WebMCP Gen

Author website-specific WebMCP tools by writing a manifest, compiling it to an init script, and validating that Chrome registers and invokes the tools.

This skill does not call a nested agent. You are responsible for exploring the page, writing manifest.json, and iterating based on validation output.

Setup check

From the skill directory, install dependencies if they are not already installed:

cd skills/webmcp-gen
pnpm install

This installs the pinned Stagehand package plus the TypeScript toolchain (tsx, typescript, ) used to run the generated .
