The challenges of building an MCP server

This talk shares the real-world challenges encountered when building an MCP server for a production API with extensive surface area:

• The scaling problem: How do teams maintain dozens or hundreds of tool definitions without losing their minds?
• The consistency trap: Keeping tool schemas in sync with the actual API as it evolves.

It shows how these challenges were addressed by building a dynamic server that automatically generates tools from an OpenAPI specification. This approach transformed the server from a maintenance burden into a self-updating interface that stays in sync with the API.
