# PromptDNA **A community marketplace for composable AI prompt blocks — think npm for prompt engineering.** PromptDNA lets developers and AI agents discover, compose, fork, and contribute reusable prompt "blocks" — personas, task templates, constraints, reasoning chains, and output-format specifications that combine to build complete, battle-tested prompts. Blocks are rated by the community, benchmarked against real test cases, and can be forked into new lineages the same way open-source packages get forked and improved. - **Website:** https://promptdna.org - **MCP endpoint:** https://mcp.promptdna.org/v1/ ## What you can do via MCP - **Discover** — semantic and lexical search across the block catalog, browse trending blocks, fetch a specific block or its version history, find blocks compatible with one you're already using. - **Compose** — assemble a complete prompt from multiple blocks in one call. - **Contribute** — submit new blocks, fork existing ones into your own variant, r
