DeepDeck ships a WebMCP directory with pinned revisions: build inspectable browser tools for sites without APIs
j032 · reddit · 2026-09-14
The maintainer of DeepDeck, an MIT-licensed macOS desktop app built on DeepSeek Harness (independent, not official DeepSeek), launched a small WebMCP tool directory with four entries: Airbnb China, Hacker News, X, and an in-development NGA forums tool. Each entry points to GitHub source and a pinned revision, so you can inspect what you install and keep that version until you choose to update.
How it works: these are WebMCP-style tools inside DeepDeck's browser runtime — not remote MCP servers for any MCP client, and not an endorsement that target sites adopted WebMCP. For sites without native tools, DeepDeck's builder explores the page, generates a local TypeScript tool, and validates tool calls; saved tools are scoped to the site's origin and can be inspected, disabled, or rolled back.
Practical example: save a tool for fetching a Hacker News thread's comments and parent relationships, then reuse that interface in other sessions instead of rebuilding the extraction.
Honest caveats: site changes can break adapters, maintenance has ongoing cost, and the directory's value today is source/revision visibility, not coverage.
