Tool Search Proxy MCP

An MCP server that allows models to search and call tools from a large catalog without loading all definitions. It exposes five tools: search_tools, describe_tool, call_read_tool, call_read_tools, and call_write_tool. This reduces token usage by 97% on 500 tools and validates input schemas before upstream calls.

Package and access
