datolabs-io/mcp-toolsearch-proxy: MCP tool search proxy for large catalogs

mcp-toolsearch-proxy is an MCP server that places search, description, and execution tools in front of large Model Context Protocol tool catalogs to reduce token usage. By dynamically matching queries using BM25 and a multilingual embedding model, it reduces tool definition tokens by 97 percent for a 500-tool catalog while maintaining task success rates comparable to loading every tool directly.
