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 | $0.00613 | $0.00613 |
| Opus 5.5 | $0.00245 | $0.00245 |
| Sonnet 5.5 | $0.00123 | $0.00123 |
| Haiku 4.5 | $0.00061 | $0.00061 |
Grade A, and why
MCP-Plugin-dotnet AGENTS.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 11d 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 — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
MCP Plugin for .NET — a SignalR bridge that lets heavy .NET apps (Unity, WPF, game servers) expose
MCP tools/prompts/resources to AI clients without being spawned as subprocesses. Three NuGet
packages: McpPlugin (client), McpPlugin.Server (bridge), McpPlugin.Common (shared).
Build / run
dotnet build McpPlugin.sln
dotnet test
cd DemoWebApp && dotnet run port=11111 client-transport=stdio
Critical invariants
- ALL
.csfiles must start with the ASCII art Apache 2.0 license header — copy from any existing file. - Namespaces are reverse-domain
com.IvanMurzak.McpPlugin.*— not standard C# convention. - Version is single-sourced in
McpPlugin/McpPlugin.csproj; usecommands/bump-version.ps1to change it. - Public API changes here cascade to Unity-MCP and downstream extensions — call them out to the owner in the PR.

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.
