Flexible tool to fetch vehicle registration counts across any combination of dimensions.
AI agents call get_vahan_metrics 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.
The tool retrieves aggregated metrics from a public vehicle registration database without altering data, executing code, or triggering external operations. Even though the underlying database may contain sensitive personal information, this tool's function is purely to query and return read-only statistical data. Blast radius is minimal—misuse would retrieve information but not modify it or cause financial harm.
From the tool's definition Tool description states 'fetch vehicle registration counts' with no mention of modification, deletion, or execution capabilities. Sibling tool 'run_sql' exists separately, indicating this tool is limited to retrieval.

Register the VAHAN Data MCP Server MCP server in PolicyLayer and add a rule for get_vahan_metrics: 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_vahan_metrics 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_vahan_metrics 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_vahan_metrics. 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.
