# MetaMCP
|
||
|
|
|
||
|
|
**MetaMCP** is an MCP proxy that allows you to dynamically aggregate MCP servers into a unified MCP server and apply middleware. MetaMCP itself is also an MCP server, so it can easily connect to **any** MCP client.

|
## Key Features
|
||
|
|
|
||
|
|
- 🏷️ **Group MCP servers into namespaces**, host them as meta-MCP, and assign public endpoints (SSE or Streamable HTTP) with authentication. Switch endpoint namespaces with one click.
|
||
|
|
- 🎯 **Choose only the tools you need when mixing MCP servers**. Apply other pluggable middleware such as observability, security, etc.
|
||
|
|
- 🔍 **Enhanced MCP inspector** that supports saving server configurations and checking if MetaMCP endpoints are available locally.
|
||
|
|
- 🔍 **Elasticsearch for MCP tool selection**.

## Core Concepts
|
||
|
|
|
||
|
|
### MCP Server
|
||
|
|
MCP server configuration that tells MetaMCP how to start an MCP server.
|
||
|
|
|
||
|
|
### MetaMCP Namespace
|
||
|
|
- Group one or more MCP servers into a namespace
|
||
|
|
- Support enabling/disabling MCP servers at server or tool level
|
||
|
|
- Apply middleware to process MCP requests and responses at the namespace level
|
||
|
|
|
||
|
|
### MetaMCP Endpoint
|
||
|
|
- Create endpoints and assign namespaces to them
|
||
|
|
- Multiple MCP servers within a namespace will be aggregated and output as a MetaMCP endpoint
|
||
|
|
- Optional API Key authentication or MCP Spec 2025-06-18 standard OAuth
|
||
|
|
- Exposed via SSE or Streamable HTTP transport protocols and OpenAPI endpoints
|
||
|
|
|
||
|
|
### Middleware
|
||
|
|
- Intercept and transform MCP requests and responses at the namespace level
|
||
|
|
- Built-in example: "Filter inactive tools" - optimize tool context for LLMs
|
||
|
|
|
||
|
|
## Use Cases
|
||
|
|
|
||
|
|
- As infrastructure, hosting dynamically composed MCP servers through a unified endpoint
|
||
|
|
- Choose only the tools you need when mixing MCP servers
|
||
|
|
- Enhanced MCP inspector with support for saving server configurations
|
||
|
|
- Search engine for MCP tool selection
