Show HN: Building an AI Traffic Guardrail(kilasec)

A developer released Kilasec, an AI traffic guardrail proxy built with Claude that applies policies, redacts PII and API keys, sets model destinations and blocks destructive actions before execution, according to a Show HN post. The tool requires a Linux box running the Collector, where policy rules are applied, plus a client app on the machine generating AI traffic that forwards selected requests to it. Kilasec also functions as an MCP server, allowing it to be configured and troubleshot through Claude or other AI tools.

Show HN: An AI traffic guardrail

Building something based on 2 decades of support experience.

It's a guardrail for AI traffic where you can apply policies, redact PII and API keys, set model destinations, catch destructive actions before execution, etc.

The whole thing is built with Claude and can also be configured and troubleshot via Claude/AI tools (it acts as an MCP server).

It acts as a proxy for AI traffic. All you need is a Linux box (the Collector, where policy rules are applied) and a client app installed on the machine generating AI traffic to forward selected requests to it.

Everything is visible in the UI. Lots of customization, with user experience kept in mind throughout.

Happy to answer any questions!
