Fetchmcp MCP server

fetchmcp

A drop-in replacement for the official fetch MCP that actually works on modern web pages.

The official fetch MCP is broken on JavaScript-heavy pages, truncates output at 5,000 characters, and ships an unpatched SSRF vulnerability. fetchmcp returns clean, LLM-ready Markdown from any URL — rendering JavaScript when needed, passing basic bot protection without paid proxies, and telling you honestly when a page is blocked instead of hallucinating content. npx and go.

// Replace the official fetch server with this — one line in your MCP config:
"fetchmcp": { "command": "npx", "args": ["-y", "@labtoolsstudio/fetchmcp"] }

 

Why switch

Install

Add to your MCP client config (claudedesktopconfig.json, Cursor mcp.json, Cline, etc.):

{
  "mcpServers": {
    "fetchmcp": {
      "command": "npx",
      "args": ["-y", "@labtoolsstudio/fetchmcp"]
    }
  }
}

The install is light — no browser is downloaded up front, and static reading (fetch → Readability → Markdown) works immediately. The first time a page actually needs JavaScript, fetchmcp downloads a stealth Chromium once (~150 MB) automatically, then renders it — still zero-config. To pre-download it at install time, set FETCHMCPPREINSTALLBROWSER=1. To stay static-only and never download it, set FETCHMCPSKIPBROWSERDOWNLOAD=1 (JS pages then return an honest needsjs).

Tools

read_url

Fetch any web page as clean Markdown.

read_docs

Same engine, tuned for documentation: strips navigation sidebars, headers, and footers so API docs and guides come back as clean reference text. Takes url, render, headers, maxlength, startindex.

Honest statuses

Shortened. The full README is on GitHub.
