Send a Chat message

Send a Chat message

Posts a message to a ClickUp Chat channel, such as an alert for a team, and returns the message.

Note: Needs the channel's id: find it with clickup_get_chat_channels first. On the API, type (message or post) is required.

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": { "clickup": { "url": "https://mcp.clickup.com/mcp" } } }

Call the MCP tool clickup_send_chat_message.

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

API (official)

• Base URL: https://api.clickup.com/api
• Endpoint: POST /v3/workspaces/{workspace_id}/chat/channels/{channel_id}/messages
• Auth: send the header Authorization: $CLICKUP_API_KEY
• Get a key: https://app.clickup.com/settings/apps
• Docs: https://developer.clickup.com/docs/authentication

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.
