Why alpha_get_orderbook needs a policy

This tool retrieves and queries orderbook data from the Algorand blockchain. It performs read-only operations with no state modification, financial commitment, or execution of external actions. The 'Fetch' verb and presentation of market data (unified view, spread calculation) confirm pure data retrieval.

From the tool's definition Tool name includes 'get_' and description states 'Fetch the on-chain orderbook' with no side effects. Returns data only (bids, asks, spread) without modifying state or triggering transactions.

POLICY

How to control alpha_get_orderbook

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

policy.json

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

alpha_get_orderbook 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 Algorand MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
