What is LocalHands CLAUDE.md?

Repository instructions for LocalHands, a local MCP server that lets a remote AI agent drive a workstation through 23 tools. The instructions cover its purpose, commands, architecture, request flow, and tests.

Installing the development environment, running tests, checking configuration, starting the server, and running lint checks.

They give the coding agent the project-specific commands and structure needed to change and test the server correctly.

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

LocalHands CLAUDE.md scanned grade A 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 2mo 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.

The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

LocalHands is a local MCP server: a cloud agent (Feishu Aily / Kimi K3 / any MCP client) connects over a tunnel and drives this workstation through 23 tools. The reasoning is remote; this process is the hands. Read README.md for the product-level rationale — this file covers what you need to change the code.

Commands

The project virtualenv holds the pinned mcp 2.x; a bare python may have the wrong one.

.venv\Scripts\python.exe -m pip install -e ".[dev]"

.venv\Scripts\python.exe -m pytest tests/ -q                      # 222 tests, no daemon/network/tunnel
.venv\Scripts\python.exe -m pytest tests/test_tools.py::TestEditFile -q          # one class
.venv\Scripts\python.exe -m pytest tests/test_tools.py -k "encrypted" -q         # by name

.venv\Scripts\python.exe -m localhands --config config.yaml --check   # validate config, don't serve
.venv\Scripts\python.exe -m localhands --config config.yaml           # serve (+ tunnel if enabled)
.venv\Scripts\python.exe -m localhands --config config.yaml --no-tunnel -v

ruff check .        # config lives in pyproject.toml; ruff is not a declared dev dep

scripts\restart.ps1 kills whatever holds the port, sweeps orphaned ngrok/cloudflared, relaunches detached, then polls /health until it answers before reporting success. Use it rather than restarting by hand — it is the only path that verifies the daemon actually serves. Status and log tails land in var/logs/restart.txt.

config.yaml is gitignored (it carries the auth token and machine paths); config.example.yaml is the documented template and the file to update when adding a config key.

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.
