Webmcp

Implement WebMCP

Expose site tools to AI agents via the browser using the WebMCP API (Chrome blog).

Requirements

• Call navigator.modelContext.registerTool() for each tool you want to expose
• Each tool needs name, description, inputSchema (JSON Schema), and an execute callback
• Tools should expose your site's key actions (search, navigation, data retrieval)
• Use an AbortController signal to unregister tools when no longer needed
• The API is detected via browser rendering — ensure the script runs on page load

Validate

POST https://isitagentready.com/api/scan
Content-Type: application/json
