## 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 Realphonevalidation.
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 Realphonevalidation 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 Realphonevalidation
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 Realphonevalidation to Atomic Agent

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

The Realphonevalidation MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Realphonevalidation account. It provides structured and secure access to advanced phone number and email verification services, so your agent can perform actions like real-time phone validation, carrier checks, bulk number scrubbing, and email deliverability checks on your behalf.
- Instant phone number validation: Let your agent verify if a phone number is active, its type (mobile or landline), carrier, and caller details in real time.
- Bulk number scrubbing: Automatically process and validate large lists of phone numbers, checking for connectivity and type to ensure data accuracy at scale.
- Email address verification: Have your agent check if an email is deliverable and not disposable, helping prevent bouncebacks and spam risks.
- Reassigned and consent compliance checks: Enable your agent to determine if a number has been reassigned since a specific consent date for regulatory compliance.
- Carrier and wireless identification: Easily identify whether a US phone number is wireless or landline for TCPA compliance and segmentation.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `REALPHONEVALIDATION_CHECK_FRAUD` | Check Phone Fraud Risk | Tool to check phone number for fraud risk using Fraud Check API. Provides a phone risk score and many actionable data points including phone type, carrier, location, and recommendation (block, flag, allow). Use when you need to identify possible fraudulent phone numbers. US numbers only. |
| `REALPHONEVALIDATION_EMAIL_VERIFY` | Email Verification | Tool to validate an email address and check connectivity and disposability. Use after gathering an email to ensure it's deliverable and not disposable. |
| `REALPHONEVALIDATION_LOOKUP_DNC` | DNC Lookup | Tool to check Do Not Call list status for US phone numbers. Determines if number is on National, State, or DMA Do Not Call lists, identifies cell vs landline, and checks for known TCPA litigators. Requires SAN number from FTC. |
| `REALPHONEVALIDATION_RPV_ACTIVE` | Check Phone Active Status | Tool to determine if a phone number is active on a valid phone service provider. Use after collecting the user's phone number for real-time verification. |
| `REALPHONEVALIDATION_RPV_REASSIGNED_NUMBER_LOOKUP` | Reassigned Number Lookup | Tool to check if a phone number has been reassigned since a given consent date. Use when verifying number ownership status after obtaining user consent. |
| `REALPHONEVALIDATION_RPV_SCRUB_PLUS` | Scrub Plus Phone Numbers | Tool to scrub a phone number for connection status and type. Use to validate a US phone number's status and line type. |
| `REALPHONEVALIDATION_RPV_WIRELESS_ID` | Wireless ID | Tool to identify whether a US phone number is landline or wireless. Use when conducting TCPA compliance checks. |
| `REALPHONEVALIDATION_VALIDATE_PHONE_SCRUB` | Validate Phone Number (Scrub) | Tool to validate US phone numbers using budget-friendly Scrub API. Determines connectivity status quickly (under 2 seconds). Best for organizations with large lists/databases on tight budgets that only need connection status. Optional Iscell and Carrier fields available for additional charge. |
| `REALPHONEVALIDATION_VALIDATE_PHONE_TURBO_STANDARD` | Validate Phone Turbo Standard | Tool to perform real-time US phone validation using Turbo Standard API. Provides connection status and phone type (Mobile, Landline, VoIP). Optimized for web forms and apps when only connection status and phone type are needed. Faster than Turbo V3 when only basic validation is required. Returns results in about 2 seconds. |
| `REALPHONEVALIDATION_VALIDATE_PHONE_TURBO_V3` | Validate Phone Turbo V3 | Tool to perform comprehensive real-time phone validation using Turbo V3 API. Returns connection status, phone type (landline, cell, VoIP), carrier ID, caller name (when available), and caller type (consumer, business). Use when complete phone data overview is required in web forms. US numbers only. |

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

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

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

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