MCP Server for Splunk

A Go implementation of the MCP server for Splunk.

Supports STDIO and SSE (Server-Sent Events HTTP API). Uses github.com/mark3labs/mcp-go SDK.

Quickstart - Cursor integration

By configuring MCP Settings in Cursor, you can include remote data directly into the LLM context.

Demo

STDIO mode

bash
cd /tmp # CHANGE ME
git clone https://github.com/jkosik/mcp-server-splunk.git
cd mcp-server-splunk/cmd/mcp-server-splunk/

Update Cursor settings in `~/.cursor/mcp.json`:

json
{
  "mcpServers": {
    "splunk_stdio": {
      "name": "Splunk MCP Server",
      "description": "Splunk MCP server",
      "type": "stdio",
      "command": "/tmp/mcp-server-splunk/cmd/mcp-server-splunk/mcp-server-splunk", # CHANGE ME
      "env": {
        "SPLUNK_URL": "https://changeme.splunkcloud.com:8089", # CHANGE ME
        "SPLUNK_TOKEN": "abcdef" # CHANGE ME
      }
    }
  }
}

Alternatively re-build the server first:

code
go build -o cmd/mcp-server-splunk/mcp-server-splunk cmd/mcp-server-splunk/main.go

SSE mode

Start the server:

bash
export SPLUNK_URL=https://your-splunk-instance:8089
export SPLUNK_TOKEN=your-splunk-token

# Start the server
go run cmd/mcp-server-splunk/main.go -transport sse -port 3001

Update Cursor settings in `~/.cursor/mcp.json`:

json
{
  "mcpServers": {
    "splunk_sse": {
      "name": "Splunk MCP Server (SSE)",
      "description": "MCP server for Splunk integration (SSE mode)",
      "type": "sse",
      "url": "http://localhost:3001/sse"
    }
  }
}

MCP Tools and Prompts

  • `list_splunk_saved_searches`
    • `list_splunk_alerts`
      • `list_splunk_fired_alerts`
        • `list_splunk_indexes`
          • `list_splunk_macros`
            • `internal/splunk/prompt.go` implements an MCP Prompt to find Splunk alerts for a specific keyword (e.g. GitHub or OKTA) and instructs Cursor to utilise multiple MCP tools to review all Splunk alerts, indexes and macros first to provide the best answer.
            • `cmd/mcp/server/main.go` implements MCP Resource in the form of local CSV file with Splunk related content, providing further context to the chat.

            Local usage and testing

            STDIO mode (default)

            bash
            export SPLUNK_URL=https://your-splunk-instance:8089
            export SPLUNK_TOKEN=your-splunk-token
            
            # List available tools
            echo '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' | go run cmd/mcp-server-splunk/main.go | jq
            
            # Call list_splunk_saved_searches tool
            echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"list_splunk_saved_searches","arguments":{}}}' | go run cmd/mcp-server-splunk/main.go | jq

            SSE mode (Server-Sent Events HTTP API)

            bash
            export SPLUNK_URL=https://your-splunk-instance:8089
            export SPLUNK_TOKEN=your-splunk-token
            
            # Start the server
            go run cmd/mcp-server-splunk/main.go -transport sse -port 3001
            
            # Call the server and get Session ID from the output. Do not terminate the session.
            curl http://localhost:3001/sse
            
            # Keep session running and and use different terminal window for the final MCP call
            curl -X POST "http://localhost:3001/message?sessionId=YOUR_SESSION_ID" \
              -H "Content-Type: application/json" \
              -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' | jq
