WHAT IT DOES

What biome-check does on Test

AI agents invoke biome-check to trigger actions in Test. 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.

RISK

Why biome-check is rated High

The tool executes an external process (Biome linter/formatter) against code files. While it primarily reads and analyzes, it 'runs' a tool that could also apply formatting changes depending on configuration. The word 'Runs' indicates active execution of an external command. Severity is medium as it processes files on the system but primarily in read/analysis mode.

RECOMMENDED RULE

The rule that runs biome-check safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Test, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For biome-check, this is the rule to start with:

biome-check Rate-limited

biome-check 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 biome-check

What does the biome-check tool do? +

Runs Biome check (lint + format) and returns structured diagnostics (file, line, rule, severity, message). It is categorised as a Execute tool in the Test MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on biome-check? +

Register the Test MCP server in PolicyLayer and add a rule for biome-check: 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 Test. Nothing to install.

What risk level is biome-check? +

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

Can I rate-limit biome-check? +

Yes. Add a rate_limit block to the biome-check 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 biome-check completely? +

Set action: deny in the PolicyLayer policy for biome-check. 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 biome-check? +

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