v2.0.0 — Documentation API, Docs Panel & MCP Server

v2.0.0 — Documentation + Agent Intelligence Layer

Live: https://libwatch.vercel.app

New: Documentation API

• GET /api/library-docs?library=<name> — README + CHANGELOG for any npm package or GitHub repo (owner/repo). Falls back to GitHub raw when the npm registry omits its readme field. 5-minute cache.
• GET /api/library-resolve?q=<query>&limit=<n> — ranked library search across npm registry and GitHub repositories. 60-second cache.

New: MCP tool server (POST /api/mcp)

• Stateless Streamable-HTTP JSON-RPC endpoint for AI coding agents (Cursor, Claude Code, Codex, etc.)
• resolve-library-id — finds the right library from a natural-language query
• query-docs — fetches current documentation for a specific library
• Supports protocol versions 2024-11-05 / 2025-03-26 / 2025-06-18

New: Docs panel in the dashboard

• Resource inspector now has Metadata / Docs / Raw tabs
• Docs tab renders README + CHANGELOG inline via react-markdown + remark-gfm
• Raw tab shows the exact JSON payload for inspection

Architecture

• server/cache.ts — generic in-memory cache helpers (per-key TTL)
• server/registry.ts — shared docs + resolution providers (npm + GitHub) used by REST and MCP
• server/mcp.ts — stateless JSON-RPC handler (no long-lived sessions required for serverless)
• Permissive CORS headers added globally for API + MCP clients
