# Set policy limits

> Configure per-tx and daily USDC caps, allow/deny lists, and pause in the dashboard.

# Set policy limits

Policy is configured in the Hub dashboard for a selected agent. Agents can **read** policy via MCP (`get_policy_status`) but cannot change it.

<Steps>
  <Step title="Open Policy">
    Sign in on [testnet](https://testnet.nebulaonchain.xyz) or [mainnet](https://mainnet.nebulaonchain.xyz) → select the agent → **Policy**.
  </Step>

  <Step title="Set caps">
    Set per-transaction and daily USDC caps. Keep micro-payments under the threshold you intend for autonomous spend; larger amounts can require [confirmations](/concepts/confirmations).
  </Step>

  <Step title="Allow / deny">
    Optionally restrict destinations with allowlists or block addresses with denylists. Pause blocks all spend until you clear it.
  </Step>
</Steps>

Policy is scoped to the agent's network. A testnet agent does not share caps with a mainnet twin. See [Networks](/networks) and [Spending policy](/concepts/spending-policy).
