| Content-intensive task budget | Documents, projects, official KB evidence tasks (higher quota) |
Standard Budget Default Items
| Limit Item | Default | Purpose |
|---|---|---|
| Cumulative input Token limit | 1,000,000 | Controls total input |
| Model iteration limit | 50 | Controls AI thinking rounds |
| Tool call limit | 200 | Controls tool call count |
| Stop-start new round time limit (min) | 30 | Total duration |
| Consecutive no-progress limit | 5 | Prevents idle loops |
NOTE
Changes only take effect on newly started tasks. Running tasks use the snapshot config at launch time.
6. Official Service Detection

Verifies whether the two core services provided by Mbbrowser official are available:
1. Mbbrowser RAG Knowledge Base
- Issue read-only authenticated queries via Mbbrowser official RAG retrieval link
- Detect: network connection, account auth, response format, available knowledge result
- Status: Normal / Abnormal / Disabled / Checking
2. Mbbrowser Client ControlV2
- Perform real-time ControlV2 readiness round-trip detection with the selected Mbbrowser client
- Verify: instance discovery, handshake, account login, config loading, executable capability
- Status: Normal / Abnormal / Disabled / Checking
Detection Trigger Method
- Manual: Click "Start Detection" / "Re-detect" on the settings page
- Auto: Auto-detect once when MBAgent starts
TIP
Prioritize detection when issues arise:
- "AI can't operate Mbbrowser" → check if ControlV2 is normal
- "AI says it can't find official material" → check if RAG is normal
- When status is Abnormal, contact Mbbrowser customer support per the error message
