Promptdna MCP Agent Skill

Search, fetch, compose, and contribute reusable AI prompt blocks through the PromptDNA MCP server (mcp.promptdna.org) — a community library of 950+ community-contributed prompt components spanning business, creative, financial, legal, medical, scientific, and software domains. Use this when a task calls for an existing well-tested prompt fragment (persona, constraint, eval, task template, etc.) or for assembling a full prompt from vetted parts rather than writing one from scratch. Every tool call is credit-metered — check the cost table below before calling anything.

How to use it

Copy the folder

Take aiskillstore/promptdna-mcp from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.
