Why call_waapi needs a policy

This tool permits execution of arbitrary WAAPI functions with user-supplied arguments and options. While WAAPI itself is legitimate and necessary for Wwise automation, the 'any' qualifier means an AI agent could invoke destructive or Write operations (create, modify, delete project elements) depending on what WAAPI functions exist and what arguments are passed.

From the tool's definition Tool description states it will 'Execute any WAAPI function with the given args and options.' The word 'Execute' combined with 'any' function indicates arbitrary code/API execution capability.

POLICY

How to control call_waapi

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "call_waapi": {
      "limits": [
        {
          "counter": "call_waapi_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

call_waapi stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register SK Wwise MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about call_waapi

What does the call_waapi tool do? +

Execute any WAAPI function with the given args and options. It is categorised as a Execute tool in the SK Wwise MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on call_waapi? +

Register the SK Wwise MCP server in PolicyLayer and add a rule for call_waapi: 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 SK Wwise MCP. Nothing to install.

What risk level is call_waapi? +

call_waapi is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit call_waapi? +

Yes. Add a rate_limit block to the call_waapi 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.

How do I block call_waapi completely? +

Set action: deny in the PolicyLayer policy for call_waapi. 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.

What MCP server provides call_waapi? +

call_waapi is provided by the SK Wwise MCP server (silver-rain-dev/sk-wwise-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every SK Wwise MCP tool call.

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