machine-mcp AGENTS.md

machine-mcp AGENTS.md is an instructions file for Codex, OpenCode from AndreaGriffiths11/machine-mcp. It costs 531 tokens per session, scanned A, original, MIT.

A set of instructions for using machine-mcp, a server that lets an agent work with files and commands on the user's laptop. It provides tools for checking the machine, running commands, reading and writing files, and recording terminal activity.

In plain words
What is it for?
Use it when working through machine-mcp to check the environment, run Copilot, Git, FFmpeg, or compiler commands, and manage files in its permitted workspace.
Why use it?
It gives the agent the machine-specific rules and workspace limits it needs to use these tools safely and correctly.

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.

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

machine-mcp AGENTS.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 4d 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.

Agent notes for machine-mcp

You are using the human's laptop through this MCP server. stdio means you are already inside their process. Do not invent a pairing step. Do not ask them to log into GitHub, Copilot, or Cursor through these tools.

What this is

Laptop-side tools: status, run, record_terminal, write_file, read_file. Workspace root is MACHINE_MCP_WORKSPACE or ~/machine-mcp-workspace. File tools cannot leave that root.

This does not replace Grok Bot Computers or Local execution. Those are a different control path. This server is the tool process on the machine they already use.

How to use the tools

  1. Call status first. Note OS, cwd, workspace, and whether copilot, ffmpeg, and git are on PATH.
  2. Put demo scripts and output files in the workspace with write_file / read_file. Relative paths only.
  3. Use run for commands that should execute in the workspace (copilot, git, ffmpeg, compilers). Pass a real argv string. Timeouts cap at 120 seconds.
  4. record_terminal will not produce a video. On Linux, install ffmpeg if needed and run its suggested command yourself via run. Other platforms return an unsupported-platform error. Do not fake a recording.

Never

  • Never read SSH keys, Copilot config dirs, .env files, credential files, cookies, or token stores.
  • Never run copilot login, gh auth login, or any login/device-code flow. Copilot CLI on this machine is already signed in. Use it.
  • Never print, log, or echo secrets. run redacts github_pat_ and AWS key shapes if they leak into stdout. Do not try to bypass that.
  • Never pass parent-directory segments or absolute paths to write_file / read_file.
  • Never start an HTTP listener or bind a port. v1 is stdio only.
  • Never git push or force-push unless the human explicitly asked in this turn.

Copilot CLI demos

Record or script Copilot CLI demos on this machine because it is already signed in. Prefer run with copilot on PATH. Keep demo artifacts inside the workspace. If you need a screen capture, use the ffmpeg command from record_terminal on Linux. Do not pretend a file exists if you did not capture one.

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.
