The Everything MCP server is the official reference and test server, exercising prompts, resources, and tools so you can validate an MCP client or learn the protocol end to end.
Key Features
- Demonstrates prompts, resources, and tools
- A reference implementation of the protocol
- Useful for testing client integrations
- Great starting point for learning MCP
Use Cases
- Verify a new MCP client works
- Learn how MCP primitives fit together
- Smoke-test a setup before adding real servers
Getting started
Add Everything MCP to your MCP-capable client — Claude Code, Cursor, Codex, and others — by following the setup in the official repository. Most servers register under your client's mcpServers config with a command, arguments, and any required API keys; Everything MCP documents the exact command and credentials in its README.
