MCP server

Connect any MCP client in one config block

Run the open-source package locally, or use the hosted endpoint with nothing to install. Both expose the same tools behind your API key.

  1. 1

    Create an API key

    Open API keys in the dashboard. A sandbox key works too.

  2. 2

    Add the server to your client

    Paste the config into Claude Desktop, Cursor or any MCP client, or add the hosted URL.

  3. 3

    Ask in plain language

    "Verify this list", "Is this address real?", "Check our domain’s DMARC".

FAQ

AI agent tools, answered

What is the RocketVerifier MCP server?

MCP (Model Context Protocol) is an open standard that lets AI assistants call external tools. The RocketVerifier MCP server gives assistants such as Claude, ChatGPT and Cursor 14 tools for verifying addresses, running bulk jobs, checking credits and free domain lookups, so they can verify emails in the middle of a conversation.

How do I connect my AI assistant?

Run the open-source @rocketverifier/mcp package locally with npx and your API key, or point any client that supports remote MCP servers at https://api.rocketverifier.com/mcp with your key as a Bearer token. Step-by-step guides for each assistant are in the AI agents section.

Do agent tools cost credits?

Verifications use 1 credit per email, the same as the dashboard and API, and unknown results are never charged. The disposable, MX and domain authentication lookups are free.

Is there a CLI for scripts and CI pipelines?

Yes. @rocketverifier/cli runs single verifications, bulk jobs, uploads and downloads from the terminal. Add --json to any command to pipe the output into other tools or a coding agent.

Does it work with n8n, Clay and Zapier?

Yes. n8n has an official community node with a trigger node for RocketVerifier webhooks. In Clay, add an HTTP API enrichment column that calls the RocketVerifier API. Zapier works through the RocketVerifier Zapier app or a webhook step.

Can I test an agent without spending credits?

Yes. Use a sandbox key (rv_test_) with addresses at @sandbox.rocketverifier.com to get realistic, deterministic results at no cost.

Give your agent verified emails

Create a key, add the MCP server and ask your assistant to clean your next list.
