Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00792 | $0.00792 |
| Opus 5 | $0.00396 | $0.00396 |
| Sonnet 5 | $0.00158 | $0.00158 |
| Haiku 4.5 | $0.00079 | $0.00079 |
Grade A, and why
GameDev-MCP-Server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 26 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
What this is
Engine-agnostic C# ASP.NET Core MCP server shared by the Unity-MCP, Godot-MCP and Unreal-MCP engine plugins. Thin host (src/Program.cs) over the NuGet packages com.IvanMurzak.McpPlugin.Server + com.IvanMurzak.ReflectorNet — ALL real server logic lives in those packages; this repo contains no engine-specific code. Distributed as standalone executables (gamedev-mcp-server-<rid>.zip), a Docker image (aigamedeveloper/mcp-server), and a global dotnet tool on NuGet (com.IvanMurzak.GameDev.MCP.Server, command gamedev-mcp-server).
NOT AI-Game-Dev-Server (the ai-game.dev cloud LLM/billing proxy) — this is the local MCP stdio/http proxy host shared by the engine plugins.
Build / run
dotnet build com.IvanMurzak.GameDev.MCP.Server.csproj
dotnet run --project com.IvanMurzak.GameDev.MCP.Server.csproj -- --client-transport stdio --port 8080
- All-platform self-contained publish:
./build/build-all.sh/./build/build-all.ps1(--no-zip/-NoZipfor CI signing flows). The scripts live inbuild/and anchorpublish/to the repo root, so they work from any cwd. - Local cross-project dev against MCP-Plugin-dotnet/ReflectorNet source (sibling checkouts):
dotnet build -p:UseLocalMcpPlugin=true.
Versioning / releases
<Version>in the csproj +server.jsonmove together. Keep the McpPlugin.Server / ReflectorNet pins in lockstep with the engine plugins (see the Compatibility table in README.md).- NuGet readme is
docs/NUGET.md, NOT the root README. The rootREADME.mdis GitHub-flavoured HTML (centered divs, raw<img>banners, logo rows) that NuGet's markdown sanitizer mangles into run-together text; the csproj packs the plain-markdowndocs/NUGET.mdasREADME.md. Keep its versions/compatibility table in sync with the root README on each release. (NuGet bakes the readme into the published.nupkg— a readme fix only shows on nuget.org once a new version is published.) .github/workflows/deploy_server_executables.yml(release-published trigger) builds, code-signs (Azure Trusted Signing on Windows, codesign+notarytool on macOS — gracefully degrading when secrets are absent) and uploads the 7 zips..github/workflows/deploy_docker.ymlpushesaigamedeveloper/mcp-server:<version>+:latest(secretsDOCKERHUB_USERNAME/DOCKERHUB_TOKEN)..github/workflows/deploy_nuget.yml(release-published trigger) packs the global dotnet tool and pushescom.IvanMurzak.GameDev.MCP.Serverto NuGet via Trusted Publishing (OIDC,NuGet/login@v1asIvanMurzak— no stored API key). All three deploy workflows fire on the same published release, so the NuGet tool, Docker image, and zips ship together. One-time setup: the package id (or itscom.IvanMurzak.*reserved prefix) needs a NuGet.org Trusted Publishing policy bound toIvanMurzak/GameDev-MCP-Serverbefore the first release, exactly as the sibling library repos have.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
