möbius Gateway

mobius-gateway is the headless möbius runtime. One process owns machine credentials, usage, and scheduled tasks while hosting up to 32 independent chat agents. Every chat owns its canonical workspace, model, reasoning, agent features, approval policy, and prompt. The terminal, iPhone, and iPad clients can independently open different chats or subscribe to the same one. Chats store enabled optional middleware IDs and generic scalar settings. The gateway advertises the ordered middleware catalog plus integer and select control schemas, so terminal and iOS clients render new middleware and settings without capability-specific code. New chats enable attachments, artifacts, context offloading, compaction, scratchpad, and subagents by default; tasks, workspace instructions, and extensions start disabled. Context offloading masks successful tool output after a 50,000-token trailing window. The gateway always installs sandboxing, workspace tools, turn steering, and durable sessions.

Install mobius-cli to get both the client and gateway commands:

cargo install --locked mobius-cli

mobius-gateway reset-default-agent stops the gateway and reapplies the shipped defaults for future chats while preserving providers, credentials, installed extensions, existing chats, and workspaces. Start the gateway again after the command completes.

The separately versioned mobius-gateway crate is the runtime library used by those binaries.

Initialize and pair the default gateway:

mobius-gateway init

Quick Connect is selected by default. It starts an account-free Cloudflare Quick Tunnel, captures its temporary trycloudflare.com address, and displays both the public wss:// endpoint and local tcp://127.0.0.1:8741 endpoint with one ten-minute, one-use pairing code. No Cloudflare account, domain, route, or connector token is required. The address changes whenever the gateway restarts, so use the advanced stable-hostname option for a durable endpoint. Once a client pairs through either endpoint, connect returns and the gateway keeps running in the background. Run mobius-gateway connect later to advertise a fresh code while the gateway remains running.

For that advanced option, enter the intended hostname and connector token. möbius starts the connector first and waits for pairing; you can then publish the hostname to http://127.0.0.1:8741 in Cloudflare without the missing-route failure aborting setup. möbius stores the token in an owner-only file outside gateway.toml and starts cloudflared with --token-file. The GitHub binary archives include a pinned cloudflared sidecar; source and cargo install builds require cloudflared beside mobius-gateway or on PATH. The gateway also prints a copyable mobius-pair:v1 setup code and, in an interactive terminal, an iPhone/iPad QR. Both contain only the public endpoint and short-lived möbius pairing code. They prefill the Apple pairing form for confirmation and never contain the Cloudflare token.

If the selected state directory already exists, interactive initialization asks for explicit confirmation before stopping the old gateway and deleting its configuration, chats, providers, and paired devices.

For non-interactive setup, keep the token in an owner-only file and use:

mobius-gateway init \
  --cloudflare-hostname mobius.example.com \
  --cloudflare-token-file /private/path/tunnel-token
mobius-gateway connect

Plaintext listeners and clients are restricted to loopback. An iPhone, iPad, or another machine therefore needs a routable TLS endpoint with a publicly trusted certificate whose hostname matches that endpoint:

mobius-gateway init --listen 0.0.0.0:8741 \
  --tls-cert /absolute/path/fullchain.pem \
  --tls-key /absolute/path/private-key.pem
mobius-gateway connect --endpoint tls://gateway.example:8741

On iPhone, iPad, or Mac, choose Add gateway and enter the displayed Gateway address and One-time code. On another terminal client, run the displayed mobius pair command. Pairing consumes the code and returns a unique bearer token; Apple clients keep it in Keychain and mobius keeps it in its owner-only gateway account file. Later connections use that token, not the one-time code.

To add another device while the gateway is already running, an authenticated Apple client can open Gateway → Pair another device → Create one-time code; an authenticated terminal client can run /pair. mobius-gateway connect is the host-side recovery flow for a stopped gateway.

By default, owner-only state is stored under ~/.mobius/gateway. Set MOBIUS_GATEWAY_STATE_DIR or pass --state-dir to use another location. On Linux, run the gateway account without permitted or ambient capabilities; Bubblewrap rejects a non-root caller that retains them. Hosts that allow user, PID, mount, and network namespaces but forbid mounting procfs inside a child PID namespace can set MOBIUS_GATEWAY_SANDBOX_PROC=empty. This keeps PID isolation and mounts an empty /proc; the default private mode mounts a private procfs. Provider credential APIs are write-only and never return stored secret values. Full-access shell commands can use the host filesystem and network while file tools remain workspace-scoped. Those shell commands can access gateway state, TLS credentials, stored provider credentials, and any other files or services available to the gateway account. The configured-model catalog and new-chat default live in gateway configuration. The first configured model becomes the default. A new chat copies that default, then stores its own selected model and runtime recipe beside its durable checkpoint; changing one chat never changes the catalog, another chat, or its workspace.

The gateway also owns the extension catalog. Clients may install a standalone Agent Skill or OpenAI plugin from a credential-free HTTPS Git source. Packages are stored as content-addressed snapshots and remain inactive until selected for the default agent or a chat. Executable plugin hooks require explicit review for the installed package digest. Update and uninstall require deactivation first; per-workspace plugin data under .mobius/extensions is retained.

Automation may register OpenRouter with a direct credential read from bounded standard input, keeping the key out of arguments and URLs:

printf %s "$OPENROUTER_API_KEY" | mobius-gateway register-provider \
  --provider openrouter --model MODEL \
  --reasoning-efforts medium,none,low,high,xhigh,max \
  --web-search live --credential-stdin

A trusted OpenRouter-compatible connector can instead remain credentialless:

mobius-gateway register-provider --provider openrouter --model MODEL \
  --reasoning-efforts medium,none,low,high,xhigh,max \
  --web-search live \
  --base-url https://connector.example/v1 --credentialless

The command authenticates over the running loopback gateway, is idempotent, and prints {"provider":"openrouter"} on success. Credentialless mode is rejected for the direct OpenRouter endpoint and for providers that do not advertise it. Replacing a registered provider also updates its new-chat default and durable chat selections before success. The command fails while a resident chat is busy, so automation can retry without retiring the previous endpoint prematurely.

On macOS or Linux, open the live dashboard or gracefully stop the configured gateway from another terminal:

mobius-gateway
mobius-gateway provider
mobius-gateway exit

The no-command form starts the gateway in the background when needed, then shows every paired device and chat with active entries first, plus configured providers, editable defaults, and usage. Use Tab plus the arrow, page, or mouse wheel controls to scroll device and chat history. In Devices, press u or Delete and confirm to unpair the selected device; the dashboard cannot unpair its own credential. Press p for provider setup, d for defaults, or q to leave without stopping the gateway. provider opens the same provider setup directly. These views use this machine's saved gateway pairing.

Exit verifies the gateway's locked process record before sending SIGINT and waits up to five seconds for shutdown. serve --background starts a detached process on macOS or Linux and returns only after that process owns the gateway process record. Foreground serve continues to run until interrupted. Use serve --background for ordinary restarts after at least one client is paired.

If every client token is lost, stop the gateway and run the supervised pairing flow again; existing paired clients remain valid:

mobius-gateway exit
mobius-gateway connect # add --endpoint tls://HOST:PORT for TLS

The internal scheduler accepts one-time, interval, and standard five-field cron schedules, optionally bounded by an end time. Authenticated frontends manage them directly through the gateway protocol; task text contains only executable instructions. Runs use hidden durable möbius sessions and never install system crontab entries or spawn a child CLI. Task files are owner-only under the gateway state directory. With no clients and no active scheduled tasks, the gateway exits after 72 hours. Stopping it manually also stops scheduled work; cron occurrences are not replayed after restart, and intervals catch up at most one overdue occurrence.
