MCP Servers: Best Practices, Design Choices and Their Consequences
summary
The talk examines the Model Context Protocol (MCP) as the bridge between LLMs and the tools, APIs and data they use, and focuses on design trade-offs for running MCP servers: generic vs domain-specific servers, open vs controlled access, and flexibility vs security. Using real projects and deep demos, it analyzes how these choices affect developer experience, performance, token consumption and security, draws parallels with early REST API mistakes, and presents concrete best practices for production-ready, safer and more efficient MCP servers.
