What create_build does on Komodo

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

Why create_build needs a policy

This tool creates or modifies data (a build configuration) in a reversible manner. It does not execute arbitrary code, delete data irreversibly, or move money. While build configurations could theoretically trigger subsequent execution if activated, the tool itself only creates the configuration artifact.

From the tool's definition Tool name 'create_build' and description 'Create a new build configuration' indicate reversible data creation. The tool creates a new build configuration resource within the Komodo DevOps platform.

Documented attack patterns abuse exactly the kind of access create_build gives an agent:

How to control create_build

PolicyLayer is an MCP gateway — it sits between your AI agents and Komodo, and nothing reaches the server without passing your rules. This is the rule we recommend for create_build:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_build": {
      "limits": [
        {
          "counter": "create_build_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_build 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.

  1. Create a free account and register Komodo — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about create_build

What does the create_build tool do? +

Create a new build configuration. It is categorised as a Write tool in the Komodo MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_build? +

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

What risk level is create_build? +

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

Can I rate-limit create_build? +

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

Set action: deny in the PolicyLayer policy for create_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 create_build? +

create_build is provided by the Komodo MCP server (myrikld/komodo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Komodo tool call.

Start from Komodo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
