Overview

AI-generated overview

Lets an assistant verify email addresses by MX records, scrape website contacts, and search LinkedIn jobs and YouTube data through RapidAPI.

What it does: Wraps four LeadHarbor RapidAPI listings as MCP tools: verify_email checks syntax, typos, disposable/role/free flags, MX and SPF/DMARC; extract_website_contacts pulls emails, phones and social links from a site's home, contact and about pages; search_linkedin_jobs and get_linkedin_job query public logged-out LinkedIn job listings; and search_youtube, get_youtube_channel and get_youtube_video return YouTube search results, channel uploads and video metadata.
When to use it: Useful for lead generation and prospecting work: checking whether an email domain can receive mail, gathering contact details from company sites, and pulling public job postings or YouTube channel and video data into an assistant session.
Requirements: Runs locally over stdio, typically started with npx, so Node.js is needed. Requires a RapidAPI key supplied in the RAPIDAPI_KEY environment variable, with an active subscription to the LeadHarbor listings; RapidAPI handles billing. Network access is required for all tools.

Before you install

The RAPIDAPI_KEY is a billable credential: usage is metered and charged through RapidAPI, so a leaked or shared key can incur costs. Email verification is MX-only and never contacts the mailbox, so it cannot confirm an address exists or detect catch-all domains. Website contact extraction and LinkedIn job lookups send third-party URLs and queries to RapidAPI, and LinkedIn's guest endpoint can be rate-limited.

Installation

In SourceWeft

Open Leadharbor Mcp in the dashboard and add it to a workspace.
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.
