AI agents call get_io_report to retrieve information from Vivado without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool fetches and returns information about IO pins in a structured format. It is a diagnostic/reporting function that reads data from the Vivado project state without modifying, executing, or deleting anything. The 'get_' prefix and read-only nature of IO reporting confirm Read category classification. Severity is low because retrieving pin information poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'get_io_report' and description 'retrieves structured IO pin report (JSON)' indicate a query/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_io_report gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Vivado, and nothing reaches the server without passing your rules. This is the rule we recommend for get_io_report:
{
"version": "1",
"default": "deny",
"tools": {
"get_io_report": {}
}
}get_io_report is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取结构化 IO 引脚报告（JSON）。. It is categorised as a Read tool in the Vivado MCP Server, which means it retrieves data without modifying state.
Register the Vivado MCP server in PolicyLayer and add a rule for get_io_report: 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 Vivado. Nothing to install.
get_io_report 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_io_report 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_io_report. 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_io_report is provided by the Vivado MCP server (mapleleavessssssss-wq/vivado-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Vivado, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
