WHAT IT DOES

What config does on Docker

AI agents use config 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 config is rated Medium

The tool can create and modify configuration data through 'set' and 'unset' actions. While these changes are reversible (can be undone by reconfiguring), they affect system/repository state and could be misused to alter authentication credentials, user identity, or other sensitive git settings. This makes it a Write-category tool.

From the tool's definition Tool supports 'set' and 'unset' actions that modify git configuration values at local, global, system, or worktree scope. These are reversible write operations that alter configuration state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs config 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 config, this is the rule to start with:

config Rate-limited

config 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 config

What does the config tool do? +

Manages git configuration values. Supports get, set, list, and unset actions. Operates at local, global, system, or worktree scope. 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 config? +

Register the Docker MCP server in PolicyLayer and add a rule for config: 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 config? +

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

Can I rate-limit config? +

Yes. Add a rate_limit block to the config 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 config completely? +

Set action: deny in the PolicyLayer policy for config. 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 config? +

config 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.
