Watch a wallet for order changes via WebSocket and return the first change event. Times out if no orders change. You must provide walletAddress or set ALPHA_MNEMONIC.
AI agents call stream_wallet_orders to retrieve information from Alpha Arcade without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only observes/monitors order changes via WebSocket and returns event data. It does not place, modify, or cancel orders, nor does it move funds. It is purely a read/subscribe operation, though it connects to a live data stream rather than a static query.
From the tool's definition Watch a wallet for order changes via WebSocket and return the first change event. Times out if no orders change.
Documented attack patterns abuse exactly the kind of access stream_wallet_orders gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Alpha Arcade, and nothing reaches the server without passing your rules. This is the rule we recommend for stream_wallet_orders:
{
"version": "1",
"default": "deny",
"tools": {
"stream_wallet_orders": {}
}
}stream_wallet_orders is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Watch a wallet for order changes via WebSocket and return the first change event. Times out if no orders change. You must provide walletAddress or set ALPHA_MNEMONIC. It is categorised as a Read tool in the Alpha Arcade MCP Server, which means it retrieves data without modifying state.
Register the Alpha Arcade MCP server in PolicyLayer and add a rule for stream_wallet_orders: 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 Alpha Arcade. Nothing to install.
stream_wallet_orders is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the stream_wallet_orders rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for stream_wallet_orders. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
stream_wallet_orders is provided by the Alpha Arcade MCP server (phara23/alpha-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Alpha Arcade, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
