FAQPage Schema

How do I build an MCP server with TypeScript or Python?▼

Building an MCP server involves using the TypeScript MCP SDK or Python FastMCP to register tools with typed validation. This approach enforces standards-aligned project layouts and safe transport options for local and remote deployments.

What is the best way to validate MCP tool inputs?▼

The best way to validate MCP tool inputs is by using Zod for TypeScript or Pydantic for Python. These libraries enforce strict input validation and descriptive annotations, ensuring safety and correctness before production deployment.

Can I expose MCP tools over streamable HTTP transports?▼

Yes, you can expose MCP tools over streamable HTTP transports. The MCP SDK supports both stdio for local usage and streamable HTTP for remote deployments, enabling flexible API integrations and data retrieval.

Does the MCP SDK support both local and remote server deployments?▼

Yes, the MCP SDK supports both local and remote deployments. By utilizing stdio and streamable HTTP transports, developers can expose tools, resources, and prompts across different environments while maintaining strict input validation.

How to test an MCP server before production deployment?▼

To test an MCP server before production, you should follow a structured evaluation-ready workflow and quality checklist. This ensures security, correctness, and maintainability by validating tool registration and transport configurations.
