Even read-only tools carry cost. An agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up bills.
PolicyLayer is an MCP gateway — it sits between your AI agents and HelloBooks AI MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:
{
"analyze_balance_sheet": {
"limits": [
{
"counter": "analyze_balance_sheet_per_minute",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
} Controls API costs and prevents retry loops from exhausting upstream rate limits.
Instant setup, no code required.

Register the HelloBooks AI MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly.
