MCP server

Verify addresses from AI assistants over the Model Context Protocol.

Kavik ships a Model Context Protocol server so AI assistants (Claude, ChatGPT, and others) can verify addresses with your account.

Endpoint: https://mcp.kavik.email/mcp (Streamable HTTP, stateless JSON)

Authentication

Two options:

  • API key: your X-API-Key header as usual, or Authorization: Bearer eva_..., against https://mcp.kavik.email/mcp.
  • OAuth: use https://mcp.verifications.email/mcp for now. The authorization server currently issues tokens for that resource only; assistants that follow the OAuth metadata spec will fail against mcp.kavik.email until the backend accepts both resources. API-key auth works on both hosts today.

Tools

Eight tools cover single verification, list verification, bulk job creation, job status, job results, domain deliverability, usage, and job listing. Every tool call consumes the same quota as the equivalent API call, on every plan including Free (the Free plan’s 300 monthly verifications are the trial).

Rate limits and error shape match the REST API. See Getting started for a first call, then point your assistant at the endpoint with your key.
