WHAT IT DOES

What archive does on Docker

AI agents use archive to create or update resources in Docker, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docker environment.

RISK

Why archive is rated Medium

This tool creates new archive files as output, which constitutes data creation rather than pure read-only retrieval. While the operation is reversible (archives can be deleted), it generates persistent artifacts. The tool does not execute arbitrary code, delete data irreversibly, or move money, making Write the appropriate category.

From the tool's definition Tool description states it 'Creates an archive of files from a git repository' - the verb 'Creates' indicates data generation/modification. The output is a new file ('output file' returned in response).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs archive safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Docker, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For archive, this is the rule to start with:

archive Rate-limited

archive stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about archive

What does the archive tool do? +

Creates an archive of files from a git repository. Supports tar, tar.gz, and zip formats. Returns structured data with success status, format, output file, and treeish. It is categorised as a Write tool in the Docker MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on archive? +

Register the Docker MCP server in PolicyLayer and add a rule for archive: 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 Docker. Nothing to install.

What risk level is archive? +

archive is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit archive? +

Yes. Add a rate_limit block to the archive 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.

How do I block archive completely? +

Set action: deny in the PolicyLayer policy for archive. 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.

What MCP server provides archive? +

archive is provided by the Docker MCP server (@paretools/docker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
