Work with ChatGPT
How Crux connects to ChatGPT — status, setup, and how it links to Research and Experience.
Status: Available
Use ChatGPT as an MCP client with the Crux remote HTTPS endpoint — especially to capture research into Crux from the conversation.
Setup
- Open Settings → External sources → AI assistants → ChatGPT (or Settings → Setup MCP → ChatGPT).
- Copy the Crux MCP endpoint URL.
- In ChatGPT (paid plan), enable Developer Mode, then go to Apps / Connectors and create a custom MCP connector.
- Paste the Crux URL, choose OAuth, and complete Crux sign-in when prompted.
- Capture research, ask against your project graphs, or plan work from the chat.
ChatGPT connects to remote HTTPS MCP servers only (not local stdio). Prefer the www host for production.
What ChatGPT can do
The connector exposes the full Crux tool set, so ChatGPT both reads and writes your projects:
- Read — list projects, read the research and experience graphs, ask why an entity exists (
ask_why), and read the current plan (list_plan). - Write — capture research from the conversation (
capture_research), create experience entities, and schedule activities and to-dos (upsert_activity,create_todo).
Writing requires the connection's Write permission, which is on by default. See the full read and write tool list.
ChatGPT only exposes the write tools in Developer Mode connectors; a read-only connector will still answer from your graphs but cannot save anything back.
Plan from the conversation
Ask ChatGPT to plan or sequence work and it reads what is already scheduled, proposes activities, dates, owners, and the to-dos under each, and writes them once you agree. They appear immediately on the Crux Plan calendar and timeline.
How it fits
Crux keeps Research (evidence) and Experience (pages, features, content) linked. ChatGPT plugs into that loop for research capture, asking, and planning — it does not replace the tool you already use for day-to-day work in that product.
Notes
Write scope is on by default for new grants so assistants can save research, schedule work, and register code tags when relevant. Manage grants under Settings → Integrations. For OpenAI’s coding agent, see Work with OpenAI Codex under Build.
