AI agents call compare_xci 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.
The tool performs data retrieval and analysis (comparison) of two configuration files. No creation, modification, deletion, code execution, or financial operations are involved. This is a purely informational read operation typical of FPGA development diagnostics.
From the tool's definition Tool compares/analyzes two XCI files for IP configuration differences ('对比两个 XCI 文件的 IP 配置差异' - compare two XCI files' IP configuration differences). XCI files are Xilinx IP configuration files.
Documented attack patterns abuse exactly the kind of access compare_xci 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 compare_xci:
{
"version": "1",
"default": "deny",
"tools": {
"compare_xci": {}
}
}compare_xci is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

对比两个 XCI 文件的 IP 配置差异。. 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 compare_xci: 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.
compare_xci 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 compare_xci 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 compare_xci. 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.
compare_xci 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.
