Why get_supported_bridges needs a policy

This tool retrieves informational data about supported bridge protocols. It performs a read-only query with no capability to modify state, execute transactions, or cause irreversible changes. The low severity reflects minimal risk even if an AI agent calls it repeatedly, as it only returns configuration/capability data.

From the tool's definition Tool name is 'get_supported_bridges' and description states 'List all supported bridge protocols and their capabilities' — explicitly a query/list operation with no mutations or side effects.

How to control get_supported_bridges

PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_supported_bridges:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_supported_bridges": {}
  }
}

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

  1. Create a free account and register Sperax Ecosystem Crypto & DeFI MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
