Guardian MCP Server

An MCP server that connects an LLM to the archives (since 1999) of The Guardian, including the full text of all articles — more than 1.9 million of them. Useful for real-time headlines, journalism analysis, and historical research.

Installation

A Guardian Open Platform API key is required. You can get one here: https://open-platform.theguardian.com/access/

The Guardian offers generous API access for non-commercial use of the archives, including up to 1 call/second and 500 calls/day. (See the full Terms & Conditions. Commercial use requires a different license.)

To install:

npx guardian-mcp-server

Sample MCP client configuration:

{
  "mcpServers": {
    "guardian": {
      "command": "npx",
      "args": ["guardian-mcp-server"],
      "env": {
        "GUARDIAN_API_KEY": "your-key-here"
      }
    }
  }
}
