Comment on an item

Comment on an item

Posts an update, monday.com's comment, on an item, or a reply to an existing update, with optional mentions.

Note: body takes HTML such as <b> and <br>, not Markdown. Mention users, teams or boards with mentionsList, never with @ in the body.

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

Call the MCP tool create_update.

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

API (official)

• Base URL: https://api.monday.com
• Endpoint: POST /v2
• Auth: send the header Authorization: $MONDAY_TOKEN
• Docs: https://developer.monday.com/api-reference/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.
