How to add MCP servers to ChatGPT
ChatGPT connects to remote MCP servers as custom plugins added from chatgpt.com/plugins. A public server URL, usually ending in /mcp, is the simplest setup.
Add an MCP server to ChatGPT
- 1Open chatgpt.com/plugins, select +, then Add custom MCP server.
- 2Enter a name, then paste the server URL (including
/mcp) under Connection. - 3Set up authentication, accept the warning, and select Create as a plugin.
- 4Only public remote servers over streamable HTTP work; a local server needs a tunnel.
Example: AgentRQ
https://mcp.agentrq.com/mcpRemote servers through plugins
- ChatGPT talks to MCP servers over HTTP at a public URL, usually ending in
/mcp. - A server on your own machine needs a Secure MCP Tunnel; there is no local stdio support.
- Each server becomes a plugin you pick with
@in a conversation. - Workspace admins decide who may add custom servers.
Where ChatGPT keeps MCP servers

Limits and settings
- There is no config file; servers are added in the ChatGPT interface.
- Local servers are reachable only through a Secure MCP Tunnel.
- Account and workspace policies decide who can add custom MCP servers.
- After a server's tools change, use Refresh on the connection.
When a server does not work in ChatGPT
- Test the endpoint first with MCP Inspector (
npx @modelcontextprotocol/inspector@latest). - Check for transport, initialization, schema or authentication errors on the connection screen.
- For tunnels, check the workspace association and the tunnel client's status.
