pmcp: Instructions Hiding in Your Dependencies

Field notes

pmcp scans installed dependency trees for SKILL.md files instead of relying on a manually maintained registry. Its three-tool MCP surface separates catalog browsing, lexical problem matching, and opening a single skill body, while recognized locations include several agent-specific directories and package-level skills folders. The default operation uses no model and does not download assets; semantic indexing is described as an optional command requiring a separately installed encoder. The page also distinguishes dependency-shipped skills from subscription-supported skills authored by the project.
