OpenClaw Group Access Control and Mention Gating

February 21, 20263 min readReviewed March 8, 2026

Group channels are where autonomous assistants create the most risk. OpenClaw ships policy controls for group participation, mention requirements, and allowlists so you can move from safe defaults to broader automation in controlled steps[1][2].

Three Controls That Matter

Group policy: defines whether the bot may respond in groups/channels.
Require mention: avoids ambient responses in high-noise rooms.
Allowlist: only approved groups/users can trigger the agent[2].

Conservative Security Baseline

{
  "channels": {
    "slack": { "groupPolicy": "allowlist", "requireMention": true },
    "discord": { "groupPolicy": "allowlist", "requireMention": true },
    "msteams": { "groupPolicy": "allowlist", "requireMention": true }
  }
}

Why Mention Gating Works

Mention gating reduces accidental prompt injection in public channels and keeps replies anchored to explicit intent. It also reduces token burn from ambient chatter.

Session Isolation for Groups

OpenClaw uses non-main session keys for groups/channels, which helps separate group context from direct-message context[3]. This makes memory leakage across chat surfaces less likely when configuration is correct.

Operator Workflow

openclaw channels status --probe
openclaw channels capabilities --channel slack
openclaw logs --follow

After policy changes, validate runtime state immediately to catch permission drift or connector-side regressions[4][5].

Production Guardrails

Start with allowlist + mention required.
Expand one channel at a time and track errors.
Use channel-specific sessions for sensitive teams.
Review policy after each major model/tooling change.
