Aletheia

Aletheia CLI reference: every aletheia command and flag

Aletheia (aletheia-mem) ships a command line named aletheia that reads and writes the local hub directly. Every command works without the server running. This page lists each command with its flags, what it does and an example.

How to read this page

Entry points and basics

The package aletheia-mem declares four command names in its package.json: aletheia, aletheia-mem (the same file as aletheia), aletheia-server and aletheia-mcp. All four run on Bun. From a source checkout run bun bin/aletheia.mjs <command>.

Sync and remote MCP

These commands use the sync hub. See Sync and Remote MCP.

$ aletheia sync pair
Pairing code: d4543b23
Join on a device: aletheia sync join http://127.0.0.1:37791 d4543b23
$ aletheia mcp-link create --projects shop
{ "id": 1, "scope": "mcp", "projects": ["shop"], "url": "http://127.0.0.1:37791/mcp", "token": "...", ... }
$ aletheia sync push
No sync hub configured. Run: aletheia sync join <url> <code>

Team

Team commands act as the local operator, or as a member with --token-id. See Team mode.

$ aletheia team create platform
{ "id": 1, "name": "platform", "role": "owner", "projects": [], "members": 1, ... }
$ aletheia team decision platform "Use cents for money" --project shop
$ aletheia team brief platform --project shop

Service

aletheia service install|uninstall|status [--write] [--cpu-quota X] [--memory-max Y] writes a systemd user unit on Linux or a launchd plist on macOS. It is a dry run unless --write. It only writes the file; it never calls systemctl or launchctl. Windows is not supported. See Run as a service.

$ aletheia service status
{ "platform": "linux", "supported": true, "kind": "systemd", "label": "aletheia.service", "installed": false, ... }
