Generate hosted MCP servers from OpenAPI documents with Scalar. Expose API endpoints as AI agent tools, with configurable search and execute modes, built-in OAuth, and secure credential handling.
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 Scalar Docs MCP to ChatGPT through MewCP, so ChatGPT can use Scalar Docs MCP's 1 tool, like search-documentation.
Scalar Docs MCP needs no credentials, but every call still runs through MewCP: scoped, checked and logged like any other.

Other clients
Scalar Docs MCP works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Scalar Docs 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.
Search the available documentation for pages related to a user's query and return a list of related content matching the search criteria.
