press-key · TgeBrowser MCP Server MCP: Risk & Policy

WHAT IT DOES

What press-key does on TgeBrowser MCP Server

AI agents invoke press-key to trigger actions in TgeBrowser MCP Server. 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 press-key needs a policy

Pressing a key is an interactive browser action that executes input events within the automated browser. It can trigger form submissions, navigation, scripts, or other side effects depending on context. This falls under Execute as it performs external browser operations whose effects depend on arguments (which key is pressed and in what context).

Verdict

press-key Rate-limited

press-key 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.

What risk level is press-key? +

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

Can I rate-limit press-key? +

Yes. Add a rate_limit block to the press-key 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 press-key completely? +

Set action: deny in the PolicyLayer policy for press-key. 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.
