Connecting ChatGPT — current status
ChatGPT cannot connect to CityRadar yet. What the blocker is, what we would have to build, and what to use in the meantime.
Not supported yet
As of August 10, 2026 you cannot connect ChatGPT to CityRadar. There is no setup that works — not a harder one, not an undocumented one. If you use ChatGPT, the practical route today is the CSV export, described below.
Why not
CityRadar’s MCP server authenticates with a single API key, and there are exactly two ways a client can present it: an Authorization header, or the key embedded in the connector URL. Claude Code uses the first; Claude Desktop and claude.ai have no header field, so they use the second.
ChatGPT’s connector flow offers neither. It expects the server to provide an OAuth sign-in — a consent screen the user is redirected to, which hands the client a token — and CityRadar does not have one. That is a gap on our side, not a fault in ChatGPT.
What we would have to build
The OAuth work is specified and understood; it is not started. The shape it would take: a consent page where you paste your CityRadar API key, which then issues a token bound to that key, plus the discovery and registration endpoints a client needs to find it. That approach is deliberate — it means OAuth without user accounts, passwords or a signup flow, none of which exist here yet.
Two other things would improve at the same time: the key would stop travelling inside a URL, and the server would be listable in connector directories that require OAuth.
What decides the timing is whether anyone actually needs it. If you want to use CityRadar from ChatGPT, tell us — a real request is what moves this up the list, and we would rather build it for a named user than on speculation. We will update this page when the status changes rather than announcing it as available beforehand.
What works today
- Export a CSV and give ChatGPT the file. Filter the list you want on the site, export it, and upload the file to a conversation. You lose the live connection, but the data — including contacts and their provenance — is all there. How export works.
- Use Claude for the live connection. Claude Code, Claude Desktop and claude.ai all connect today and are documented step by step in connect Claude.
- The website and the weekly digest need no setup at all.
