Claude + Hunter: What the Integration Can (and Can't) Do in 2026
Yes — Hunter has an MCP server for Claude. Hunter (the email finder and verifier) ships an official MCP server plus a Claude plugin, and you can also connect it through Composio or Zapier. It isn’t a one-click connector in Anthropic’s directory — you add it as a custom MCP server — but the server itself is built by Hunter. Once it’s wired up, Claude can find and verify email addresses inside a chat — domain search, email finder, verification, company enrichment. The catch is the one that applies to every Claude MCP setup: it only works inside a chat you start. There are no triggers, nothing monitors your lists for you, and nothing happens while you’re away.
Here’s exactly what the integration does, how to turn it on, where the limits bite, and what to use if you want Hunter work that runs on its own.
What the Hunter MCP server does
Hunter’s MCP server connects Claude directly to your Hunter account, exposing its lead-generation and enrichment tools so you drive prospecting with natural language.
In practice, the Hunter MCP server lets Claude:
- Find emails — pull the public email addresses for a given company or domain, with metadata.
- Verify addresses — check whether an email is valid and deliverable before you send.
- Search by domain — chain company enrichment → domain search → email finder → email verifier automatically.
- Enrich and organize — pull company data and manage leads and lead lists.
The everyday wins are obvious: “find the emails at this company,” “verify this list before I send,” “who’s the head of marketing here and what’s their email.” All without leaving Claude.
How to set it up
Setup is a custom MCP server, with a few paths depending on how you use Claude:
- Grab your Hunter API key from your Hunter account.
- Add Hunter’s official MCP server as a custom connector (via the Hunter plugin), or connect through Composio or Zapier if you prefer their tool routers.
- Authorize with your Hunter account or API key.
- Back in a chat, ask Claude to find or verify emails — it’ll use the MCP server to hit Hunter’s API.
Because this is a custom MCP server rather than a first-party directory connector, remote custom connectors on claude.ai require a paid plan; the local setup runs through Claude Desktop or Claude Code.
The limits that actually matter
The MCP server is good at pulling Hunter into a conversation. But its shape is “an assistant you operate,” not “an agent that runs.” Three limits define it:
- No triggers, no monitoring. The server only works inside a conversation you start. There’s no “when a new lead lands in the CRM, find and verify their email” or “enrich every signup automatically.” Nothing fires on an event — you have to be there, prompting.
- Conversation-only. Claude finds and verifies when you ask; it doesn’t sit watching your pipeline and enriching new contacts on its own. Close the chat and nothing continues.
- Laptop-bound for anything scheduled. The closest thing to “running on its own” is Claude Cowork’s scheduled tasks, which fire on a fixed clock and only “while your computer is awake and the Claude Desktop app is open.” That’s not an always-on, event-driven prospecting agent.
So Claude is great for “find and verify these emails right now” and not built for “enrich every new lead the moment it lands.”
If you want Hunter work that runs on its own: Carly
The moment you want something to happen around Hunter without you in the chat — enrich a lead the instant it signs up, verify a list on a schedule, route the results to the right place, follow up automatically — you’ve crossed past what Claude’s MCP server is for.
That’s where Carly fits. Carly is an AI executive assistant built to act on triggers, not just answer in a chat:
- Fires on events, 24/7, in the cloud — when a new lead lands, Carly finds and verifies; your laptop doesn’t need to be awake.
- Connects Hunter to the rest of your stack — route enriched contacts as part of a workflow that also touches email, calendar, CRM, and tasks.
- Actually sends and updates — drafts and sends email (Gmail and Outlook) with attachments, files and labels, manages tasks, updates your CRM, and records meetings.
- Builds the workflow for you — tell it “I’d like to set up a system that finds and verifies the email for every new signup, then adds them to the CRM” in plain English; it interviews you, then builds it with you. No prompt engineering.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. Carly connects to 200+ tools across 40+ categories — see integrations. By the way, Carly also integrates with Hunter.
Claude’s Hunter MCP vs Carly
| Claude (Hunter MCP) | Carly | |
|---|---|---|
| Find emails | Yes | Yes |
| Verify addresses | Yes | Yes |
| Acts on triggers / events | No | Yes |
| Enriches new leads on its own | No | Yes |
| Works while laptop is closed | No | Yes (cloud) |
| Sends email as part of the flow | No (Gmail draft-only) | Yes (Gmail + Outlook) |
| Pricing | Pro $20 / Max $100–$200 | AI agents from $35/mo |
Claude’s MCP server is a strong Hunter lookup inside a chat. Carly is a teammate that enriches leads and acts as they arrive.
Frequently Asked Questions
Does Claude integrate with Hunter?
Yes. Hunter ships an official MCP server (plus a Claude plugin, and connections via Composio and Zapier) that links Claude to your Hunter account — Claude can find emails, verify addresses, search by domain, and enrich companies inside a chat. You add it as a custom MCP server (it’s not a one-click directory connector), and like all MCP setups it only works inside a conversation you start.
Can Claude act on Hunter automatically?
No. The MCP server works inside a conversation you start — there are no event triggers, so Claude won’t enrich a new lead or verify a list on its own. For automatic, trigger-based Hunter work, you need an agent platform like Carly.
How do I connect Claude to Hunter?
Get your Hunter API key, then add Hunter’s official MCP server as a custom connector (via the Hunter plugin) or connect through Composio or Zapier. Authorize with your account, then ask Claude to find or verify emails in a normal chat.
Is the Hunter MCP server free?
The MCP server is free to connect, but lookups and verifications consume your Hunter plan’s credits. Adding a remote custom connector on claude.ai requires a paid Claude plan; the local setup runs through Claude Desktop or Claude Code.
What if I want Claude to monitor my pipeline and enrich leads when they land?
That’s outside what Claude’s MCP server does — it looks up emails inside a chat, it doesn’t monitor or act on triggers. Carly fires on events 24/7 in the cloud and can enrich new leads, verify addresses, update your CRM, send email, and more. 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."
