ChatGPT consumes MCP servers through OpenAI's connectors surface. Deep
research and company knowledge connectors require servers to implement
two read-only tools, search and fetch; developer mode, enabled
under Settings > Security and login, unlocks custom servers with full
tool access, with OpenAI's docs cautioning that "Write actions can
increase both the usefulness and the risks of MCP servers." The same
MCP integration extends beyond the chat client to the Responses API
and the prompts dashboard.
OpenAI's documentation describes the server-sent events streaming interface for connections and recommends OAuth with Client ID Metadata Documents, linking the 2025-11-25 authorization specification. No full MCP spec revision is named for the client, so spec status is recorded as unknown rather than inferred from the authorization reference.
