MCP Coordinator: proxy for multiple MCP servers, exposing only 3 tools to Claude (github.com)

The newly announced MCP Coordinator serves as a proxy for multiple MCP servers, significantly enhancing the efficiency of tool utilization within the Claude AI framework. Instead of loading extensive tool definitions from each MCP server—which could consume upwards of 15,000 tokens per interaction—the Coordinator simplifies access by exposing only three essential tools. This innovation reduces the context window usage to approximately 500 tokens, alleviating the burden on Claude’s processing capacity while maintaining full access to the capabilities of various MCP servers. This development is pivotal for the AI/ML community as it streamlines workflows that require interaction with multiple external services without overwhelming the context limits. The Coordinator dynamically loads MCPs as needed, allowing for on-demand access to capabilities like GitHub operations and file management with a simple manifest-based configuration. Moreover, its design requires no API keys for the coordinator itself, only for specific servers that necessitate authentication, thus making it easier for developers to manage server connections efficiently and reduce token bloat. Overall, this enhancement ensures more focused and effective conversations with Claude, streamlining complex workflows in AI applications.
