Update a task

Update a task

Changes a task's name, assignee, due date, description, completion or custom fields, leaving every other field as it was.

Note: The MCP tool updates up to 50 tasks per call.

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": { "asana": { "url": "https://mcp.asana.com/v2/mcp" } } }

Call the MCP tool update_tasks.

Server URL: https://mcp.asana.com/v2/mcp

API (official)

• Base URL: https://app.asana.com/api/1.0
• Endpoint: PUT /tasks/{task_gid}
• Auth: send the header Authorization: Bearer $ASANA_ACCESS_TOKEN
• Get a key: https://app.asana.com/0/my-apps
• Docs: https://developers.asana.com/reference/rest-api-reference

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.
