Grok + Housecall Pro: No Connector, and the Way In
Grok has no Housecall Pro connector, built in or in its catalog. Your board, your estimates and your invoices sit somewhere Grok has never been. Add Carly to Grok once and Housecall Pro comes with it, in the same chat as your mail and calendar.
Where Housecall Pro sits against Grok’s connector list
Grok’s built-in connectors cover Gmail and Google Calendar, Google Drive, Outlook Mail and Calendar, Microsoft Teams, OneDrive, SharePoint and Salesforce. The catalog xAI publishes beside them adds Box, Canva, Gamma, GitHub, Linear, Meltwater, Notion, S&P Global and Vercel. That is an office stack. Housecall Pro is not on it.
Grok Bot is worth checking separately, because its plugins are a different list kept in a public repository. Sixty-five apps are in there today, and they are the same shape: CRMs, mailboxes, note takers, finance tools. Not one entry is field service software. No Housecall Pro, no Jobber, no ServiceTitan.
So the gap is not one missing connector. The whole trade category is absent. Grok can read the email a property manager just sent about a boiler. It cannot tell you who is closest to that address, what you quoted the same building in March, or whether the last invoice there got paid.
Housecall Pro has not built an MCP server
Grok’s custom connector dialog takes any public MCP server URL, so the real question is whether Housecall Pro publishes one to paste. It does not. Its developer documentation covers REST endpoints and webhooks for customers, jobs, estimates, invoices, materials and lead injection, and the letters MCP do not appear anywhere on the site.
What exists instead is a dozen community projects on GitHub, none affiliated with Housecall Pro. The most complete carries around 95 tools and was written by someone who runs a service company on the product. They are local servers: you install them on a machine, you keep them updated, and they stop when that machine sleeps. Grok’s connector list is a remote list, so a local server is not something you can point it at.
The one remote variant published is a proxy you deploy to your own hosting and then reach at a URL with your API key written into the path. Its own README says to treat that URL like a password, which is fair warning and also the reason most shops should not go that way. Hosted alternatives come from the general integration platforms, Pipedream and Zapier among them, each one more account holding a key to your customer list.
Add Housecall Pro to Grok through Carly
- In Housecall Pro, go to My Apps → All Apps → API Key Management and click Generate API Key. Name it and choose Full access or Read-only. Only an Admin user can generate a key, and API access comes with the MAX plan. Then paste it into Carly on the integrations page.
- In Grok, go to
grok.com/connectors, click New Connector, then choose Custom. - Enter
https://carlyassistant.com/mcp/and complete the sign-in. - Ask Grok about your jobs. The Carly connector answers with live Housecall Pro data.
On Grok Business and Enterprise, a team admin provisions custom connectors in the cloud console before members can add one. In Grok Bot the same server goes in as a plugin: open Plugins from the sidebar, add https://carlyassistant.com/mcp/, and sign in. Your Cursor team’s MCP policy decides whether members can add servers of their own.
What Grok can do with Housecall Pro once Carly is in
- “Josh Lambert’s first call on Ridgeway Drive is running two hours over. Who else is on his board today, and draft what each of them should hear.”
- “Which estimates have been sitting unanswered for more than a week, and what are they worth together?”
- “Pull everything we have done at Claire Whitfield’s address on Sycamore Lane before I price the panel swap.”
- “Which jobs closed out yesterday without a review request going to the customer?”
With Grok’s Gmail or Outlook connector sitting beside the Carly connector, the customer’s email and the job record land in one answer instead of two tabs and a phone call to the office.
Housecall Pro’s AI Team is not a Grok integration
Housecall Pro ships its own AI, and it is genuinely good at the job it was built for. CSR AI answers calls and web chats, reads your live availability, and books work inside your hours with your pricing rules. Analyst AI answers questions about revenue, job trends and tech performance from your own numbers. Coach AI, Marketing AI and Help AI fill out the suite.
All of it runs inside Housecall Pro, on Housecall Pro data. None of it is an MCP server, and none of it reaches your Grok account. CSR AI is the right answer to a missed call at 7pm. It was never built to answer the property manager.
The Housecall Pro work that happens after the chat closes
A connector answers when you ask. Nothing in Grok is watching your board.
Grok was the first big assistant to react to an event rather than a clock, and the event is always an email. Automations fire on a schedule, or on an inbox match by sender, recipient, or subject, with email triggers reserved for SuperGrok. No other app can start one. Carly's triggers reach past the inbox, to a booking arriving, a form coming in, or a record changing in the apps you already use.
Field service does not run on questions, it runs on events, and the events land while you are under a house. A job gets marked complete and the review ask should go out while the tech is still loading the van, not on Friday when someone remembers. An estimate goes quiet on day eight and somebody has to nudge it before it is dead. The morning falls apart and three afternoon customers need to hear about it before they call you first. An invoice hits two weeks unpaid.
Carly is the part that watches for those and starts the work: it reads the job, writes the message, sends it from your mailbox, moves the appointment, and logs what it did. Carly connects to thousands of apps, so the same connector that brings Housecall Pro into Grok also reaches Gmail, Outlook, your calendars and your booking pages, all of them behind one sign-in. You set it up by describing what you want in plain words. Free Zapier-style workflows; AI agents from $35/month. Get started at carlyassistant.com.

What people report going wrong with Grok’s custom connectors
Custom connectors are young, and two public reports are worth reading before you lean on one. A GitHub issue opened on 6 September 2026 against the Unraid MCP plugin walks through a failed attempt to add a server to Grok as a custom connector. Discovery worked, then the sign-in died at Dynamic Client Registration when the server rejected Grok’s callback address. The reporter’s conclusion is that Grok’s dialog only does OAuth with PKCE and dynamic registration, with no way to hand it a fixed token instead. That issue is still open, and it is the reason a key-in-the-URL proxy is not the shortcut it looks like.
Separately, a thread on Cursor’s community forum opened 14 August 2026 describes custom MCP servers in Grok Bot hanging and dragging every other connector down with a deadline error, while staying invisible in the Plugins screen so nobody could remove them. More than twenty people reported the same behaviour before Cursor shipped a fix on 7 September. If a connection stalls, remove it at grok.com/connectors and add it again before blaming the server.
FAQ
Does Grok have a Housecall Pro connector?
No. Housecall Pro is not among Grok’s built-in connectors (Gmail, Google Calendar, Google Drive, Outlook, Teams, OneDrive, SharePoint and Salesforce) and it is not in the catalog. The way in is a custom connector, and Carly’s is https://carlyassistant.com/mcp/.
Is there a Housecall Pro MCP server? Not an official one. Housecall Pro’s developer documentation never mentions MCP. A dozen community servers exist on GitHub, the largest at roughly 95 tools, but they are unaffiliated, they run locally, and you maintain them yourself.
Where do I find my Housecall Pro API key? Under My Apps → All Apps → API Key Management, with Generate API Key. You need to be an Admin user, and you choose Full access or Read-only when you create it.
Can Grok Bot work with Housecall Pro?
Not through a plugin of its own. Grok Bot’s plugin list runs to sixty-five apps and holds no field service software at all. Add Carly as a plugin with https://carlyassistant.com/mcp/ and Grok Bot reaches Housecall Pro through it.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
