ATLAS Analysis Facility

MCP Platform

A Model Context Protocolgateway for ATLAS computing — connecting your AI assistant to Rucio, AMI, and the analysis grid, without ever handing it your credentials.

Services

The backend systems your AI assistant can reach through this platform — dataset lookup, metadata, job submission, and more — all exposed as methods it can call directly.

Identities

The external accounts — your CERN/ATLAS login, your grid certificate — this platform uses to act on your behalf, without ever handing your AI assistant a raw credential.

Tokens

A Personal Access Token (PAT) is what lets a client that can't sign in with a browser on its own — like Claude Desktop — connect on your behalf.

Usage

What your AI assistant's tool calls put into its context through this platform — counted as estimated tokens and priced, for scale, at a reference model's input rate. Estimates only: this is not your provider bill.

Connect to this endpoint

Add this server URL to Claude Desktop, Gemini Advanced, or any MCP-compatible client. Your account signs in automatically the first time you connect — you never paste a credential by hand unless your client can't open a browser (see below).

MCP server URL

Claude (Claude.ai, Claude Desktop)

  1. Add a custom connector with just the server URL above — no header, no token needed:Settings → Connectors → Add custom connector.
  2. The first call opens a browser window to sign in with your account. Claude stores the resulting credential itself — you won't see it again.
  3. If your client can't open a browser, skip that step: mint a Personal Access Token (PAT) from the Tokens page instead, then underRequest headers add name Authorization, value Bearer <your PAT>.
