summary: "Multi-agent routing: isolated agents, channel accounts, and bindings"
title: "Multi-agent routing"
sidebarTitle: "Multi-agent routing"
read_when: "You want multiple isolated agents (workspaces + auth) in one gateway process."
status: active
---
Run multiple _isolated_ agents in one Gateway process, each with its own workspace, state directory (`agentDir`), and session store, plus multiple channel accounts (e.g. two WhatsApp numbers). Inbound messages route to the right agent through **bindings**.
An **agent** is the full per-persona scope: workspace files, auth profiles, model registry, and session store. A **binding** maps a channel account (a Slack workspace, a WhatsApp number, etc.) to one of those agents.
## What is one agent
Each agent has its own:
- **Workspace**: files, `AGENTS.md`/`SOUL.md`/`USER.md`, local notes, persona rules.
- **State directory** (`agentDir`): auth profiles, model registry, per-agent config.
- **Session store**: chat history and routing state under `~/.openclaw/agents/<agentId>/sessions`.
Auth profiles are per-agent, read from:
```text
~/.openclaw/agents/<agentId>/agent/auth-profiles.json
```
<Note>
`sessions_history` is the safer cross-session recall path: it returns a bounded, redacted view, not a raw transcript dump. It strips thinking-block signatures, tool-result payload details, `<relevant-memories>` scaffolding, tool-call XML tags (`<tool_call>`, `<function_call>`, and their plural/downgraded forms), and MiniMax tool-call XML, then truncates and caps output by byte size.
</Note>
<Warning>
Never reuse `agentDir` across agents — it causes auth/session state collisions. When a secondary agent's local OAuth credential is expired or its refresh fails, OpenClaw reads through to the default/main agent's credential for the same profile id and adopts whichever token is freshest, without copying the refresh token into the secondary agent's store. If you want a fully independent OAuth account, sign in from that agent. If you copy credentials manually, copy only portable static `api_key` or `token` profiles — OAuth refresh material is not portable by default (`copyToAgents` can opt a profile in explicitly).
</Warning>
Skills load from each agent workspace plus shared roots such as `~/.openclaw/skills`, then filter by the effective agent skill allowlist. Use `agents.defaults.skills` for a shared baseline and `agents.list[].skills` for a per-agent replacement (explicit entries replace the default, they do not merge). See [Skills: per-agent vs shared](/tools/skills#per-agent-vs-shared-skills) and [Skills: agent allowlists](/tools/skills#agent-allowlists).
<Note>
**Workspace note:** each agent's workspace is the **default cwd**, not a hard sandbox. Relative paths resolve inside the workspace, but absolute paths can reach other host locations unless sandboxing is enabled. See [Sandboxing](/gateway/sandboxing).
</Note>
## Paths
| What | Default | Override |
| ------------------------- | -------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------- |
| Config | `~/.openclaw/openclaw.json` | `OPENCLAW_CONFIG_PATH` |
| State dir | `~/.openclaw` | `OPENCLAW_STATE_DIR` |
| Default agent's workspace | `~/.openclaw/workspace` (or `workspace-<profile>` when `OPENCLAW_PROFILE` is set) | `agents.list[].workspace`, then `agents.defaults.workspace`, or `OPENCLAW_WORKSPACE_DIR` |
| Other agents' workspace | `<stateDir>/workspace-<agentId>` (or `<agents.defaults.workspace>/<agentId>` when set) | `agents.list[].workspace` |
| Agent dir | `~/.openclaw/agents/<agentId>/agent` | `agents.list[].agentDir` |
| Sessions | `~/.openclaw/agents/<agentId>/sessions` | — |
### Single-agent mode (default)
If you configure nothing, OpenClaw runs one agent:
- `agentId` defaults to `main`.
- Sessions key as `agent:main:<mainKey>` (default `mainKey` is `main`).
- Workspace defaults to `~/.openclaw/workspace` (or `workspace-<profile>` when `OPENCLAW_PROFILE` is set to something other than `default`).
- State defaults to `~/.openclaw/agents/main/agent`.
## Agent helper
Add a new isolated agent:
```bash
openclaw agents add work
```
Flags: `--workspace <dir>`, `--model <id>`, `--agent-dir <dir>`, `--bind <channel[:accountId]>` (repeatable), `--non-interactive` (requires `--workspace`).
Add `bindings` to route inbound messages (the wizard offers to do this for you), then verify:
```bash
openclaw agents list --bindings
```
## Quick start
<Steps>
<Step title="Create each agent workspace">
```bash
openclaw agents add coding
openclaw agents add social
```
Each agent gets its own workspace with `SOUL.md`, `AGENTS.md`, and optional `USER.md`, plus a dedicated `agentDir` and session store under `~/.openclaw/agents/<agentId>`.
</Step>
<Step title="Create channel accounts">
Create one account per agent on your preferred channels:
- Discord: one bot per agent, enable Message Content Intent, copy each token.
- Telegram: one bot per agent via BotFather, copy each token.
- WhatsApp: link each phone number per account.
```bash
openclaw channels login --channel whatsapp --account work
```
See channel guides: [Discord](/channels/discord), [Telegram](/channels/telegram), [WhatsApp](/channels/whatsapp).
</Step>
<Step title="Add agents, accounts, and bindings">
Add agents under `agents.list`, channel accounts under `channels.<channel>.accounts`, and connect them with `bindings` (examples below).
</Step>
<Step title="Restart and verify">
```bash
openclaw gateway restart
openclaw agents list --bindings
openclaw channels status --probe
```
</Step>
</Steps>
## Multiple agents, multiple personas
Each configured `agentId` is a fully isolated persona:
- Different accounts per channel (per `accountId`).
- Different personalities (per-agent `AGENTS.md`/`SOUL.md`).
- Separate auth and sessions, with no cross-talk unless explicitly enabled.
This lets multiple people share one Gateway while keeping their agent state isolated.
## Cross-agent QMD memory search
To let one agent search another agent's QMD session transcripts, add extra collections under `agents.list[].memorySearch.qmd.extraCollections`. Use `agents.defaults.memorySearch.qmd.extraCollections` when every agent should share the same collections.
```json5
{
agents: {
defaults: {
workspace: "~/workspaces/main",
memorySearch: {
qmd: {
extraCollections: [{ path: "~/agents/family/sessions", name: "family-sessions" }],
},
},
},
list: [
{
id: "main",
workspace: "~/workspaces/main",
memorySearch: {
qmd: {
extraCollections: [{ path: "notes" }], // resolves inside workspace -> collection named "notes-main"
},
},
},
{ id: "family", workspace: "~/workspaces/family" },
],
},
memory: {
backend: "qmd",
qmd: { includeDefaultMemory: false },
},
}
```
An extra-collection path can be shared across agents, but its `name` stays explicit when the path is outside the agent workspace. Paths inside the workspace stay agent-scoped so each agent keeps its own transcript search set.
## One WhatsApp number, multiple people (DM split)
Route different WhatsApp DMs to different agents on **one** WhatsApp account by matching sender E.164 (`+15551234567`) with `peer.kind: "direct"`. Replies still come from the same WhatsApp number — there is no per-agent sender identity.
<Note>
Direct chats collapse to the agent's main session key by default, so true isolation requires one agent per person.
</Note>
```json5
{
agents: {
list: [
{ id: "alex", workspace: "~/.openclaw/workspace-alex" },
{ id: "mia", workspace: "~/.openclaw/workspace-mia" },
],
},
bindings: [
{
agentId: "alex",
match: { channel: "whatsapp", peer: { kind: "direct", id: "+15551230001" } },
},
{
agentId: "mia",
match: { channel: "whatsapp", peer: { kind: "direct", id: "+15551230002" } },
},
],
channels: {
whatsapp: {
dmPolicy: "allowlist",
allowFrom: ["+15551230001", "+15551230002"],
},
},
}
```
DM access control (pairing/allowlist) is global per WhatsApp account, not per agent. For shared groups, bind the group to one agent or use [Broadcast groups](/channels/broadcast-groups).
## Routing rules
Bindings are deterministic and most-specific wins. See [Channel routing](/channels/channel-routing#routing-rules-how-an-agent-is-chosen) for the full tier order (exact peer, parent peer, peer wildcard, guild+roles, guild, team, account, channel, default agent). A few rules worth calling out here:
- If multiple bindings match within the same tier, the first one in config order wins.
- If a binding sets multiple match fields (for example `peer` + `guildId`), all specified fields must match (`AND` semantics).
- A binding that omits `accountId` matches only the default account, not every account. Use `accountId: "*"` for a channel-wide fallback, or `accountId: "<name>"` for one account. Adding the same binding again with an explicit account id upgrades the existing channel-only binding instead of duplicating it.
## Multiple accounts / phone numbers
Channels that support multiple accounts (e.g. WhatsApp) use `accountId` to identify each login. Each `accountId` routes to its own agent, so one server can host multiple phone numbers without mixing sessions.
Set `channels.<channel>.defaultAccount` to choose the account used when `accountId` is omitted. When unset, OpenClaw falls back to `default` if present, otherwise the first configured account id (sorted).
Channels supporting multiple accounts: `discord`, `feishu`, `googlechat`, `imessage`, `irc`, `line`, `mattermost`, `matrix`, `nextcloud-talk`, `nostr`, `signal`, `slack`, `telegram`, `whatsapp`, `zalo`, `zalouser`.
## Concepts
- `agentId`: one "brain" (workspace, per-agent auth, per-agent session store).
- `accountId`: one channel account instance (e.g. WhatsApp account `personal` vs `biz`).
- `binding`: routes inbound messages to an `agentId` by `(channel, accountId, peer)`, and optionally guild/team ids.
- Direct chats collapse to `agent:<agentId>:<mainKey>` (per-agent "main"; see `session.mainKey`).
## Platform examples
<AccordionGroup>
<Accordion title="Discord bots per agent">
Each Discord bot account maps to a unique `accountId`. Bind each account to an agent and keep allowlists per bot.
```json5
{
agents: {
list: [
{ id: "main", workspace: "~/.openclaw/workspace-main" },
{ id: "coding", workspace: "~/.openclaw/workspace-coding" },
],
},
bindings: [
{ agentId: "main", match: { channel: "discord", accountId: "default" } },
{ agentId: "coding", match: { channel: "discord", accountId: "coding" } },
],
channels: {
discord: {
groupPolicy: "allowlist",
accounts: {
default: {
token: "DISCORD_BOT_TOKEN_MAIN",
guilds: {
"123456789012345678": {
channels: {
"222222222222222222": { allow: true, requireMention: false },
},
},
},
},
coding: {
token: "DISCORD_BOT_TOKEN_CODING",
guilds: {
"123456789012345678": {
channels: {
"333333333333333333": { allow: true, requireMention: false },
},
},
},
},
},
},
},
}
```
- Invite each bot to the guild and enable Message Content Intent.
- Tokens live in `channels.discord.accounts.<id>.token` (default account can use `DISCORD_BOT_TOKEN`).
</Accordion>
<Accordion title="Telegram bots per agent">
```json5
{
agents: {
list: [
{ id: "main", workspace: "~/.openclaw/workspace-main" },
{ id: "alerts", workspace: "~/.openclaw/workspace-alerts" },
],
},
bindings: [
{ agentId: "main", match: { channel: "telegram", accountId: "default" } },
{ agentId: "alerts", match: { channel: "telegram", accountId: "alerts" } },
],
channels: {
telegram: {
accounts: {
default: {
botToken: "123456:ABC...",
dmPolicy: "pairing",
},
alerts: {
botToken: "987654:XYZ...",
dmPolicy: "allowlist",
allowFrom: ["tg:123456789"],
},
},
},
},
}
```
- Create one bot per agent with BotFather and copy each token.
- Tokens live in `channels.telegram.accounts.<id>.botToken` (default account can use `TELEGRAM_BOT_TOKEN`).
- For multiple bots in the same Telegram group, invite each bot and mention the one that should answer.
- Disable BotFather Privacy Mode for each group bot (`/setprivacy` -> Disable), then remove and re-add the bot so Telegram applies the setting.
- Allow groups with `channels.telegram.groups`, or use `groupPolicy: "open"` only for trusted group deployments.
- Put sender user IDs in `groupAllowFrom`. Group and supergroup IDs belong in `channels.telegram.groups`, not `groupAllowFrom`.
- Bind by `accountId` so each bot routes to its own agent.
</Accordion>
<Accordion title="WhatsApp numbers per agent">
Link each account before starting the gateway:
```bash
openclaw channels login --channel whatsapp --account personal
openclaw channels login --channel whatsapp --account biz
```
`~/.openclaw/openclaw.json` (JSON5):
```js
{
agents: {
list: [
{
id: "home",
default: true,
name: "Home",
workspace: "~/.openclaw/workspace-home",
agentDir: "~/.openclaw/agents/home/agent",
},
{
id: "work",
name: "Work",
workspace: "~/.openclaw/workspace-work",
agentDir: "~/.openclaw/agents/work/agent",
},
],
},
// Deterministic routing: first match wins (most-specific first).
bindings: [
{ agentId: "home", match: { channel: "whatsapp", accountId: "personal" } },
{ agentId: "work", match: { channel: "whatsapp", accountId: "biz" } },
// Optional per-peer override (example: send a specific group to work agent).
{
agentId: "work",
match: {
channel: "whatsapp",
accountId: "personal",
peer: { kind: "group", id: "1203630...@g.us" },
},
},
],
// Off by default: agent-to-agent messaging must be explicitly enabled + allowlisted.
tools: {
agentToAgent: {
enabled: false,
allow: ["home", "work"],
},
},
channels: {
whatsapp: {
accounts: {
personal: {
// Optional override. Default: ~/.openclaw/credentials/whatsapp/personal
// authDir: "~/.openclaw/credentials/whatsapp/personal",
},
biz: {
// Optional override. Default: ~/.openclaw/credentials/whatsapp/biz
// authDir: "~/.openclaw/credentials/whatsapp/biz",
},
},
},
},
}
```

</AccordionGroup>
## Common patterns
<Tabs>
<Tab title="WhatsApp daily + Telegram deep work">
Split by channel: route WhatsApp to a fast everyday agent and Telegram to an Opus agent.
```json5
{
agents: {
list: [
{
id: "chat",
name: "Everyday",
workspace: "~/.openclaw/workspace-chat",
model: "anthropic/claude-sonnet-4-6",
},
{
id: "opus",
name: "Deep Work",
workspace: "~/.openclaw/workspace-opus",
model: "anthropic/claude-opus-4-6",
},
],
},
bindings: [
{ agentId: "chat", match: { channel: "whatsapp", accountId: "*" } },
{ agentId: "opus", match: { channel: "telegram", accountId: "*" } },
],
}
```
These examples use `accountId: "*"` so the bindings keep working if you add accounts later. To route a single DM/group to Opus while keeping the rest on chat, add a `match.peer` binding for that peer — peer matches always win over channel-wide rules.
</Tab>
<Tab title="Same channel, one peer to Opus">
Keep WhatsApp on the fast agent, but route one DM to Opus:
```json5
{
agents: {
list: [
{
id: "chat",
name: "Everyday",
workspace: "~/.openclaw/workspace-chat",
model: "anthropic/claude-sonnet-4-6",
},
{
id: "opus",
name: "Deep Work",
workspace: "~/.openclaw/workspace-opus",
model: "anthropic/claude-opus-4-6",
},
],
},
bindings: [
{
agentId: "opus",
match: { channel: "whatsapp", accountId: "*", peer: { kind: "direct", id: "+15551234567" } },
},
{ agentId: "chat", match: { channel: "whatsapp", accountId: "*" } },
],
}
```
Peer bindings always win, so keep them above the channel-wide rule.
</Tab>
<Tab title="Family agent bound to a WhatsApp group">
Bind a dedicated family agent to a single WhatsApp group, with mention gating and a tighter tool policy:
```json5
{
agents: {
list: [
{
id: "family",
name: "Family",
workspace: "~/.openclaw/workspace-family",
identity: { name: "Family Bot" },
groupChat: {
mentionPatterns: ["@family", "@familybot", "@Family Bot"],
},
sandbox: {
mode: "all",
scope: "agent",
},
tools: {
allow: [
"exec",
"read",
"sessions_list",
"sessions_history",
"sessions_send",
"sessions_spawn",
"session_status",
],
deny: ["write", "edit", "apply_patch", "browser", "canvas", "nodes", "cron"],
},
},
],
},
bindings: [
{
agentId: "family",
match: {
channel: "whatsapp",
peer: { kind: "group", id: "120363999999999999@g.us" },
},
},
],
}
```
Tool allow/deny lists are **tools**, not skills. If a skill needs to run a binary, ensure `exec` is allowed and the binary exists in the sandbox. For stricter gating, set `agents.list[].groupChat.mentionPatterns` and keep group allowlists enabled for the channel.
</Tab>
</Tabs>
## Per-agent sandbox and tool configuration
Each agent can have its own sandbox and tool restrictions:
```js
{
agents: {
list: [
{
id: "personal",
workspace: "~/.openclaw/workspace-personal",
sandbox: {
mode: "off", // No sandbox for personal agent
},
// No tool restrictions - all tools available
},
{
id: "family",
workspace: "~/.openclaw/workspace-family",
sandbox: {
mode: "all", // Always sandboxed
scope: "agent", // One container per agent
docker: {
// Optional one-time setup after container creation
setupCommand: "apt-get update && apt-get install -y git curl",
},
},
tools: {
allow: ["read"], // Only read tool
deny: ["exec", "write", "edit", "apply_patch"], // Deny others
},
},
],
},
}
```
<Note>
`setupCommand` lives under `sandbox.docker` and runs once on container creation. Per-agent `sandbox.docker.*` overrides are ignored when the resolved scope is `"shared"`.
</Note>
This gives you:
- **Security isolation**: restrict tools for untrusted agents.
- **Resource control**: sandbox specific agents while keeping others on host.
- **Flexible policies**: different permissions per agent.
<Note>
`tools.elevated` has both a global gate (`tools.elevated.enabled`/`allowFrom`) and a per-agent gate (`agents.list[].tools.elevated.enabled`/`allowFrom`). The per-agent gate can only further restrict the global one — both must allow a sender for elevated commands to run. For group targeting, use `agents.list[].groupChat.mentionPatterns` so @mentions map cleanly to the intended agent.
</Note>
