What is the Snf MCP MCP server?

Snf MCP becomes available to MCP clients through the snf mcp mcp server. A Model Context Protocol (MCP) server that provides web search, Wikipedia search, and web content fetching capabilities, written in OCaml using the eio asynchronous runtime.

What Snf MCP does

A Model Context Protocol (MCP) server that provides web search, Wikipedia search, and web content fetching capabilities, written in OCaml using the eio asynchronous runtime.

Key capabilities

  • DuckDuckGo Search — Search the web using DuckDuckGo's search engine
  • Wikipedia Search — Search Wikipedia for articles and content
  • Web Content Fetching — Fetch and parse content from web pages, with support for both cleaned-up HTML and Markdown formats
  • Rate Limiting — Built-in rate limiting to respect service limits
  • MCP Protocol — Fully compatible with the Model Context Protocol specification (vendoring https://tangled.sh/@anil.recoil.org/ocaml-mcp/)
  • Asynchronous — Built on Eio for efficient concurrent operations

Tools it exposes

Once connected, the assistant can call these 5 tools directly:

  • search — The search tool exposed by this server
  • search_wikipedia — The search_wikipedia tool exposed by this server
  • fetch_content — The fetch_content tool exposed by this server
  • fetch_markdown — The fetch_markdown tool exposed by this server
  • LMStudio — Edit the json file from the interface adding the same json entry as in the LLM CLI example above. See also the [official

Installing the snf mcp mcp server

The server is distributed via PyPI as trafilatura, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Where it fits

Search and scraping servers exist to fix the single most common failure of any assistant: answering from stale training data instead of what is on the web today. Snf MCP sits in that group, and the shape of its toolset — search, search_wikipedia, fetch_content among others — tells you what it is really for. Worth comparing against the other search web scraping servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • Maintained by mseri, written in Python.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the snf mcp mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

Frequently asked questions

It connects Snf MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 5 tools (search, search_wikipedia, fetch_content, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Snf MCP directly.
