compose-build

Builds Docker Compose service images and returns structured per-service build status.

Accepts file system path (path); High parameter count (14 properties)

Part of the Docker MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

@paretools/docker Execute Risk 4/5

AI agents invoke compose-build to trigger processes or run actions in Docker. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

compose-build can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

compose-build is one of the high-risk operations in Docker. For the full severity-focused view — only the high-risk tools with their recommended policies — see the breakdown for this server, or browse all high-risk tools across every MCP server.

What does the compose-build tool do? +

Builds Docker Compose service images and returns structured per-service build status.. It is categorised as a Execute tool in the Docker MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on compose-build? +

Add a rule in your Intercept YAML policy under the tools section for compose-build. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Docker MCP server.

What risk level is compose-build? +

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

Can I rate-limit compose-build? +

Yes. Add a rate_limit block to the compose-build rule in your Intercept 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 compose-build completely? +

Set action: deny in the Intercept policy for compose-build. 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 compose-build? +

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