Instantly MCP: The Official Server and What It Does
Yes — Instantly has an official MCP server. Instantly hosts a remote MCP server at https://mcp.instantly.ai/mcp that lets any MCP-compatible AI tool read and manage your cold email account by natural language — pull campaign stats, add leads, launch or pause sequences, check reply content, review sending account health. It authenticates with an API key you generate yourself, it’s included with your Instantly subscription, and setup takes a paste, not code. So if you’re searching “Instantly MCP,” the connection you want is real and it comes straight from Instantly.
The thing worth knowing before you set it up: an MCP server hands your outbound account to an AI inside a conversation you start. It’s a doorway, not a worker. Nothing watches Instantly for you, nothing fires when a prospect replies, and nothing runs while the chat is closed. Here’s exactly what the Instantly MCP does, how to turn it on, where it stops — and what to use when you want outbound work that runs on its own.
Looking beyond Instantly? MCP servers by category covers the rest.
What the Instantly MCP server does
Model Context Protocol (MCP) is the open standard that lets an AI client — Claude, ChatGPT, Cursor, and others — talk to an outside app through a shared interface. Instantly hosts its own remote server, so there’s nothing to build or run yourself. Instantly’s help center documents 31 tools across five categories: campaigns, leads, cold email, analytics, and account management.
With it connected, an AI client can:
- Read live campaign performance — “what’s the reply rate on the Q3 founders sequence?” answered from your actual account instead of a CSV export you pulled last Tuesday.
- Search leads and replies — “who replied this week and what did they say?” run against real data.
- Add and move leads — push a list of prospects into a campaign with custom variables filled in, or move someone between sequences.
- Manage campaigns and sending accounts — launch, pause, or archive a campaign; check inbox health and warmup status before you scale a sequence up.
It’s genuinely useful for ad-hoc work: ask a question, get an answer grounded in your real numbers, make a change on the spot without loading the dashboard.
One point of confusion worth clearing up: there are also community-built Instantly MCP servers floating around GitHub that predate the official one, and Instantly’s own blog covered one of them back in February 2026. Those still exist, but you no longer need to clone a repo and edit a JSON config file. The hosted server on Instantly’s own domain is the one to use.
How to set up the Instantly MCP server
The remote server is the quick path — no code, no hosting:
- In Instantly, go to Settings → Integrations → API Keys and generate an API key. API access is available on Instantly’s Email Outreach plans, and API v2 lets you scope a key so it can only do what you want it to.
- In your AI client’s connector settings, choose Add custom connector and point it at
https://mcp.instantly.ai/mcp, supplying your API key as the server expects. - Confirm the tools appear in the client, then start a chat and ask it to pull a campaign’s stats.
Instantly also publishes a short walkthrough course for the Claude setup. The AI can only do what the API key you issued allows — so if you want a read-only assistant that reports numbers but never touches a live campaign, scope the key that way.
Where the Instantly MCP stops
None of this is a knock on MCP — it’s just the shape of the protocol. Four limits show up the moment you want more than a conversation:
- It only works inside a chat you start. Close the window and nothing happens. The AI doesn’t watch Instantly; it waits for you to ask.
- No triggers. A prospect replying, a campaign’s bounce rate creeping up, a sequence finishing — none of these can start anything through MCP. There’s no “when this happens in Instantly, do that.”
- It’s one app at a time. The Instantly MCP knows Instantly. Getting a positive reply into your CRM, a Slack channel, and onto your calendar means wiring up (and authing) a separate MCP server for each, then hoping your client can juggle them in one turn.
- You own the key and the blast radius. The AI acts with whatever scope you granted it across your outbound account, and managing that is on you.
So the Instantly MCP is a great way to ask Instantly things and make one-off changes. It is not a way to make your outbound run — to have work happen on a schedule or in reaction to a reply, across the other tools a deal touches.
Running outbound work that doesn’t need a chat open
That “run on its own, across apps” gap is exactly where Carly fits. Carly connects to Instantly natively — no MCP server to point at, no config file to babysit — and to the ~260 other apps it supports, plus anything with a public API through your own key. The difference from MCP is the important part: Carly’s workflows are triggered and scheduled, so outbound work happens whether or not anyone has a chat window open.
A few things that MCP can’t do but a Carly workflow can:
- When a prospect replies → pause their sequence so they stop getting cold follow-ups, log the reply in HubSpot, create a deal if it’s qualified, and draft a personalized response.
- Every Monday morning → pull reply, open, and bounce rates for every active campaign and send you a summary with the underperformers flagged.
- When a new lead lands in a Google Sheet → add it to the right campaign with the custom variables filled in.
The non-AI steps — the moving, matching, and routing between apps — are free and unlimited, the Zapier-style backbone of the workflow. The AI steps (drafting, summarizing, deciding) start at $35/month. You describe the outcome in plain language and Carly wires up the Instantly connection and everything downstream.
If you just want to interrogate your campaign numbers from a chat, Instantly’s official MCP server is the right tool and it’s included with your plan. If you want Instantly to actually do things — on a reply, on a schedule, across every app a deal flows through — that’s the job MCP wasn’t built for, and it’s the one Carly was.
FAQ
Does Instantly have an official MCP server?
Yes. Instantly hosts a remote MCP server at https://mcp.instantly.ai/mcp, documented in its own help center. It’s built and maintained by Instantly, connects with an API key you generate in your account, gives MCP-compatible AI tools read and write access to campaigns, leads, replies, analytics, and sending accounts, and requires no code or hosting.
Is the Instantly MCP server free? Connecting it is free — you’re authorizing an AI client against your existing Instantly account and API key. You still need an Instantly plan with API access, which is available on the Email Outreach plans.
Can the Instantly MCP trigger automations? No. MCP is request/response inside an AI chat — it has no triggers and nothing runs when the conversation is closed. So it can’t pause a sequence the moment someone replies or alert you when a campaign’s numbers slip. For event- or schedule-driven outbound work across apps, you need a workflow tool like Carly rather than an MCP server.
Should I use the community Instantly MCP server on GitHub?
You don’t need to. Community servers predate Instantly’s official hosted one and require cloning a repo and editing a config file. Instantly’s own remote server at mcp.instantly.ai does the same job with a URL and an API key.
Can I connect Instantly to AI without coding or hosting a server? Yes. You don’t have to touch MCP at all. Carly connects to Instantly with your API key and lets you build the automation in plain language — describe what you want to happen and it wires up Instantly and the other apps involved, with no server to host and no code to write.

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."
