MCP Server

Use Stockyard as an MCP backend for AI-powered editors and tools.

What is MCP?

The Model Context Protocol (MCP) is an open protocol that lets AI-powered tools connect to external services. Stockyard implements the MCP SSE transport, so any MCP-compatible client — Claude Desktop, Cursor, Windsurf, Cline — can use Stockyard as their LLM backend.

Every request through MCP passes through Stockyard’s full middleware chain: tracing, cost tracking, guardrails, audit logs, caching, and all 76 proxy modules.

Endpoints

Stockyard exposes two MCP endpoints:

GET  /mcp/sse       — SSE connection (client subscribes here)
POST /mcp/message   — Message endpoint (client sends JSON-RPC here)

Available Tools

The MCP server exposes a single chat tool that accepts:

{
  "model": "gpt-4o",
  "messages": [{"role": "user", "content": "Hello"}],
  "temperature": 0.7,
  "max_tokens": 1000
}

The tool routes the request through all configured middleware modules and returns the LLM response.

Claude Desktop

Add this to your claude_desktop_config.json:

Copy{
  "mcpServers": {
    "stockyard": {
      "url": "https://your-stockyard-instance.com/mcp/sse",
      "transport": "sse"
    }
  }
}

Cursor

Create .cursor/mcp.json in your project root:

Copy{
  "mcpServers": {
    "stockyard": {
      "url": "https://your-stockyard-instance.com/mcp/sse",
      "transport": "sse"
    }
  }
}

Windsurf

In Windsurf settings, add the MCP server:

Copy{
  "mcpServers": {
    "stockyard": {
      "serverUrl": "https://your-stockyard-instance.com/mcp/sse"
    }
  }
}
