crawlgraph-mcp
Five MCP tools for backlink research using CrawlGraph
and Common Crawl snapshots: backlinks, backlink_changes, gap_analysis,
gap_outreach_targets, and releases. Outreach tools identify research
candidates; they do not send messages or create contacts.

Your API key in Authorization: Bearer cg_live_… |

Account-linked OAuth access token in the Authorization header | Bounded directory profile, when enabled |
Legacy /mcp also accepts Smithery's ?apiKey=… and base64 JSON ?config=…
forms. Header credentials take precedence, then apiKey, then packed config.
Prefer the Authorization header. The connector endpoint rejects API keys,
query credentials and packed configuration; OAuth tokens never go to the
public /api/v1 API.
Directory approval and real Claude/OpenAI compatibility verification remain pending. No Verified listing or logo is claimed.
