Unity MCP Efficient

A smaller tool interface with access to the full operation catalog

Facade design and implementation
01 / The challenge

The challenge

A large model-visible tool surface consumed context before an agent could choose the operation it needed.

02 / How I approached it

How I approached it

I separated discovery from execution, loading operation schemas on demand and bounding returned results. Batches, stored results, receipts and idempotent retries address repeated mutations, asynchronous work and Unity domain reloads.

System flow
  1. Discover

  2. Load schema

  3. Execute

  4. Inspect result

03 / The outcome

The outcome

The published author benchmark of 24 August 2026, against upstream v10.1.0, records 48 → 6 model-visible tools and access to 377 operations. Schema context falls from 23,280 to 915 estimated tokens (characters ÷ 4); this is a documented estimate, not an independently reproduced runtime or cost benchmark.
