FAQ

MCP server, frequently asked

What is MCP, and why does SourceLoop support it?

Model Context Protocol (MCP) is an open standard, originally developed by Anthropic, for connecting AI agents to live tools and data. Any MCP-compatible agent (Claude, ChatGPT, Cursor, Windsurf, and more) can call into SourceLoop the same way they call any other MCP server. We support it because the moment your team starts using AI agents to think about marketing performance, the agents need real attribution data, not stale screenshots or exports.

Which AI tools does this work with?

Claude Desktop, ChatGPT, Cursor, Windsurf, Zed, Perplexity, and any LangChain or LlamaIndex agent. Custom JSON-RPC clients also work, if it speaks MCP over stdio or SSE, it can query SourceLoop.

What can agents actually query?

The same metrics the dashboard exposes: source, medium, campaign, ad ID, landing page, full conversion path, channel performance, pipeline, revenue, customer-level attribution, and offline-conversion sync status. Same data layer, same filters, no separate API surface to learn.

Is this safe? Can the agent leak data?

Auth is via scoped API keys, one per agent or workspace. You can revoke any key in one click. Every call is logged with the prompt, the resolved query, and the response, so you have a full audit trail. No third-party tokens, no shared credentials.

Can the agent write back to my SourceLoop, my ad platforms, or my CRM?

Yes, with explicit write scopes. Tag a lead, push an offline conversion to Google Ads or Meta, flag a campaign for review, or sync a contact to HubSpot or Salesforce. All write actions are recorded in the audit log and can be disabled per key.

How do I set it up?

Generate an MCP API key from your SourceLoop settings, drop the snippet into your Claude or Cursor MCP config, restart the client. Most teams are live in under five minutes. No SDK install, no scaffolded code.
