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 VNStock Agent MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:
{
"crypto_history": {
"limits": [
{
"counter": "crypto_history_per_minute",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
} Controls API costs and prevents retry loops from exhausting upstream rate limits.
Free to start. No card required.
