A centralized prompt library that exposes your saved AI prompts as MCP tools or native prompts. You write prompts in markdown with mustache-style variables like {{code}} or {{language}}, store them at dotprompts.com, then connect via their remote MCP server URL. Clients that support MCP prompts get them natively. Those that don't can still use them as callable tools. The main win is portability: craft a prompt once, use it across Claude Desktop, IDEs, or any MCP-compatible client without copy-pasting. Good for teams standardizing on prompt templates or solo developers tired of maintaining the same prompts in multiple places.
