What is the Prompt MCP Server?

A framework for defining, managing, and applying prompt decorators to enhance interactions with LLMs

What you get

Prompt Decorators introduces a standardized annotation system inspired by software design patterns that allows users to modify LLM behavior through simple, composable "decorators." By prefixing prompts with annotations like +++Reasoning, +++StepByStep, or +++OutputFormat, users can consistently control how AI models process and respond to their requests across different platforms and implementations.

  • 📚 Registry-based decorator management — Centralized registry of decorators with metadata
  • ✅ Parameter validation and type checking — Robust validation of decorator parameters
  • 🔢 Decorator versioning — Support for semantic versioning of decorators
  • 🔄 Compatibility checking — Verification of decorator compatibility
  • 📝 Documentation generation — Automatic generation of documentation for decorators
  • 🧩 Dynamic loading — Runtime decorator loading from definition files
