D3vTools MCP Server

A Model Context Protocol (MCP) server that provides AI agents with access to 100+ developer utilities — encoders, decoders, color converters, cryptographic tools, formatters, and more. Built for AI coding assistants that need to transform data, inspect formats, or convert between units during development.

The MCP server runs at `https://d3v.tools/mcp/tools` with `streamable-http` transport. No authentication is required.

Tools

This server exposes 3 tools that work together as a discover-execute pipeline:

`list_tools_catalog`

List all available tools with optional filtering by category, tier (free/premium), or slug.

Parameters:

Example:

list tools in the "color" category → list_tools_catalog({ "category": "color" })

`get_tool_details`

Get the full API contract — required fields, input type, rate limits, and keywords — for one tool.

Parameters:

Example:

inspect a tool → get_tool_details({ "category": "encode-decode", "slug": "base64-encode" })

`execute_tool`

Execute a tool with input and optional parameters. Supports text inputs, conversion-style (from/to), and structured options.

Parameters:

Example:

encode text → execute_tool({
  "category": "encode-decode",
  "slug": "base64-encode",
  "input": "Hello, World!"
})

Usage Flow

The tools are designed to be chained:

1. Discover — call `list_tools_catalog` to see available tools

2. Inspect — call `get_tool_details` to learn a tool's API contract

3. Execute — call `execute_tool` to run the tool with your input

Client Configurations

Claude Desktop

Add to your `claude_desktop_config.json`:

{
  "mcpServers": {
    "d3vtools": {
      "url": "https://d3v.tools/mcp/tools",
      "transport": "streamable-http"
    }
  }
}

OpenCode

Add to your `opencode.json`:

{
  "mcpServers": {
    "d3vtools": {
      "url": "https://d3v.tools/mcp/tools",
      "transport": "streamable-http"
    }
  }
}

Cursor

Add in Cursor Settings → MCP Servers:

{
  "mcpServers": {
    "d3vtools": {
      "url": "https://d3v.tools/mcp/tools",
      "transport": "streamable-http"
    }
  }
}

Auto-Discovery

The server is advertised via `.well-known/mcp.json` at `https://d3v.tools/.well-known/mcp.json`, so MCP-aware clients (VS Code extension, etc.) can discover it automatically.

Example Walkthrough

// Step 1: Find available tools
→ list_tools_catalog({ "category": "crypto" })

// Step 2: Get details on a specific tool
→ get_tool_details({ "category": "crypto", "slug": "uuid-generator" })

// Step 3: Execute the tool
→ execute_tool({ "category": "crypto", "slug": "uuid-generator", "input": "" })

The server is built with Laravel and the `laravel/mcp` package. Client-side tools run in-browser JavaScript; server-side tools use PHP service classes. All processing happens on the server or client side — no external API calls.
