crawlgraph-mcp — Claude Code MCP server for backlink research
Looks up backlinks, compares domains with competitors, and checks link changes across Common Crawl snapshots. Use it for backlink research and gap analysis.
Open on GitHubWhat crawlgraph-mcp does
The server exposes five tools. backlinks looks up links to a domain, while backlink_changes compares snapshots. gap_analysis compares your domain with competitors; gap_outreach_targets returns candidates for research, and releases lists available snapshots. Outreach tools do not send messages or create contacts.
For local stdio, configure npx with -y crawlgraph-mcp and pass CRAWLGRAPH_API_KEY through the MCP environment. A valid API key is required to run tools. Quotas depend on account access: free accounts get 15 backlink calls and 0 gap jobs per UTC calendar month; accounts with current paid access get 1,000 calls and 50 jobs. Polling a gap job costs no gap jobs, but an accepted submission remains charged even if its response is lost.
What it helps with
- look up backlinks for a domain
- compare competitor links with your own domain
- check which backlinks changed between snapshots
- find outreach research candidates from a gap analysis
Example prompts for the agent
- Find backlinks for
example.com, sorted by authority. - Compare
example.comwithone.comandtwo.comin a gap analysis. - Check backlink changes for
example.combetween snapshots.
