How it works
Two ways to authenticate
Sign in — Claude’s web, desktop, mobile and Cowork clients can’t send a custom header, so they authorize in the browser instead. Cognizo is an official Claude connector, so you add it from the directory and pick which organization it reads. No key is ever created or pasted. API key — everything else, including Claude Code and ChatGPT, sendsX-API-KEY. The organization comes from the key.
Both end up in the same place: one organization’s data, the public surface
only. Connect a client covers each.
What it can reach
Exactly what your credential can reach, and nothing more:- The public API surface — brands, topics, prompts, citations, competitors, ads, regions, opportunities and Content Studio.
- Only brands your organization owns.
403, the same as a
direct API call. The MCP server has no privileges of its own — it is a proxy,
not an account.
The server holds no credentials. Your key or token travels with each
request from your client, is forwarded upstream, and is never persisted. See
Security & troubleshooting.
