验证 IO 引脚分配：比对 XDC 约束与实际布局。
AI agents call verify_io_placement_tool 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 performs verification and comparison of IO pin placement by checking XDC constraints against actual layout. It retrieves and analyzes data without creating, modifying, deleting, or executing external operations. The action is purely informational—comparing two data sources to validate correctness. This is characteristic of Read category tools (get, verify, check, compare).
From the tool's definition Tool name contains 'verify' and description states '验证 IO 引脚分配：比对 XDC 约束与实际布局' (verify IO pin allocation: compare XDC constraints with actual layout). This is a comparison/validation operation that checks constraints against layout without modifying either.
Documented attack patterns abuse exactly the kind of access verify_io_placement_tool 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 verify_io_placement_tool:
{
"version": "1",
"default": "deny",
"tools": {
"verify_io_placement_tool": {}
}
}verify_io_placement_tool is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Vivado MCP server in PolicyLayer and add a rule for verify_io_placement_tool: 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.
verify_io_placement_tool 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 verify_io_placement_tool 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 verify_io_placement_tool. 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.
verify_io_placement_tool 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.
