Api Key

Temporal is a cloud-native workflow orchestration platform for building reliable distributed applications. It ensures workflows run reliably, scale automatically, and recover from failures.

Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Temporal.

This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Temporal account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Temporal

Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.

Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

Connect Temporal to Atomic Agent

  1. Sign up or sign in to the Composio dashboard. Copy your API key.
  2. In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
  3. Ask Atomic Agent to do something in Temporal. It searches Composio for the right tool.
  4. On first use, open the sign-in link returned in the chat. Connect your Temporal account, then return to Atomic Agent to continue.

Headless setup

Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY

What is the Temporal MCP server, 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.

Use Temporal from Atomic Agent

With your account connected, ask Atomic Agent to work with Temporal in natural language. You can connect more apps through the same Composio integration as you need them.

Visit the Atomic Agent website or inspect the Atomic Agent source code.

Troubleshooting

Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See Composio pricing for the current limits that apply to your connection.

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. Atomic Agent 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.
