MetaMCP MCP Server: Universal Adapter for AI Applications

Overview: What is MetaMCP MCP Server?

MetaMCP MCP Server is a sophisticated proxy server designed to simplify the integration of multiple Model Context Protocol (MCP) servers into a single, cohesive system. By acting as an intermediary, it enhances AI applications such as Claude Desktop, Continue, and Cursor by facilitating seamless communication with various data sources and tools. This server fetches tool configurations from MetaMCP App, enabling users to manage their MCP clients through a unified interface.

🔧 Core Features & MCP Capabilities

Compatibility Matrix

The MetaMCP MCP Server supports a broad range of MCP clients, ensuring that developers can seamlessly integrate it into existing workflows. As shown in the compatibility matrix below, MetaMCP is fully compatible with popular AI applications such as Claude Desktop and Continue but does not support Cursor at present.

MCP Client	Resources	Tools	Prompts	Status
Claude Desktop	✅	✅	✅	Full Support
Continue	✅	✅	✅	Full Support
Cursor	❌	✅	❌	Tools Only

Advanced Configuration & Security

MetaMCP MCP Server allows for fine-grained configuration through environment variables and command-line flags, making it highly flexible. Users can specify an API key directly or set it via the METAMCP_API_KEY environment variable. Additionally, developers can choose between different transport types—either standard input/output (stdio) or server-sent events (SSE)—through the --transport option.

Performance & Compatibility Matrix

MetaMCP MCP Server ensures compatibility with any MCP client and optimizes performance by efficiently routing requests to the correct underlying servers. It supports multiple workspaces, enabling users to switch between different sets of configurations easily. The server also offers dynamic user interfaces for real-time updates of MCP settings.

🚀 Getting Started with Installation

Installing via Smithery

Sometimes, installation via Smithery works as confirmed in Windsurf locally. However, it can also be unstable due to the specificity of MetaMCP. Here's how you can install MetaMCP MCP Server using Smithery:

npx -y @smithery/cli install @metatool-ai/mcp-server-metamcp --client claude

Manual Installation

For those who encounter stability issues, manual installation is recommended:

1. Export your API key:

   export METAMCP_API_KEY=<your api key>
   

2. Start the MetaMCP MCP Server using:

   npx -y @metamcp/mcp-server-metamcp@latest
   

3. Alternatively, for configuring multiple servers in a more structured way:

{
  "mcpServers": {
    "MetaMCP": {
      "command": "npx",
      "args": ["-y", "@metamcp/mcp-server-metamcp@latest"],
      "env": {
        "METAMCP_API_KEY": "<your api key>"
      }
    }
  }
}
