interact · Mcp Selenium MCP: Risk & Policy

WHAT IT DOES

What interact does on Mcp Selenium

AI agents invoke interact to trigger actions in Mcp Selenium. 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 interact needs a policy

Mouse actions (clicks, drags, hovers) on browser elements are external operations executed in a live browser session. Misuse could trigger form submissions, button clicks, navigation, or other consequential UI actions whose effects depend on the target element and page context. This falls under Execute as it drives real browser behavior with side effects that vary widely by argument.

From the tool's definition "performs a mouse action on an element" — triggers browser/UI interactions via Selenium WebDriver

Verdict

interact Rate-limited

interact 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 Mcp Selenium, so you can run agents against it safely.

FAQ

Questions about interact

What does the interact tool do? +

performs a mouse action on an element. It is categorised as a Execute tool in the Mcp Selenium MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on interact? +

Register the Mcp Selenium MCP server in PolicyLayer and add a rule for interact: 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 Mcp Selenium. Nothing to install.

What risk level is interact? +

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

Can I rate-limit interact? +

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

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

interact is provided by the Mcp Selenium MCP server (@angiejones/mcp-selenium). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
