Unity API FAQs

Question 1

What is Unity API?

Accepted Answer

Unity API is an MCP (Model Context Protocol) server designed to give AI agents instant, accurate Unity API documentation. It prevents common issues like hallucinated signatures, wrong namespaces, and deprecated API usage in game development workflows.

Question 2

Which Unity versions are supported?

Accepted Answer

It fully supports Unity 2022 LTS, Unity 2023, and Unity 6, providing separate, up-to-date databases for each version. It can also auto-detect your project's Unity version from environment variables or project path.

Question 3

How does Unity API prevent AI hallucinations?

Accepted Answer

Instead of guessing, AI agents use Unity API's specialized tools to query verified documentation databases directly. This ensures they always retrieve correct method signatures, namespaces, and deprecation warnings, significantly reducing token costs and improving accuracy by up to 11x.

Question 4

What kind of Unity API information can AI agents access?

Accepted Answer

AI agents can search for APIs by keyword, get precise method signatures (including overloads), resolve `using` directives for types, retrieve full class references, and check for API deprecation warnings.

Question 5

Does it cover third-party Unity assets or only official APIs?

Accepted Answer

It comprehensively covers all UnityEngine and UnityEditor modules, plus popular official packages like Input System and Addressables. It does NOT cover third-party assets such as DOTween, VContainer, or Newtonsoft.Json.
