Everything

By Anthropic

Not meant for production. Useful if you're building an MCP client and need a server that exercises the full protocol surface.

Install

Run directly:
$ npx -y @modelcontextprotocol/server-everything
Add to claude_desktop_config.json:
{
  "mcpServers": {
    "everything": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-everything"]
    }
  }
}

What you can do with it

  • Test your custom MCP client against a known-good server.
  • Learn the protocol shape by reading the source.
  • Verify that prompts, resources, and tools all work in your harness.
