Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.05269 | $0.05269 |
| Opus 5 | $0.02635 | $0.02635 |
| Sonnet 5 | $0.01054 | $0.01054 |
| Haiku 4.5 | $0.00527 | $0.00527 |
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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 314 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
MCP server enabling AI assistants to interact with Anki via AnkiConnect. Built with NestJS and @rekog/mcp-nest.
- Package:
@ankimcp/anki-mcp-server(npm) - License: MIT
- Status: Beta (0.x.x) - breaking changes allowed
- User-facing docs:
README.mdcovers installation, client setup (Claude Desktop/MCPB, HTTP, tunnel), and the full tool catalog — consult it for anything user-facing rather than reconstructing it here.
Quick Reference
# Build & Run
npm run build # Build → dist/ (all three entry points)
npm run start:dev:stdio # STDIO mode with watch
npm run start:dev:http # HTTP mode with watch
npm run start:dev:tunnel # Tunnel mode with watch + debug
# Testing
npm test # All tests
npm test -- path/to/file.spec.ts # Single test file
npm run test:tools # Tool unit tests only
npm run test:workflows # Multi-tool workflow scenarios (mocked)
npm run test:cov # With coverage (70% threshold)
npm run e2e:full:local # One-shot E2E: up → test → down
npm run smoke:pack # Pack + install from tarball (no lockfile), verify initialize/tools-list
# Quality
npm run lint && npm run type-check # Pre-push checks (also runs via Husky)
# Debugging
npm run inspector:stdio # MCP Inspector UI for testing tools
npm run inspector:stdio:debug # With debugger on port 9229
npm run inspector:http # Inspector against HTTP transport
Architecture
Entry Points
Three entry points compiled in a single build:
| Mode | Entry | Use Case | Logging |
|---|---|---|---|
| STDIO | dist/main-stdio.js |
Claude Desktop, MCP clients | stderr |
| HTTP | dist/main-http.js |
Web-based AI (ChatGPT, claude.ai) | stdout |
| Tunnel | dist/main-tunnel.js |
Remote access via WebSocket tunnel | stderr |
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.

anki-mcp-server CLAUDE.md is an instructions file published in the GitHub repository ankimcp/anki-mcp-server (469 stars, last pushed yesterday), licensed MIT. It adds 5,269 tokens to every session, about $0.0263 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 2026-08-30.
