MCP converters need curation, not coverage

A Reddit post argues that naive OpenAPI-to-MCP generators produce technically valid but practically unusable tool servers because they expose too many operations, bloated parameter schemas, and weak descriptions. The author says useful MCP servers require filtering, renaming, rewriting, and live API testing before agents can reliably use them.

// ANALYSIS

This is the right critique of the current MCP tooling rush: schema conversion is a compiler problem, but agent usability is a product design problem.

–Full API coverage sounds powerful until the agent has to choose between hundreds of near-duplicate tools with weak descriptions
–Parameter trimming matters because LLMs optimize from tool names, descriptions, and schema shape, not from human-facing API docs
–Swagger 2.0 support, circular refs, obscure OAS formats, and real auth behavior make "just parse the spec" much messier than demos suggest
–The winning OpenAPI-to-MCP products will look more like curated integration platforms than generic one-shot generators
