Find and verify contact emails associated with a domain using free discovery methods first and APIs when keys are available. Triggers on domain email scans, contact discovery, email pattern finding, and email enrichment.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Email Finder ## Overview Discover email addresses associated with a domain using a hybrid approach: free methods first (web scraping, pattern guessing, WHOIS lookup), then APIs (Hunter.io, Apollo.io, etc.) when keys are available. ## When to Use - Scan a domain to find associated emails - Find contact emails for a company - Replace email hunter functionality - Find email patterns for a domain - Verify email addresses - Enrich contact data with discovered emails ## Project Context Discovery Before finding emails: 1. Check for existing email discovery tools 2. Review available API keys (Hunter.io, Apollo.io) 3. Check compliance/privacy requirements 4. Look for project-specific `[project]-email-finder` skill ## Methodology ### Free Methods (Primary) 1. **Web Scraping** - Scan `/contact`, `/about`, `/team` pages for emails 2. **WHOIS Lookup** - Query domain registration data 3. **Pattern Guessing** - Generate patterns from names found on site: - `firstname.lastname@domain.com` - `firstnamelastname@domain.com` - `firstname@domain.com` - `f.lastname@domain.com` ### API Methods (If Keys Available) | API | Env Variable | Purpose | |-----|-------------|---------| …

How to install
mdr add genfeedai/skills/email-finder@sha256:e76bffec767d3f05The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
