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 | $0.00019 | $0.00380 |
| Opus 5 | $0.00010 | $0.00190 |
| Sonnet 5 | $0.00004 | $0.00076 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
mcp-dev 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 5d 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.
What it actually says
MCP Dev - RoastPilot
Use this skill for local development setup and hardware-free validation. Root
AGENTS.md is the current gate authority.
The top-level parent alone performs venv/dependency installation, build, and clean-wheel smoke where network or dependency resolution is needed. Write-capable leaves return affected offline-gate evidence and never request network or sandbox relaxation.
Setup
python3.11 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -e . --group dev
Current Validation
python -m pytest --cov=coffee_roaster_mcp --cov-branch --cov-report=term-missing
python -m ruff check .
python -m ruff format --check .
python -m pyright
coffee-roaster-mcp --help
coffee-roaster-mcp --version
python -m build
python .github/scripts/smoke_install_built_wheel.py
Mock-Safe Bootstrap Smoke
For bootstrap work, confirm the default config still requires no roaster hardware, no microphone, and no model download from a guaranteed-empty temporary directory:
python -c "import os, tempfile; from coffee_roaster_mcp.config import load_config; tmp = tempfile.TemporaryDirectory(); os.chdir(tmp.name); c = load_config(environ={}); print(c.roaster.driver, c.first_crack.mode, c.first_crack.precision); tmp.cleanup()"
Expected output:
mock disabled int8
Notes
- All validation remains hardware-free unless a separate human-owned contract authorises otherwise.
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.

mcp-dev is a skill published in the GitHub repository syamaner/coffee-roaster-mcp (0 stars, last pushed 4d ago), licensed Apache-2.0. It adds 19 tokens to every session and 380 once invoked, about $0.0001 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.
Other skills, from other repositories
scrape-batch
Extract many known URLs in one polite, rate-limited pass. Use when the user hands over a list of links, a set of search hits to read in full, or asks to "scrape these pages" / "pull the content from all of them". Drives extract(action="batch"), which fans out with per-domain rate limiting and returns partial results…
compare
Structured comparison of 2+ alternatives with consistent criteria and decision matrix.
research-topic
Multi-step research orchestration. Use when user asks "research X", "summarize current state of Y", "what's the latest on Z", or compares approaches. Calls extract(action="agent") which searches the web, extracts top results, then synthesises a citation-preserving Markdown answer with one configured LLM.
knowledge-audit
Review and clean up stored memories — find duplicates, contradictions, stale entries, and consolidate.
temporal-query
Answer time-travel questions over stored memory — what was believed at a past point in time, when a belief changed, and what replaced it. Use when the user says "as of", "back in", "at the time", "history of", "timeline", "what did I think then", or asks why a current memory contradicts an older one.
memory-commit
Use when the user explicitly says "remember this", "save this", "ghi nho", "luu lai", "save for next time", or otherwise asks to persist the immediately preceding context. Captures with the appropriate contexttype (decision, preference, fact, skill, task, conversation) so future sessions can retrieve it accurately.
