--- title: ChatGPT --- # ChatGPT ChatGPT supports remote MCP servers via its connectors interface. Configure Overslash as a connector with the URL `https:///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:///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 ::: warning 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.
