git_diff_unstaged_tool
AI agents call git_diff_unstaged_tool to retrieve information from MCP Git Commit Generator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
A 'git diff unstaged' operation reads the working directory changes that haven't been staged yet, producing a diff output without modifying any data. This is a read-only operation with minimal blast radius. The empty description lowers confidence, but the name strongly implies a read operation consistent with the sibling tool 'git_diff_tool'.
From the tool's definition Tool name contains 'diff' and 'unstaged', suggesting it reads/displays unstaged changes in a git repository. Description is empty, so confidence is reduced.

Register the MCP Git Commit Generator MCP server in PolicyLayer and add a rule for git_diff_unstaged_tool: 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 Git Commit Generator. Nothing to install.
git_diff_unstaged_tool 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_unstaged_tool 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.
