AI tool catalogs must be treated as versioned APIs to prevent subtle client failures

By PulseAugur Editorial · [1 sources] ·

Developers building tools for language models need to treat their tool catalogs as public APIs with strict versioning to avoid breaking client applications. Unlike traditional HTTP APIs that return errors for changes, language models adapt to tool catalog modifications, leading to subtle and difficult-to-debug failures. To prevent this, tool names should be permanent, changes should be additive only (e.g., new optional parameters), and removed tools should fail loudly with clear instructions on alternatives. Clients should also read the current state of tools immediately before executing an action to prevent overwriting human changes. AI

IMPACT Highlights the need for robust API contracts for AI tools, impacting how developers build and integrate AI agents.

    tools/list is an API contract, and you are versioning it by accident

    <p>If you run an MCP server, your tool catalog is a public API. I do not think most of us are treating it like one.</p> <p>Here is the shape of the problem. A client connects, calls <code>tools/list</code>, gets your catalog, and starts using it. Then you rename a tool for clarit…
