Mintlify Index MCP gives AI agents read-only access to technical documentation and the open web, using a context tool to research implementation questions and return ranked, source-cited context from relevant technical sources.
ChatGPT is OpenAI's assistant. It can add custom MCP servers as plugins, which lets it call your tools from a conversation.
This guide connects Mintlify Index MCP to ChatGPT through MewCP, so ChatGPT can use Mintlify Index MCP's 1 tool, like context.
Mintlify Index MCP needs no credentials, but every call still runs through MewCP: scoped, checked and logged like any other.

Other clients
Mintlify Index MCP works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Mintlify Index MCP tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
In ChatGPT, open Plugins and choose Add custom MCP.
Name it "mewcp" and paste the server URL.
Click Connect. A sign-in window opens; sign in to MewCP and approve access. No API key needed.
Start a new chat and ask: "List the tools you can use from MewCP." You should see your connected apps.
Research an implementation task and return a compact answer with primary-source citations.
