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 | $0.03050 | $0.03050 |
| Opus 5.5 | $0.01220 | $0.01220 |
| Sonnet 5.5 | $0.00610 | $0.00610 |
| Haiku 4.5 | $0.00305 | $0.00305 |
Grade B, and why
Godot-MCP AGENTS.md scanned grade B with 2 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 yesterday.
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.

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

AGENTS.md — Godot-MCP
Godot-MCP connects LLM agents to the Godot editor over the Model Context Protocol — the Godot sibling of Unity-MCP. The MCP server is NOT in this repo: the addon consumes the shared GameDev-MCP-Server.
The addon is a [Tool] EditorPlugin (GodotMcpPlugin) that installs the main-thread dispatcher,
builds a Reflector with Godot type converters, and connects to an MCP server (cloud ai-game.dev by
default, or a custom local one) through the McpPlugin SignalR client. The editor tools' data layer is
RQL (rql-query / rql-mutate / rql-schema, Editor/Rql/). The MCP/reflection/query stack
(com.IvanMurzak.ReflectorNet, com.IvanMurzak.McpPlugin, com.IvanMurzak.Rql — PolyForm Shield 1.0.0) is
not forked: it is consumed from nuget.org as PackageReferences whose pins are owned by the upstream release
pipelines. Never bump them here. The current pins are in Godot-MCP.csproj (mirrored by Godot-MCP.Tests/,
Godot-Tests/ and cli/src/utils/addon-deps.ts; keep them in lockstep) and restated in README.md / docs/.

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.

Godot-MCP AGENTS.md is an instructions file published in the GitHub repository IvanMurzak/Godot-MCP (325 stars, last pushed yesterday), licensed Apache-2.0. It adds 3,050 tokens to every session, about $0.0122 per session on Opus 5.5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-12.
