Alltrails MCP server

AllTrails MCP

A Model Context Protocol server that connects Claude to AllTrails, giving you natural-language access to trail search, trail details, reviews, photos, weather, and your own saved lists and hiking history.

[!WARNING]

AI-developed project. This codebase was entirely built and is actively maintained by Claude. No human has audited the implementation. Review all code and tool permissions before use.

[!CAUTION]

Unofficial and unsupported. AllTrails has no public API. This server reverse-engineers the internal API used by alltrails.com. That API is fronted by DataDome bot protection and governed by AllTrails' Terms of Service. It may break without notice, and automated access may violate their ToS — a prior third-party AllTrails project was disabled at AllTrails' request. Use this only for your own account, at your own discretion.

What you can do

Ask Claude things like:

• "Find waterfall trails near Portland, Oregon"
• "What's the AllTrails rating and length of trail 10236086?"
• "Summarize the recent reviews for this trail"
• "What trails have I marked completed?"
• "Show me the trails on my saved 'weekend hikes' list"

Requirements

• Claude Desktop (or any MCP host)
• Node.js 22.5 or later
• The fetchproxy Transporter browser extension and a signed-in alltrails.com tab (see Authentication)

Acknowledgement of Terms

By using this MCP server, you acknowledge and agree to the following:

1. This server accesses AllTrails using your own signed-in session. It reuses the cookies from your own browser session; it cannot access anyone else's account or private data.

2. AllTrails' Terms of Service govern your use of this server, just as they govern your direct use of AllTrails. AllTrails restricts automated access and scraping, and fronts its API with bot protection. Automated use through this server may breach those terms. You are agreeing to AllTrails' terms every time you invoke a tool.

3. Personal use only. This project is not affiliated with, endorsed by, or sponsored by AllTrails, LLC. It is a personal automation tool. Do not use it to bulk-extract AllTrails' data, to build a competing product, or in any way that burdens their service.

4. You accept full responsibility for any consequences — technical (rate-limiting, CAPTCHA challenges, account action) or otherwise. The maintainer provides no warranty and no support.

This section is the maintainer's good-faith summary — it is not legal advice and does not modify or supersede AllTrails' actual ToS.

Installation

1. Clone and build

git clone https://github.com/chrischall/alltrails-mcp.git
cd alltrails-mcp
npm install
npm run build

2. Add to Claude Desktop

Edit your Claude Desktop config file:

• Mac: ~/Library/Application Support/Claude/claudedesktopconfig.json
• Windows: %APPDATA%\Claude\claudedesktopconfig.json

Add the alltrails entry inside "mcpServers" (create the key if it doesn't exist):

{
  "mcpServers": {
    "alltrails": {
      "command": "node",
      "args": ["/absolute/path/to/alltrails-mcp/dist/index.js"]
    }
  }
}

Replace /absolute/path/to/alltrails-mcp with the path where you cloned the repo.

3. Restart Claude Desktop

Quit completely (Cmd+Q on Mac, not just close the window) and relaunch.

4. Verify
