Run SendFox from Claude, ChatGPT, or Codex

Connect SendFox to your AI assistant and manage your list in plain English — add contacts, tag and segment, draft and send campaigns, build automations, and check your stats, all without leaving the chat.

Every plan can connect — nothing new to install. On the Free plan the assistant gets a limited set of tools: reading your account, lists, campaigns and stats, adding and tagging contacts, and transactional email. Upgrade to unlock the rest.

I'm using

Your SendFox connection URL (the same for every client):

In Claude, open Settings → Connectors → Add custom connector.
Paste the connection URL above and save.
Claude opens a SendFox sign-in page — approve it and you're connected.

Add the server with one command:

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

Or add it to your project's .mcp.json:

{
  "mcpServers": {
    "sendfox": {
      "type": "http",
      "url": "https://sendfox.com/mcp"
    }
  }
}

Then run /mcp inside Claude Code to sign in and authorize SendFox.

In ChatGPT, open Settings → Connectors → Add, choose a custom connector, and paste the connection URL above. (Custom connectors require a ChatGPT plan that supports them.)

Building on the OpenAI API instead? Add SendFox as an MCP tool on a Responses request:

{
  "type": "mcp",
  "server_label": "sendfox",
  "server_url": "https://sendfox.com/mcp",
  "require_approval": "never"
}

Add the server to ~/.codex/config.toml:

[mcp_servers.sendfox]
url = "https://sendfox.com/mcp"

Start Codex — it opens a browser to sign in and authorize SendFox.

Connecting takes one click — no API key to copy. Full access needs a paid plan, and you can revoke it anytime from your connected apps.

What you can ask for

The connection covers everything the SendFox API does. A few things to try:

“Add [email protected] to my Newsletter list and tag her as VIP.”
“Draft a campaign to my Newsletter list, but skip anyone tagged Churned.”
“How did my last campaign do — opens and clicks?”
“Set up a welcome automation for new subscribers.”
“Import these 50 contacts and put them on my Waitlist.”

It can manage contacts, lists, tags, segments, campaigns, automations, forms, custom fields, and sending domains. Every action runs against your account only, and normal sending, approval, and plan limits still apply.
