What is mcp-incus-vm CLAUDE.md?

Repository instructions for an MCP server that controls QEMU virtual machines over SSH, including screen actions, screenshots, and project management. QEMU is software for running virtual computers.

Use them when developing, checking, or running the server, including its SSH operations, mouse and keyboard automation, screenshots, and display-scaling handling.

They explain the project structure, setup commands, connection settings, and rules needed to change or test the server safely.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00292	$0.00292
Opus 5	$0.00146	$0.00146
Sonnet 5	$0.00058	$0.00058
Haiku 4.5	$0.00029	$0.00029

Security

Grade A, and why

mcp-incus-vm 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 7d 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

MCP QEMU VM Control — FastMCP server for controlling QEMU VMs via SSH (xdotool, scrot, asyncssh). Single-file app in server.py.

Commands

uv venv && source .venv/bin/activate && uv pip install -r requirements.txt
python server.py                          # run server
uv run mcp dev server.py                  # MCP Inspector
uv run ruff check server.py               # lint
pytest test_ssh_tools.py                   # tests

Config

Env vars (or .env): VM_HOST, VM_USER, VM_PORT, VM_DISPLAY, VM_IDENTITY, VM_KNOWN_HOSTS, VM_CONNECT_TIMEOUT. See .env.example.

Architecture

server.py: Project class (folder structure), AppContext (SSH + project state + DisplayCalibration), lifespan() (connection lifecycle + display calibration), run_vm_cmd() (shell helper). Tools: project management, UI automation (xdotool), screenshots (scrot), SSH ops, advice system. DisplayCalibration auto-detects HiDPI/scaling mismatches at startup; coordinate tools scale transparently. All outputs go to data/projects/.

Rules

See .claude/rules/ for detailed rules on architecture, security, and conventions.

Changes

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.
