Classification as Read is appropriate because the action is purely informational query with no destructive or financial transaction capability.

From the tool's definition Tool name 'get_account_balance' and description 'Get remaining SocialData account balance in USD' indicate a read-only query operation that retrieves account balance information without modifying, executing, or deleting anything.

POLICY

How to control get_account_balance

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

policy.json

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

get_account_balance 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 SocialData 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.
