Integration

Sender integration

Sender (sender.net) is an email and SMS marketing platform. Manage subscribers (create, update statuses and custom fields, delete, group membership, activity history), groups, segments and custom fields; create, schedule, send, copy and delete email campaigns and read their opens, clicks, bounces, unsubscribes and spam reports; create and send transactional emails and read their reports; list automation workflows, their steps and statistics, and add a subscriber to a workflow; record custom events; and manage webhooks (paid plans). Authentication is an API token from the Sender account settings, sent as a Bearer token.

Connect Sender How integrations work

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in Sender.Built from the 66 Sender tools below, on the connection you add once.

What you can do with Sender

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Use Sender from Claude Code, Cursor or Codex

Connect Sender in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Sender operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

Set up the MCP server step by step

How to connect Sender

Create your workspace
Sign up free. Nothing to install.
Connect Sender once
Add your Sender connection in Settings. Every tool from this integration reuses it, and secrets are encrypted at rest and visible only to you.
Describe the job in chat
The workflow builds itself in front of you and picks the endpoints it needs. Drag the steps yourself on the canvas whenever you would rather be explicit.
