【次要工具】审查单个文件的内容。适用于改动仅在单个或两个文件内的情况。Codex 将读取文件并根据变更描述提供审查建议。
AI agents call review_file 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 performs code review analysis—examining and querying file content to generate suggestions. It retrieves data (file contents) and produces advisory output with no side effects, reversible modifications, or command execution. This is a read-only analysis operation typical of linting and review tools.
From the tool's definition Tool description states it 'reads the file' (读取文件) and 'provides review suggestions' (提供审查建议) based on changes. The name 'review_file' and description emphasize analysis and recommendations without modification.

【次要工具】审查单个文件的内容。适用于改动仅在单个或两个文件内的情况。Codex 将读取文件并根据变更描述提供审查建议。. It is categorised as a Read tool in the Codex MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Codex MCP Server MCP server in PolicyLayer and add a rule for review_file: 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_file 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_file 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_file. 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_file 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.
