Why this exists

Tools like Ahrefs and Moz cost hundreds of dollars a month. This MCP gives you backlink research capabilities directly inside your AI assistant at zero cost, using:

• DuckDuckGo — mention discovery and prospect finding
• Wayback Machine CDX API — historical link data
• httpx + BeautifulSoup — page scraping and link verification

---

Tools

Tool	Description
find_mentions	Find all pages mentioning your domain (linked or unlinked)
find_prospects	Discover guest post, resource page, and roundup opportunities by niche
find_competitor_link_sources	Find pages linking to a competitor — prime outreach targets
verify_page_links	Scrape a URL to check if it links to you and extract contact info
extract_contact_info	Pull emails, social handles, and contact pages from any site

Requirements

• Python 3.10+
• No API keys needed
• No paid subscriptions

---

Limitations

• DuckDuckGo returns a sample of results, not a complete link graph
• Rate limiting: built-in 1.5s delay between searches to avoid blocks
• The Wayback CDX endpoint can occasionally return 503 or time out; check_page_history retries automatically
• Common Crawl graph data (full inbound link index) is not yet integrated — contributions welcome

Changelog (recent)

• 0.1.1 — Switched search from deprecated duckduckgo-search to the maintained ddgs package (same DuckDuckGo backend; fixes empty search results). Hardened Wayback CDX with HTTPS, longer timeouts, and retries.

---

Contributing

PRs welcome. High-impact areas:

• Common Crawl graph API integration for true inbound link discovery
• Broken link detection (find dead pages on prospect sites)
• Bulk processing (run across a list of URLs)
• Output to CSV / Google Sheets
