live2d_parameter · Live2d To Agent MCP: Risk & Policy

WHAT IT DOES

What live2d_parameter does on Live2d To Agent

AI agents invoke live2d_parameter to trigger actions in Live2d To Agent. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why live2d_parameter needs a policy

This tool directly manipulates low-level runtime parameters of a Live2D model, triggering external state changes in the desktop application. It goes beyond a simple read or write of stored data — it actively drives rendering/animation parameters in a running process, making it an Execute-category action.

From the tool's definition 直接操控 Live2D 底层参数 (directly manipulate Live2D low-level parameters)

Verdict

live2d_parameter Rate-limited

live2d_parameter 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Live2d To Agent, so you can run agents against it safely.

FAQ

Questions about live2d_parameter

What does the live2d_parameter tool do? +

直接操控 Live2D 底层参数。参数 ID 因模型而异，通过 live2d_status 获取可用参数。. It is categorised as a Execute tool in the Live2d To Agent MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on live2d_parameter? +

Register the Live2d To Agent MCP server in PolicyLayer and add a rule for live2d_parameter: 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 Live2d To Agent. Nothing to install.

What risk level is live2d_parameter? +

live2d_parameter is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit live2d_parameter? +

Yes. Add a rate_limit block to the live2d_parameter 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 live2d_parameter completely? +

Set action: deny in the PolicyLayer policy for live2d_parameter. 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 live2d_parameter? +

live2d_parameter is provided by the Live2d To Agent MCP server (lmy414/live2d-to-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
