Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Temporal account to Claude via Composio Connect, enabling it to start Temporal workflow to process order 12345, list running workflows for customer ACME Corp, cancel workflow execution with workflowId abc-789, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Connecting Temporal to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Claude Desktop connectors screen with Add custom connector selected

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Temporal account

Back in Claude, ask it to connect to Temporal or give it any Temporal-related task.

For example, ask Claude to:

  • "Start Temporal workflow to process order 12345"
  • "List running workflows for customer ACME Corp"
  • "Cancel workflow execution with workflowId abc-789"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Temporal account is ready to use.

What is the Temporal Claude Connector, and what's possible with it?

The Temporal MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Temporal account. It provides structured and secure access to your namespaces, workflows, schedules, workflow rules, batch operations, regions, and export sinks, so your agent can inspect workflows, manage schedules, control workflow executions, monitor operations, and review cloud resources on your behalf.

  • Workflow search and inspection: Have your agent find active or archived workflows, check their status and pending work, count matching executions, and review event history.
  • Workflow execution control: Direct your agent to cancel individual workflows or signal, reset, terminate, delete, and update options across selected workflows in batches.
  • Schedule management: Let the agent create, inspect, list, pause, unpause, trigger, backfill, or delete schedules, and preview their matching run times.
  • Namespace and region operations: Instruct your agent to review namespaces, capacity, assignments, and available regions, or manage namespace moves, regional failovers, and deletion when needed.
  • Rules, exports, and operation tracking: Have your agent manage workflow rules and history export sinks, then track batch jobs and asynchronous cloud operations through completion.

Troubleshooting

1. Why does Claude not use the Composio connector for Temporal?

The connector can show as connected, but Claude must use it in each Temporal conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Temporal again.

2. Why does Claude show an MCP server error before Temporal connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Temporal.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Temporal.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Temporal authorization link not work?

The Composio connector is one server. Your Temporal account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Temporal connection.
  • Composio creates a fresh Temporal authorization link.
  • Open that link in your browser and finish the Temporal sign-in.

4. Why do Temporal actions fail after they worked before?

The Temporal connection can expire or lose permission.

  • Ask Claude to inspect the Temporal connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Temporal account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Temporal.
  • If the action still fails with a permission error, check that the connected account has that permission in Temporal itself.

5. How do I switch to a different Temporal account?

Claude can manage the Temporal connection for you.

  • Ask Claude to disconnect or delete the current Temporal account.
  • Ask Claude to connect Temporal again.
  • Open the new Composio authorization link for Temporal.
  • Sign in with the other Temporal account in the browser.
  • After the account connects, ask Claude to retry the Temporal task.

6. Why is my Temporal connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Temporal connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Temporal tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Temporal.

FAQ

Frequently asked questions

With a standalone Temporal MCP server, the agents and LLMs can only access a fixed set of Temporal tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Temporal and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Temporal tools.

Yes, absolutely. You can configure which Temporal scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Temporal data and credentials are handled as safely as possible.
