AI agents call apg_get_example to retrieve information from Accessibility without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool's function is to retrieve and display reference implementations and example source code from the WAI-ARIA Authoring Practices Guide. It returns static documentation artifacts (HTML, CSS, JavaScript examples) for the purpose of education and reference. There are no side effects, no data modification, no code execution triggered by the tool itself, and no destructive operations.
From the tool's definition Tool retrieves and provides 'Official example source for one APG demo: HTML plus linked CSS/JS' — it fetches documentation and code examples without modifying, deleting, or executing arbitrary code.
Attacks that exploit this kind of access
Official example source for one APG demo: HTML plus linked CSS/JS (and placeholders for binary assets). It is categorised as a Read tool in the Accessibility MCP Server, which means it retrieves data without modifying state.
Register the Accessibility MCP server in PolicyLayer and add a rule for apg_get_example: 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 Accessibility. Nothing to install.
apg_get_example 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 apg_get_example 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 apg_get_example. 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.
apg_get_example is provided by the Accessibility MCP server (nicolasgalvez/accessibility-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
