Source is now in Anthropic's Connectors Directory

October 21, 2026
Source and Anthropic logos: now in Anthropic's Connectors Directory

Source MCP is now listed in Anthropic's Connectors Directory. If your team uses Claude, you can find Source in the directory, sign in, and start asking questions about your attribution data without copying a key or editing a config file.

We launched Source MCP in September so agents could read the same Visit to Pages to Meeting to Deal ledger your dashboard uses. The directory listing makes that connection easier to find for anyone on claude.ai, Claude Desktop, Claude Code, or Claude mobile.

How to connect

In Claude, open Customize > Connectors, search for Source, and choose Connect. You will be sent to Source to sign in and approve access. On Team and Enterprise plans, an Owner adds the connector for the organization first, then each member connects with their own Source account.

Prefer another client? The same server works anywhere that speaks MCP: https://api.source.app/mcp. Use OAuth where the client supports it, or create an API key in Settings > API keys. Each key covers one website, is read-only, and is shown once.

What Claude can do with Source

Once connected, Claude gets five tools:

  • ask: plain-English questions about your attribution data. Returns the answer, the SQL behind it, the result table, and suggested follow-ups.
  • describe_data: your website's tables and columns, with notes on which table answers which question.
  • run_sql: read-only SELECT queries when you want something precise.
  • list_websites: the websites you can query, with the id each tool needs.
  • feedback: flag an answer that looks wrong so we can fix it.

A good first question: "Using Source, what was our cost per conversion by channel over the last 90 days?" Then follow up in the same thread: "Now break that down by campaign, just for paid search."

Your data stays read-only

Claude can query Source. It cannot change or delete anything. Access is scoped to the websites you approve, and you can revoke it any time in Settings > API keys > Connected apps.

New to Source? Create a free account at dash.source.app/signup, add the pixel to your site, and connect Claude. The full setup guide for every client is in our Source MCP launch post.
