Easy Email Verification for AI agents
Verify email addresses from claude.ai, ChatGPT and MCP clients such as Claude Code, or let your AI coding assistant write the integration from documentation made for agents.
Choose your tool
ChatGPT
Beta ChatGPT plugin, via MCP
Add our MCP server as a plugin in ChatGPT developer mode and sign in with your account (no key). Not in the plugin directory yet.
Get startedClaude
Beta Claude.ai, Claude Code and Claude Desktop, via MCP
In claude.ai, Claude Desktop or Claude Code, add our MCP URL and sign in with your account. No API key needed.
Get startedMCP server
Beta Model Context Protocol
Single, batch and bulk verification tools for any MCP client: sign in with OAuth, or send an X-API-Key header.
Tested with: Claude Code, claude.ai (OAuth), ChatGPT (OAuth)
Get startedAI coding assistants
Available REST API docs
Point Claude Code, Cursor, Copilot or Codex at agents.md and the OpenAPI spec to write a correct integration.
Get startedGemini
Beta Gemini CLI, via MCP
Add the MCP server to Gemini CLI in settings.json with your API key. The Gemini app (gemini.google.com) is not tested yet.
Get startedMCP server Beta
Endpoint https://mcp.easyemailverification.com/mcp (Streamable HTTP). Clients that support OAuth, such as claude.ai, ChatGPT and Claude Code, only need the URL: you sign in with your Easy Email Verification account. Other clients send an API key in the X-API-Key header. Tools: verify_email, verify_emails (up to 50), create_bulk_job (up to 10,000) with get_bulk_status, get_bulk_summary and delete_bulk_job, and get_credits; each verified address uses one credit.
Claude Code (then /mcp → Authenticate to sign in):
claude mcp add --transport http --scope user eev https://mcp.easyemailverification.com/mcp
claude.ai, ChatGPT, Cursor, VS Code, Codex, Windsurf, Gemini CLI and Claude Desktop: see the setup for each MCP client.
With an API key you can try it with eev_sandbox_key and addresses at sandbox.easyemailverification.com. Tested clients: Claude Code, claude.ai (OAuth), ChatGPT (OAuth).
For developers and AI coding assistants
Give your assistant these links instead of letting it guess the API:
- agents.md – setup guide for agents: API key, sandbox, single, batch and bulk verification, result handling, errors and security.
- llms.txt – index of the documentation for language models.
- llms-full.txt – the setup guide and the full API reference in one file.
- API reference – every endpoint, parameter, field and status code.
- openapi.json – the OpenAPI specification.
Ready-made prompts for verifying, cleaning files and integrating the API: prompt library.

FAQ
Which AI tools can use Easy Email Verification?
claude.ai and ChatGPT (sign in, no key), Claude Code, Claude Desktop, Gemini CLI and other MCP clients through our MCP server (tested with Claude Code, claude.ai (OAuth), ChatGPT (OAuth)), and any AI coding assistant through the REST API documentation in agents.md.
Do I need an account?
Yes, an Easy Email Verification account. In claude.ai, ChatGPT and Claude Code you sign in with it, with no API key. Other MCP clients and your own code use an API key from the dashboard; to try those first, use the public sandbox key eev_sandbox_key with addresses at sandbox.easyemailverification.com (no credits).
How are AI verifications charged?
Exactly like API calls: one credit per verified address, from your account. Each connected app has its own key and statistics in API settings. Checking your remaining credits is free.
Can my assistant walk me through the setup?
Yes. Paste claude.md, gemini.md or chatgpt.md into the assistant and it guides you step by step.
Where should my AI coding assistant start?
At agents.md: authentication, sandbox, single, batch and bulk verification, result handling and errors, with copy-paste examples. The full contract is in openapi.json.
