Hunter.io + Claude

Find and verify email addresses via Hunter.io. 7 tools for domain search, email finder, email verifier, account stats. Bearer-token / query-key auth.

Requisitos previos

Las instrucciones de configuración completas están incluidas en el conector (visibles en el store al seleccionarlo). Las variables de entorno requeridas:

HUNTER_API_KEY

Paso 1 — Obtener credenciales

io API v2 (hunter.io/api-documentation/v2).

Setup:

  1. Sign in to https://hunter.io → top-right avatar → API → API Keys.
  2. Copy the key. Set HUNTER_API_KEY.

Authentication: query-string ?api_key=... on every call (QUERY_AUTH). Hunter also accepts the API key in an X-API-Key header but query-string is the documented default.

Credits model: every request consumes credits per your plan. domain_search is the most expensive (returns up to 100 emails per call); email_verifier and email_finder are 1 credit each. email_count and account are FREE (don't deduct).

…(continued in the in-app connector instructions)

Paso 2 — Instalar el adapter

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d

Paso 3 — Añadir el conector en Claude

Ruta recomendada — funciona en claude.ai web sin tocar ningún archivo de configuración.

  1. Abre claude.ai/customize/connectors.
  2. Pulsa "Add custom connector".
  3. Rellena:
    • Name: Hunter.io
    • URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → pega tu MCP API key (de AnythingMCP → Profile → MCP API Keys → New Key)
  4. Pulsa Connect para autorizar.
