Lets your AI assistant run your Instantly cold email: campaigns, leads, replies, analytics and sending accounts.

This is Instantly's own server, hosted by Instantly. Connect it with your Instantly API key and Claude, Cursor or n8n can create campaigns, add and move leads, read and answer replies, and pull campaign analytics. There is nothing to install. Before you connect, know that a full-access key also lets it send email and change live campaigns, so give the key only the scopes you need.

Good for

  • SDRs and founders who want campaign stats and unread replies by asking Claude
  • Agencies managing many Instantly campaigns who want bulk pauses, lead moves and reports in one chat
  • Growth teams building n8n agents that create leads and campaigns automatically
  • Anyone writing cold email with Claude who wants the result loaded straight into Instantly

Install Instantly MCP

Claude Code

  1. 1

    Copy this prompt.

    Add the Instantly MCP server to Claude Code. Run this command:

claude mcp add --transport http instantly https://mcp.instantly.ai/mcp --header "Authorization: YOUR_API_KEY"

Then check that it loaded and tell me if I need to sign in or restart.
  2. 2

    Paste it into Claude Code. It shows the change and asks before running it.

Requires Instantly plan with API access, Instantly API v2 key.

Read-only mode: Instantly does not document a read-only mode. A key with read scopes only should stop the assistant from changing anything, since every tool uses that key, but test it before you rely on it.

Replace YOUR_API_KEY with an API v2 key from Instantly's Settings, Integrations, API Keys. Give the key only the scopes you need. The key goes in the Authorization header, which Instantly recommends. Instantly's docs give only the generic address and header for this app.

Built from the package data we hold. Not yet tested by us.

Tools

We don't list Instantly MCP's tools here yet. After you connect it, ask your assistant "What can you do with Instantly MCP?" to see them.

Pros and cons

Good

  • Made and hosted by Instantly, so there is nothing to install or update.
  • Covers the whole Instantly API: accounts, campaigns, leads, emails, analytics and webhooks.
  • No extra charge on top of a plan with API access.
  • API key scopes let you limit what the assistant can do.
  • Works in apps that cannot send headers, using the key-in-address option.

Watch out

  • Needs an Instantly plan that includes API access.
  • Sign-in is by API key only in the docs; no account sign-in yet.
  • A full-access key can send email and change live campaigns.
  • The key-in-address option can leak the key into logs.
  • No published list of every tool; it mirrors the API reference.

Permissions

high risk · 4 things to watch

High risk

With a full-access key the assistant can send replies, launch or pause campaigns and change workspace settings. Create a key with only the scopes you need; Instantly does not document a read-only mode, so test a read-scope key before relying on it.

What it can do

  • Read your data
  • Create and change things
  • Delete things
  • Read-only mode

Watch out for

  • It can send email and change live campaigns

    With a full-access key the assistant can start or pause campaigns, reply to and forward emails, and add or move leads. Give the key only the scopes you need. developer.instantly.ai

  • It can manage API keys and members

    The tools cover the whole Instantly API, including workspace, member and API key endpoints. Leave those scopes off the key. developer.instantly.ai

  • A key in the address can leak

    The address-with-key option can end up in logs. Use the header option when your app supports it. developer.instantly.ai

  • Your config file holds your key

    Do not share or commit MCP config files that contain it. developer.instantly.ai

Technical details
Turning on read-onlyNo documented read-only mode. Inferred, not confirmed by Instantly: an API v2 key created with read scopes only (Settings > Integrations > API Keys) should limit the tools to reading, because every tool calls the Instantly API with that key.
Talks tomcp.instantly.ai
Sign-in and keysYour API key is stored in your AI app's connector settings or MCP config file.
Scopes

  • API v2 key scopes chosen when you create the key

Alternatives

Use Instantly's own server; it is hosted, covers the whole API and costs nothing extra. The community server only makes sense if you need to run the code yourself.

Questions

What is the Instantly MCP server URL?

https://mcp.instantly.ai/mcp, with your API key in the Authorization header. If your app cannot add headers, use https://mcp.instantly.ai/mcp/YOUR_API_KEY instead.

Is the Instantly MCP server free?

There is no extra charge. You need an Instantly plan that includes API access, because it works through your API key.

Where do I get the API key?

In Instantly, open Settings, then Integrations, then API Keys, and create an API v2 key. You choose its scopes there.

Can I make it read-only?

Not officially. Instantly does not document a read-only mode. A key created with read scopes only should keep the assistant to reading analytics and leads, but test it before you rely on it.

Can it send emails or launch campaigns on its own?

Yes, with a full-access key. It can reply to and forward emails, start and pause campaigns, and add or move leads. Claude asks before each action unless you set that tool to always allow.

Is it safe to put my API key in the URL?

Only if your app has no other option. Instantly warns that a key in the address can be recorded in logs; the header option keeps it out of them.

How do I check that it is connected?

Ask your assistant to list your email accounts in Instantly. If it returns them, you are connected.

Does it work with n8n?

Yes. Instantly's help center shows how to add it to an n8n AI agent workflow.

How do I add it to Claude?

Use the custom connector steps in the setup box above, with the address that ends in your API key.
