golangci-lint · Python MCP: Risk & Policy

WHAT IT DOES

What golangci-lint does on Python

AI agents invoke golangci-lint to trigger actions in Python. 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.

WHY IT NEEDS A POLICY

Why golangci-lint needs a policy

The tool executes an external linter process (golangci-lint) against code. While it is read-like in intent (static analysis), it actually runs an external command/process whose effects depend on the arguments passed. No data is destroyed or written, but it executes an external tool, placing it in the Execute category.

Verdict

golangci-lint Rate-limited

golangci-lint 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Python, so you can run agents against it safely.

FAQ

Questions about golangci-lint

What does the golangci-lint tool do? +

Runs golangci-lint and returns structured lint diagnostics (file, line, linter, severity, message). It is categorised as a Execute tool in the Python MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on golangci-lint? +

Register the Python MCP server in PolicyLayer and add a rule for golangci-lint: 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 Python. Nothing to install.

What risk level is golangci-lint? +

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

Can I rate-limit golangci-lint? +

Yes. Add a rate_limit block to the golangci-lint 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 golangci-lint completely? +

Set action: deny in the PolicyLayer policy for golangci-lint. 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 golangci-lint? +

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