Preventing tool and API abuse by AI agents

Controls for agents that call APIs, trigger workflows, send messages, query databases, or update records.

Tools Create Business Impact

Tool calls move agents from text generation into operational change. Without policy, an injected instruction can make an agent retrieve, modify, send, delete, or export data.

Classify Tools

Group tools by impact: read-only, internal lookup, external communication, financial action, administrative change, data export, and irreversible operation. Each class needs different control strength.

Runtime Enforcement

Evaluate tool name, parameters, user identity, data class, destination, and chain of reasoning context before execution. Deny, redact, require approval, or allow with logging.

Abuse Testing

Red team prompts should try to coerce tools, bypass approvals, exfiltrate data, or exploit weak parameter validation. Findings should improve both agent design and policy.
