nacos-group/nacos-mcp-router
Nacos MCP Router is an MCP server that acts as a directory and proxy in front of other MCP servers. It builds on Nacos, the dynamic service discovery and configuration platform, and has two working modes. In the default router mode it recommends, distributes, installs and proxies other MCP servers on behalf of the calling assistant. Three tools implement that flow. search_mcp_server takes a task description and keywords and returns candidate MCP servers together with instructions for completing the task. add_mcp_server takes a server name, installs it when it is a stdio server, establishes the connection, and returns the tool list of that server with usage notes. use_tool forwards a call to a named tool on a named target server with a parameter map and returns whatever the target replies, so the client sees one stable entry point instead of many separate server connections. Search is served by pluggable providers. The Nacos provider queries the local Nacos instance with keyword matching and vector similarity search, while the Compass provider calls an external COMPASS API endpoint, by default the mcphub registry, for semantic search with relevance scoring. Environment variables tune the search: COMPASS_API_BASE selects the endpoint, SEARCH_MIN_SIMILARITY sets the minimum score, and SEARCH_RESULT_LIMIT caps the number of results. The second mode, enabled with MODE=proxy, converts SSE and stdio MCP servers into streamable HTTP servers through configuration alone. The router is distributed on PyPI and npm and as a Docker image, and can be launched with uvx, pip, python -m nacos_mcp_router or docker run. Connection to Nacos is configured through NACOS_ADDR, NACOS_USERNAME, NACOS_PASSWORD and NACOS_NAMESPACE, with the password required. Configuration snippets are provided for Cline, Cursor and Claude.
