.js server:

{
  "mcpServers": {
    "dataverse": {
      "command": "cmd",
      "args": [
        "/c",
        "node",
        "C:\\DEV\\projects\\dataverse-mcp\\build\\index.js"
      ],
      "env": {
        "DATAVERSE_URL": "https://yourorg.crm.dynamics.com",
        "DATAVERSE_CLIENT_ID": "your-client-id",
        "DATAVERSE_CLIENT_SECRET": "your-client-secret",
        "DATAVERSE_TENANT_ID": "your-tenant-id"
      },
      "disabled": false,
      "alwaysAllow": [],
      "disabledTools": [],
      "timeout": 900
    }
  }
}

Important Windows Notes:

• Use `cmd` as the command with `/c` flag
• Use full Windows paths with double backslashes (`\\`) or forward slashes (`/`)
• The `timeout` setting is increased to 900 seconds (15 minutes) for longer operations
• Environment variables can be configured directly in the MCP settings as shown above

⚠️ Security Warning: If you store your MCP settings file in your project directory (rather than in a global MCP configuration location), make sure to add it to your `.gitignore` file to prevent accidentally committing sensitive credentials:

# MCP configuration with sensitive credentials
mcp-settings.json
.mcp-settings.json
mcp.json

Option 1: Using .env file (Recommended for MCP Server Development)

The server automatically loads environment variables from a `.env` file in the project root. This is the recommended approach when contributing to or modifying the MCP server itself.

1. Create your `.env` file:

cp .env.example .env

2. Add the following configuration to your MCP settings file:

{
  "mcpServers": {
    "dataverse": {
      "command": "node",
      "args": ["/path/to/dataverse-mcp/build/index.js"],
      "disabled": false,
      "alwaysAllow": [],
      "disabledTools": [],
      "timeout": 900
    }
  }
}

Note: The `timeout` setting is increased to 900 seconds (15 minutes) to accommodate longer-running operations like schema export, which may need to process large amounts of metadata.

Option 2: Using MCP environment variables (Recommended for Normal Usage)

You can configure environment variables directly in the MCP settings. This is the recommended approach for normal usage when using the MCP Dataverse tool for development activities. These will override any values in the `.env` file:

{
  "mcpServers": {
    "dataverse": {
      "command": "node",
      "args": ["/path/to/dataverse-mcp/build/index.js"],
      "env": {
        "DATAVERSE_URL": "https://yourorg.crm.dynamics.com",
        "DATAVERSE_CLIENT_ID": "your-client-id",
        "DATAVERSE_CLIENT_SECRET": "your-client-secret",
        "DATAVERSE_TENANT_ID": "your-tenant-id"
      },
      "disabled": false,
      "alwaysAllow": [],
      "disabledTools": [],
      "timeout": 900
    }
  }
}

⚠️ Security Warning: If you store your MCP settings file in your project directory (rather than in a global MCP configuration location), make sure to add it to your `.gitignore` file to prevent accidentally committing sensitive credentials:

# MCP configuration with sensitive credentials
mcp-settings.json
.mcp-settings.json
mcp.json

Option 3: Hybrid Configuration

You can also use a combination approach where common settings are in `.env` and sensitive or environment-specific settings are overridden via MCP:

.env file:

DATAVERSE_URL=https://dev-org.crm.dynamics.com
DATAVERSE_TENANT_ID=common-tenant-id

MCP settings (overrides for production):

{
  "mcpServers": {
    "dataverse": {
      "command": "node",
      "args": ["/path/to/dataverse-mcp/build/index.js"],
      "env": {
        "DATAVERSE_URL": "https://prod-org.crm.dynamics.com",
        "DATAVERSE_CLIENT_ID": "prod-client-id",
        "DATAVERSE_CLIENT_SECRET": "prod-client-secret"
      },
      "disabled": false,
      "alwaysAllow": [],
      "disabledTools": [],
      "timeout": 900
    }
  }
}

Usage Examples

Creating a Custom Table

// Create a new custom table with automatic naming
// The system automatically generates:
// - Logical Name: xyz_project (using customization prefix from solution context)
// - Schema Name: xyz_Project (prefix lowercase, original case preserved, spaces removed)
// - Display Collection Name: Projects (auto-pluralized)
// - Primary Name Attribute: xyz_project_name
await use_mcp_tool("dataverse", "create_dataverse_table", {
  displayName: "Project",
  description: "Custom table for managing projects",
  ownershipType: "UserOwned",
  hasActivities: true,
  hasNotes: true
});

// Example with minimal parameters (most common usage)
await use_mcp_tool("dataverse", "create_dataverse_table", {
  displayName: "Customer Feedback"
});
// This creates:
// - Logical Name: xyz_customerfeedback
// - Schema Name: xyz_CustomerFeedback (prefix lowercase, original case preserved)
// - Display Collection Name: Customer Feedbacks
// - Primary Name Attribute: xyz_customerfeedback_name

Important: Before creating tables, ensure you have set a solution context using `set_solution_context` to provide the customization prefix. The system automatically uses the prefix from the active solution's publisher.

Adding Columns to a Table

// String column with email format and automatic naming
// The system automatically generates:
// - Logical Name: xyz_contactemail (prefix + lowercase, no spaces)
// - Schema Name: xyz_ContactEmail (prefix lowercase, original case preserved)
await use_mcp_tool("dataverse", "create_dataverse_column", {
  entityLogicalName: "xyz_project",
  displayName: "Contact Email",
  columnType: "String",
  format: "Email",
  maxLength: 100,
  requiredLevel: "ApplicationRequired"
});

// Integer column with constraints (generates xyz_priorityscore)
await use_mcp_tool("dataverse", "create_dataverse_column", {
  entityLogicalName: "xyz_project",
  displayName: "Priority Score",
  columnType: "Integer",
  minValue: 1,
  maxValue: 10,
  defaultValue: 5
});

// Boolean column with custom labels (generates xyz_isactive)
await use_mcp_tool("dataverse", "create_dataverse_column", {
  entityLogicalName: "xyz_project",
  displayName: "Is Active",
  columnType: "Boolean",
  trueOptionLabel: "Active",
  falseOptionLabel: "Inactive",
  defaultValue: true
});

// DateTime column (date only) (generates xyz_startdate)
await use_mcp_tool("dataverse", "create_dataverse_column", {
  entityLogicalName: "xyz_project",
  displayName: "Start Date",
  columnType: "DateTime",
  dateTimeFormat: "DateOnly",
  requiredLevel: "ApplicationRequired"
});

// DateTime column (date and time) (generates xyz_lastmodified)
await use_mcp_tool("dataverse", "create_dataverse_column", {
  entityLogicalName: "xyz_project",
  displayName: "Last Modified",
  columnType: "DateTime",
  dateTimeFormat: "DateAndTime"
});

// Picklist column with local options (generates xyz_status)
await use_mcp_tool("dataverse", "create_dataverse_column", {
  entityLogicalName: "xyz_project",
  displayName: "Status",
  columnType: "Picklist",
  options: [
    { value: 1, label: "Planning" },
    { value: 2, label: "In Progress" },
    { value: 3, label: "On Hold" },
    { value: 4, label: "Completed" }
  ]
});

// Picklist column using global option set (generates xyz_projectcolor)
await use_mcp_tool("dataverse", "create_dataverse_column", {
  entityLogicalName: "xyz_project",
  displayName: "Project Color",
  columnType: "Picklist",
  optionSetName: "xyz_colors"
});

// Lookup column (generates xyz_account)
await use_mcp_tool("dataverse", "create_dataverse_column", {
  entityLogicalName: "xyz_project",
  displayName: "Account",
  columnType: "Lookup",
  targetEntity: "account"
});

// Memo column for long text (generates xyz_description)
await use_mcp_tool("dataverse", "create_dataverse_column", {
  entityLogicalName: "xyz_project",
  displayName: "Description",
  columnType: "Memo",
  maxLength: 2000,
  requiredLevel: "Recommended"
});

Creating AutoNumber Columns

AutoNumber columns automatically generate unique alphanumeric strings using customizable format patterns. They're perfect for creating serial numbers, reference codes, and other automatically generated identifiers.

// Create an AutoNumber column with sequential numbering
await use_mcp_tool("dataverse", "create_autonumber_column", {
  entityLogicalName: "xyz_project",
  displayName: "Project Number",
  autoNumberFormat: "PRJ-{SEQNUM:5}",
  maxLength: 20,
  requiredLevel: "SystemRequired"
});
// Generates: PRJ-00001, PRJ-00002, PRJ-00003, etc.

// Create an AutoNumber column with date and random string
await use_mcp_tool("dataverse", "create_autonumber_column", {
  entityLogicalName: "xyz_invoice",
  displayName: "Invoice Reference",
  autoNumberFormat: "INV-{DATETIMEUTC:yyyyMMdd}-{RANDSTRING:4}",
  maxLength: 30,
  description: "Auto-generated invoice reference number"
});
// Generates: INV-20250814-A7K9, INV-20250814-M3X2, etc.

// Create a complex AutoNumber format with multiple placeholders
await use_mcp_tool("dataverse", "create_autonumber_column", {
  entityLogicalName: "xyz_order",
  displayName: "Order Code",
  autoNumberFormat: "ORD-{DATETIMEUTC:yyyy}-{SEQNUM:4}-{RANDSTRING:2}",
  maxLength: 25,
  requiredLevel: "ApplicationRequired"
});
// Generates: ORD-2025-0001-AB, ORD-2025-0002-XY, etc.

// Update an existing AutoNumber format
await use_mcp_tool("dataverse", "update_autonumber_format", {
  entityLogicalName: "xyz_project",
  columnLogicalName: "xyz_projectnumber",
  autoNumberFormat: "PROJECT-{DATETIMEUTC:yyyy}-{SEQNUM:6}",
  displayName: "Updated Project Number"
});

// Set the seed value for sequential numbering (starts next sequence from 10000)
await use_mcp_tool("dataverse", "set_autonumber_seed", {
  entityLogicalName: "xyz_project",
  columnLogicalName: "xyz_projectnumber",
  seedValue: 10000
});

// Convert an existing text column to AutoNumber
await use_mcp_tool("dataverse", "convert_to_autonumber", {
  entityLogicalName: "xyz_customer",
  columnLogicalName: "xyz_customercode",
  autoNumberFormat: "CUST-{SEQNUM:5}",
  maxLength: 15
});

// Get AutoNumber column information
await use_mcp_tool("dataverse", "get_autonumber_column", {
  entityLogicalName: "xyz_project",
  columnLogicalName: "xyz_projectnumber"
});

// List all AutoNumber columns in a table
await use_mcp_tool("dataverse", "list_autonumber_columns", {
  entityLogicalName: "xyz_project",
  customOnly: true
});

// List all AutoNumber columns across all tables
await use_mcp_tool("dataverse", "list_autonumber_columns", {
  customOnly: true,
  includeManaged: false
});

AutoNumber Format Placeholders

AutoNumber columns support the following format placeholders:

AutoNumber Format Examples

// Simple sequential numbering
"TICKET-{SEQNUM:5}"
// Output: TICKET-00001, TICKET-00002, TICKET-00003

// Date-based with sequence
"INV-{DATETIMEUTC:yyyyMM}-{SEQNUM:4}"
// Output: INV-202508-0001, INV-202508-0002

// Complex format with all placeholders
"REF-{DATETIMEUTC:yyyy}-{SEQNUM:3}-{RANDSTRING:2}"
// Output: REF-2025-001-AB, REF-2025-002-XY

// Year and random string only
"PROJ-{DATETIMEUTC:yy}{RANDSTRING:4}"
// Output: PROJ-25A7K9, PROJ-25M3X2

// Daily sequence reset pattern
"DAILY-{DATETIMEUTC:yyyyMMdd}-{SEQNUM:3}"
// Output: DAILY-20250814-001, DAILY-20250814-002

Creating Tables with AutoNumber Primary Names

You can create tables with AutoNumber primary name columns directly:

// Create a table with AutoNumber primary name
await use_mcp_tool("dataverse", "create_dataverse_table", {
  displayName: "Support Ticket",
  description: "Customer support tickets with auto-generated ticket numbers",
  primaryNameAutoNumberFormat: "TICKET-{DATETIMEUTC:yyyyMM}-{SEQNUM:4}",
  hasActivities: true,
  hasNotes: true
});
// Creates table with primary name column that generates: TICKET-202508-0001, TICKET-202508-0002, etc.

// Create a project table with year-based numbering
await use_mcp_tool("dataverse", "create_dataverse_table", {
  displayName: "Project",
  description: "Projects with auto-generated project codes",
  primaryNameAutoNumberFormat: "PRJ-{DATETIMEUTC:yyyy}-{SEQNUM:5}",
  ownershipType: "UserOwned"
});
// Creates: PRJ-2025-00001, PRJ-2025-00002, etc.

AutoNumber Best Practices

Format Design:

• Keep formats concise but descriptive
• Use consistent prefixes across related entities
• Consider date formats for time-based organization
• Plan for sufficient sequence digits to avoid overflow

Seed Management:

• Set seed values in development to avoid conflicts
• Remember that seeds are environment-specific
• Use higher seed values in production (e.g., 10000+)
• Document seed values for environment promotion

Column Configuration:

• Set appropriate maxLength to accommodate format expansion
• Use SystemRequired for critical identifier columns
• Consider audit requirements for tracking changes
• Test format patterns before production deployment

Environment Considerations:

• Seed values don't transfer with solutions
• Test AutoNumber generation in target environments
• Plan for data migration scenarios
• Consider backup and restore implications

Mermaid Diagram Generation

The Mermaid Diagram Generation tool converts exported JSON schemas into professional Entity Relationship Diagrams using Mermaid syntax. This provides visual documentation of your Dataverse schema with relationships, column details, and professional formatting.

Key Features

• Professional ERD Generation: Creates publication-ready Entity Relationship Diagrams
• Schema-Based Relationships: Uses only exported relationship metadata for accurate representation
• Enhanced Column Markers: Visual indicators for Primary Keys (PK), Foreign Keys (FK), Primary Names (PN), and required fields
• Lookup Target Display: Shows which tables each lookup column references (e.g., "Lookup (contact, account)")
• Table Filtering: Filter diagrams to specific tables using `tableNameFilter` parameter
• Comprehensive Headers: Generated files include complete context and regeneration instructions
• Mermaid Compatibility: Works with Mermaid Live Editor, VS Code extensions, GitHub, and documentation tools

Usage Examples

// Generate a complete diagram from exported schema
await use_mcp_tool("dataverse", "generate_mermaid_diagram", {
  schemaPath: "my-solution-schema.json",
  outputPath: "schema-diagram.mmd",
  includeColumns: true,
  includeRelationships: true
});

// Generate diagram without column details for overview
await use_mcp_tool("dataverse", "generate_mermaid_diagram", {
  schemaPath: "complete-schema.json",
  outputPath: "overview-diagram.mmd",
  includeColumns: false,
  includeRelationships: true
});

// Generate diagram for specific tables only
await use_mcp_tool("dataverse", "generate_mermaid_diagram", {
  schemaPath: "large-schema.json",
  outputPath: "filtered-diagram.mmd",
  tableNameFilter: ["its_customer", "its_bill", "its_payment"],
  includeColumns: true,
  includeRelationships: true
});

// Generate relationship-only diagram for architecture overview
await use_mcp_tool("dataverse", "generate_mermaid_diagram", {
  schemaPath: "schema-export.json",
  outputPath: "relationships-only.mmd",
  includeColumns: false,
  includeRelationships: true,
  tableNameFilter: ["contact", "account", "opportunity"]
});

Example Output

The tool generates professional Mermaid ERD syntax like this:

erDiagram
    its_customer {
        uuid its_customerid PK "NOT NULL"
        string its_customername "Primary Name NOT NULL"
        string its_email "NOT NULL"
        string its_phone
        boolean its_isactive "NOT NULL"
    }
    
    its_bill {
        uuid its_billid PK "NOT NULL"
        string its_billnumber "Primary Name NOT NULL"
        uuid its_customerid FK "Lookup (its_customer) NOT NULL"
        decimal its_amount "NOT NULL"
        datetime its_duedate "NOT NULL"
        int its_status "NOT NULL"
    }
    
    its_customer ||--o{ its_bill : "Customer Bills"

Column Markers Explained

• PK: Primary Key columns (unique identifiers)
• FK: Foreign Key columns (lookup references)
• Primary Name: The display name column for records
• NOT NULL: Required fields
• Lookup (table1, table2): Shows which tables the lookup column can reference

Diagram Features

• Table Visualization: Each table shows its logical name and all columns
• Column Details: Data types, constraints, and special markers
• Relationship Lines: Visual connections between related tables
• Cardinality Indicators: Shows one-to-many (||--o{) and many-to-many (}o--o{) relationships
• Professional Formatting: Clean, readable diagrams suitable for documentation

Integration with Documentation Tools

Generated Mermaid diagrams work seamlessly with:

• Mermaid Live Editor (https://mermaid.live) - Online diagram editor and viewer
• VS Code Mermaid Preview - Real-time diagram preview in your editor
• GitHub/GitLab - Native Mermaid support in markdown files
• Documentation Sites - Gitiles, MkDocs, and other documentation platforms
• Confluence - Via Mermaid plugins for enterprise documentation

Workflow Example

1. Export Schema: Use `export_solution_schema` to create JSON schema file

2. Generate Diagram: Use `generate_mermaid_diagram` to create visual ERD

3. Review Relationships: Verify all lookup columns show correct target tables

4. Documentation: Include diagrams in project documentation or wiki

5. Team Sharing: Share visual schema with stakeholders and developers

This tool is essential for documenting complex Dataverse schemas and communicating data relationships to both technical and non-technical stakeholders.

WebAPI Call Generator

The WebAPI Call Generator tool helps developers construct proper Dataverse WebAPI calls by generating complete HTTP requests with correct URLs, headers, and request bodies. This is particularly useful for:

• Learning WebAPI syntax - See how different operations translate to HTTP calls
• Debugging API issues - Generate reference calls to compare against your implementation
• Documentation - Create examples for team members or API documentation
• Testing - Get ready-to-use cURL commands and JavaScript fetch examples

// Generate a simple retrieve operation
await use_mcp_tool("dataverse", "generate_webapi_call", {

PowerPages Code Site Integration

This tool is designed to work with PowerPages Code Sites that follow the standard directory structure:

your-powerpages-project/
├── .powerpages-site/
│   ├── sitesetting.yml          # WebAPI and other site settings
│   ├── webrole.yml             # Web role definitions
│   └── table-permissions/      # Individual permission files
│       ├── cr7ae_creditcardses_authenticated_users.yml
│       └── contact_anonymous_users.yml
├── src/                        # Your React components
└── package.json

Example Workflow

1. Check Current Status:

{"operation": "status"}

2. Enable WebAPI for Your Custom Table:

{
     "operation": "configure-webapi",
     "tableName": "cr7ae_creditcardses",
     "fields": ["cr7ae_name", "cr7ae_type", "cr7ae_limit"],
     "enabled": true
   }

3. Create Table Permissions:

{
     "operation": "create-table-permission",
     "tableName": "cr7ae_creditcardses",
     "webRoleName": "Authenticated Users",
     "permissions": {
       "read": true,
       "create": true,
       "write": true,
       "delete": false
     },
     "scope": "Global"
   }

4. Verify Configuration:

{"operation": "list-configurations"}

5. Use with PowerPages WebAPI Generator:

{
     "operation": "retrieveMultiple",
     "logicalEntityName": "cr7ae_creditcardses",
     "select": ["cr7ae_name", "cr7ae_type", "cr7ae_limit"]
   }

This workflow ensures your PowerPages Code Site is properly configured to handle WebAPI calls for your custom tables with appropriate security permissions.

Authentication

The server uses Client Credentials flow (Server-to-Server authentication) with Azure AD. This provides:

• Secure authentication without user interaction
• Application-level permissions
• Suitable for automated scenarios
• Token refresh handling

Error Handling

The server includes comprehensive error handling:

• Authentication errors - Invalid credentials or expired tokens
• API errors - Dataverse-specific error messages with codes
• Validation errors - Parameter validation and type checking
• Network errors - Connection and timeout handling

Security Considerations

1. Store secrets securely - Never commit client secrets to version control

2. Use environment variables - Configure secrets through environment variables

3. Principle of least privilege - Grant only necessary permissions

4. Monitor usage - Track API calls and authentication attempts

5. Rotate secrets regularly - Update client secrets periodically

Troubleshooting

Common Issues

1. Authentication Failed

2. Permission Denied

3. Entity Not Found

4. Invalid Column Type

Debug Mode

Set environment variable `DEBUG=true` for verbose logging:

DEBUG=true node build/index.js

Solution Management Best Practices

Publisher Configuration

When creating publishers, follow these guidelines:

• Unique Prefixes: Use 2-8 character prefixes that identify your organization
• Option Value Ranges: Use non-overlapping ranges (e.g., 10000-19999 for one publisher, 20000-29999 for another)
• Descriptive Names: Use clear, professional names for publishers and solutions

Solution Context Management

// Check current context
await use_mcp_tool("dataverse", "get_solution_context", {});

// Switch to different solution
await use_mcp_tool("dataverse", "set_solution_context", {
  solutionUniqueName: "anothersolution"
});

// Clear context (removes persistence file)
await use_mcp_tool("dataverse", "clear_solution_context", {});

Environment Promotion

1. Development: Create and test schema changes in dev environment with solution context

2. Export: Use Power Platform CLI or admin center to export solution

3. Import: Deploy solution to test/production environments

4. Validation: Verify all customizations use proper prefixes

Git Integration

The `.dataverse-mcp` file is automatically excluded from version control:

# MCP Dataverse context file
.dataverse-mcp

This allows each developer to maintain their own solution context while preventing accidental sharing of environment-specific settings.

Developer Notebook

MCP Configuration Recommendations

This section provides real-world recommendations for configuring the Dataverse MCP server to accelerate development workflows.

Read-Only Tools for `alwaysAllow` Configuration

For faster development cycles, consider adding these read-only tools to your MCP server's `alwaysAllow` configuration. Since these tools only read data and don't make any changes to your Dataverse environment, they're safe to auto-approve and won't cause any side effects.

Recommended `alwaysAllow` configuration:

{
  "mcpServers": {
    "dataverse": {
      "command": "cmd",
      "args": ["/c", "node", "C:\\path\\to\\dataverse-mcp\\build\\index.js"],
      "env": {
        "DATAVERSE_URL": "https://yourorg.crm.dynamics.com",
        "DATAVERSE_CLIENT_ID": "your-client-id",
        "DATAVERSE_CLIENT_SECRET": "your-client-secret",
        "DATAVERSE_TENANT_ID": "your-tenant-id"

Common Development Workflows

Schema Exploration:

// These will execute immediately without approval prompts
await use_mcp_tool("dataverse", "list_dataverse_tables", { customOnly: true });
await use_mcp_tool("dataverse", "get_dataverse_table", { logicalName: "xyz_project" });
await use_mcp_tool("dataverse", "list_dataverse_columns", { entityLogicalName: "xyz_project" });

Solution Analysis:

// Instant solution context and publisher information
await use_mcp_tool("dataverse", "get_solution_context", {});
await use_mcp_tool("dataverse", "list_dataverse_solutions", { includeManaged: false });
await use_mcp_tool("dataverse", "get_dataverse_publisher", { uniqueName: "xyzpublisher" });

Documentation Generation:

// Generate schema documentation without approval delays
await use_mcp_tool("dataverse", "export_solution_schema", {
  outputPath: "current-schema.json"
});
await use_mcp_tool("dataverse", "generate_mermaid_diagram", {
  schemaPath: "current-schema.json",
  outputPath: "schema-diagram.mmd"
});

WebAPI Code Generation:

// Generate API calls instantly for development
await use_mcp_tool("dataverse", "generate_webapi_call", {
  operation: "retrieveMultiple",
  entitySetName: "xyz_projects",
  select: ["xyz_name", "xyz_status"]
});

Developer Security Considerations

While these tools are read-only and safe, consider these security practices:

• Environment Separation: Use different MCP configurations for dev/test/prod environments
• Credential Management: Store sensitive credentials in secure environment variables
• Access Monitoring: Regularly review which tools are in `alwaysAllow` lists
• Team Guidelines: Establish team standards for MCP configuration management

Advanced Configuration Tips

Selective Tool Enabling:

If you prefer more granular control, start with the most commonly used read-only tools:

"alwaysAllow": [
  "get_dataverse_table",
  "list_dataverse_tables",
  "get_dataverse_column",
  "list_dataverse_columns",
  "get_solution_context",
  "export_solution_schema"
]

This configuration approach significantly improves the developer experience while maintaining security through the separation of read-only and write operations.
