How do I connect Muse and Claude so they can hand each other work?

Once you give it a routine. On 8 October 2026, each of two tasks Muse handed Claude started its routine within a second. Without a routine, Claude picks the task up when you talk to it.

Offhand does not put Muse inside Claude, or Claude inside Muse: each works in its own app, under its own sign-in, and the two meet on your to-do list.

What both can do is add an MCP server. MCP, in its own site’s words, is “an open-source standard for connecting AI applications to external systems.” A server added to both is one place that both of them reach. Anthropic describes adding one to Claude in Get started with custom connectors using remote MCP; Muse adds one as a custom connector.

Both connect to the same address, https://offhandapp.com/mcp, and each gets only what you leave ticked on the Offhand page it connects through. The steps for each are on its own page.

In Muse, say:

Hand ‘Fix the price script that rounds to the wrong cent’ to Claude in Offhand.

Muse calls add_task with assignTo set to Claude. The task goes on your list, marked for Claude.

Claude starts on its own once you give it a routine in Claude’s Routines with an API trigger and only the Offhand connector, made on a computer. Offhand shows how once Claude is connected. Claude takes the task, then answers at done or blocked, with one line.

Every call in between, step by step: How do I hand a task from one AI agent to another?

In Claude, say:

Hand ‘Check the chair listing for replies’ to Muse in Offhand.

Claude calls add_task with assignTo set to Muse. Muse finds it at its next check, every 5 minutes, as the message you send it when you connect asks. Muse has no webhook to start it at once, so a task handed to it waits at most 5 minutes. It takes the task, then answers at done or blocked, with one line.

Muse’s pickup was tested on 24 October 2026: it found a task Claude Code handed it at its next check, and finished it 5 minutes later.

Making each agent start on its own: How do I make an agent start on its own when it’s handed a task?

Ask the one that handed the task over:

What did Claude say about the price script in Offhand?

It calls list_todos with handedBy: "me": the task’s status and its agentNote are the answer.

You don’t have to ask either of them. Every task one hands the other is also on your own list, with its name on it.

The rest, every call and every refusal, is on the docs page.
