install

An install or upgrade command for the m3-memory command-line tool and its system files. A command-line tool is a program operated from a terminal.

In plain words
What is it for?
Use it when m3-memory is missing or outdated, including when the normal command is not available on the system path.
Why use it?
It guides installation on macOS, Linux, or Windows and then explains how to verify that the updated tool works.

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.

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 C, and why

install scanned grade C 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 2d 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.

What it actually says

m3-memory install / upgrade

Step 1 — detect current state. Try in order:

mcp-memory --version                       # plain CLI
python -m m3_memory.cli --version           # module form (Windows --user)

Step 2 — branch on what step 1 printed.

Not installed (both commands fail):

  • On Linux / macOS, suggest:
    curl -fsSL https://raw.githubusercontent.com/skynetcmd/m3-memory/main/install.sh | bash
    
  • On Windows, suggest:
    pip install --user m3-memory
    # then add %APPDATA%\Python\Python<NN>\Scripts to user PATH if needed
    
    Link them to https://github.com/skynetcmd/m3-memory/blob/main/docs/install_windows.md for full instructions.

After install completes, tell the user to re-run /m3:health in a NEW Claude Code session (PATH changes don't apply to the current one).

Already installed (a version printed):

  • On Linux / macOS, run:
    pipx upgrade m3-memory
    mcp-memory update
    
  • On Windows, run:
    pip install --user --upgrade m3-memory
    python -m m3_memory.cli update
    
  • Then /m3:health to verify.

Step 3 — print one-line summary of what action was taken or recommended.

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.

install is a command published in the GitHub repository skynetcmd/m3-memory (22 stars, last pushed 3d ago), licensed Apache-2.0. It adds 14 tokens to every session and 326 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
