THE RISK

Why cmake needs a policy

CMake operations execute arbitrary build logic defined in CMakeLists.txt files, compile source code, run tests, and install artifacts. While not destructive in the sense of deletion, these are Execute-category actions because they run external processes whose effects depend on the build configuration and arguments. The "install" and "clean" operations modify system state.

From the tool's definition Tool performs "build, test, install, clean" operations on CMake projects. These are code execution actions that compile and install software, with side effects on the filesystem and system state.

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

POLICY

How to control cmake

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

policy.json

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

cmake 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.

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

FAQ

Questions about cmake

What does the cmake tool do? +

CMake build system operations: configure, build, test, list-presets, install, clean. It is categorised as a Execute tool in the Lint MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on cmake? +

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

What risk level is cmake? +

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

Can I rate-limit cmake? +

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

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

cmake is provided by the Lint MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Lint tool call.

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