ChatGPT

ChatGPT supports remote MCP servers via its connectors interface. Configure Overslash as a connector with the URL https://<your-overslash>/mcp, complete the OAuth flow in the popup, and Overslash tools become callable from any ChatGPT conversation that has connectors enabled.

Enable Developer Mode

Full custom MCP connectors live behind Developer Mode:

1. Click your profile → Settings → Connectors.
2. Click Advanced at the bottom.
3. Toggle Developer mode on.

Add Overslash as a connector

1. Back in Settings → Connectors, click Create.
2. Give it a name (e.g. Overslash).
3. Enter the MCP server URL: https://<your-overslash>/mcp.
4. Set Authentication to OAuth.
5. Click Create — ChatGPT opens the OAuth popup.

What the consent screen asks

The popup signs you into Overslash and asks you to pick or create an agent for ChatGPT to act as. Overslash requests a single mcp scope. After you confirm, the connector is bound to that agent's token.

Verifying the connection

Start a conversation with connectors/developer tools enabled and confirm Overslash's tools (overslash_search, overslash_call, …) are listed and callable. Asking ChatGPT to run overslash_auth whoami returns the agent identity it's acting as.

Limits and known issues

ChatGPT connects from OpenAI's cloud

The connector reaches your MCP server over the public internet from OpenAI's side, so the URL must be HTTPS and publicly reachable — http://localhost:3000/mcp will not work.

Plan availability: custom connectors via Developer Mode are available on Plus, Pro, Team, Enterprise, and Edu — not on Free. Developer Mode is beta, so exact labels may shift between releases.
