What it does
An MCP server that exposes read-only access to the DecimalAI public skills registry, which ranks agent skills by measured benchmark performance rather than popularity. It provides three tools for searching, retrieving, and ranking agent skills, and is aimed at developers building or evaluating AI agents who want evidence-based skill selection.
- Search the public registry for agent skills by keyword or semantic query to find candidates for a specific task category.
- Retrieve the full record for a specific skill, including its trust and safety scan status, benchmark lift data, and SkillScore.
- Browse a ranked leaderboard of skills sorted by effectiveness metrics such as biggest improvement or efficiency to compare options.
Tools this server exposes
| Tool | Does |
|---|---|
| search_skills | Performs a hybrid keyword and semantic search over the public skills registry with optional category and sort filters. |
| get_skill | Returns the full registry record for a skill by slug, including safety scan status, benchmark lift, SkillScore, ratings, and SKILL.md content. |
| get_leaderboard | Returns a ranked list of skills sorted by a chosen metric such as skill_score, biggest_improvement, efficiency, or top_rated, with optional category and time-wi |
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.
