Why plugins_get_manifest needs a policy

This tool retrieves metadata about plugin manifests. It has no side effects—it only fetches and returns configuration and capability information. This is a read-only informational query, similar to 'get' or 'list' operations. Even in a financial/DeFi context, merely reading plugin metadata poses minimal risk unless the metadata itself could be exploited, which is unlikely for manifest documents.

From the tool's definition Tool name 'plugins_get_manifest' and description 'Get detailed plugin manifest including all available functions, parameters, and configuration' indicate a query/retrieval operation that returns information about plugin capabilities without modifying state.

POLICY

How to control plugins_get_manifest

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 plugins_get_manifest:

policy.json

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

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