Use Case · smolagents

Small agents can make big mistakes without rate limits.

smolagents keeps agent code minimal. Civic keeps tool calls controlled, with per-agent limits and cost caps.

use case / smolagents

The lightweight agent made 3,000 API calls in 5 minutes. It was supposed to fetch one report.

Just imagine, one day…

You build a smolagents agent to fetch a weekly sales report from your CRM API. It's a simple agent: read the report endpoint, format the data, return a summary. Minimal code, minimal complexity.

The API returns paginated results. The agent doesn't handle pagination correctly and requests the same page repeatedly with different offset parameters. 3,000 calls in 5 minutes. The CRM API rate-limits your account, your team can't access the CRM for an hour, and you owe $420 in API overage fees.

Minimal code doesn't mean minimal blast radius. A 10-line agent can still generate a $400 bill.

Without rate limits, a pagination bug becomes an account lockout.

It does things you did not intend

You asked for one report. The agent made 3,000 API calls because it couldn't handle pagination correctly.

You cannot prove what happened

3,000 calls to the same endpoint with varying offsets. No structured log of the pagination state or why it looped.

You cannot stop it fast enough

5 minutes before the rate limit kicked in. No circuit breaker. The entire team lost CRM access for an hour.

It gets confused and you never know

The API returned the same data for different offsets (an API quirk). The agent interpreted this as new pages and kept requesting.

Your smolagent calls Civic. Civic enforces rate limits before the API does.

Connectivity

One MCP endpoint for your CRM, reporting tools, and databases. Your smolagent connects through Civic. No raw API keys in the agent.

Guardrails

Read the sales report endpoint. Max 60 calls per minute. If a pagination loop starts, the agent hits Civic's limit, not the CRM's.

Auditability

Every API call logged with parameters and response. See the pagination loop forming before it burns through your quota.

Revocation

Revoke the agent's CRM access without affecting your team's access. One agent's mistake stays one agent's problem.

Connect smolagents through Civic in three steps

smolagents Agent

Add CRM API.

Restrict to read-only endpoints.

Set rate limit to 60 calls per minute.

Done. 1 tool connected:

✓ CRM API — read-only, 60/min limit

Your MCP URL is ready to copy.

Read the docs

The same scenario. Different outcomes.

Without Civic, a pagination bug locks your team out of the CRM. With Civic, the agent hits a rate limit at 60 calls.

$ python sales_agent.py

[smolagent] calling CRM API...

[crm:api] call #1 — offset=0

[crm:api] call #3,000 — rate limit hit

[crm] ✘ account locked for 60 minutes

$ # team can't access CRM. $420 in overages.

$ python sales_agent.py

[smolagent] calling CRM via Civic...

[crm:api] call #1 — offset=0

[nexus] rate limit: 60/min reached

[nexus] ✘ BLOCKED — cooling off

[nexus] anomaly: repeated offset=0 — alert sent

$ # 60 calls. rate limit caught the loop.
