gets the value of an attribute on an element. Use this to verify element state. Prefer this over screenshots for validation.
AI agents call get_element_attribute to retrieve information from Mcp Selenium without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries DOM element attributes without side effects. It does not create, modify, delete, or execute operations—it only reads state for validation purposes. This is a straightforward Read operation with minimal risk if misused by an AI agent.
From the tool's definition Tool name 'get_element_attribute' and description 'gets the value of an attribute on an element' indicate retrieval of element state without modification. The instruction to 'Prefer this over screenshots for validation' confirms read-only intent.

Register the Mcp Selenium MCP server in PolicyLayer and add a rule for get_element_attribute: 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.
get_element_attribute is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_element_attribute 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 get_element_attribute. 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.
