Agent Builder limits
Agent Builder respects organization plan limits and includes guardrails to prevent runaway automation loops.
Plan gates
Section titled “Plan gates”Agent Builder checks your plan before confirming writes. If a change would exceed quota, the preview shows a blocking warning.
| Resource | Free | Starter | Standard | Pro | Enterprise |
|---|---|---|---|---|---|
| Assistants | 1 | 3 | 10 | 30 | Custom |
| Knowledge bases | 1 | 1 | 3 | 15 | Custom |
| Tools (API Request / MCP) | — | API Request | API + MCP | API + MCP | Custom |
| Agent Builder sessions/day | 5 | 25 | 100 | 200 | Custom |
| Confirmed writes/session | 10 | 25 | 50 | 75 | Custom |
Exact quotas match Plan limits and Plans compared.
Blocked preview example
Section titled “Blocked preview example”⛔ Cannot attach tool: Starter plan does not include MCP tools.Upgrade to Standard or use an API Request tool instead.No write occurs until the conflict is resolved.
Circuit breaker
Section titled “Circuit breaker”If Agent Builder detects a loop — repeated failed API calls, identical replans, or excessive tool tests — it pauses execution:
| Signal | Threshold | Action |
|---|---|---|
| Failed API calls | 3 consecutive | Pause + show error detail |
| Replan attempts | 5 without confirmation | Stop and ask you to rephrase |
| Tool test calls | 10 in one session | Require explicit “continue testing” |
| Session duration | 30 minutes idle | Session expires |
Resume by starting a new request or typing “continue” when prompted after a soft pause.
Token and cost awareness
Section titled “Token and cost awareness”Agent Builder sessions consume LLM tokens like assistant conversations. The dashboard usage panel includes Agent Builder usage under Configuration.
| Tip | Benefit |
|---|---|
| Batch related changes in one confirmed action | Fewer plan/review cycles |
| Use read-only queries for exploration | No write quota consumed |
| Avoid “test every SKU” loops | Stays under circuit breaker |
Rate limits
Section titled “Rate limits”Agent Builder API calls share your organization’s global rate limit (1,000 req/min). Heavy automation should use the REST API directly with an API key.
