vite-build · Python MCP: Risk & Policy

WHAT IT DOES

What vite-build does on Python

AI agents invoke vite-build to trigger actions in Python. 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 vite-build needs a policy

This tool triggers execution of an external build tool (Vite) whose effects depend on the project configuration and code being built. While not destructive by itself, it executes arbitrary code through the build process and generates files, making it an Execute category risk.

From the tool's definition Tool runs Vite production build, an external build process that compiles code and generates output artifacts.

Verdict

vite-build Rate-limited

vite-build 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Python, so you can run agents against it safely.

FAQ

Questions about vite-build

What does the vite-build tool do? +

Runs Vite production build and returns structured output files with sizes. It is categorised as a Execute tool in the Python MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on vite-build? +

Register the Python MCP server in PolicyLayer and add a rule for vite-build: 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 Python. Nothing to install.

What risk level is vite-build? +

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

Can I rate-limit vite-build? +

Yes. Add a rate_limit block to the vite-build 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 vite-build completely? +

Set action: deny in the PolicyLayer policy for vite-build. 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 vite-build? +

vite-build is provided by the Python MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
