Add a Git remote to a Jujutsu (jj) repository. Parameters: name (Name of the remote to add), url (URL of the remote), repoPath (Optional path to repo root or working directory), cwd (Optional working directory to run the command in).
AI agents use git-remote-add to create or update resources in Jj — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Jj environment.
Adding a remote modifies the repository's configuration by creating a new remote entry pointing to a URL. This is a reversible Write operation (remotes can be removed or updated). While it could facilitate subsequent malicious pushes if pointed to an attacker-controlled URL, the tool itself only modifies local configuration metadata.
From the tool's definition Tool description states it 'Add[s] a Git remote to a Jujutsu (jj) repository', which is a create/modify operation that modifies repository configuration reversibly.

Add a Git remote to a Jujutsu (jj) repository. Parameters: name (Name of the remote to add), url (URL of the remote), repoPath (Optional path to repo root or working directory), cwd (Optional working directory to run the command in). It is categorised as a Write tool in the Jj MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Jj MCP server in PolicyLayer and add a rule for git-remote-add: 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-remote-add is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the git-remote-add 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-remote-add. 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-remote-add 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.
