WHAT CAN GO WRONG

Destructive tools (bighub_api_keys_delete, bighub_constraints_delete, bighub_constraints_purge_idempotency) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.

Write operations (bighub_actions_live_connect, bighub_actions_live_disconnect, bighub_api_keys_create) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.

Execute tools (bighub_actions_dry_run, bighub_constraints_dry_run, bighub_insights_learn) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.

RECOMMENDED RULES

Deny destructive operations

{
  "bighub_api_keys_delete": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "bighub_actions_live_connect": {
    "limits": [
      {
        "counter": "bighub_actions_live_connect_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "bighub_actions_dashboard_summary": {
    "limits": [
      {
        "counter": "bighub_actions_dashboard_summary_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

FAQ

Can an AI agent delete data through the BIGHUB MCP server? +

Yes. The BIGHUB server exposes 4 destructive tools including bighub_api_keys_delete, bighub_constraints_delete, bighub_constraints_purge_idempotency. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through BIGHUB? +

The BIGHUB server has 17 write tools including bighub_actions_live_connect, bighub_actions_live_disconnect, bighub_api_keys_create. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach BIGHUB.

How many tools does the BIGHUB MCP server expose? +

125 tools across 4 categories: Destructive, Execute, Read, Write. 100 are read-only. 25 can modify, create, or delete data.

How do I enforce a policy on BIGHUB? +

Register the BIGHUB 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. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
