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 | $0.02492 | $0.02492 |
| Opus 5 | $0.01246 | $0.01246 |
| Sonnet 5 | $0.00498 | $0.00498 |
| Haiku 4.5 | $0.00249 | $0.00249 |
Grade D, and why
tmw-mcp CLAUDE.md scanned grade D with 2 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 6d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- **Credentials.** `credentials.json` is `chmod 600` (owner read/write only) and gitignored. Never log it or commit it. Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this is
A Python client for The Mana World (a tmwAthena-based MMORPG) that exposes the game as an MCP server. The intended consumer is an AI agent (Claude Code), but a human-driven CLI (tmw_mcp/main.py) and a legacy file-driven bot (tmw_mcp/bot.py) share the same game-client core.
All runtime code lives in the tmw_mcp/ package. The only third-party dependency is mcp. Everything else is stdlib.
Commands
# Setup
python3 -m venv .venv
.venv/bin/pip install -e .
# Run the whole suite (from repo root; loads tests/__init__.py which
# redirects XDG_STATE_HOME and XDG_CACHE_HOME to tempdirs so tests
# don't pollute your real ~/.local/state/tmw-mcp).
.venv/bin/python -m unittest discover
# Run a single test (still from repo root)
.venv/bin/python -m unittest tests.test_dashboard
.venv/bin/python -m unittest tests.test_shim_proxy
.venv/bin/python -m unittest tests.test_follow
.venv/bin/python -m unittest tests.test_ranged_combat
.venv/bin/python -m unittest tests.test_resources
.venv/bin/python -m unittest tests.test_credentials
# Console scripts (created by ``pip install -e .``)
tmw-mcp # stdio MCP entry point (with self-restart shim)
tmw-mcp-server [--shim] [--dashboard-port N] # daemon directly (advanced)
tmw-mcp-cli --credentials credentials.json # interactive human REPL
tmw-mcp-register --user USERNAME --char-name CHARNAME
# Module form (works without installing)
.venv/bin/python -m tmw_mcp.mcp_shim
.venv/bin/python -m tmw_mcp.mcp_server [--shim]
.venv/bin/python -m tmw_mcp.main --credentials credentials.json
.venv/bin/python -m tmw_mcp.register --user USERNAME --char-name CHARNAME
# Regenerate PACKET_SIZES from upstream tmwa (dev tool)
python3 scripts/extract_packets.py # prints a dict; paste over PACKET_SIZES in tmw_mcp/packets.py
No linter or formatter is wired up. Tests insert the repo root onto sys.path themselves so they run from any cwd.
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.

tmw-mcp CLAUDE.md is an instructions file published in the GitHub repository bjorn/tmw-mcp (0 stars, last pushed 10d ago), licensed MIT. It adds 2,492 tokens to every session, about $0.0125 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
