Set active account for tool calls

WHEN AI AGENTS USE THIS TOOL

AI agents use set_active_account to create or modify resources in Cloudflare. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

WHY ENFORCE A POLICY ON SET_ACTIVE_ACCOUNT

Without a policy, an AI agent could call set_active_account repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Cloudflare.

RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.
