Why make_asset_create_txn needs a policy

Creating an asset is a reversible write operation that adds new data to the blockchain. While this is a significant action (hence 'high' severity—an AI could create unwanted assets or spam the chain), it is not destructive (assets can be deleted), not financial per se (though it may incur fees), and not execution of arbitrary code.

From the tool's definition Tool is named 'make_asset_create_txn' and described as 'Create an asset creation transaction'. The verb 'Create' and 'asset creation' indicate it generates a new blockchain asset, which is a write operation that modifies the Algorand blockchain state.

POLICY

How to control make_asset_create_txn

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 make_asset_create_txn:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "make_asset_create_txn": {
      "limits": [
        {
          "counter": "make_asset_create_txn_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

make_asset_create_txn stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

How do I enforce a policy on make_asset_create_txn? +

Register the Algorand MCP server in PolicyLayer and add a rule for make_asset_create_txn: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Algorand MCP. Nothing to install.

What risk level is make_asset_create_txn? +

make_asset_create_txn is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit make_asset_create_txn? +

How do I block make_asset_create_txn completely? +

Enforce policy on every Algorand MCP tool call.

Start from Algorand MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
