PromptOT for ChatGPT

OpenAI's ChatGPT now works with PromptOT via the Model Context Protocol. Manage prompts, blocks, versions, and test cases without leaving ChatGPT.

Connect via OAuth

Sign in from ChatGPT

ChatGPT desktop and the web app connect via OAuth. Add the PromptOT MCP URL in your custom GPT or workspace settings and sign in with PromptOT.

OAuth flow

No config file. No raw API key. Just sign in.

1. Open ChatGPT settings and add the PromptOT MCP server URL: https://mcp.promptot.com/mcp
2. ChatGPT will redirect you to PromptOT to choose which project to grant access to.
3. Approve the scopes and you're done — ChatGPT can now call the 23 PromptOT tools.

OAuth keeps PromptOT credentials out of your config files entirely.

What you can do

These are some of the most useful day-to-day. See the full catalog on the MCP overview page.

Quickstart

Step 1

Create an MCP-scoped API key from your project's API keys page.

Step 2

Open ChatGPT settings, add the MCP server URL, and approve the OAuth flow.

Step 3

Try “Show me my PromptOT prompts” in ChatGPT. The tools take it from there.

Generate a scoped key, paste the snippet, and ask away. Or browse the other supported assistants.
