What is the MCP MCP server?

🔍 Enable AI assistants to search and access medRxiv papers through a simple MCP interface. The mcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 10 defined tools rather than through you.

Adding it to your client

The server ships on npm as @smithery/cli, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Its toolset

Everything the assistant can do here goes through one of these:

  • claude — The claude tool exposed by this server
  • Cursor — Paste the following into Settings → Cursor Settings → MCP → Add new server: - Mac/Linux s npx -y @smithery/cli@latest run
  • Windsurf — The Windsurf tool exposed by this server
  • CLine — The CLine tool exposed by this server
  • search_medrxiv_key_words — The search_medrxiv_key_words tool exposed by this server
  • search_medrxiv_advanced — The search_medrxiv_advanced tool exposed by this server
  • get_medrxiv_metadata — The get_medrxiv_metadata tool exposed by this server
  • download_paper — The download_paper tool exposed by this server
  • read_paper — The read_paper tool exposed by this server
  • list_papers — The list_papers tool exposed by this server

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 10 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch MCP.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the mcp mcp server does with a few real requests.

When to reach for it

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MCP's toolset — claude, Cursor, Windsurf and 7 more — is a fair guide to whether it matches your workflow. It is maintained by JackKuo666; worth a glance at recent repository activity before you build anything load-bearing on it.
