Quickstart: Mistral Le Chat

This wires Pipeworx into Le Chat as a custom MCP connector, then teaches the model to reach for it. The connector syncs to the Le Chat mobile app too, so you set it up once.

① Connect

  1. Open Le Chat → Settings → Connectors (beta)
  2. Choose add a custom MCP server
  3. Set the URL to https://pipeworx.io/mcp
  4. Save.

Once connected, Le Chat exposes ~26 tools. The hero tool is ask_pipeworx({question}) — it routes your question to the full catalog of 3,365 tools across 764 sources at runtime, so the model never has to load every definition into context. The connector syncs automatically to the Le Chat mobile app.

② Teach it to use Pipeworx

Chat surfaces expose the tools but don’t inject routing instructions, so Le Chat won’t reach for Pipeworx unless you tell it to. Paste this verbatim into an Agent or 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

Start a chat and ask:

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

Le Chat should call ask_pipeworx, which routes to FRED and returns the figure with a pipeworx:// citation. The citation is your confirmation that routing works.

Higher limits

The default URL is the anonymous tier: 50 calls/day per IP, no signup. For more:

  • API key — 200/day: change the server URL to https://pipeworx.io/mcp?apikey=YOUR_KEY. Sign up, then grab your key at pipeworx.io/account.
  • Sign in — 200/day: use https://gateway.pipeworx.io/oauth/mcp instead; the client shows a Connect button — authorize with GitHub.
  • Paid — unlimited: upgrade from your account page.

Tiers at a glance: anonymous 50 · free account 200 · Paid unlimited.

Troubleshooting

Connector won’t add. Connectors are a beta feature — make sure it’s enabled in your Le Chat settings. Re-check the URL is exactly https://pipeworx.io/mcp.

Le Chat answers from memory instead of Pipeworx. The routing rule has to live in an Agent or your custom instructions. Confirm it’s saved and that you’re chatting with that Agent.

Mobile app doesn’t show it. Give the sync a minute; the connector propagates from web. Re-open the app if needed.

Rate-limited. You hit the 50/day anonymous cap. Add ?apikey=YOUR_KEY (from a free account) for 200/day.
