Top 4 Rust prompt-injection Projects
-
Armorer-Guard
Fast local Rust scanner for AI-agent prompt injection, credential leaks, exfiltration, and risky tool calls
Project mention: Agent security needs a local enforcement point, not just logs | dev.to | 2026-06-22Try it in the browser: https://huggingface.co/spaces/armorer-labs/armorer-guard-demo Source: https://github.com/ArmorerLabs/Armorer-Guard

AppSignal
AppSignal knows why the f*#k it crashed. Stop vibe-debugging. Every exception, every backtrace, grouped so you see patterns, not noise.

project-guardian
AI Guardian Firewall — a local, user-space, agent-agnostic firewall that mediates an autonomous AI agent's actions (files, shell, network, services) with a deterministic policy boundary, a tamper-evident audit log, and a human-in-the-loop approval cockpit. No kernel modules. Apache-2.0.

customhouse
Deterministic MCP proxy that blocks money-moving and data-egress tool calls in any agent session that has received untrusted content. No model in the decision path.
Project mention: Blocking prompt injection deterministically costs 40% false positives | news.ycombinator.com | 2026-08-17 -
Project mention: Comment and Control: a GitHub comment hijacks Claude Code in CI | dev.to | 2026-06-02
Three lines of YAML, one secret. No gateway to deploy. The same call works in the Cursor IDE, on a laptop, or in any pipeline via clampd-guard directly.
