WebMCP DevTools — Tool Inspector & Auditor

Inspect, audit and export WebMCP tools. Readiness scoring, performance profiling, code generation. By Wolvane.

WebMCP DevTools — inspect, test, audit and export the WebMCP tools a website exposes to AI agents. WebMCP (document.modelContext) lets websites register functions as "tools" for AI agents. This side panel shows you exactly what a page registers and helps you make it agent-ready. 🔧 Tool Inspector — Auto-detects imperative (registerTool) and declarative (<form toolname>) tools on any page. View schemas, parameters, descriptions and tool annotations (read-only, consequential, untrusted output) at a glance. ▶️ Execute — Run any tool from the panel with an auto-generated form, see results with JSON highlighting, and keep an execution history. 📊 Readiness Audit — 0-100 score for descriptions, input schemas, naming, titles, required fields and per-property docs, with concrete recommendations and an AI fix prompt you can paste into your assistant. ⚡ Performance — Per-tool latency (avg, P95), success/failure rate, slow-tool warnings and a benchmark runner for safe read-only tools. 🛡️ Security Checklist — Loose schemas (additionalProperties), high-risk actions without a consequential hint, sensitive parameters (passwords, keys), missing types and URL exposure. 📤 Export — Copy or download tool definitions as JSON schemas ready for LLM function calling, or as code snippets (cURL, TypeScript, Python). Audit and security reports export as Markdown or JSON. 🌐 Directory & Showcase — Keeps a local list of sites where you found tools, plus a curated showcase of public sites and official demos to try right away. 🌍 English and Turkish UI, dark/light/system themes. ⚙️ Requirements • Chrome 153 or later • Enable WebMCP: chrome://flags/#enable-webmcp-testing → Enabled → Relaunch (or visit a site enrolled in the WebMCP origin trial) 🔒 Privacy — Everything runs locally. No data collection, no external network requests. Built with ❤️ by Wolvane — wolvane.com Contact: info@wolvane.com
