SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

MCP pattern guidelines to standardize MCP server tooling, including schemas, logging, error handling, and response formatting across projects.

Core Features & Use Cases

  • Always import schemas from @youdotcom-oss/api to avoid duplicating schemas and ensure consistent validation.
  • Enforce standardized tool response formats with content and structuredContent to align with MCP protocol.
  • Promote safe error handling by returning errors via structured responses rather than throwing exceptions, and provide clear logging through the MCP protocol.
  • Testing guidance and pattern references to ensure codebase consistency across MCP tools.

Quick Start

Install and run the shared MCP patterns in your local environment to validate adherence and usage.
