AI agents call xdc_lint 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.
Lint tools generally read and analyze files without modifying them. XDC lint would check constraint files for errors or warnings. However, the description is empty, so there is uncertainty — it could potentially write reports or trigger execution. Confidence is low due to missing description. Severity is medium because misuse in an FPGA development context could affect design correctness.
From the tool's definition Tool name 'xdc_lint' suggests static analysis/linting of XDC (Xilinx Design Constraints) files, which is typically a read/analysis operation.
Documented attack patterns abuse exactly the kind of access xdc_lint 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 xdc_lint:
{
"version": "1",
"default": "deny",
"tools": {
"xdc_lint": {}
}
}xdc_lint is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

xdc_lint. 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 xdc_lint: 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.
xdc_lint 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 xdc_lint 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 xdc_lint. 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.
xdc_lint 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.
