AkerMCP v1.4.0

AkerMCP v1.4.0 - AI-authored 2D placeholders + scene authoring

?? Plugin redeploy required: the IPC protocol moved to 1.5.0. Update the engine
plugin (Unity package / Godot addon / Stride adapter) along with the server.

Highlights

• create_sprite - AI-authored 2D vector placeholders, rasterized server-side.
  The AI emits a flat-geometric shape-spec (JSON: ellipses, rects, polygons, lines,
  SVG-subset paths, gradients); the server rasterizes it to an RGBA PNG (pure-managed
  ImageSharp.Drawing) and imports it as a real sprite. Engine-agnostic - the engine
  receives a ready raster, so it works regardless of its own vector support. Unity & Godot
  import + place the sprite; Stride persists a real .sdtex texture asset (verified
  live in Game Studio).

• End-to-end scene authoring. new_scene / open_scene / save_scene (Unity, Godot,
  Stride) and write_script (writes a source file into the project, resolved engine-side)
  let an AI build a 2D prototype - art, scene and gameplay code - from a single prompt.

• focus_window. Bring any window on the machine to the foreground (restoring it if
  minimized), matched by a title substring.

• More reliable screenshots. take_screenshot now falls back to OS-level window
  capture on any internal capture failure (not only NOT_SUPPORTED), making it robust on
  Stride, whose embedded editor game only renders on demand.

Other changes

• IPC protocol 1.5.0 (adds the IpcRequest.Binary inbound channel + the new methods).
• New optional adapter capabilities: ISpriteImporter, ISceneManager.
• Hardening: rasterizer guards against OOM on large targets and tolerates float dimensions.
• README refreshed; full feature parity continues across Unity, Godot, and Stride.

See the Quick Start for setup instructions.

• feat: scene-view gizmo capture + execute globals/using fixes

See the Quick Start for setup instructions.

AkerMCP v1.1.0

AkerMCP v1.1.0 - Godot support

AkerMCP now speaks Godot 4.x in addition to Unity. The same 14 reflection-based MCP tools (inspect, set_property, execute, take_screenshot, ...) now work inside the Godot editor through a dedicated adapter - no server changes, no per-engine tool definitions.

New: Godot 4.x (.NET/C#) adapter

• Full parity with the Unity adapter: scene-graph traversal, property/method reflection, node create/delete, query, selection, editor context, Roslyn execute, and editor-viewport screenshots.
• Drop-in addon: download AkerMcp.Godot-addon.zip, extract into your project's addons/, add the AkerMcp core via NuGet/ProjectReference (see README), then enable the plugin.
• Godot specifics handled automatically: single-thread main-loop dispatch, case-insensitive property paths (position.x -> Position.X), value-type converters (Vector3, Color, Rect2, Aabb, ...), and dotnet build compile diagnostics.

Repository restructure

• Engine adapters are now standalone plugins under plugins/unity/ and plugins/godot/, with thin sample projects under samples/ that link them via a junction (setup-samples script). One canonical copy per adapter - no more plugin buried inside a host project.

Release artifacts (now 5)

• AkerMCP.unitypackage - Unity plugin
• AkerMcp.Godot-addon.zip - Godot addon (new)
• AkerMcp.Server-win-x64.zip, AkerMcp.Server-osx-x64.zip, AkerMcp.Server-linux-x64.zip - standalone MCP server

Upgrading

• Unity users: no action required - the Unity plugin is functionally unchanged. Re-import the new .unitypackage only if you want to stay current.
• Godot users: grab AkerMcp.Godot-addon.zip and follow the Godot setup in the README.

Full changelog: v1.0.0...v1.1.0

AkerMCP v1.0.0

First versioned release. Binaries are now distributed here instead of the repository tree.

Assets

• AkerMCP.unitypackage - Unity plugin (import into your project, includes all dependencies and Roslyn compilers)
• AkerMcp.Server-win-x64.zip / -osx-x64.zip / -linux-x64.zip - standalone self-contained MCP server, no .NET SDK required

See the Quick Start for setup instructions.

Highlights since the last package

• Multi-client named pipe: several MCP servers (e.g. Claude Code + a second client) can connect to the same Unity editor simultaneously
• Long-running tool calls (execute with high timeout_ms) no longer dropped by the heartbeat
• refresh_scripts survives the Unity domain reload and reports the compile result reliably
• delete honors recursive:false by re-parenting children
• execute captures Debug.Log output into the result
• JSON-RPC protocol compliance fixes (MethodNotFound, protocol version negotiation)
