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 | $0.01727 | $0.01727 |
| Opus 5 | $0.00864 | $0.00864 |
| Sonnet 5 | $0.00345 | $0.00345 |
| Haiku 4.5 | $0.00173 | $0.00173 |
Grade A, and why
unreal-mcp-additional-tools 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What This Is
An MCP (Model Context Protocol) server for Unreal Engine — 81 tools across 14 subsystems. TypeScript/Node.js, ESM, communicates with UE via four transport layers.
The toolset is deliberately deduplicated against Epic's official Unreal MCP server so both can be connected at once. The blueprint (12 tools) and plugin (3 tools) modules were removed outright as strict subsets of Epic's BlueprintTools/PluginToolset; actor, asset, and material were trimmed to only what Epic lacks. When adding tools, check Epic's server first — don't reintroduce overlap. See README for the full dedupe rationale.
Commands
npm run dev # Watch-mode dev server (tsx)
npm run build # Compile TypeScript → dist/
npm start # Run compiled server
npm test # vitest in watch mode; `npm test -- run` for a single non-interactive pass
npm run lint # Biome check src/
npm run fmt # Biome format --write src/
Architecture
stdio (MCP protocol)
→ bin.ts # CLI entry, creates server + StdioTransport
→ index.ts # createServer() factory, registers tools & resources
→ ConnectionManager # Orchestrates all 4 transports
→ 14 Tool Modules # Each exports register*Tools(server, manager, config)
→ 4 Transports → Unreal Engine
Transports (src/transports/)
| Transport | Protocol | Port | Requires |
|---|---|---|---|
| RemoteControlClient | HTTP to UE Remote Control API | 30010 | Remote Control API plugin (built-in) |
| PythonExecClient | UDP multicast discovery + inverted TCP | 6776 | Python Editor Script Plugin w/ Remote Execution |
| PluginBridgeClient | TCP, length-prefixed JSON | 55557 | Optional C++ plugin for deep Blueprint/K2 access — not used by any tool today, see Plugin Enhancement Layer below |
| SubprocessRunner | Spawns UAT/UBT processes | N/A | Engine path only (no editor needed) |
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.

unreal-mcp-additional-tools CLAUDE.md is an instructions file published in the GitHub repository nodormu/unreal-mcp-additional-tools (0 stars, last pushed 13d ago), licensed MIT. It adds 1,727 tokens to every session, about $0.0086 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
