Generates the text diff for a Git merge commit against its first parent within a specified local repository.
AI agents call git_merge_diff to retrieve information from Git Stuff Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads repository data and produces a diff output. It does not modify, delete, or execute anything — it purely retrieves and displays differences between commits. No side effects are described.

Attacks that exploit this kind of access
Generates the text diff for a Git merge commit against its first parent within a specified local repository. It is categorised as a Read tool in the Git Stuff Server MCP Server, which means it retrieves data without modifying state.
Register the Git Stuff Server MCP server in PolicyLayer and add a rule for git_merge_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 Stuff Server. Nothing to install.
git_merge_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_merge_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_merge_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_merge_diff is provided by the Git Stuff Server MCP server (skurekjakub/gitstuffserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
