# Multi-Agent Sandbox & Tools Configuration
|
||||
|
||||
## Overview
|
||||
|
||||
Each agent in a multi-agent setup can now have its own:
|
||||
- **Sandbox configuration** (`agents.list[].sandbox` overrides `agents.defaults.sandbox`)
|
||||
- **Tool restrictions** (`tools.allow` / `tools.deny`, plus `agents.list[].tools`)
|
||||
|
||||
This allows you to run multiple agents with different security profiles:
|
||||
- Personal assistant with full access
|
||||
- Family/work agents with restricted tools
|
||||
- Public-facing agents in sandboxes
|
||||
|
||||
`setupCommand` belongs under `sandbox.docker` (global or per-agent) and runs once
|
||||
when the container is created.
|
||||
|
||||
Auth is per-agent: each agent reads from its own `agentDir` auth store at:
|
||||
|
||||
```
|
||||
~/.clawdbot/agents/<agentId>/agent/auth-profiles.json
|
||||
```
|
||||
|
||||
Credentials are **not** shared between agents. Never reuse `agentDir` across agents.
|
||||
If you want to share creds, copy `auth-profiles.json` into the other agent's `agentDir`.
|
||||
|
||||
For how sandboxing behaves at runtime, see [Sandboxing](/gateway/sandboxing).
|
||||
For debugging “why is this blocked?”, see [Sandbox vs Tool Policy vs Elevated](/gateway/sandbox-vs-tool-policy-vs-elevated) and `moltbot sandbox explain`.

|
||||
## Configuration Examples
|
||||
|
||||
### Example 1: Personal + Restricted Family Agent
|
||||
|
||||
```json
|
||||
{
|
||||
"agents": {
|
||||
"list": [
|
||||
{
|
||||
"id": "main",
|
||||
"default": true,
|
||||
"name": "Personal Assistant",
|
||||
"workspace": "~/clawd",
|
||||
"sandbox": { "mode": "off" }
|
||||
},
|
||||
{
|
||||
"id": "family",
|
||||
"name": "Family Bot",
|
||||
"workspace": "~/clawd-family",
|
||||
"sandbox": {
|
||||
"mode": "all",
|
||||
"scope": "agent"
|
||||
},
|
||||
"tools": {
|
||||
"allow": ["read"],
|
||||
"deny": ["exec", "write", "edit", "apply_patch", "process", "browser"]
|
||||
}
|
||||
}
|
||||
]
|
||||
},
|
||||
"bindings": [
|
||||
{
|
||||
"agentId": "family",
|
||||
"match": {
|
||||
"provider": "whatsapp",
|
||||
"accountId": "*",
|
||||
"peer": {
|
||||
"kind": "group",
|
||||
"id": "120363424282127706@g.us"
|
||||
}
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Result:**
|
||||
- `main` agent: Runs on host, full tool access
|
||||
- `family` agent: Runs in Docker (one container per agent), only `read` tool
|
||||
|
||||

|
||||
|
||||
### Example 2: Work Agent with Shared Sandbox
|
||||
|
||||
```json
|
||||
{
|
||||
"agents": {
|
||||
"list": [
|
||||
{
|
||||
"id": "personal",
|
||||
"workspace": "~/clawd-personal",
|
||||
"sandbox": { "mode": "off" }
|
||||
},
|
||||
{
|
||||
"id": "work",
|
||||
"workspace": "~/clawd-work",
|
||||
"sandbox": {
|
||||
"mode": "all",
|
||||
"scope": "shared",
|
||||
"workspaceRoot": "/tmp/work-sandboxes"
|
||||
},
|
||||
"tools": {
|
||||
"allow": ["read", "write", "apply_patch", "exec"],
|
||||
"deny": ["browser", "gateway", "discord"]
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Example 2b: Global coding profile + messaging-only agent
|
||||
|
||||
```json
|
||||
{
|
||||
"tools": { "profile": "coding" },
|
||||
"agents": {
|
||||
"list": [
|
||||
{
|
||||
"id": "support",
|
||||
"tools": { "profile": "messaging", "allow": ["slack"] }
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Result:**
|
||||
- default agents get coding tools
|
||||
- `support` agent is messaging-only (+ Slack tool)
|
||||
|
||||
---
|
||||
|
||||
### Example 3: Different Sandbox Modes per Agent
|
||||
|
||||
```json
|
||||
{
|
||||
"agents": {
|
||||
"defaults": {
|
||||
"sandbox": {
|
||||
"mode": "non-main", // Global default
|
||||
"scope": "session"
|
||||
}
|
||||
},
|
||||
"list": [
|
||||
{
|
||||
"id": "main",
|
||||
"workspace": "~/clawd",
|
||||
"sandbox": {
|
||||
"mode": "off" // Override: main never sandboxed
|
||||
}
|
||||
},
|
||||
{
|
||||
"id": "public",
|
||||
"workspace": "~/clawd-public",
|
||||
"sandbox": {
|
||||
"mode": "all", // Override: public always sandboxed
|
||||
"scope": "agent"
|
||||
},
|
||||
"tools": {
|
||||
"allow": ["read"],
|
||||
"deny": ["exec", "write", "edit", "apply_patch"]
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Configuration Precedence
|
||||
|
||||
When both global (`agents.defaults.*`) and agent-specific (`agents.list[].*`) configs exist:
|
||||
|
||||
### Sandbox Config
|
||||
Agent-specific settings override global:
|
||||
```
|
||||
agents.list[].sandbox.mode > agents.defaults.sandbox.mode
|
||||
agents.list[].sandbox.scope > agents.defaults.sandbox.scope
|
||||
agents.list[].sandbox.workspaceRoot > agents.defaults.sandbox.workspaceRoot
|
||||
agents.list[].sandbox.workspaceAccess > agents.defaults.sandbox.workspaceAccess
|
||||
agents.list[].sandbox.docker.* > agents.defaults.sandbox.docker.*
|
||||
agents.list[].sandbox.browser.* > agents.defaults.sandbox.browser.*
|
||||
agents.list[].sandbox.prune.* > agents.defaults.sandbox.prune.*
|
||||
```
|
||||
|
||||
**Notes:**
|
||||
- `agents.list[].sandbox.{docker,browser,prune}.*` overrides `agents.defaults.sandbox.{docker,browser,prune}.*` for that agent (ignored when sandbox scope resolves to `"shared"`).
|
||||
|
||||
### Tool Restrictions
|
||||
The filtering order is:
|
||||
1. **Tool profile** (`tools.profile` or `agents.list[].tools.profile`)
|
||||
2. **Provider tool profile** (`tools.byProvider[provider].profile` or `agents.list[].tools.byProvider[provider].profile`)
|
||||
3. **Global tool policy** (`tools.allow` / `tools.deny`)
|
||||
4. **Provider tool policy** (`tools.byProvider[provider].allow/deny`)
|
||||
5. **Agent-specific tool policy** (`agents.list[].tools.allow/deny`)
|
||||
6. **Agent provider policy** (`agents.list[].tools.byProvider[provider].allow/deny`)
|
||||
7. **Sandbox tool policy** (`tools.sandbox.tools` or `agents.list[].tools.sandbox.tools`)
|
||||
8. **Subagent tool policy** (`tools.subagents.tools`, if applicable)
|
||||
|
||||
Each level can further restrict tools, but cannot grant back denied tools from earlier levels.
|
||||
If `agents.list[].tools.sandbox.tools` is set, it replaces `tools.sandbox.tools` for that agent.
|
||||
If `agents.list[].tools.profile` is set, it overrides `tools.profile` for that agent.
|
||||
Provider tool keys accept either `provider` (e.g. `google-antigravity`) or `provider/model` (e.g. `openai/gpt-5.2`).
|
||||
|
||||
### Tool groups (shorthands)
|
||||
|
||||
Tool policies (global, agent, sandbox) support `group:*` entries that expand to multiple concrete tools:
|
||||
|
||||
- `group:runtime`: `exec`, `bash`, `process`
|
||||
- `group:fs`: `read`, `write`, `edit`, `apply_patch`
|
||||
- `group:sessions`: `sessions_list`, `sessions_history`, `sessions_send`, `sessions_spawn`, `session_status`
|
||||
- `group:memory`: `memory_search`, `memory_get`
|
||||
- `group:ui`: `browser`, `canvas`
|
||||
- `group:automation`: `cron`, `gateway`
|
||||
- `group:messaging`: `message`
|
||||
- `group:nodes`: `nodes`
|
||||
- `group:moltbot`: all built-in Moltbot tools (excludes provider plugins)
|
||||
|
||||
### Elevated Mode
|
||||
`tools.elevated` is the global baseline (sender-based allowlist). `agents.list[].tools.elevated` can further restrict elevated for specific agents (both must allow).
|
||||
|
||||
Mitigation patterns:
|
||||
- Deny `exec` for untrusted agents (`agents.list[].tools.deny: ["exec"]`)
|
||||
- Avoid allowlisting senders that route to restricted agents
|
||||
- Disable elevated globally (`tools.elevated.enabled: false`) if you only want sandboxed execution
|
||||
- Disable elevated per agent (`agents.list[].tools.elevated.enabled: false`) for sensitive profiles
|
||||

|
||||
## Migration from Single Agent
|
||||
|
||||
**Before (single agent):**
|
||||
```json
|
||||
{
|
||||
"agents": {
|
||||
"defaults": {
|
||||
"workspace": "~/clawd",
|
||||
"sandbox": {
|
||||
"mode": "non-main"
|
||||
}
|
||||
}
|
||||
},
|
||||
"tools": {
|
||||
"sandbox": {
|
||||
"tools": {
|
||||
"allow": ["read", "write", "apply_patch", "exec"],
|
||||
"deny": []
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**After (multi-agent with different profiles):**
|
||||
```json
|
||||
{
|
||||
"agents": {
|
||||
"list": [
|
||||
{
|
||||
"id": "main",
|
||||
"default": true,
|
||||
"workspace": "~/clawd",
|
||||
"sandbox": { "mode": "off" }
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Legacy `agent.*` configs are migrated by `moltbot doctor`; prefer `agents.defaults` + `agents.list` going forward.
|
||||
|
||||
---
|
||||
|
||||
## Tool Restriction Examples
|
||||
|
||||
### Read-only Agent
|
||||
```json
|
||||
{
|
||||
"tools": {
|
||||
"allow": ["read"],
|
||||
"deny": ["exec", "write", "edit", "apply_patch", "process"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Safe Execution Agent (no file modifications)
|
||||
```json
|
||||
{
|
||||
"tools": {
|
||||
"allow": ["read", "exec", "process"],
|
||||
"deny": ["write", "edit", "apply_patch", "browser", "gateway"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Communication-only Agent
|
||||
```json
|
||||
{
|
||||
"tools": {
|
||||
"allow": ["sessions_list", "sessions_send", "sessions_history", "session_status"],
|
||||
"deny": ["exec", "write", "edit", "apply_patch", "read", "browser"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Common Pitfall: "non-main"
|
||||
|
||||
`agents.defaults.sandbox.mode: "non-main"` is based on `session.mainKey` (default `"main"`),
|
||||
not the agent id. Group/channel sessions always get their own keys, so they
|
||||
are treated as non-main and will be sandboxed. If you want an agent to never
|
||||
sandbox, set `agents.list[].sandbox.mode: "off"`.
|
||||
|
||||
---
|
||||
|
||||
## Testing
|
||||
|
||||
After configuring multi-agent sandbox and tools:
|
||||
|
||||
1. **Check agent resolution:**
|
||||
```exec
|
||||
moltbot agents list --bindings
|
||||
```
|
||||
|
||||
2. **Verify sandbox containers:**
|
||||
```exec
|
||||
docker ps --filter "label=moltbot.sandbox=1"
|
||||
```
|
||||
|
||||
3. **Test tool restrictions:**
|
||||
- Send a message requiring restricted tools
|
||||
- Verify the agent cannot use denied tools
|
||||
|
||||
4. **Monitor logs:**
|
||||
```exec
|
||||
tail -f "${CLAWDBOT_STATE_DIR:-$HOME/.clawdbot}/logs/gateway.log" | grep -E "routing|sandbox|tools"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Agent not sandboxed despite `mode: "all"`
|
||||
- Check if there's a global `agents.defaults.sandbox.mode` that overrides it
|
||||
- Agent-specific config takes precedence, so set `agents.list[].sandbox.mode: "all"`
|
||||
|
||||
### Tools still available despite deny list
|
||||
- Check tool filtering order: global → agent → sandbox → subagent
|
||||
- Each level can only further restrict, not grant back
|
||||
- Verify with logs: `[tools] filtering tools for agent:${agentId}`
|
||||
|
||||
### Container not isolated per agent
|
||||
- Set `scope: "agent"` in agent-specific sandbox config
|
||||
- Default is `"session"` which creates one container per session
