Instantly MCP servers: which one to use

Instantly hosts its own MCP server, and it is the one to use for most people. You paste an Instantly API key into Claude, Cursor or another client, with nothing to install. The server exposes the whole Instantly API, so a key with full access can send email and change live campaigns. For a safer start, vojtaupan's server is read-only until you switch writes on, and with the official server you choose the key's scopes when you create it.

Good for

  • SDRs and founders who want campaign stats and unread replies by asking Claude
  • Agencies managing many Instantly campaigns from one chat
  • Teams who want an assistant to read Instantly data without being able to send email
  • Developers who want to run the server themselves

Which Instantly MCP server to use

Use the official Instantly server with an API key that has only the scopes you need. Pick vojtaupan's instantly-ai-mcp if you want writes and sending off until you set a switch, or bcharleson's instantly-cli if you want a local server that is also a command-line tool.

Questions

Is there an official Instantly MCP server?

Yes. Instantly hosts it at https://mcp.instantly.ai/mcp and documents it in its developer docs. It exposes the Instantly V2 API as tools.

What is the Instantly MCP server URL?

It is https://mcp.instantly.ai/mcp, with your API key sent in the Authorization header. Instantly's docs also allow the key in the address as a last resort.

How do I add Instantly to Claude?

In Claude Desktop, open Settings, then Connectors, then Add custom connector, and enter https://mcp.instantly.ai/mcp/YOUR_API_KEY with your key in place of the placeholder. Instantly's quickstart uses the key-in-address form for Claude, so treat that address as a secret.

Do I need an API key?

Yes. Create an API v2 key under Settings, then Integrations, then API Keys in Instantly, and choose its scopes when you create it.

Can the Instantly MCP server send email?

Yes, with a key that allows it. The tools cover replying to emails and starting or pausing campaigns, so give the key only the scopes you need.

Which Instantly MCP server is read-only?

vojtaupan's instantly-ai-mcp. Its README says only 6 read tools are on by default, writes need INSTANTLY_MCP_WRITE=1, and the 4 tools that send email, activate campaigns or delete data also need INSTANTLY_MCP_ALLOW_DANGEROUS=1.

Is the key in the server address safe?

Prefer the header. Instantly's docs say the header keeps your key out of server logs and client history, and recommend the address method only if your client cannot set headers.

How are the bcharleson servers different from the official one?

Both run on your machine, not on Instantly's. instantly-mcp is a Python server whose README lists 38 tools in 6 categories. instantly-cli is a command-line tool that also starts as an MCP server with npx instantly-cli mcp, and its README lists 156 tools.

Is the Instantly MCP server free?

The server programs are free to run, and the two community servers are MIT licensed. You still need an Instantly workspace and an API v2 key.
