v0.2.0 — catalog mode: 665 endpoints in ~300 tokens

Highlights

Catalog mode. Exposing every endpoint as its own MCP tool floods the model's context. Catalog mode exposes just two tools, search_api and call_api.

GitHub REST spec (665 GET operations)	Tools	Approx. context
Default mode	665	~147,000 tokens
Catalog mode	2	~300 tokens

Try it on the demo: https://web2mcp.cwei59969.workers.dev/mcp?mode=catalog, or set TOOL_MODE = "catalog" for your own deployment.

One-click deploy. The Deploy to Cloudflare button now asks for an AUTH_TOKEN and explains each setting, so a fresh deployment is protected from the start.

Also

• scripts/openapi2connector.js: fixed an infinite loop when truncated tool names collide
• Published to the official MCP Registry as io.github.charleswei118/web2mcp
• Zero runtime dependencies, as before

Full notes in CHANGELOG.md.
