## 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 Buildkite.
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 Buildkite account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## TL;DR

### How Atomic Agent connects to Buildkite
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 Buildkite to Atomic Agent

### Connect Buildkite to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- 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.
- Ask Atomic Agent to do something in Buildkite. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Buildkite 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 Buildkite MCP server, and what's possible with it?

The Buildkite MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Buildkite account. It provides structured and secure access to your CI/CD platform, so your agent can perform actions like verifying API access, retrieving build metadata, and listing connected pipeline agents on your behalf.
- API token verification and management: Instantly confirm the validity, scopes, and details of your current Buildkite API token for secure automation and troubleshooting.
- Buildkite API metadata retrieval: Fetch essential API metadata, including webhook IP addresses, to support your organization's firewall and security configurations.
- Connected agent discovery: List all pipeline agents linked to your Buildkite organization, enabling dynamic monitoring and management of your CI/CD infrastructure.
- Organization-wide agent filtering: Apply filters and pagination when retrieving agents, making it easy to manage large deployments and pinpoint specific resources.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `BUILDKITE_GET_CURRENT_ACCESS_TOKEN` | Get Current Access Token | Tool to retrieve the authenticated API access token details. Use when you need to confirm the validity and scopes of the current API token. |
| `BUILDKITE_GET_META` | Get Meta | Tool to retrieve metadata about the Buildkite API. Use when you need to fetch webhook IP addresses for firewall or security configurations. |
| `BUILDKITE_GET_USER` | Get User | Tool to retrieve details about the current authenticated user. Use when you need to get information about the user account that owns the API token. |
| `BUILDKITE_LIST_ORGANIZATIONS` | List Organizations | Tool to list all organizations the current user is a member of. Use when you need to discover available organizations or get organization slugs for other operations. |
| `BUILDKITE_LIST_PIPELINE_AGENTS` | List Pipeline Agents | Tool to list connected agents for an organization. Use after confirming the organization slug. Supports optional filtering and pagination. |

## 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](/pricing) for the current limits that apply to your connection.

## Complete Code

## Conclusion

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

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Buildkite MCP?

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

### Can I use Tool Router MCP with Atomic Agent?

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 Buildkite tools.

### Can I manage the permissions and scopes for Buildkite while using Tool Router?

Yes, absolutely. You can configure which Buildkite 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.

### How safe is my data with Composio Tool Router?

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 Buildkite data and credentials are handled as safely as possible.
