Hunter.io + Cursor
Find and verify email addresses via Hunter.io. 7 tools for domain search, email finder, email verifier, account stats. Bearer-token / query-key auth.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
HUNTER_API_KEY
Step 1 — Get credentials
io API v2 (hunter.io/api-documentation/v2).
Setup:
- Sign in to https://hunter.io → top-right avatar → API → API Keys.
- 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)
Step 2 — Install the adapter
git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d
Step 3 — Add the connector in Cursor
Cursor reads MCP servers from ~/.cursor/mcp.json. Add this entry:
{
"mcpServers": {
"anythingmcp": {
"url": "https://cloud.anythingmcp.com/mcp",
"headers": { "Authorization": "Bearer YOUR_MCP_API_KEY" }
}
}
}
- Get your MCP API key from AnythingMCP → Profile → MCP API Keys → New Key.
- Save the file and restart Cursor.
- Open Cursor → Settings → MCP to verify
Hunter.iois listed and "Connected". - Start chatting — all
Hunter.iotools are now invokable.
