Show the underlying Git directory of a repository using the Git backend in Jujutsu (jj). Useful for finding the .git directory location. Parameters: repoPath (Optional path to repo root or working directory), cwd (Optional working directory to run the command in).
AI agents call git-root to retrieve information from Jj without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and displays the path to the Git directory. It has no side effects, does not modify any data, and simply returns filesystem location information.

Show the underlying Git directory of a repository using the Git backend in Jujutsu (jj). Useful for finding the .git directory location. Parameters: repoPath (Optional path to repo root or working directory), cwd (Optional working directory to run the command in). It is categorised as a Read tool in the Jj MCP Server, which means it retrieves data without modifying state.
Register the Jj MCP server in PolicyLayer and add a rule for git-root: 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 Jj. Nothing to install.
git-root 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-root 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-root. 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-root is provided by the Jj MCP server (jj-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
