查看代码改动对比 (git diff)
AI agents call git_diff to retrieve information from Git Commit MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
git diff only reads and displays differences between file states; it has no side effects and does not modify any data.

Attacks that exploit this kind of access
查看代码改动对比 (git diff). It is categorised as a Read tool in the Git Commit MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Git Commit MCP Server MCP server in PolicyLayer and add a rule for git_diff: 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 Git Commit MCP Server. Nothing to install.
git_diff 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 git_diff 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 git_diff. 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.
git_diff is provided by the Git Commit MCP Server MCP server (lenslp/git-commit-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
