AI agents call set_wave_zoom as a supporting operation in Vivado workflows.
The name suggests adjusting zoom level on a waveform viewer, which is a UI/display-only operation with no data modification, execution, or destructive effects. However, since the description is empty, confidence is low. Given the context of Vivado EDA tooling, this is most likely a read/display adjustment with minimal blast radius.
From the tool's definition Tool name is 'set_wave_zoom'; description is empty or uninformative.
Documented attack patterns abuse exactly the kind of access set_wave_zoom 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 set_wave_zoom:
{
"version": "1",
"default": "deny",
"tools": {
"set_wave_zoom": {
"limits": [
{
"counter": "set_wave_zoom_rate",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
}
}set_wave_zoom gets a rate cap, and everything else on the server is denied unless you say otherwise.

set_wave_zoom. It is categorised as a Other tool in the Vivado MCP Server, which means it performs auxiliary operations.
Register the Vivado MCP server in PolicyLayer and add a rule for set_wave_zoom: 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.
set_wave_zoom is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the set_wave_zoom 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 set_wave_zoom. 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.
set_wave_zoom 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.
