# Blockquote

> Blockquote scores a public URL 0-100 for how likely ChatGPT, Perplexity and Google AI Overviews are to cite it, and returns the fixes. The skills below are served over the Model Context Protocol (Streamable HTTP) at https://mcp.blockquote.io/mcp. Blockquote runs no A2A JSON-RPC endpoint, so the interface below declares the MCP binding it does serve, not an A2A one.

## Skills
- **Start an AI-citability scan** — Scan a public HTTPS URL for AI citability. Returns a scan id at once; poll get_scan until the status is done.
- **Get scan status and report** — Read a scan by id as a summary, as the complete report JSON, or as one Markdown document.
- **List all citability checks** — The catalog of every check a scan runs, with what it measures and why it matters.
- **Explain one check in depth** — What one check measures, why it matters for AI citation, and the typical fix.
- **Audit agent readiness** — Audit how well AI agents can find, read and use a domain, an MCP server or an MCP App. Returns a score, evidence per check and a fix for each failure.
- **Get an agent-readiness report** — Read a stored agent-readiness report as a summary, JSON or one Markdown document.
- **Account plan and usage** — Plan, limits and scans used today and this month for the API key in the Authorization header.
- **Compare two scans of one URL** — What changed between two finished scans of one page: score deltas, flipped checks, and resolved, new and open recommendations.
- **List monitored URLs** — The URLs this account re-scans weekly, each with its last score and run time.
- **Add a URL to the weekly monitor** — Add a public HTTPS URL to this account's weekly re-scan. Monitoring needs a paid plan.
- **Stop monitoring a URL** — Remove one monitor by its id. Weekly re-scans of that URL stop; the reports it produced stay readable.
