Checks if a website is WebMCP ready — validates tools, contracts, forms, and security. WebMCP Ready Checker is a developer tool that scans any web page and tells you how well it implements the WebMCP specification — the emerging standard for exposing website functionality to AI agents. Click the extension icon to open the side panel, hit "Scan this page", and get an instant readiness score (0–100) across five categories: **What it checks:** - Detection — Is navigator.modelContext available? Are tools registered? - Page Coverage — Do registered tools cover forms, search, action buttons, filters, and content listings? - Tool Contracts — Are tool names valid snake_case? Are schemas well-formed with typed properties and descriptions? - Security — No secrets in tool definitions? Proper readOnlyHint annotations? Consent for risky actions? - Declarative Forms — Are form tools configured with toolname, tooldescription, and labeled fields? **Features:** - One-click scanning from the side panel - Overall score with per-category breakdowns - Actionable fix suggestions with copy-paste code snippets - Discovered Tools inventory showing every registered tool with its full schema - Page Overlay mode — highlights covered (green) and uncovered (red) interactive elements directly on the page - Cross-linking between tool cards and their check results for fast navigation - Full Report page with scoring methodology explanation - Export as JSON or PDF for sharing with your team **Who is this for?** Web developers implementing WebMCP on their sites. If you're adding AI agent support to your web application using the WebMCP API (navigator.modelContext), this tool helps you validate your implementation and find gaps before agents try to use your site. **Privacy:** All analysis runs locally in your browser. No data is sent to any server. The extension reads page DOM structure only when you click "Scan" — it does not collect, store, or transmit any browsing data.
