The cold email MCP server for AI agents

Natural-language control

Ask in plain English (“pause my two worst campaigns”) instead of writing HTTP calls or clicking through a dashboard.

Hosted, zero setup

Nothing to install or run locally. Point your client at one URL with your API key and the tools appear automatically.

Scoped and revocable

Every action uses an API key you control. Use a read-only key for analysis; a read_write key can also spend credits, order infrastructure and send replies. Revoke access instantly whenever you want.

Your key, your scope

Every key is read-only or read_write, with nothing in between, enforced by the backend, not by the MCP layer. A read-only key can use the read tools plus three that buy and change nothing (the connection check, audience sizing and Lead Finder search) and gets HTTP 403 on everything else. A read_write key can use every tool, including the ones that spend credits, order domains and mailboxes, approve Autopilot runs and send replies to prospects.

Revoke any time

Delete a key in API & MCP in the side menu and the agent loses access immediately. Every call is authenticated with that key.

Annotated tools, money flagged

Read-only tools are marked safe and delete tools destructive, so MCP clients can run reads freely and prompt you before actions that change your data. The tools that spend real money (purchase_credits, create_dfy_order, approve_autopilot_run) say so in their own descriptions.

Same limits as the API

Every call runs through the REST API with the same authentication and rate limits, so an agent can never exceed them.
