## 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 Bouncer.
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 Bouncer 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 Bouncer
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 Bouncer to Atomic Agent

### Connect Bouncer 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 Bouncer. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Bouncer 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 Bouncer MCP server, and what's possible with it?

The Bouncer MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bouncer account. It provides structured and secure access to your email verification and validation tools, so your agent can perform actions like real-time email validation, bulk verification, domain checks, and toxicity analysis for improved email deliverability.
- Real-time email verification: Instantly validate single email addresses to check deliverability and reduce bounce rates before sending messages.
- Bulk batch verification: Initiate, manage, and retrieve results from batch email verification jobs to clean and maintain large email lists efficiently.
- Toxicity analysis of email lists: Start and monitor toxicity analysis jobs to identify potentially harmful or problematic email addresses in your database.
- Domain verification: Check the validity and configuration of email domains, including MX records and catch-all status, to ensure emails reach their intended targets.
- Automated batch management: Finish, delete, or update batch verification and toxicity jobs to keep your verification workflows tidy and up-to-date.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `BOUNCER_CHECK_TOXICITY_LIST_JOB_STATUS` | Check Toxicity List Job Status | Tool to check the status of a specific toxicity list job. Use after creating a toxicity list job to poll its status until completion. |
| `BOUNCER_CREATE_BATCH_REQUEST` | Create Batch Request | Initiates an asynchronous batch email verification request. Use when you have multiple emails to verify. Returns a batch ID for tracking - use BOUNCER_GET_BATCH_RESULTS to retrieve verification results after processing completes, or provide a callback URL. |
| `BOUNCER_CREATE_TOXICITY_LIST_JOB` | Create Toxicity List Job | Tool to create a toxicity analysis job for a list of email addresses. Use when you need to batch-process toxicity checks for multiple emails at once. |
| `BOUNCER_DELETE_BATCH_REQUEST` | Delete batch request | Deletes a batch email verification request and all associated emails and results. Use when you need to permanently remove batch data. This operation is idempotent - calling it multiple times on the same batch ID is safe and returns success. Data is automatically deleted by Bouncer after 60 days if not deleted manually. |
| `BOUNCER_DELETE_TOXICITY_LIST_JOB` | Delete Toxicity List Job | Tool to delete a specific toxicity list job. Use when you need to remove a completed or unwanted toxicity analysis job after confirming its ID. |
| `BOUNCER_FINISH_BATCH` | Finish Batch | Tool to mark a batch verification process as finished early. Use when you need to stop batch processing before all emails are verified and reclaim credits for unprocessed emails. IMPORTANT: The batch must be in 'processing' status - cannot finish a batch that is 'queued' or already 'completed'. |
| `BOUNCER_GET_BATCH_RESULTS` | Get Batch Results | Tool to retrieve the results of a batch verification process. Use after submitting a batch to fetch all processed email verification outcomes. Note: If the batch is still processing, the API will return a 405 status indicating results are not yet available. Wait for the batch to complete before retrieving results. |
| `BOUNCER_GET_CREDITS` | Get Credits | Tool to retrieve the current credit balance for the account. Use when you need to check available credits before performing verification operations. |
| `BOUNCER_VERIFY_DOMAIN` | Verify Domain | Tool to verify the validity and configuration of a domain. Use when you need to confirm the domain's MX records and catch-all behavior. |
| `BOUNCER_VERIFY_EMAIL` | Verify Email | Tool to verify a single email address in real-time. Use when validating email entry form inputs instantly. |

## 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

None listed.

## Conclusion

### Use Bouncer from Atomic Agent
With your account connected, ask Atomic Agent to work with Bouncer 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 Bouncer MCP?

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

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

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