Use emailvalidation with AI agents (MCP)
emailvalidation ships a hosted Model Context Protocol (MCP) server. AI agents and assistants — Claude, Cursor, VS Code and any other MCP-capable client — can call the API as native tools, no SDK or glue code required.
https://api.emailvalidation.io/mcp
Connect in seconds
Using Claude Code:
claude mcp add --transport http emailvalidation https://api.emailvalidation.io/mcp --header "apikey: YOUR_API_KEY"
Or add it to any MCP client configuration:
{
"mcpServers": {
"emailvalidation": {
"url": "https://api.emailvalidation.io/mcp",
"headers": { "apikey": "YOUR_API_KEY" }
}
}
}
All requests, including listing the available tools, need your API key. Sign up for a free API key and send it as the apikey header.
Available tools
| Tool | Endpoint | Description |
|---|---|---|
getInfo | GET /v1/info | Validate an email address |
createBulkJob | POST /v1/bulk | Submit a list for bulk verification |
listBulkJobs | GET /v1/bulk | List your bulk jobs |
getBulkJob | GET /v1/bulk/{job_id} | Get a bulk job’s status |
deleteBulkJob | DELETE /v1/bulk/{job_id} | Delete a bulk job |
getStatus | GET /v1/status | Account quota status |
Every bulk endpoint is a tool except the results download: a completed job’s results can run to 100,000 rows, too large for a tool result, so download them from the job’s links.results over the REST API. createBulkJob takes the list as the emails array; CSV and TXT file uploads are only available over the REST API.
Tool calls are metered like regular API requests and return the same machine-readable errors, so your agent always knows how to proceed. Full details in the MCP documentation.
