mcp-lazy-proxy

MCP Lazy Proxy is a lazy proxy for LLM clients that exposes only two meta-tools, get_mcp_tools and call_mcp_tool, instead of injecting every backend MCP server's tool schemas into the model context. Backend servers are connected lazily, their tool lists are cached, and idle connections are closed automatically. The proxy supports both remote (HTTP/Streamable) and local (stdio subprocess) MCP servers, and can run either as a stdio subprocess spawned by an MCP client or as a self-hosted HTTP server for shared use. It allows marking a backend as a favorite to inject its schemas eagerly while the rest stay lazy, providing a middle ground between all-lazy and all-eager approaches. The proxy also advertises the backend catalog via MCP instructions, so the model knows what's available up front.
