POLICY

How to control 3dassets

PolicyLayer is an MCP gateway — it sits between your AI agents and 3dassets, and nothing reaches the server without passing your rules. These are the rules we recommend:

Block financial tools by default

{
  "finalize_upload": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Requires human approval."
      }
    ]
  }
}

Financial tools should be explicitly enabled per use case, not open by default.

Rate limit write operations

{
  "create_account": {
    "limits": [
      {
        "counter": "create_account_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_asset": {
    "limits": [
      {
        "counter": "get_asset_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 3dassets — 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 3dassets

Can an AI agent move money through the 3dassets MCP server? +

Yes. The 3dassets server exposes 1 financial tools including finalize_upload. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.

How do I prevent bulk modifications through 3dassets? +

The 3dassets server has 4 write tools including create_account, submit_asset_from_url, submit_pack. 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 3dassets.

How many tools does the 3dassets MCP server expose? +

20 tools across 3 categories: Financial, Read, Write. 15 are read-only. 5 can modify, create, or delete data.

How do I enforce a policy on 3dassets? +

Register the 3dassets 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 3dassets tool call.

Deterministic rules across all 20 3dassets tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
