MCP Server

384 MCP tools for your AI editor. One binary. Zero dependencies.

What It Does

stockyard-mcp is a single binary that connects your AI editor to every running Stockyard tool. Feature flags, cron jobs, alerts, caching, cost tracking, guardrails, and 120+ more — all available as native MCP tools in Cursor, Claude Desktop, Windsurf, or Cline.

Ask your editor “What’s my LLM spend this month?” and it calls CostCap. Ask “Create a feature flag called dark-mode at 10% rollout” and it calls SaltLick. The adapter translates MCP tool calls into HTTP API calls to the correct running tool and returns the result.

Install

Copycurl -fsSL https://stockyard.dev/stockyard-mcp/install.sh | sh

Or build from source:

Copygit clone https://github.com/stockyard-dev/Stockyard.git
cd Stockyard && go build -o stockyard-mcp ./cmd/stockyard-mcp/

Usage

# Connect to specific running tools
stockyard-mcp --tools costcap:4100,llmcache:4200

# Auto-discover tools on a port range
stockyard-mcp --scan 4000-7000

# Connect to all tools at default ports
stockyard-mcp --all

# List all 125 known products
stockyard-mcp --list

How It Works

Your AI Editor (Cursor / Claude Desktop / Windsurf / Cline)
    ↓ MCP protocol (JSON-RPC over stdio)
stockyard-mcp (7 MB binary, embedded catalog)
    ↓ HTTP API calls
Running Stockyard tools (costcap:4100, llmcache:4200, ...)

The adapter embeds a catalog of all 125 Stockyard products and their API schemas. When a tool is running, the adapter exposes its endpoints as MCP tools. When the editor calls a tool, the adapter translates the MCP request into an HTTP call to the correct tool instance.

Claude Desktop

Add to claude_desktop_config.json:

Copy{
  "mcpServers": {
    "stockyard": {
      "command": "stockyard-mcp",
      "args": ["--tools", "costcap:4100,llmcache:4200"]
    }
  }
}

Cursor

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

Copy{
  "mcpServers": {
    "stockyard": {
      "command": "stockyard-mcp",
      "args": ["--scan", "4000-7000"]
    }
  }
}

Windsurf

Copy{
  "mcpServers": {
    "stockyard": {
      "command": "stockyard-mcp",
      "args": ["--all"]
    }
  }
}

Cline (VS Code)

Copy{
  "mcpServers": {
    "stockyard": {
      "command": "stockyard-mcp",
      "args": ["--all"]
    }
  }
}

Platform MCP (SSE Transport)

The Stockyard platform also exposes an MCP endpoint via SSE for routing LLM requests through the full middleware chain. This is separate from stockyard-mcp — it proxies LLM completions rather than exposing tool APIs.

GET  /mcp/sse       — SSE connection
POST /mcp/message   — JSON-RPC messages

To use the SSE transport in Claude Desktop:

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