Lets Claude or ChatGPT check your Smartlead cold email campaigns, leads, mailboxes and replies, and act on them after you confirm.

This is Smartlead's own way to let Claude or ChatGPT work with your cold email account. You can ask how campaigns are doing, which leads replied, which mailboxes have sending problems, or why a domain lands in spam. You connect by signing in to Smartlead and clicking Allow, and the assistant only sees the account you sign in with. It can also send email and delete data, but Smartlead says it asks you to confirm first.

Good for

  • Teams running cold email outreach in Smartlead
  • Sales leads who want campaign and reply-rate reports without exporting data
  • Anyone fixing deliverability: spam placement, bounces or disconnected mailboxes

Install Smartlead MCP

Claude Code

  1. 1

    Copy this prompt.

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

claude mcp add --transport http smartlead https://mcp.smartlead.ai/mcp

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 Sign-in with the vendor account (OAuth).

Smartlead's docs do not cover this app. These steps use the sign-in address the Smartlead server accepts; you sign in to Smartlead and click Allow when asked. To cut access later, remove the server from this app's settings.

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

Tools

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

Pros and cons

Good

  • Built and hosted by Smartlead, with nothing to install for Claude or ChatGPT
  • You sign in with your Smartlead account and click Allow; no API key to copy
  • Covers campaigns, leads, mailboxes, inbox replies and deliverability checks
  • Asks you to confirm before sending email or deleting data
  • Easy to revoke: delete the MCP key in Smartlead and access stops right away

Watch out

  • No read-only mode
  • Smartlead publishes no list of the tools it offers
  • Only Claude and ChatGPT have setup guides
  • The older Claude Desktop method keeps your API key in plain text
  • Requests count against your Smartlead plan's API quota

Permissions

medium risk · 3 things to watch

Medium risk

Your assistant can send emails from your mailboxes and delete data in your account, so a wrong instruction could reach real prospects. Read every confirmation before you approve it, and connect the account you mean to change.

What it can do

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

Watch out for

  • It can send email and delete data

    Smartlead says the assistant asks before it sends email or deletes data. Read each confirmation before you say yes. helpcenter.smartlead.ai

  • The older method puts your API key in the address

    With the config file method the key sits in plain text in the file. Do not share or screenshot it, and delete the key in Smartlead if it leaks. helpcenter.smartlead.ai

  • Heavy use can hit your plan's API limit

    Limit errors come from your Smartlead plan's API quota. Check your usage in Smartlead if requests start failing. helpcenter.smartlead.ai

Technical details
Turning on read-onlyNo read-only mode is documented. Smartlead says the assistant asks for confirmation before any action that sends email or deletes data.
Talks tohttps://mcp.smartlead.ai
Sign-in and keysSmartlead lists each connection as a key named 'MCP: Claude...' or 'MCP: ChatGPT...' under Settings > API Key Management; delete it to cut access. The older method keeps your API key in the server address in your Claude config file.
Scopes

  • The one Smartlead account you sign in with during setup

Alternatives

Use Smartlead's own server unless you need a local tool you can inspect; it is official and needs no key. LeadMagic's package is the most downloaded community option but archived, and Instantly's server fits outreach run on Instantly.

Questions

Does Smartlead have an official MCP server?

Yes. Smartlead hosts its own server and documents how to connect it to Claude and ChatGPT. Community servers on npm and GitHub are not made by Smartlead.

Can Claude or ChatGPT send emails from my Smartlead account?

Yes, but only after you confirm. Smartlead says the assistant always asks before sending any email.

Can it delete my campaigns or leads?

It can delete data, but not without your approval. Smartlead says any action that deletes data asks you to confirm first.

Do I need a Smartlead API key?

Not for the Claude connector or ChatGPT: you sign in to Smartlead and click Allow. Only the older Claude Desktop config file method needs a key, from Settings > API Keys in Smartlead.

What is the Smartlead MCP server URL?

The Claude and ChatGPT sign-in flow connects for you, so you do not need to type an address. For apps where you add a server by address, the server accepts sign-in at https://mcp.smartlead.ai/mcp, which Smartlead's docs do not list. The older documented address is https://mcp.smartlead.ai/sse?user_api_key=YOUR_API_KEY, used through Claude Desktop's config file.

How do I disconnect Smartlead from Claude or ChatGPT?

Disconnect it in the assistant's connector or plugin settings. Or, in Smartlead, open Settings > API Key Management and delete the key named "MCP: Claude" or "MCP: ChatGPT"; access stops right away.

I connected the wrong Smartlead account. What do I do?

Disconnect it, then connect again and sign in with the right account. The assistant only sees the account you sign in with.

Why do I get limit errors?

Your Smartlead plan's API quota is used up. Check your plan or usage in Smartlead.

I can't find Smartlead in Claude. What now?

Smartlead says to search for it under Connectors and to contact its support if it does not appear. You can also use the older config file method in Claude Desktop shown in the install box.
