MCP Tools

What is MCP Tools?

MCP Tools provides two components for working with the Model Context Protocol: a proxy that forwards stdin data to an HTTP endpoint and returns responses, and a server that loads MCP executables from a directory and exposes their tools to clients via HTTP or stdio with namespaced names.

How to use MCP Tools?

Build all components with make, then run the server (make run-server for HTTP mode, make run-server-stdio for stdio mode). Run the proxy with make run-proxy or directly via ./mcp-proxy -endpoint="https://example.com/mcp". The server scans a directory (default ./mcps) for MCP executables and automatically discovers their tools.

Key features of MCP Tools

• Proxy forwards MCP requests from stdin to a remote HTTP endpoint
• Server loads and manages MCP executables from a directory
• Automatic tool discovery and namespace-based naming (mcpname.toolname)
• Supports both HTTP and stdio transport modes
• Compiled as a single Go executable for easy deployment
• Includes example MCPs (hello-mcp, calculator-mcp) for testing

Use cases of MCP Tools

• Proxy MCP communication from stdin to a remote HTTP server
• Aggregate tools from multiple local MCP executables into one HTTP or stdio server
• Develop and test MCP-compatible tools using the provided examples
• Deploy a lightweight MCP server without requiring a language runtime
