What Crawlgraph MCP does
According to its repository: “Backlink lookups, competitor gap analysis and outreach-target discovery over the public Common Crawl webgraph via CrawlGraph.”
The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Crawlgraph MCP is listed under Marketing and SEO, a category of 63 servers in the directory, where it ranks #35 by stars.
Topics declared by the repository: ahrefs-alternative, backlinks, claude, common-crawl, cursor, gap-analysis.
Installing and connecting Crawlgraph MCP
Distribution modes declared in the official MCP registry:
- MCPB bundle (one-click install in Claude Desktop)
It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: TypeScript.
The registry lists one secret variable to provide (API key, access token). Keep them in the client's environment variables, never in a shared file or a repository.
Security: what to check
Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.
Points found for Crawlgraph MCP:
- Secrets: the server acts with your credentials. Create a dedicated key with minimum rights and an expiry date.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
