Runs cargo clippy and returns structured lint diagnostics.
AI agents invoke clippy to trigger actions in Make. 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.
The tool runs an external command (cargo clippy) on the host system. While clippy is a read-only linter in typical usage, it executes code analysis tooling as a subprocess with potential side effects depending on arguments (e.g., --fix). Execution of external processes falls under Execute. Severity is medium since clippy itself is generally safe but running arbitrary cargo commands has a moderate blast radius.
From the tool's definition 'Runs cargo clippy' — executes an external build/lint tool process
Documented attack patterns abuse exactly the kind of access clippy gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Make, and nothing reaches the server without passing your rules. This is the rule we recommend for clippy:
{
"version": "1",
"default": "deny",
"tools": {
"clippy": {
"limits": [
{
"counter": "clippy_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}clippy 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.

Runs cargo clippy and returns structured lint diagnostics. It is categorised as a Execute tool in the Make MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Make MCP server in PolicyLayer and add a rule for clippy: 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 Make. Nothing to install.
clippy is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the clippy 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.
Set action: deny in the PolicyLayer policy for clippy. 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.
clippy is provided by the Make MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Make, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
