Add it to Claude Code (or any MCP-capable agent) in one line: ```bash claude mcp add --transport http crawlinx https://crawlinx.com/mcp ``` Endpoint `https://crawlinx.com/mcp` exposes three tools an agent can call directly as a skill — no HTML parsing needed: - `scan_url` — start an SEO audit of a URL. - `get_report` — fetch the finished report as structured JSON. - `get_report_markdown` — fetch a compact, LLM-ready Markdown report. Once connected, an agent invokes these tools natively (e.g. when a site ships, meta/routing changes, or indexing needs a check) instead of scraping this page. ### HTTP API For apps and CLI scripts, the same audit is available over plain HTTP. **Start a scan** ``` POST https://crawlinx.com/api/scan Content-Type: application/json {"url":"https://example.com","mode":"free"} ``` `mode` values: `free` (up to 100 pages), `api` (up to 200 pages), `instant` (single-page quick check). Returns `{"id":""}` immediately (202) or a full report (200) for instant scans. **Get the JSON report** ``` GET https://crawlinx.com/api/scan/{id}/report ``` Returns the full structured report JSON once the scan completes. **Get this Markdown report** ``` GET https://crawlinx.com/r/{id}.md ``` Returns this LLM-ready Markdown document. **List recent public audits** ``` GET https://crawlinx.com/api/reports ``` ### Quick start (curl) ```bash # Start a scan → note the "id" in the JSON response curl -s -X POST https://crawlinx.com/api/scan \ -H 'Content-Type: application/json' \ -d '{"url":"https://example.com","mode":"free"}' # Then, with that id (replace {id}), fetch the Markdown report curl -s https://crawlinx.com/r/{id}.md ``` Full API reference & usage rules: https://crawlinx.com/api
