What is the MyEmailVerifier MCP Connector?

The MyEmailVerifier MCP Connector lets you connect Claude.ai to real-time email verification using the Model Context Protocol. You can verify single emails or batches of up to 10 addresses directly inside Claude without leaving your workflow.

How do I connect MyEmailVerifier to Claude.ai?

Open Claude.ai Settings → Integrations → Add MCP Server, paste the connector URL https://mcp.myemailverifier.com, click Connect, enter your MyEmailVerifier API key, and click Authorize.

Is my API key safe with the MCP Connector?

Yes. The connector uses OAuth 2.0 PKCE authentication. API keys are held only in memory for the OAuth token lifetime (1 hour) and are never stored permanently. All traffic is encrypted via TLS.

What email verification features does the MCP Connector support?

The MCP Connector supports single email verification (verify_email) and batch verification of up to 10 emails (verify_email_batch). Both tools return deliverability status, SMTP validation, disposable domain detection, catch-all detection, and role-based address detection.

Security

Authentication

This connector uses OAuth 2.0 with PKCE (RFC 7636). Each user authenticates with their own MyEmailVerifier API key — the server never stores credentials permanently. Tokens expire after 1 hour.

Endpoint	URL	Purpose
Authorization	`https://mcp.myemailverifier.com/authorize`	Redirect user to login & consent
Token	`https://mcp.myemailverifier.com/token`	Exchange code for Bearer token
MCP	`https://mcp.myemailverifier.com/mcp`	Streamable HTTP — tool execution endpoint

ℹ️ The MCP endpoint accepts Streamable HTTP (POST) requests authenticated via OAuth 2.0 Bearer token. Protocol version: 2024-11-05.

Limits

Rate Limits

Limits are applied per IP address to ensure fair usage and service stability.

Endpoint	Limit	Window
OAuth endpoints	20 requests	per minute
MCP tool calls	30 requests	per minute
