列出变更范围内所有提交的作者信息，帮助用户确认自己的Git用户名。支持两种模式： 模式一：分支对比模式（需要 target_branch） 模式二：Commit Hash 模式（需要 from_commit，不需要 target_branch） 使用场景： - 不确定自己的Git用户名时，先查看提交作者列表 - 了解本次迭代有哪些人参与了代码提交
AI agents call list_branch_authors to retrieve information from MCP Code Review Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists commit author information for comparison between branches or commits. It has no side effects, does not modify or delete data, and does not execute external operations. It is a straightforward query operation that gathers metadata about Git history, fitting the 'Read' category. The severity is low because retrieving author information poses minimal security risk.
From the tool's definition 列出变更范围内所有提交的作者信息 (lists author information for all commits in the change range); no modification, deletion, or execution of code implied. The tool purely queries and retrieves Git commit author data.

It is categorised as a Read tool in the MCP Code Review Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Code Review Server MCP server in PolicyLayer and add a rule for list_branch_authors: 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 MCP Code Review Server. Nothing to install.
list_branch_authors 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 list_branch_authors 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 list_branch_authors. 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.
list_branch_authors is provided by the MCP Code Review Server MCP server (xlian-fe/mcp-xl-code-review). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
