Architecture

​

Components

packages/
  core/   # PlayStoreClient, resource APIs, GPS_OPS
  cli/    # gps
  mcp/    # gps-mcp

​

Design

1. All Google Play API calls go through @appeeky/google-play-store-core.
2. CLI and MCP only adapt arguments and schemas.
3. New coverage is added in core, then registered in GPS_OPS so MCP tools and gps call stay in sync.
4. Dedicated CLI subcommands are convenience wrappers for common workflows; the registry is the complete catalog.

​

Extending

1. Add a method on the relevant resource class in core.
2. Register a GpsOp in the ops registry.
3. Optionally add a CLI subcommand.
4. MCP picks up the new tool automatically.
