vivado_workflow_run · Vivado Mcp Agent MCP: Risk & Policy

WHAT IT DOES

What vivado_workflow_run does on Vivado Mcp Agent

AI agents invoke vivado_workflow_run to trigger actions in Vivado Mcp Agent. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why vivado_workflow_run needs a policy

This tool triggers deterministic but non-reversible transformations of FPGA designs through multiple execution stages (validate, simulate, synthesize, implement, generate bitstream). While safety gates limit misuse, the execution of synthesis and implementation with arbitrary design files can produce unexpected hardware behavior or resource exhaustion.

From the tool's definition Tool executes a multi-stage workflow including simulation, synthesis, implementation, and bitstream generation. The description uses 'run' and 'workflow' indicating code/command execution whose effects depend on the design arguments and gating configuration.

Verdict

vivado_workflow_run Rate-limited

vivado_workflow_run stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about vivado_workflow_run

What does the vivado_workflow_run tool do? +

Run validate/create_project/sim/synth/impl/drc/cdc/bitstream workflow with safety gates. It is categorised as a Execute tool in the Vivado Mcp Agent MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on vivado_workflow_run? +

Register the Vivado Mcp Agent MCP server in PolicyLayer and add a rule for vivado_workflow_run: 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_workflow_run? +

vivado_workflow_run is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit vivado_workflow_run? +

Yes. Add a rate_limit block to the vivado_workflow_run 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_workflow_run completely? +

Set action: deny in the PolicyLayer policy for vivado_workflow_run. 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_workflow_run? +

vivado_workflow_run 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.
