AI agents call file-list 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 retrieves and queries repository file structure at a specific revision without modifying, deleting, or executing any operations. It has no side effects and falls squarely into the Read category. Severity is low because listing files poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'file-list' and description states it 'List files in a revision of a Jujutsu (jj) repository' and is 'Useful for exploring the repository contents'. Parameters include optional revision, paths filter, and repo path, all for querying purposes.

List files in a revision of a Jujutsu (jj) repository. Useful for exploring the repository contents at a specific point in history. Parameters: revision (Optional revision to list, defaults to working copy), paths (Optional paths to filter by), 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 file-list: 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.
file-list 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 file-list 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 file-list. 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.
file-list 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.
