AI agents call accessibility_audit to retrieve information from Phantom without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
An accessibility audit typically reads UI state and checks for accessibility issues without modifying anything. The name implies a read/inspect operation. However, the description is truncated and uninformative, reducing confidence. Given the context of a mobile testing MCP server, this tool likely inspects the UI tree for accessibility violations and generates a report - a read-only operation.
From the tool's definition Tool name 'accessibility_audit' and truncated description 'Verifie l' - suggests verification/checking functionality

Verifie l. It is categorised as a Read tool in the Phantom MCP Server, which means it retrieves data without modifying state.
Register the Phantom MCP server in PolicyLayer and add a rule for accessibility_audit: 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 Phantom. Nothing to install.
accessibility_audit 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 accessibility_audit 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 accessibility_audit. 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.
accessibility_audit is provided by the Phantom MCP server (nthimpulse/phantom-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
