Bring your own MCP, bring your own business
Grok will take any Model Context Protocol server reachable on the public internet. We did not write a Grok integration - we wrote one standards-compliant MCP server and let every client that speaks the protocol come and get it. No directory to petition, no review queue.
Which suits an owner-operator, because you are not at a desk. You are under a sink or in a van, and the phone is what you have.
"What needs me today?"Late money, unanswered messages, the jobs actually on today.
"Who owes me, and how long?"Oldest first, with amounts, off the ledger.
"Catch me up on the Whitmore job before I knock."Conversation, appointments and invoice in one breath.
"Task: order the flange before Friday."A real task in the real CRM, not a line in a chat you will lose.
How to connect it: five steps
Copy this URL - it is the only thing you need:
https://infioo.ai/api/mcp
- Go to grok.com/connectors and sign in.
- Choose New Connector, then Custom - the right choice, since infioo is not in the built-in list yet.
- Paste the URL as the MCP server URL.
- Complete the sign-in when Grok asks. You choose which business and which permissions, then approve.
- Ask "what needs me today?" If your real brief comes back, you are done.
Grok then reads the tool list off the server itself - nothing to configure tool by tool. No install, no hosting, no tunnel: Grok reaches a custom connector over the public internet rather than from your phone, and infioo.ai is already there. On Business or Enterprise, a team admin provisions the same URL in the cloud console first, then everyone signs in as themselves.
Try it first, with no account
Use this URL at step 3 instead:

No sign-in, no email, nothing to cancel - a fictional plumbing company carrying a normal week's mess. Read-only, and Grok is told the data is invented as soon as it connects.
Eighteen tools. Five write. None send.
Can
- Read contacts, conversations and messages
- Read the schedule, invoices and open tasks
- Search your knowledge base
- Create a task or a contact
- Tag a contact
- Draft a reply for your approval
- Mark an appointment complete
Cannot
- Send a message to a customer
- Create, send or sync an invoice
- Post publicly as your business
- Add anyone to a marketing list
- Touch billing, team invites or payroll
- Manage API keys
- See another business's data
Drafting is not sending. A reply Grok writes becomes a pending draft behind the Approve button already in your inbox. And the right-hand column is not a setting - those tools are absent from the connector, each with its reason recorded in code and a test that fails if one sneaks back. There is a daily write ceiling per business too, so a confused loop cannot run away with your records.
Permissions, and who may grant them
Three permissions - read, write, approve - and your role caps what you may hand over, so plugging in an assistant is never a way to gain access you did not have. Owners and managers may grant all three; staff cannot grant approve; an accountant can grant nothing.
Access tokens last fifteen minutes and refresh tokens rotate. The ceiling is re-applied on every call against live membership, so a change in infioo takes effect in Grok on the next question.
Honest limits
Booking and invoice proposals are not offered from chat yet. Both belong in the owner's approval queue, which today assumes a pending item came from one of your agents - so a proposal from a chat connector would fail the moment you pressed Approve. That code guards real money, so it changes carefully or not at all.
Grok's connector surface is newer than Claude's or ChatGPT's, and xAI moves the UI and the plan lines. The server is built to the published MCP specification rather than to any one client's quirks. If Grok trips on something, that is a bug we want: hello@infioo.com.
