MCP server for the LeadHarbor APIs on RapidAPI. Lets Claude, Cursor and other MCP clients call:
| Tool | What it does |
|---|---|
verify_email | Syntax, typo, disposable/role/free flags, MX, SPF/DMARC. MX-only: it never contacts the mailbox, so it cannot confirm an address exists or detect catch-all domains. |
extract_website_contacts | Emails, phones and social links from a site's home/contact/about pages |
search_linkedin_jobs / get_linkedin_job | Public LinkedIn job search and detail (logged-out guest endpoint; can be rate-limited by LinkedIn) |
search_youtube / get_youtube_channel / get_youtube_video | YouTube search, channel uploads, video metadata |
You need a RapidAPI key with a subscription to the LeadHarbor listings. RapidAPI handles billing; this server stores nothing.
