Overview

AI-generated overview

Wraps the Hunter.io API so an assistant can search domains, find and verify professional emails, enrich people and companies, and manage leads.

What you can do
Provides 11 tools over the Hunter.io v2 API: account_info for plan and credit usage, domain_search for emails at a company, email_finder and email_verifier, email_count, and person, company and combined enrichment (optionally Clearbit-compatible). Discover finds companies from natural-language or structured filters, and list_leads reads the leads list. Every tool returns plain JSON with status, summary, result, proof and warnings.
When to use it
Useful when an assistant needs professional contact data: finding or verifying an email for outreach, enriching a person or company record, prospecting companies by industry, size or technology, or reviewing existing Hunter leads.
Requirements
Runs locally over stdio, typically via npx @scalably-io/hunter-mcp or the .mcpb desktop bundle. Requires a Hunter.io account and the HUNTER_API_KEY secret; optional HUNTER_API_BASE, HUNTER_TIMEOUT_MS and HUNTER_RETRY_BASE_MS tune the endpoint, timeout and retry backoff. Network access to the Hunter API is needed, and usage consumes plan credits.
Before you install
The API key is a billable credential: searches, verification and enrichment consume Hunter plan credits, and quotas are visible through account_info. create_lead writes to your Hunter leads list and is the only non-read tool; the other 10 are read-only. Queries send domains, email addresses and LinkedIn handles to Hunter.io.

Installation

In SourceWeft

  1. Open Hunter MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.
