WHAT IT DOES

What performance_framestats does on Claude Mobile

AI agents call performance_framestats to retrieve information from Claude Mobile without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why performance_framestats is rated Low

This tool only reads/collects performance metrics from the device's GPU profiling subsystem. It returns statistical data (percentiles, rates) without modifying any state, executing commands with side effects, or altering the device in any way. Read category with low severity as it only observes rendering performance data.

From the tool's definition Collect frame rendering statistics from GPU profiling. Returns frame time percentiles (p50/p90/p99), jank rate, and slow render percentage.

RECOMMENDED RULE

The rule that runs performance_framestats safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude Mobile, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For performance_framestats, this is the rule to start with:

performance_framestats Allowed

performance_framestats is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Claude Mobile, apply this rule, and every performance_framestats call is checked against it from then on.

FAQ

Questions about performance_framestats

What does the performance_framestats tool do? +

Collect frame rendering statistics from GPU profiling. Returns frame time percentiles (p50/p90/p99), jank rate, and slow render percentage. Android only. It is categorised as a Read tool in the Claude Mobile MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on performance_framestats? +

Register the Claude Mobile MCP server in PolicyLayer and add a rule for performance_framestats: 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 Claude Mobile. Nothing to install.

What risk level is performance_framestats? +

performance_framestats is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit performance_framestats? +

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

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

performance_framestats is provided by the Claude Mobile MCP server (alexgladkov/claude-in-mobile). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
