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 Circleci account to Claude via Composio Connect, enabling it to trigger a new pipeline on main branch, list all pipelines for backend service, get test results from last successful build, 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.

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.

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

bash
https://connect.composio.dev/mcp

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 Circleci account

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

For example, ask Claude to:

  • "Trigger a new pipeline on main branch"
  • "List all pipelines for backend service"
  • "Get test results from last successful build"

It will prompt you to authenticate and authorize access.

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

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

The Circleci MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Circleci account. It provides structured and secure access to your Circleci projects and pipelines, so your agent can trigger builds, fetch job artifacts, monitor workflows, and analyze test results on your behalf.

  • Automated pipeline triggering and management: Let your agent start new builds for specific branches or tags, enabling continuous integration workflows without manual intervention.
  • Workflow and job status monitoring: Ask your agent to fetch detailed information about jobs and workflows, including status, timing, and execution environment, to stay on top of your CI/CD processes.
  • Artifact and test result retrieval: Have the agent collect job artifacts or extract comprehensive test metadata and failure messages for easier debugging and reporting.
  • Pipeline and runner insights: Get your agent to list all pipelines for a project or enumerate available self-hosted runners, making it simple to manage and audit your Circleci resources.
  • User and configuration access: Retrieve user profile details or fetch pipeline YAML configurations as needed for documentation, troubleshooting, or workflow optimization.

Troubleshooting

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

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

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

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

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

  • 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 Circleci.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Circleci authorization link not work?

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

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

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

The Circleci connection can expire or lose permission.

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

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

Claude can manage the Circleci connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click and click Clear cache.
  • If Circleci 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 Circleci.

FAQ

Frequently asked questions

With a standalone Circleci MCP server, the agents and LLMs can only access a fixed set of Circleci tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Circleci 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 Circleci tools.

Yes, absolutely. You can configure which Circleci 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 Circleci data and credentials are handled as safely as possible.
