Quickstart: ChatGPT

This adds Pipeworx as a custom MCP server in ChatGPT. It exposes ~26 meta-tools; the hero tool ask_pipeworx({question}) routes to the full catalog of 3,365 tools across 764 sources at runtime, so you never load thousands of schemas.

① Connect

  1. Settings → Connectors → Advanced → enable Developer mode (requires ChatGPT Pro/Business/Enterprise).
  2. Create → add an MCP server.
  3. Name: Pipeworx
  4. URL: https://pipeworx.io/mcp
  5. Authentication: None.
  6. Save, then enable it in a chat under Developer mode.

Mobile inherits the connector once it’s added.

② Teach it to use Pipeworx

Chat apps expose the tools but don’t inject routing instructions, so the model won’t reach for Pipeworx unless you tell it to. Paste this into Settings → Personalization → Custom instructions:

When I ask for current or factual data — economic stats, SEC/EDGAR filings, stock or crypto prices, weather, FDA drug info, patents, clinical trials, or government records — use the Pipeworx connector (ask_pipeworx) instead of answering from memory or web search. Prefer structured Pipeworx data with citations.

③ Test

In a new chat with Developer mode on, ask:

“Using Pipeworx, what was the US unemployment rate last month?”

ChatGPT should call ask_pipeworx and answer with FRED data plus a pipeworx:// citation. If it answers from memory, you skipped step ②.

Higher limits

Anonymous is 50 calls/day per IP. To raise it:

  • Sign in (200/day): add a connector with URL https://gateway.pipeworx.io/oauth/mcp — the client shows a Connect button; authorize with GitHub.
  • API key (200/day): sign up free at pipeworx.io/signup, get your key at pipeworx.io/account, and use https://pipeworx.io/mcp?apikey=YOUR_KEY.

Tiers: anonymous 50/day · free account 200/day · Paid unlimited.

Troubleshooting

No Developer mode option. It requires ChatGPT Pro/Business/Enterprise; it’s not available on free.

Tools never fire. Confirm Developer mode is toggled on in the chat, and add the Teach rule from step ②.

Connection failed. Re-create the server with Authentication set to None and the URL exactly https://pipeworx.io/mcp.
