Fixlane Security

Fixlane tells you whether the developer software on your computer has known security problems, and gives your AI assistant a reviewed procedure to fix each one. It is a plugin for Claude Code, Claude, Codex and ChatGPT, and a remote MCP server that works with any MCP client.

The data is public and read-only. No account, no API key, nothing to install locally: the plugin only connects your assistant to https://fixlane.poparecon.com/mcp.

What it does

Ask "is my computer safe?" or "is my Chrome affected by a known issue?". The security-check skill makes the assistant:

1. list your installed developer software and versions with read-only commands (no install, no sudo, no secrets read);
2. compare the names and versions with the versions that fix known incidents;
3. show you every affected program and its fixed version, and ask before changing anything;
4. follow the returned fix procedure exactly: a read-only check first, then the fix. Phones get manual steps only.

Tools

Tool	Use
check_software	A program, package or CVE id: known incidents, severity, whether it is exploited, the fixed version.
get_fix_prompt	An incident id and the operating system: the reviewed fix procedure (agent prompt for macOS, Windows, Linux; manual steps for iOS, Android).
latest_incidents	The newest incidents, optionally for one operating system and since a date.
get_digest	One fix prompt for everything to update now on a desktop system.
check_inventory	Up to 50 installed programs with versions: which are affected, not affected or unknown.

All five tools are read-only.

The Fixlane server stores nothing about your questions: no query text, no software names, no IP address. Names and versions you send to check_inventory are used only to answer the call. A proxy or CDN in front of the server may handle connection data under its own policy. The full policy is at https://fixlane.poparecon.com/privacy; terms are at https://fixlane.poparecon.com/terms.
