HOL Guard: Open-Source Antivirus for AI Agents

| | Stop risky AI actions before they compromise your machine. HOL Guard is a local-first security layer for AI agents, tools, plugins, skills, MCP servers, and package installs.

Install HOL Guard Read the documentation PyPI Package (hol-guard) Report an Issue | | :--- | :--- |

HOL Guard reviews agent actions before they run: shell commands, file access, package installs, and MCP tool calls. It detects secret exposure, destructive operations, prompt injection, and supply-chain risks, then allows, blocks, or requests approval according to your policy.

Run it locally without an account. Use the CLI and local dashboard to manage protection, resolve approvals, and inspect decision history. Optional Guard Cloud adds shared history, team policy, and fleet management.

Get started · Supported agents · Plugin scanner · Documentation · Contribute an extension · Contribute an adapter · Development

Install HOL Guard

Requires Python 3.10 or newer, pipx, and a matching native runtime. Check the platform support and Windows ARM64 setup notes before installing.

pipx install hol-guard

hol-guard init

The first-run wizard discovers supported agents and walks you through protection setup. It asks before each setup change, including opening the dashboard, installing agent integrations, and connecting optional cloud services.

Check your installation:

hol-guard --version

hol-guard status

To update an existing installation:

hol-guard update

For manual setup, see the installation guide. Annotated release notes with upgrade context live at hol.org/guard/releases; raw releases and prereleases are on the GitHub releases page.

What HOL Guard Protects

Surface	Protection
Shell commands and file access	Reviews destructive operations, sensitive file access, credential exposure, and suspicious outbound commands.
Package installs	Evaluates supported package-manager operations against supply-chain intelligence before installation.
Plugins, skills, and agent configuration	Inventories local artifacts and reviews new or changed tools before launch.
MCP servers and tools	Inspects server configuration and reviews tool calls through supported hooks and managed proxies.
Prompts and tool results	Screens supported events for prompt injection and sensitive content.
Approvals and evidence	Routes decisions to native prompts or the approval center, and records local receipts for review.

Guard connects through native agent hooks, managed MCP proxies, and launch integrations. Coverage depends on the events each agent exposes; the support matrix documents enforcement, approval delivery, and failure behavior per integration.

Supported AI Agents

Codex, Claude Code, GitHub Copilot CLI, Cursor, Cline, Gemini CLI, Grok, Hermes, Kimi Code, Pi, oh-my-pi, OpenClaw, OpenCode, Antigravity, ZCode, and Devin. Paseo is supported through these native provider integrations, with per-provider coverage.

For example, to set up Codex explicitly:

hol-guard install codex

hol-guard run codex --dry-run hol-guard run codex

The dry run records the current artifact state before launch. For Codex, Guard installs native pre-tool hooks and refuses a managed launch if those hooks are missing or disabled.

Agent support matrix · Troubleshooting

Everyday Use

Task	Command
Check protection status	`hol-guard status`
Diagnose an agent integration	`hol-guard doctor codex`
Inspect changes before launch	`hol-guard diff codex`
Review pending approvals	`hol-guard approvals`
Approve or deny a request	`hol-guard approvals approve` / `hol-guard approvals deny`
Read decision history	`hol-guard receipts`
List tracked artifacts	`hol-guard inventory`
Export an AI bill of materials	`hol-guard abom --format json`
Scan workspace dependencies	`hol-guard supply-chain scan`
Connect optional cloud sync	`hol-guard connect`

Understand a paused command

Inspect the command's classification and matching rules:

hol-guard command test 'rm -rf ./build'

hol-guard command explain 'git clean -ndx' hol-guard command extensions command.git --json

command test and command explain inspect the command without executing it or creating an approval. Use hol-guard approvals to resolve a pending request and hol-guard receipts to review the recorded decision.

The Extension directory lists command coverage generated from the Rust-compiled catalog. External contributions require explicit opt-in; required core protections remain enabled. To add coverage, follow the Extension contribution guide.

Check a package

hol-guard supply-chain sync

hol-guard supply-chain scan hol-guard supply-chain explain minimist@1.2.5 --ecosystem npm

The package verdict includes the available advisory evidence and ecosystem coverage. See the get-started guide for package-manager interception and the remediation guide for handling false positives.

Plugin Scanner

This repository also ships plugin-scanner, a CLI for maintainers who want security and quality checks before publishing agent plugins, skills, and MCP integrations.

pipx install plugin-scanner

plugin-scanner scan . plugin-scanner lint . plugin-scanner verify .

Command	Purpose
`scan`	Security findings and a quality report across detected package surfaces.
`lint`	Rule-level authoring feedback.
`verify`	Install-surface and runtime readiness checks.
`submit`	A submission artifact for one plugin package.
`doctor`	Component diagnostics and troubleshooting bundles.

The scanner detects Codex, Claude Code, DeepSeek Harness, Gemini CLI, Kimi Code, and OpenCode package formats. Use plugin-scanner --list-ecosystems to list them or --ecosystem to select one. At a Codex marketplace root, it discovers local plugin entries automatically.

Checks cover manifests, secrets, MCP transport and command configuration, approval defaults, skills, dependency lockfiles, and GitHub Actions permissions. Optional Cisco integrations add skill and MCP analysis. Reports support text, JSON, Markdown, and SARIF.

plugin-scanner scan . --format sarif --output plugin-scanner.sarif

plugin-scanner scan . --fail-on-severity high

Quality grades use the checks applicable to each package. Trust scoring has separate provenance and weights; see the skill, MCP, and plugin scoring references.

Package a plugin for every runtime

hol-guard plugin is the Plugin Kit. Point it at one plugin source, such as a Claude Code plugin, Codex plugin, Gemini CLI extension, MCP Registry server.json or a folder of skills, and it checks the source and writes a ready-to-load copy for each agent runtime that can use it. It runs locally, reads only the folder you name and makes no network calls.

hol-guard plugin check            # what marketplaces and runtime loaders would reject

hol-guard plugin package # writes dist/hol-plugin/ / for each runtime hol-guard plugin convert --to agent-plugins # Agent Plugins 1.0 package, checked against the spec hol-guard plugin links # install commands per runtime, plus listing links hol-guard plugin card # draft .well-known plugin card as JSON hol-guard plugin init --name my-plugin # scaffold a new plugin in an empty folder

Runtimes: claude-code, codex, gemini-cli, cursor, vscode, opencode, mcp-registry, agent-skills and agent-plugins. See the Plugin Kit guide.
