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 | $0.00522 | $0.00522 |
| Opus 5 | $0.00261 | $0.00261 |
| Sonnet 5 | $0.00104 | $0.00104 |
| Haiku 4.5 | $0.00052 | $0.00052 |
Grade A, and why
printyourduck-mcp AGENTS.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 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.

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

Agent Guide
Use this file before changing the repo.
Product Boundary
- PrintYourDuck MCP submits generated or selected 3D print files for manual quote review.
- Price ranges and instant estimates are allowed future product work when explicitly scoped. Until that exists, do not claim instant pricing. Pricing experiments must stay clearly labeled as estimates/ranges, separate from checkout, and backed by tests and public docs.
- Do not build instant checkout or payment at upload.
- Do not claim local production, Canadian-made production, or guaranteed delivery dates.
- Do not expose supplier locations, fulfilment routes, carrier strategy, supplier costs, margin logic, private file references, customer data, or dashboard screenshots in public docs, tests, logs, issues, or examples.
- The package is preconfigured for
https://printyourduck.com.
Commands
pnpm check
pnpm check:security
pnpm check:release
Run pnpm check:release before release-readiness claims.
Repo Ownership
This repo owns the local stdio MCP helper, package metadata, MCP Registry metadata, container image target, and package release automation.
It does not own the PrintYourDuck website, admin UI, email/payment operations,
Vercel deployment, or hosted /api/mcp implementation.
Release Truth
Publish claims should match observed evidence in this repository and GitHub/Registry checks.
Do not hard-code a public artifact state without checking it live. The current
release target is the version in package.json; npm, GitHub release, GHCR, and
MCP Registry can each be ahead of or behind the local checkout.
Current server.json advertises the npm package only. Do not add the GHCR image
to registry metadata until anonymous docker manifest inspect works for the
target image version.
Before claiming registry/public-installation readiness, verify:
npm view @printyourduck/mcp version
gh release view mcp-v<version>
curl -f "https://registry.modelcontextprotocol.io/v0/servers/com.printyourduck%2Fquote/versions"
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.
