`@yichus/mcp`

Local relay that opens curated calculators and the playground with WebMCP enabled. It is not published to npm; build it from a checkout with pnpm run yichus-mcp:build and run node packages/yichus-mcp/dist/cli.js, as the CLI reference shows. The tool list comes from packages/yichus-mcp/src/server.ts, and calculator slugs are generated into calculators.ts from the deploy manifest.

yichus_list_calculators — List curated Yichus calculators (and the playground) with slugs and titles.
yichus_open_calculator — Open a calculator or the playground in the browser with ?webmcp=1 enabled.
