metaphi

The Metaphi AI command line. Sign in, manage your organization's people and keys, and anonymize agent traces.

Install

brew install metaphi-labs/tap/metaphi    # macOS and Linux

No Homebrew? Download the binary for your platform from the latest release, unpack it and put metaphi on your PATH. Each release lists its checksums.txt.

Calling it from Python instead: pip install metaphi-ai gives you the same command and the library (see below).

Quickstart (2 minutes)

metaphi login                  # opens the browser; confirm the code you see in the terminal
metaphi keys create prod --save
metaphi anonymize trace.json   # writes trace.anonymized.json

metaphi login signs you in as yourself. metaphi keys create makes an organization key (mai_sk_...). The key is shown once, so store it as a secret. --save also keeps it on this machine: in the OS keychain when there is one (macOS Keychain, Windows Credential Locker, Secret Service on Linux), otherwise in the config file.

A key you already have is saved with metaphi login --with-api-key, which reads it from stdin (or prompts without echo), so it never lands in your shell history or the process list.

Use it from your servers

Every call that does work runs on an organization key, never on a person's sign-in:

export METAPHI_API_KEY=mai_sk_...
metaphi anonymize trace.json -o out.json --json

--json prints {"output"} on stdout, with progress on stderr. Or from Python:

from pathlib import Path
from metaphi.anonymize import anonymize

result = anonymize(Path("trace.json"), Path("out.json"), api_key="mai_sk_...")
result["output"]   # the path of the anonymized trace

One key per environment (prod, staging) or per customer is a good default. Revoking one stops only that key.

Anonymize options

The organization key comes from METAPHI_API_KEY, then the saved key. (--api-key still works but is deprecated: an argument is visible in shell history and to other processes.)

People, private organizations, accounts and secrets are always replaced, each with one consistent synthetic value of the same kind, and the trace keeps its structure. An adversarial pass then reads the output for anything still real.

Your organization

metaphi whoami
metaphi members list
metaphi members add dev@yourco.com --role admin   # admins manage keys and people; members don't
metaphi members remove dev@yourco.com
metaphi keys list
metaphi keys revoke key_0123abcd

If you manage more than one organization, name it with --org <id>.

Configuration

Sign out with metaphi logout. It ends this sign-in everywhere it is used.
