WarmySender MCP MCP server

An official MCP server by WarmySender that allows AI agents to manage email warmup, monitor mailbox health and deliverability, analyze campaign performance, and handle contact management. It supports creating and launching multi-channel outreach campaigns (cold email, LinkedIn, Instagram, WhatsApp) via a scheduler that enforces rate limits and safety caps, ensuring agents do not send messages directly but orchestrate them safely.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http warmysender-mcp https://warmysender.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add warmysender-mcp --url https://warmysender.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable warmysender-mcp in your MCP settings.

      "url": "https://warmysender.com/mcp"
    }
  }
}
