Google Spark MCP Skills Registry

A 24/7 Model Context Protocol (MCP) server providing on-demand agent skills to Google Spark (Gemini Spark).

Hosted on Render for always-on availability, allowing Spark to dynamically query and apply skills anytime—even when your personal computer is turned off.

Features

• 24/7 Cloud Availability: Hosted on Render as a lightweight Node.js web service.

• On-Demand Dynamic Loading: When you tell Spark "use ui-ux-pro-max" or "audit with ponytail", Spark calls get_skill to fetch that specific skill's guidelines in real time.

• 63+ Portable Upstream Skills Included:

  • ui-ux-pro-max + CKM Suite: 7 design & styling skills (79 design styles, 192 palettes, 22 stacks).

  • obra/superpowers: 14 core agent workflows (TDD, systematic debugging, planning, worktrees).

  • mattpocock/skills: 35+ architecture and code quality skills (code review, specs, tickets).

  • DietrichGebert/ponytail: 6 anti-overengineering and debt-tracking skills.

  • heygen-hyperframes: Video generation quickstart workflow.
