How does Mercateer work with ChatGPT?

Mercateer runs a public MCP server. You add it as a custom connector in ChatGPT, authorize it once through OAuth, and it can call Mercateer tools to read calls and contacts, quote from your price book, and book appointments, straight from the chat.

Which ChatGPT plans support the Mercateer connector?

Remote MCP connectors are available on the paid ChatGPT plans (Plus, Pro, Business, Enterprise, and Education). Free-tier users can still use Mercateer directly from the dashboard or via Claude Desktop, which is free.

What does ChatGPT need to authenticate?

OAuth handles it. The first time ChatGPT calls a Mercateer tool it opens a consent screen. You sign in, approve access, and the connection is stored, so there are no API keys to paste.

Which Mercateer plan do I need?

API and MCP access is included on the Crew and Fleet plans. You can start building free to set up your agent, then upgrade to connect ChatGPT.

Are there rate limits?

Yes. API requests are rate-limited per caller (about 60 requests per minute per API key or connected agent). If you exceed the limit you get an RFC 9457 problem response with a Retry-After header, so the agent can back off and retry.

Can I give an agent read-only access?

Read-only scoping works through API keys, which each carry an explicit scope list, so you can issue a read-only key for lookups and a separate read-write key for agents that book jobs or update contacts. Note that the OAuth sign-in these agents use grants the agent the same full account access you have in the dashboard, so to keep an agent read-only you would connect it with a scoped API key rather than OAuth. Either way, actions that spend money or change live settings still pause for your confirmation.

What happens to my data?

Your calls, contacts, and pricing stay in your Mercateer organization. Agents act through scoped OAuth tokens or API keys, every request is logged, and actions that spend money or change live settings require your confirmation. Nothing is used to train a shared model.
