【通用工具】将代码或文本发送给 Codex 代理进行审查、修改和验证。Codex 将分析代码，执行必要的编辑或命令，并返回修复摘要。每次 Gemini 修改代码后，应该调用此工具获取 Codex 的审查意见。
AI agents call review_code_changes to retrieve information from Codex MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool is a code review and analysis utility. It reads code/text, sends it to an analysis engine, and returns findings. The tool itself does not create, modify, delete, or execute arbitrary external commands—it facilitates static code analysis and review feedback.
From the tool's definition Tool description states it 'sends code or text to Codex agent for review, modification and verification' and 'analyzes code' and 'returns fix summary'. The primary action is analysis and review (read operations).

Register the Codex MCP Server MCP server in PolicyLayer and add a rule for review_code_changes: 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 Codex MCP Server. Nothing to install.
review_code_changes 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_changes 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_changes. 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_changes is provided by the Codex MCP Server MCP server (spongebaby-124/codexreviewermcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
