Misuse poses minimal security risk.

From the tool's definition Tool name 'kaspa_validate_address' and description 'Validate a Kaspa address' indicate a query/verification operation with no side effects.

POLICY

How to control kaspa_validate_address

PolicyLayer is an MCP gateway — it sits between your AI agents and Kaspa MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for kaspa_validate_address:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "kaspa_validate_address": {}
  }
}

kaspa_validate_address is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Kaspa MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
