Why AssetsController-searchTokens needs a policy

This is a read-only operation that retrieves and queries token data from blockchain. It has no side effects—it does not create, modify, delete, or execute code. The blast radius of misuse is minimal, as an AI agent could only retrieve publicly available blockchain token information without the ability to alter state or incur financial obligations.

From the tool's definition Tool name contains 'search' and description states it searches/queries gateway tokens by type and query. No modification, deletion, execution, or financial operations are performed.

POLICY

How to control AssetsController-searchTokens

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "AssetsController-searchTokens": {}
  }
}

AssetsController-searchTokens 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 Seitrace Insights 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.
