Heroku Platform MCP Server

This server wraps the Heroku CLI instead of calling the platform API directly, so it inherits the authentication and permissions the CLI already has rather than opening a second access path. Its 32 tools cover the app lifecycle, dyno scaling and restarts, add-on provisioning, pipeline promotion and maintenance mode. A separate group targets Heroku Postgres: running SQL, listing active queries and locks, finding expensive statements and managing backups.
