## 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 Emailable.
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 Emailable 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 Emailable
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 Emailable to Atomic Agent

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

The Emailable MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Emailable account. It provides structured and secure access to your email verification services, so your agent can perform actions like real-time email validation, bulk batch checks, account monitoring, and verification status tracking on your behalf.
- Instant email address verification: Ask your agent to check if a single email address is valid, risky, or deliverable before you send that important message.
- Bulk batch email validation: Have the agent verify thousands of email addresses at once for newsletters, campaigns, or CRM imports, ensuring high deliverability rates.
- Batch job status monitoring: Let your agent track the progress and results of ongoing or completed batch verification jobs for timely follow-up actions.
- Account status and credit checks: Retrieve your Emailable account details, including owner info and available credits, to make sure you never run out of verification capacity.
- Seamless OAuth onboarding: Initiate the OAuth flow to securely grant your agent access to Emailable whenever needed, all without manual credential handling.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `EMAILABLE_GET_ACCOUNT_INFO` | Get Account Info | Tool to retrieve account information including owner email and available credits. Use when you need to confirm account status before sending email verifications. |
| `EMAILABLE_GET_BATCH_STATUS` | Get Batch Status | Tool to get the status and results of a batch verification job. Use after submitting a batch to check its progress. |
| `EMAILABLE_O_AUTH_AUTHORIZE` | Build OAuth Authorization URL | Build an OAuth 2.0 authorization URL for the Emailable authorization code flow. Returns a URL to redirect users to for authorization. Upon successful authorization, users are redirected to your redirect_uri with an authorization code (valid for 10 minutes) that can be exchanged for access tokens. |
| `EMAILABLE_VERIFY_BATCH_EMAILS` | Verify Batch Emails | Submit a batch of email addresses for asynchronous verification. Returns a batch ID immediately. Use this for bulk email validation (2 to 50,000 emails). For single emails, use EMAILABLE_VERIFY_EMAIL instead. The batch is processed asynchronously - use EMAILABLE_GET_BATCH_STATUS with the returned batch ID to check progress and retrieve verification results. |
| `EMAILABLE_VERIFY_EMAIL` | Verify Email | Tool to verify a single email address and return detailed results. Use when you need to check email deliverability and risk. |

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

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

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

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