Sent MCP Server

The Sent MCP server exposes every messaging primitive — send, lookup, contacts, templates, and analytics — directly inside your AI coding agent. No API keys to paste, no context-switching to another tab. Your agent can send a real SMS, look up a contact, or check deliverability without leaving your editor.

The MCP server is available at mcp.sent.dm. It implements the Model Context Protocol over HTTP with OAuth 2.1 authentication.

Setup

Add the MCP server to your agent

Pick your agent below and follow the one-time setup.

Run this command in your terminal:

claude mcp add --transport http sent https://mcp.sent.dm/mcp

That's it. Claude Code registers the server and handles authentication on first use.

Open or create ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) and add the sent entry:

{
  "mcpServers": {
    "sent": {
      "type": "http",
      "url": "https://mcp.sent.dm/mcp"
    }
  }
}

On Windows the config file is at %APPDATA%\Claude\claude_desktop_config.json.

Restart Claude Desktop after saving.

Open or create ~/.cursor/mcp.json and add:

{
  "mcpServers": {
    "sent": {
      "url": "https://mcp.sent.dm/mcp"
    }
  }
}

Restart Cursor after saving. The server will appear under Settings → MCP.

Add a .vscode/mcp.json file at the root of your project (or your user settings):

{
  "servers": {
    "sent": {
      "type": "http",
      "url": "https://mcp.sent.dm/mcp"
    }
  }
}

VS Code Copilot will pick up the server automatically on next activation.

Authenticate

The first time your agent calls a Sent tool, it will trigger an OAuth 2.1 authorization flow:

Your agent opens a browser tab to app.sent.dm/mcp-authorization
You log in with your Sent account and select the organization and sender profile to grant access to
An access token is issued and stored by the agent — no copy-pasting required

The token has no expiry. To revoke access, go to Dashboard → Settings → MCP Connections and deactivate it from there.

Use it

Ask your agent anything that involves messaging:

Send a WhatsApp message to +1234567890 using the order_confirmation template
with customerName="Alex" and orderNumber="#9981"

Look up the phone number +447911123456 and tell me what channel it supports

Show me deliverability stats for the last 7 days

The agent selects the right tool, constructs the call, and shows you the result inline.

Authentication details

The Sent MCP server uses OAuth 2.1 with PKCE (RFC 7636) and Dynamic Client Registration (RFC 7591). Your agent registers itself automatically — no manual client ID setup required.

Token expiry: None. Tokens are long-lived.
Revocation: Dashboard → Settings → MCP Connections → Deactivate.
Scope: Tied to a specific organization and sender profile chosen during authorization. To grant access to a different profile, re-authorize.
