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 | $0.00344 | $0.00344 |
| Opus 5 | $0.00172 | $0.00172 |
| Sonnet 5 | $0.00069 | $0.00069 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
anki-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
MCP server for Anki flashcard management via AnkiConnect. Single-file TypeScript project using @modelcontextprotocol/sdk.
Commands
pnpm install # Install dependencies
pnpm build # Compile TypeScript to dist/
pnpm watch # Auto-rebuild on changes
pnpm dev # Run directly with tsx (no build needed)
Architecture
Single source file (src/index.ts) containing:
ankiRequest<T>()- Generic HTTP wrapper for AnkiConnect API calls- Tool registrations:
get_decks,list_cards,create_cards,update_card,delete_cards,create_deck,delete_deck,rename_deck - Stdio transport for MCP communication
AnkiConnect endpoint: http://127.0.0.1:8765
Tool Pattern
Each tool follows:
server.registerTool("tool_name", {
title, description, inputSchema
// outputSchema omitted to keep tools/list small (Claude Desktop can drop large lists)
}, async (params) => {
// Return { content, structuredContent } or { content, isError: true }
})
Publishing
pnpm version patch # or minor, major
git push && git push --tags
gh release create v$(node -p "require('./package.json').version") --generate-notes
GitHub Actions auto-publishes to npm via OIDC trusted publishing.
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.
