WHAT IT DOES

What vivado_generate_design_spec does on Vivado Mcp Agent

AI agents use vivado_generate_design_spec to create or update resources in Vivado Mcp Agent — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Vivado Mcp Agent environment.

WHY IT NEEDS A POLICY

Why vivado_generate_design_spec needs a policy

This tool creates new specification data (design_spec.yaml) from input requirements, making it a Write operation. It's reversible—the generated file can be modified or deleted. Severity is medium because incorrect generated specifications could cause downstream design issues in FPGA workflows, but the impact is limited to the specification layer rather than hardware execution.

From the tool's definition Tool generates and creates a design_spec.yaml file from requirements. The verb 'Generate' combined with creating specification files indicates data creation. The description states it produces a 'design_spec.yaml body', which is file/data creation output.

FAQ

Questions about vivado_generate_design_spec

What does the vivado_generate_design_spec tool do? +

Generate a deterministic design_spec.yaml body from natural-language requirements. It is categorised as a Write tool in the Vivado Mcp Agent MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on vivado_generate_design_spec? +

Register the Vivado Mcp Agent MCP server in PolicyLayer and add a rule for vivado_generate_design_spec: 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 Mcp Agent. Nothing to install.

What risk level is vivado_generate_design_spec? +

vivado_generate_design_spec is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit vivado_generate_design_spec? +

Yes. Add a rate_limit block to the vivado_generate_design_spec 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.

How do I block vivado_generate_design_spec completely? +

Set action: deny in the PolicyLayer policy for vivado_generate_design_spec. 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.

What MCP server provides vivado_generate_design_spec? +

vivado_generate_design_spec is provided by the Vivado Mcp Agent MCP server (wangyuxin0707/vivado-mcp-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
