Connect CorpusIQ to Grok¶

Grok supports custom MCP connectors, so you can connect it to CorpusIQ and ask questions about your business using live data from your own tools.

One endpoint. 40+ business connectors. No per-source API keys to collect.

What you need¶

A Grok account
A CorpusIQ account with at least one data source connected
About two minutes, one time

Setup¶

Sign in to CorpusIQ and connect the tools you want to ask about (Shopify, QuickBooks, HubSpot, Stripe, GA4, and the rest). This happens on the CorpusIQ side, not in Grok.
Open grok.com/connectors.
Click New Connector, then select Custom.
Enter the CorpusIQ MCP server URL:

https://mcp2.corpusiq.io/mcp

Complete the CorpusIQ sign-in. Grok opens the CorpusIQ authorization page. Approve it once, and the connection persists.
Grok discovers the tools the server exposes. Open a new conversation and ask a question.

The first connection uses OAuth. You approve once in the browser and Grok keeps the token from then on. It takes under a minute.

The server must be reachable over the public internet. The CorpusIQ endpoint is, so no tunneling is needed.

Questions that work well¶

"What was our MRR last month?"
"Which campaign had the best ROAS this quarter?"
"How many orders shipped last week and what was the total value?"
"Show me our top five customers by revenue this year."
"Compare this month's revenue to last month."

Grok calls the CorpusIQ tools, pulls the numbers from your connected sources, and answers with the data cited.

How it is different from the ChatGPT integration¶

	Grok (this guide)	ChatGPT integration
Where	grok.com connectors	ChatGPT app store
How	Custom MCP connector URL	One-click OAuth app
Auth	OAuth, approve once	OAuth, approve once
Best for	Grok users who want live business data in chat	Everyday chat with business data

Both hit the same CorpusIQ endpoint and the same connected data sources.

Troubleshooting¶

Grok says the server failed to connect. Check the URL is exactly https://mcp2.corpusiq.io/mcp with no trailing slash and no extra path.

The authorization page does not open. Approve the connection manually at https://www.corpusiq.io/mcp-auth and retry from Grok.

The tools show up but answers say no data. The CorpusIQ account has no connectors linked yet. Sign in at corpusiq.io and connect at least one source, then ask again.

Answers work, then stop after a while. The access token expired. Re-run the sign-in from the Grok connector settings to refresh it.

Selected tools are missing. CorpusIQ only exposes tools for the sources you have connected. Connect another source in CorpusIQ and the matching tools appear.

What CorpusIQ verifies¶

The endpoint https://mcp2.corpusiq.io/mcp is reachable over the public internet and speaks the streamable HTTP MCP transport.
Its OAuth discovery documents are published at /.well-known/oauth-protected-resource and /.well-known/oauth-authorization-server, with authorization code, refresh, and device grants, PKCE, and dynamic client registration.
A standard MCP client handshake completes against it: session established and the full tool list discovered.

Access to your connected systems stays read-only. CorpusIQ reads from your tools and never changes them. Grok would need separate tools and permissions of its own to take actions on your behalf, and CorpusIQ does not grant them.
