vivado_program_device · Vivado Mcp Agent MCP: Risk & Policy

WHAT IT DOES

What vivado_program_device does on Vivado Mcp Agent

AI agents invoke vivado_program_device 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_program_device needs a policy

Programming an FPGA device pushes a bitstream to physical hardware, triggering real-world changes to the device's configuration. This is an irreversible hardware operation mid-session (reprogramming overwrites the current FPGA state), but it doesn't permanently destroy data or files — it reconfigures hardware.

From the tool's definition 'Program FPGA hardware' and 'always requires confirm=true and is excluded from workflows'

Verdict

vivado_program_device Rate-limited

vivado_program_device 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_program_device

What does the vivado_program_device tool do? +

Program FPGA hardware. This always requires confirm=true and is excluded from workflows. 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_program_device? +

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

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

Can I rate-limit vivado_program_device? +

Yes. Add a rate_limit block to the vivado_program_device 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_program_device completely? +

Set action: deny in the PolicyLayer policy for vivado_program_device. 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_program_device? +

vivado_program_device 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.
