About the project

Mooncake is a serving platform for Kimi, an LLM service from Moonshot AI, built around sharing and transferring the KV cache used during language-model inference. It supports disaggregated serving and data movement between inference, training, and rollout systems. The catalogue add-ons operate or integrate with Mooncake-based serving and transfer workflows.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

Mooncake AGENTS.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 1mo 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.

Pull Request Guidelines

  • Follow CONTRIBUTING.md for PR title prefixes, RFC expectations, and contribution workflow.
  • Before opening a PR for nontrivial work, check whether an existing issue or open PR already covers the same change. If the work overlaps, explain the difference instead of duplicating it.
  • Do not open low-value busywork PRs for isolated typo, style, or mechanical changes unless they are part of a substantive requested change.
  • Use .github/pull_request_template.md when preparing a PR, and fill in the relevant sections for description, module, type of change, testing, checklist, and AI assistance disclosure.
  • For AI-assisted changes, make sure the human submitter has reviewed every changed line and can defend the change end-to-end.
  • Before handoff, run pre-commit on the files touched by the change when the toolchain is available (see CONTRIBUTING.md for the PR-scoped pre-commit run --files ... command). Do not use pre-commit run --all-files for routine PRs; if it rewrites unrelated files, leave those edits out of the PR.
  • Keep PRs lean: review git diff before staging, and include only changes required for the requested task.

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.
