AI agents call get-aria-version to retrieve information from Aria without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves read-only information about ARIA specification version and metadata. It performs a simple lookup with no side effects, no data modification, no code execution, and no destructive operations. It is purely informational and poses minimal risk if invoked by an AI agent.
From the tool's definition Tool name 'get-aria-version' and description 'Get information about the ARIA specification version and metadata' indicate a query operation that retrieves static specification metadata without modifying any data or triggering external operations.
Attacks that exploit this kind of access
Get information about the ARIA specification version and metadata. It is categorised as a Read tool in the Aria MCP Server, which means it retrieves data without modifying state.
Register the Aria MCP server in PolicyLayer and add a rule for get-aria-version: 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 Aria. Nothing to install.
get-aria-version 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-aria-version 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-aria-version. 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.
get-aria-version is provided by the Aria MCP server (joe-watkins/aria-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
