Why api_indexer_search_for_applications needs a policy

The tool performs a read-only search operation on Algorand blockchain applications. It retrieves information matching specified criteria but does not create, modify, delete, or execute transactions. The sibling tools (alpha_create_market_order, alpha_cancel_order, etc.) are financial/execute operations, but this tool is explicitly a search/query function with no side effects.

From the tool's definition Tool name contains 'search_for' and description states 'Search for applications with various criteria' — this is a query operation that retrieves data without modification or side effects.

How to control api_indexer_search_for_applications

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 api_indexer_search_for_applications:

policy.json

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

api_indexer_search_for_applications 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.
