FAQPage Schema
How do I build an MCP server that exposes safe tools to LLMs?

To build an MCP server, you define tool registration patterns using Python or TypeScript SDKs, ensuring tools are well-documented, consistently named, and secure for agent interaction.

What is the best way to structure an MCP server for multiple transports like stdio, SSE, and HTTP?

Structuring an MCP server for multiple transports involves using the Python or Node/TypeScript SDKs to implement multi-transport support, allowing scalable agent workflows across stdio, SSE, and HTTP.

How does MCP handle tool pagination, error handling, and security?

MCP enforces tool safety through best practices for pagination, error handling, and security, ensuring that server interactions with LLMs remain robust, auditable, and consistently managed.

Can I use TypeScript and Python SDKs to register tools in an MCP server?

Yes, you can use TypeScript and Python SDKs to register tools in an MCP server, providing consistent naming and safe, well-documented interfaces for LLM consumption.

How do I test and evaluate MCP server tooling for agent workflows?

Testing and evaluating MCP server tooling requires implementing comprehensive evaluation workflows and reusable utilities to ensure the exposed tools are robust and auditable for agent workflows.
