POLICY

How to control Reference Data

PolicyLayer is an MCP gateway — it sits between your AI agents and Reference Data, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "compute_vat": {
    "limits": [
      {
        "counter": "compute_vat_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "check_minimum_wage": {
    "limits": [
      {
        "counter": "check_minimum_wage_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Create a free account and register Reference Data — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Reference Data

How do I prevent bulk modifications through Reference Data? +

The Reference Data server has 1 write tools including compute_vat. 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 Reference Data.

How many tools does the Reference Data MCP server expose? +

10 tools across 2 categories: Read, Write. 9 are read-only. 1 can modify, create, or delete data.

How do I enforce a policy on Reference Data? +

Register the Reference Data 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.

Enforce policy on every Reference Data tool call.

Deterministic rules across all 10 Reference Data tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
