MCP server for email verification
Give AI agents and MCP clients a tool to validate email addresses. The remote MCP server uses your API key and the same credits, limits and rules as the REST API, including free unknown results.
Tools the server offers
| Tool | What it does | Credits |
|---|---|---|
validate_email | Validate one address: status, reason, recommended action and the detail fields. | 1 credit, unknown free |
get_credits | Read your credit balance and the credits that expire soonest. | Free |
create_bulk_job | Start a bulk job from up to 10,000 addresses sent inline. | 1 credit per unique definite result |
get_bulk_job | Follow a bulk job: progress, counts by status and when it finished. | Free |
Connect a client
Point your MCP client at https://api.email-validation.org/mcp and send your API key as a Bearer token. The setup guide has step-by-step instructions.
Create an API key
Sign up (you get 500 free credits) and create a key in your dashboard.
Add the server
Add a remote MCP server with the URL above and an Authorization header with your key.
Ask your agent
For example: "Check whether these sign-up addresses can receive mail and list the ones to remove."
{
"mcpServers": {
"email-validation": {
"url": "https://api.email-validation.org/mcp",
"headers": { "Authorization": "Bearer YOUR_API_KEY" }
}
}
}Limits and safety
- Up to 500 requests per second per account after your first purchase (20 before), shared with the REST API.
- Each check waits at most 15 seconds; slower checks return unknown and are free.
- Give an agent its own API key with a daily credit cap, and revoke it when you no longer need it.
- Machine-readable details: the server card and the AI catalog.
- OpenAPI 3.1 REST API: email verification API.
Frequently asked questions
Can AI agents use email-validation.org?
Yes. Our MCP server lets MCP-compatible AI clients validate addresses with your API key. It uses the same credits, limits and free-unknown rule as the API.
Which MCP transport does the server use?
It is a remote server that speaks Streamable HTTP and keeps no session state between requests. Clients authenticate every request with an API key in the Authorization header.
Does the MCP server cost extra?
No. Tool calls use the same credits as the REST API: one credit per definite result, and unknown results are free.
