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 | $0.00466 | $0.00466 |
| Opus 5 | $0.00233 | $0.00233 |
| Sonnet 5 | $0.00093 | $0.00093 |
| Haiku 4.5 | $0.00047 | $0.00047 |
Grade A, and why
ufo-mcp-server CLAUDE.md scanned grade A with 1 finding 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 8d 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.

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

🔰 Objective
Build a production-ready Go MCP server (ufo-mcp-go) that:
- Exposes the 12 capabilities defined in MCP_UFO_PLAN.md
- Persists user-defined effects in
/data/effects.json - Maintains in-memory shadow LED state and exposes
getLedState+ring_updateevents - Ships as a static Docker image (< 20 MB)
📐 Design Guard-Rails
- ≤ 20 tools.
- Rich NL descriptions & examples for every tool.
playEffect&stopEffectsmust stream progress.- Protect shared state with
sync.RWMutex(race-free). - Validate all inputs, surface MCP errors on timeouts.
🛠 Coding Checklist
-
go mod init github.com/starspace46/ufo-mcp-go -
internal/device(HTTP wrapper, retries) -
internal/effects(load/save/CRUD, mutex) - NEW
internal/state(LedState struct,Update,Snapshot, event emit) - Event bus & SSE fan-out
- Register tools/resources (
sendRawApi,getLedState, etc.) - Unit tests: CRUD, ring pattern, state updates, SSE
-
make dockerbuilds image
🧪 Testing
- Use
httptest+UFO_IP=http://localhost:8000for device calls - Cover
getLedStatecorrectness andring_updateemission - Integration test: run server, subscribe SSE, call
setRingPattern, assertring_update
✔️ Definition of Done
- All checklist boxes ticked (including shadow-state tasks)
go test ./... -racepassescurl …/getLedStatereturns expected JSON after any mutating tool- SSE subscriber receives

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.

ufo-mcp-server CLAUDE.md is an instructions file published in the GitHub repository rhoegg/ufo-mcp-server (1 stars, last pushed 1y ago), licensed Apache-2.0. It adds 466 tokens to every session, about $0.0023 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).
