agentshield vs hol-guard
agentshield: AgentShield is an offline, high-performance Rust security engine designed to detect risky behaviors in AI agent extensions and MCP servers before deployment. It identifies vulnerabilities like command injection, credential exfiltration, and prompt injection across various AI frameworks.; hol-guard: HOL Guard acts as an antivirus for AI harnesses, intercepting tool actions to protect against file changes and network contact. It also includes `plugin-scanner`, a complementary tool for linting and verifying AI plugins and packages in CI environments before release, ensuring quality and security.

TL;DR
agentshieldSecurity & Safety · ★ 21
Scan AI agent extensions and tool repositories (e.g., for Claude Desktop, OpenAI Agents SDK) before deployment or integration.
hol-guardSecurity & Safety · ★ 969
When to choose:
- You run Codex, Claude Code, Copilot CLI, Cursor or similar and want a check before new or changed tools run.
- You maintain plugins, skills or MCP servers and want a CI step such as `plugin-scanner verify .`.
- You want local receipts of what was approved or blocked.
When to skip:
- You need a clear licence in GitHub's metadata today; our data shows none detected.
- You want a minimal tool: the README covers a large surface of commands and integrations.
- You cannot accept extra approval prompts in your agent workflow.
