What it does
Registry MCP server for SuperSkill, a platform to find, inspect, and install reviewed AI-agent capabilities. Developers use it to search the harness catalog, fetch resource details, and integrate reusable agent tools into their workflows.
- Search and discover reusable agent capabilities by name or topic across the SuperSkill registry.
- Retrieve detailed information about a specific harness including its manifest, trust profile, and installation instructions.
- Install a reviewed agent capability into Claude or Codex with verified permissions and quality gates.

Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
