portpilot

portpilot is a plugin for Claude Code from m4cd4r4/PortPilot. Its manifest loads nothing; the 1 skill, 1 MCP server it bundles cost 66 tokens per session together, scanned A, original, MIT.

A plugin that routes local development-server work through PortPilot, which tracks apps and the ports they use. A development server runs an app on your computer for testing.

In plain words
What is it for?
It is for starting and stopping local development servers through PortPilot rather than unmanaged shell commands.
Why use it?
It helps reuse an app that is already running and avoid starting a second app on a port that is already occupied.

Security

Grade A, and why

portpilot scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it installs

The manifest is a name and a version. 1 skill, 1 MCP server travel with it, and installing the plugin installs all of them — 66 tokens a session between them. Each is measured on its own page, and each can be installed alone.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
