Claude + CINC: What the Integration Can (and Can't) Do in 2026
No — there’s no official Claude CINC connector, and CINC hasn’t built one either. CINC (Commissions Inc.) isn’t in Anthropic’s connectors directory, and there’s no ready-made connector for it anywhere. CINC does run a real, modern developer API — leads, notes, deals, communications, and webhooks — but you can’t just grab a key: the credentials are approval-gated, and turning the API into a Claude connection takes a build. Even then, anything you wire up only works inside a chat you start — nothing watches your pipeline or acts while you’re out showing.
Here’s the plain-English version: what’s available, the gate, where it stops, and what to use if you want CINC work to run on its own.
CINC has a genuine API — but you have to be approved to use it
CINC markets an “Open API,” and it’s real: a documented v2 REST API covering leads (full read/write), lead notes and labels, deals, communications history, agents, and webhook subscriptions. That’s a capable, two-way surface — more open than CINC’s closed reputation suggests.
Two things stand between you and a quick Claude hookup:
- Credentials are granted, not self-serve. An individual agent can’t mint API keys from a dashboard. You register an integrator app with CINC (their developer intake runs by email through the CINC/Real Geeks developer team), and a broker then authorizes that app through a sign-in consent flow. Create and update permissions are broker-level, so an individual agent’s access is read-limited by their account permissions.
- A key is not a Claude connection. Once you’re approved, someone technical still has to build and run a small connector (an MCP server — the standard way outside apps plug into Claude) that sits between CINC and Claude.
The lighter route is a real one here: CINC has a strong first-party Zapier integration — triggers for new leads, new inquiries, notes, labels, and pipeline stage changes, plus actions to create and update leads and add notes. Routed through Zapier, Claude could act on those events without anyone building against the raw API.
What a Claude + CINC connection would actually do
Say you got approved (or wired up Zapier) and someone built that connector. What you’d get is a smart assistant inside a chat window: you ask, it answers. You could say “pull this lead’s communication history and draft a follow-up,” and it would. Real value for looking things up and drafting.
What you would not get is anything that runs by itself — and for a team built around fast lead follow-up, that’s the whole point.
The limit that matters: Claude only acts when you ask
Everything Claude does happens inside a conversation you start. Three consequences:
- It never notices anything. There’s no way for Claude to catch that a new lead just registered, or that a lead moved a pipeline stage, and act on it. Nothing happens unless you open a chat and ask.
- Close the chat and it stops. Claude looks up a lead or drafts a note when you ask; it doesn’t sit on your pipeline nurturing prospects. The moment you’re done, it’s done.
- “Scheduled” isn’t really automatic. Claude’s scheduled tasks fire on a fixed clock, not the instant a lead lands, and Claude has no inbox to receive one. That’s not an always-on responder — and CINC’s whole promise is speed to the lead.
What about email — can’t Claude just send the follow-ups? Out of the box, no: Claude’s built-in email (both Gmail and Outlook) only drafts, it doesn’t send — you still hit send yourself. So even “sending” doesn’t get you to hands-off.
Bottom line: Claude with a build is great for “help me pull and write this,” and not built for “respond to every new lead within a minute, day and night.”
CINC’s own AI (“Alex”) is not a Claude integration
Worth separating: CINC ships Alex, a conversational AI lead assistant that auto-texts new leads, qualifies them, and hands off to the agent when they’re appointment-ready — sold as an add-on starting around $200/month. That’s an in-product feature (built with a conversational-AI partner, model undisclosed); it doesn’t connect to your Claude account. “CINC has AI” and “CINC works with Claude” are different claims.
If you want CINC work to happen on its own: Carly
The moment you want something to happen around CINC without you in the chat — text a new lead the instant they register, log the first touch, follow up on a stalled deal — you’ve walked past what Claude is for.
That’s where Carly fits. Where a custom Claude build dead-ends — CINC gates the API credentials behind a manual approval, and any connector you build is laptop-bound — Carly connects to CINC and acts on triggers, always on, no laptop required:
- When a new lead registers, Carly texts and emails them within the minute, then logs the first touch on the lead.
- When a lead moves a pipeline stage, Carly kicks off the right next step — a follow-up, a task, a nudge to you.
- When a lead asks for a showing, Carly checks your calendar, proposes times, and books it.
- Every Monday, your pipeline and stale-lead list roll up into one summary.
Carly drafts and sends across Gmail and Outlook, updates records, and manages tasks. AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. Carly natively integrates with CINC.
Claude vs Carly for CINC
| Claude (with a custom or Zapier build) | Carly | |
|---|---|---|
| Look up leads & communication history | Yes (post-access) | Yes |
| Draft follow-up emails | Yes | Yes |
| Acts on CINC triggers / events | No | Yes |
| Responds to new leads on its own | No | Yes |
| Fires the instant a lead arrives | No | Yes (cloud) |
| Sends the emails itself, not just drafts | No — drafts only | Yes |
| What it takes to set up | Approved API credentials + build, or Zapier | Native integration |
| Pricing | Claude Pro $20 / Max $100–$200, plus the build | AI agents from $35/mo |
Claude with a self-built or Zapier connector is a CINC lookup inside a chat. Carly is a teammate that responds to leads and moves deals forward as things happen.
Frequently Asked Questions
Does Claude work with CINC?
Not officially. There’s no Claude CINC connector and CINC hasn’t built one. You can connect them through a custom build against CINC’s v2 API or through Zapier — but the API credentials are approval-gated (you register an app with CINC and a broker authorizes it), and like anything wired to Claude it only works inside a conversation you start.
Can I get CINC API access on my own?
Not as a self-serve key. You register an integrator app with CINC’s developer team, and a broker authorizes it through a sign-in consent flow. Create and update permissions are broker-level, so an individual agent’s access is limited by their account permissions.
Is Alex a Claude integration?
No. Alex is CINC’s own AI lead assistant for texting and qualifying new leads. It doesn’t connect to your Claude account, and CINC doesn’t disclose the model behind it.
What if I want CINC to act on its own — text new leads, move deals?
That’s outside what Claude does; it responds inside a chat and doesn’t act on events. Carly fires on CINC events and schedules 24/7 in the cloud and can text new leads, log touches, update records, and send pipeline summaries. AI agents start at $35/month.

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."
