review_code
AI agents call review_code to retrieve information from Best Practices MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Code review capabilities in this context mean analyzing code against best practices guidelines and returning improvement suggestions—a read-only operation that retrieves or evaluates data without side effects. There is no indication the tool executes, modifies, or deletes code.
From the tool's definition Tool named 'review_code' on a Best Practices MCP Server alongside sibling tools like 'search_best_practices', 'get_examples_tool', and 'suggest_improvements'.

review_code. It is categorised as a Read tool in the Best Practices MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Best Practices MCP Server MCP server in PolicyLayer and add a rule for review_code: 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 Best Practices MCP Server. Nothing to install.
review_code is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the review_code 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.
Set action: deny in the PolicyLayer policy for review_code. 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.
review_code is provided by the Best Practices MCP Server MCP server (n-ochs/best-practice-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
