Select an option from a <select> dropdown by its value.
AI agents invoke browserbeam_select to trigger actions in Browserbeam 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.
Selecting a dropdown option is a browser action that modifies the state of a web page form element. This is an Execute-class operation because it triggers an external operation (browser interaction) whose effects depend on the arguments passed (which option is selected).
From the tool's definition 'Select an option from a <select> dropdown by its value' — triggers a browser UI interaction that can change form state and potentially submit data or trigger downstream actions.
Attacks that exploit this kind of access
Select an option from a <select> dropdown by its value. It is categorised as a Execute tool in the Browserbeam MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Browserbeam MCP Server MCP server in PolicyLayer and add a rule for browserbeam_select: 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 Browserbeam MCP Server. Nothing to install.
browserbeam_select is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the browserbeam_select 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.
Set action: deny in the PolicyLayer policy for browserbeam_select. 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.
browserbeam_select is provided by the Browserbeam MCP Server MCP server (nyku/browserbeam-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
browserbeam_select is one line of Browserbeam MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
