WHAT IT DOES

What build_image does on 1Panel MCP Server

AI agents invoke build_image to trigger actions in 1Panel MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why build_image is rated High

Building a Docker image executes a build process with side effects that depend on the provided arguments (Dockerfile, build context, etc.). While not immediately destructive or financial, it triggers external operations and consumes resources. This falls under Execute rather than Write because image builds are operational procedures that run code/processes, not simple data creation.

From the tool's definition Tool is named 'build_image' and described as 'Build image' in the context of a server infrastructure management system that handles Docker containers and application deployment.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs build_image safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 1Panel MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For build_image, this is the rule to start with:

build_image Rate-limited

build_image stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "build_image": {
      "limits": [
        {
          "counter": "build_image_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect 1Panel MCP Server, apply this rule, and every build_image call is checked against it from then on.

FAQ

Questions about build_image

What does the build_image tool do? +

build_image is a execute tool on the 1Panel MCP Server MCP server. It is categorised as a Execute tool in the 1Panel MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on build_image? +

Register the 1Panel MCP Server MCP server in PolicyLayer and add a rule for build_image: 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 1Panel MCP Server. Nothing to install.

What risk level is build_image? +

build_image is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit build_image? +

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

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

build_image is provided by the 1Panel MCP Server MCP server (eaveluo/1panel-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
