Send a message

Send a message

Sends a message from a channel to its recipients right away; on the API this starts a new conversation.

Note: Sends for real. On MCP it sends a draft made with create_draft, which must have at least one recipient. The API token needs the Send permission, and the MCP connection the send scope.

Set up

Use the first option your agent supports.

MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

{ "mcpServers": { "front": { "url": "https://mcp.frontapp.com/mcp" } } }

Call the MCP tool send_message.

Server URL: https://mcp.frontapp.com/mcp

Note: Connect with the client ID and secret of a Front developer app that has MCP Server access: Front has no dynamic client registration.

API (official)

• Base URL: https://api2.frontapp.com
• Endpoint: POST /channels/{channel_id}/messages
• Auth: send the header Authorization: Bearer $FRONT_API_KEY
• Get a key: https://dev.frontapp.com/docs/create-and-revoke-api-tokens
• Docs: https://dev.frontapp.com/reference/introduction

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
