The most dangerous Neo N3 MCP Server tools

9 of Neo N3 MCP Server's 27 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

How to control Neo N3 MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and Neo N3 MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Block financial tools by default
{
  "claim_gas": {
    "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_wallet": {
    "limits": [
      {
        "counter": "create_wallet_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "estimate_invoke_fees": {
    "limits": [
      {
        "counter": "estimate_invoke_fees_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

  1. Create a free account and register Neo N3 MCP Server — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I prevent bulk modifications through Neo N3 MCP Server? +

The Neo N3 MCP Server server has 4 write tools including create_wallet, import_wallet, neofs_create_container. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour.
