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 Verifiedemail account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Verifiedemail with - [OpenAI Agents SDK](https://composio.dev/toolkits/verifiedemail/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/verifiedemail/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/verifiedemail/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/verifiedemail/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/verifiedemail/framework/codex) - [OpenClaw](https://composio.dev/toolkits/verifiedemail/framework/openclaw) - [Hermes](https://composio.dev/toolkits/verifiedemail/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/verifiedemail/framework/google-adk) - [LangChain](https://composio.dev/toolkits/verifiedemail/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/verifiedemail/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/verifiedemail/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/verifiedemail/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/verifiedemail/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/verifiedemail/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/verifiedemail/framework/autogen) ## TL;DR ### How Atomic Agent connects to Verifiedemail 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 Verifiedemail to Atomic Agent ### Connect Verifiedemail 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 Verifiedemail. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Verifiedemail 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 Verifiedemail MCP server, and what's possible with it? The Verifiedemail MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Verifiedemail account. It provides structured and secure access to your email verification services, so your agent can perform actions like verifying email addresses, cleaning email lists, checking credit balances, and managing credential sharing on your behalf. - Real-time email verification: Instantly check the validity and deliverability of any email address, ensuring your messages reach real recipients. - Bulk email list cleaning: Automate the process of uploading and verifying large email lists to maintain high deliverability and reduce bounce rates. - Credit balance monitoring: Let your agent retrieve and monitor your remaining verification credits so you never run out unexpectedly. - Credential sharing and management: Fetch and update shared credentials securely, supporting workflows where multiple users need access or updates to verification data. - File verification status tracking: Poll and check the progress of bulk email verification jobs, helping you stay updated on list cleaning operations. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `VERIFIEDEMAIL_CHECK_CREDITS` | Check Credits | Tool to retrieve the remaining verification credits. Call before VERIFIEDEMAIL_VERIFY_EMAIL operations—especially in bulk or repeated workflows—as VERIFIEDEMAIL_VERIFY_EMAIL fails immediately when credits are exhausted. Use after confirming account authentication to ensure sufficient credits before proceeding. | | `VERIFIEDEMAIL_CHECK_FILE_STATUS` | Check File Status | Tool to check the status of a previously uploaded file. Use after uploading a file when polling for verification progress. | | `VERIFIEDEMAIL_GET1_CLICK_USER_DATA` | Get 1-Click User Data | Tool to retrieve data for a user who has completed a 1-Click Signup flow. Use after you have the identityUuid to fetch the verified user's full profile. | | `VERIFIEDEMAIL_GET_ENTITLEMENTS` | Get Entitlements | Tool to retrieve information about available credits across different entitlement types. Use when you need to check credit availability before performing operations that consume credits. | | `VERIFIEDEMAIL_GET_SHARED_CREDENTIALS` | Get Shared Credentials | Tool to retrieve a list of shared credential IDs. Use when you need to fetch all credentials shared to your account after authentication. | | `VERIFIEDEMAIL_LIST_DOWNLOADS` | List Downloads | Tool to get a list of previously created download requests. Use when you need to retrieve information about download requests that have been created for verification results. | | `VERIFIEDEMAIL_LIST_LISTS` | List Lists | Tool to get all email lists in your account. Use when you need to retrieve and view all verification lists with optional pagination and sorting. | | `VERIFIEDEMAIL_POST1_CLICK_CREDENTIALS_UPDATE` | Update 1-Click Credentials | Tool to update 1-Click credentials. Use after obtaining a 1-Click session uuid when you need to update user-provided credential values in a non-hosted or trusted flow. | | `VERIFIEDEMAIL_VERIFY_EMAIL` | Verify Email | Tool to verify the deliverability and validity of an email address. Use when you need to confirm if an email can receive mail by checking server existence, mailbox status, and more. For bulk use, call VERIFIEDEMAIL_CHECK_CREDITS first — this tool fails if verification credits are exhausted. | ## Supported Triggers None listed. ## 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 Verifiedemail from Atomic Agent With your account connected, ask Atomic Agent to work with Verifiedemail in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone Verifiedemail MCP server, the agents and LLMs can only access a fixed set of Verifiedemail tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Verifiedemail 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 Verifiedemail tools. ### Can I manage the permissions and scopes for Verifiedemail while using Tool Router? Yes, absolutely. You can configure which Verifiedemail 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 Verifiedemail data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
