Overview

MetaMCP is a unified middleware MCP server that allows dynamic aggregation of MCP servers into a single MCP server, with the ability to apply middlewares. It can be easily integrated with any MCP clients as it is a MCP server itself. The tool provides features such as namespace grouping, public endpoint hosting with authentication, and pluggable middleware for observability and security. MetaMCP can be used as an enhanced MCP inspector and potentially as an Elasticsearch for MCP tool selection.
