Frequently asked questions

What does Linkinator check?

Linkinator scans webpages and local files for broken links, supporting HTML, CSS, and Markdown content types. It can validate anchor fragments and follow links recursively within the same domain.

How do I install Linkinator?

The easiest way is to run `npx install-mcp linkinator-mcp --client claude` which automatically configures it for your MCP client. You can also install globally with `npm install -g linkinator-mcp` and add it manually to your client's config file.

Why isn't Linkinator appearing in Claude Code?

Check that the path in your config file is absolute, verify the build directory exists (`ls /path/to/linkinator-mcp/build/index.js`), and ensure Node.js is in your PATH.

How do I fix permission errors?

On macOS/Linux, run `chmod +x /path/to/linkinator-mcp/build/index.js` to make the build file executable.

What should I do if I get a port conflict?

When scanning local files, specify a different port using the `port` option (e.g., with `port 9000`).
