FAQPage Schema
How do I build an MCP server that securely integrates external APIs?

To build an MCP server that securely integrates external APIs, you need clear tool schemas using Zod or Pydantic, branded types, audit logging, and resilient patterns like retry logic and circuit breakers. This skill provides reference implementations for both Python FastMCP and Node/TypeScript MCP SDKs.

What design patterns should I use for scalable MCP tool development?

For scalable MCP tool development, you should use design patterns that include clear tool schemas, branded types, and resilient error handling. This skill covers production-ready patterns like retry mechanisms, circuit breakers, and observability to ensure your MCP servers handle real-world scenarios effectively.

Does this MCP builder work with both Python and TypeScript SDKs?

Yes, this MCP builder works with both Python FastMCP and Node/TypeScript MCP SDK projects. It provides reference implementations, patterns, and best practices tailored for both environments, covering tool design, workflow, and error handling in production-like scenarios.

How do I handle errors and ensure resilience in MCP server workflows?

To handle errors and ensure resilience in MCP server workflows, implement retry mechanisms, circuit breakers, and observability patterns. This skill guides you through production-ready error handling techniques, including audit logging and resilient design patterns for integrating external APIs and services.

What's the best way to design tool schemas for MCP servers?

The best way to design tool schemas for MCP servers is using Zod for TypeScript or Pydantic for Python. This skill requires clear tool schemas and branded types to ensure type safety and proper validation when building MCP servers that integrate external APIs and services.

Can I use this skill for multi-tenant MCP server implementations?

Yes, you can use this skill for multi-tenant MCP server implementations. It covers real-world use cases including external API integration, data normalization, and multi-tenant considerations, providing scalable tool design patterns and best practices for both Python and TypeScript implementations.
