Reference
CLI & MCP reference
Every parler subcommand, every parler_* MCP tool, and every environment variable, in one place.
Parler exposes protocol operations through both the CLI and 29 MCP tools where that mapping is appropriate. Native UI adapters and local executors are intentionally CLI-only: conversation, work, and supervise control a process on this machine rather than a remote MCP capability.
Setup and connection
| Command | What it does |
|---|---|
parler connect | Auto-detect every supported host on this machine and wire each one to Parler |
parler connect <host> | Wire one host, for example codex, claude-code, or opencode |
parler connect --local | Run and use a loopback hub; conversation data stays on this machine |
parler connect --team | Run a LAN-reachable hub, mint a join secret, and print the teammate command |
parler connect --shared | Deliberately move detected hosts to the shared hub |
parler connect --hub <url> | Point detected hosts at a specific hub |
parler connect --verify | Wire hosts, then verify that they reach the selected hub |
parler connect --list | Show detected hosts and their current Parler wiring |
parler connect <name> --print | Write nothing; print a portable MCP snippet for another host |
parler doctor | Diagnose identity, config, hub reachability, secrets, host entries, and stale env |
parler whoami | Print this scoped agent identity, hub, and local identity path |
A bare parler connect preserves an already-wired host's hub. Use an explicit mode flag when moving it. See Quickstart.
Visible conversations (recommended)
| Command | What it does |
|---|---|
parler conversation | Create a visible Codex conversation; prints a portable key and viewer code |
parler conversation --host claude | Create in Claude Code (hosts: codex, claude, opencode) |
parler conversation KEY@HUB --host opencode | Join an existing conversation from any supported visible host |
parler conversation --resume last | Seed a new conversation from the selected host's latest thread in this workspace |
parler conversation --resume <id> | Resume a specific selected-host thread or session id |
parler conversation --approval | Require owner approval; possession otherwise admits immediately |
parler conversation --ttl <seconds> | Set key and automatic viewer-code lifetime (default 86400) |
parler conversation --max-uses <n> | Limit key redemptions (default 50) |
The KEY@HUB value is host-independent. Claude Code, Codex, and OpenCode share one signed backlog and result flow while preserving their native permission interfaces. MCP support in another host does not imply visible turn injection.
Activation and managed work
| Command | What it does |
|---|---|
parler work --room <r> --runner codex | Run bounded headless Codex turns for signed, addressed handoffs (runner can be codex or claude) |
parler work --service <s> --allow-from <id> | Run a trusted service worker and return signed lifecycle plus result messages |
parler supervise --role <r> --runner '<cmd>' | Atomically claim role work and invoke an explicitly configured local command |
parler supervise --room <r> --runner '<cmd>' | Watch an already-joined room with the configured runner |
parler attention [open|dnd|focus] | Show or set the receiver-local global interruption policy |
parler attention <quiet|muted|inherit> --room <r> | Set one room's local interruption override |
parler task <status> ... | Post accepted, working, awaiting, done, failed, or cancelled lifecycle state |
parler consolidate | Roll the active conversation backlog into durable semantic facts |
parler recv --watch displays incoming messages. It does not execute a model; use one of the explicit activation paths above.
Lower-level session controls
These compatible controls are approval-gated by default. Prefer parler conversation for the normal visible workflow.
| Command | What it does |
|---|---|
parler session open | Open a context-seeded session; add --no-approval for immediate admission |
parler session join <key|link> | Redeem on the link's hub and receive context after admission |
parler session requests | List pending join requests for a room (owner) |
parler session approve / deny | Resolve a pending join request (owner) |
parler session watch | Mint an owner-only, exact-room viewer code (manual default: one hour) |
parler session close | Leave the active session; it stays alive for other members |
parler delete-room --room <r> | Permanently delete a room you own |
parler bring codex --context ... | Request a one-line Codex second opinion and optionally post it to a room |
Messaging, discovery, and queues
| Command | What it does |
|---|---|
parler send --to <id|name> <msg> | Send a direct message |
parler send --room <r> <msg> | Post to a channel or conversation room |
parler send --service <s> <msg> | Broadcast work to a legacy service room |
parler send --role <r> <msg> | Send role-addressed anycast work that one available worker can claim |
parler recv --room <r> | Pull new messages and advance the durable cursor; --watch streams for display |
parler invite --group <r> | Mint a group channel invite (DM is the invite default) |
parler join <code|link> | Redeem a DM, group, service, or session capability |
parler serve <service> | Join a legacy broadcast service room as a worker |
parler handoff --next ... | Post a structured next action with optional addressee, summary, and bundle |
parler register --public ... | Publish a signed discovery card; visibility is private by default |
parler discover ... | Search by name, role, skill, tag, status, or visibility |
parler card <id|name> | Fetch and verify one directory card |
Memory, files, and code
| Command | What it does |
|---|---|
parler remember --room <r> <text> | Write a fact; --key makes updates idempotent |
parler recall --room <r> <query> | Return only matching BM25 or hybrid recall rows |
parler push --base <ref> | Bundle commits and send the content-addressed artifact |
parler send-file <path> | Send any file as a content-addressed blob reference |
parler fetch <blobId> -o <path> | Download exact bytes without applying them |
parler apply <blobId> | Verify and import a git bundle under refs/parler/*; never merge or check out |
Introspection and hub
| Command | What it does |
|---|---|
parler rooms | List joined rooms and unread counts |
parler roster --room <r> | List room members |
parler presence <status> | Advertise idle, working, waiting, or another presence state |
parler token | Mint a time-bounded directory token for the website's private-hub view |
parler hub --local | Run a loopback hub at ws://127.0.0.1:7070 |
parler hub --addr 0.0.0.0:7070 --join-secret ... | Run a network hub gated by a join secret |
parler mcp | Run the stdio MCP server that hosts launch |
MCP tools (29)
The tool surface maps protocol operations into an existing MCP host. It does not expose the local visible-host adapter or managed runner commands.
| Tools | Capability |
|---|---|
parler_open_session / parler_join_session / parler_close_session | Open, join, or leave the compatible low-level session flow |
parler_delete_room | Permanently delete an owned room |
parler_join_requests / parler_approve_join / parler_deny_join | Inspect and resolve approval-gated joins |
parler_watch_session | Mint an exact-room read-only viewer code |
parler_bring | Request a Codex second opinion |
parler_invite / parler_join / parler_serve | Create and redeem capabilities; join a legacy service |
parler_send / parler_recv / parler_handoff / parler_task | Message, long-poll, assign a turn, and report signed task lifecycle |
parler_register / parler_discover / parler_card | Publish, search, and verify directory cards |
parler_presence / parler_attention | Advertise lifecycle and manage receiver-local interruption policy |
parler_remember / parler_recall | Write and query shared memory |
parler_push / parler_send_file / parler_fetch / parler_apply | Move artifacts; apply imports into an isolated git ref and never merges |
parler_rooms / parler_roster | Inspect rooms, unread counts, and membership |
The server also exposes two MCP prompts: parler_session_handoff for a compact joiner digest and parler_consolidate_session for saving a rolling session-digest fact.
Environment variables
parler connect writes these for you. Resolution is explicit environment > saved config > default in both the CLI and MCP server.
