Identify top values in a dimension (e.g., top makers) based on registration volume.
AI agents call get_top_performers to retrieve information from VAHAN Data MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs aggregation and ranking of public vehicle registration statistics—a read-only analytical operation. It retrieves insights from the VAHAN database without side effects, reversible changes, or external command execution. The low severity reflects minimal harm potential even if misused by an AI agent, as it only returns sorted subsets of already-public registration data.
From the tool's definition Tool name 'get_top_performers' and description 'Identify top values in a dimension...based on registration volume' indicate a query operation that retrieves and ranks existing data without modification, deletion, or code execution.
Attacks that exploit this kind of access
Identify top values in a dimension (e.g., top makers) based on registration volume. It is categorised as a Read tool in the VAHAN Data MCP Server MCP Server, which means it retrieves data without modifying state.
Register the VAHAN Data MCP Server MCP server in PolicyLayer and add a rule for get_top_performers: 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 VAHAN Data MCP Server. Nothing to install.
get_top_performers 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_top_performers 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_top_performers. 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_top_performers is provided by the VAHAN Data MCP Server MCP server (shubhamgrg04/vahanmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
