Runx vs Skillmd

A side-by-side look at the Runx and Skillmd MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Verdict: choose Runx for developer tools work; choose Skillmd for developer tools as a local process. You can also run both side by side in one mcpServers block.

Skillmd tools 7

  • skillmd_searchSearch the SkillMD registry of Agent Skills (SKILL.md files) by task, name or keywords. Returns matching skills with their owner/name slug, description, category, safety verdict and install snippet, best match first.
  • skillmd_getFetch one skill by owner/name slug, including its SKILL.md body, provenance (source repo and pinned commit), license, safety verdict and capability flags.
  • skillmd_installInstall a skill by owner/name slug: validates it, then writes one canonical copy (.agents/skills/<name>) and links it into the chosen agents' skill directories. Never executes scripts. The response reports the skill's capability flags (docs_only, network_calls, executes_scripts, reads_secrets) as information.
  • skillmd_trendingTop skills on the SkillMD leaderboard, ranked by installs, saves and ratings, optionally within one category and time window.
  • skillmd_recommendRecommend skills. With based_on set to a skill's owner/name slug, returns the top skills in that skill's category (excluding itself); without it, returns what is trending over the last 30 days.
  • skillmd_list_savedList the signed-in user's saved skills. Requires the SKILLMD_TOKEN environment variable (a SkillMD personal access token).
  • skillmd_lintValidate a SKILL.md against the SkillMD format and return diagnostics, capability flags and a 0-100 quality score. Pass raw SKILL.md content, or a registry slug (owner/name) to fetch and lint that skill.
