Descripción del creador (original en inglés)
Security tools for coding agents: dependency advisory audits and evidence for remediation.
Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.

Comparado con todos los servidores activos de esta categoría en el registro. Las estrellas solo cuentan cuando quien lo publica es dueño del repo.
Superó 1 de 1 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.
El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.
Se ejecuta en la nube del creador. Te conectas por internet sin instalar nada, pero lo que envías pasa por los servidores del creador.
El repo de GitHub cambió por última vez –, y la última versión (0.7.0) llegó al registro hace 6 días.
Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. Se conecta por URL, así que también funcionan las apps que aceptan servidores MCP remotos, como ChatGPT en modo desarrollador.

Security tools your AI agent can discover, call and verify.
Offense is a product by [Offense Research, Inc.](https://offenseresearch.com). Open-source software, optional paid hosting.
Give Pi, OMP, Hermes, Codex, Claude Code, Crush or another coding agent the tools to audit dependencies, inspect source and workflows, and test a proposed fix. Offense returns structured security evidence through CLI, MCP and HTTP. Your agent reads that evidence, investigates your code, makes authorized changes and runs your tests—with its existing model, repository access and permissions.

Enter your GitHub repository and base branch. The installer opens GitHub's prefilled workflow editor; review the file, choose Create a new branch, then open a pull request. No Offense account, API key or GitHub token is required. Offense prepares the link; you create and approve the PR on GitHub.
The starter adds free npm/pnpm dependency audits on pull requests using pinned, read-only GitHub Actions. It never installs or runs your app, edits code or calls paid Offense tools. Dependency metadata goes to OSV/npm; reports are retained as GitHub artifacts for seven days. Advisories are report-only; coverage warnings and scan errors fail the check. GitHub Actions usage limits and charges still apply. This is a dependency check, not the full tool catalog.
Review the template · Manual installation, privacy and updates
Paste this into your coding agent in the project you want to check:
Set up Offense for this project. Read the installation instructions at
https://github.com/offense-research/offense#install-the-offensesh-agent-skill and review the skill at https://raw.githubusercontent.com/offense-research/offense/main/.agents/skills/scanning-with-offense/SKILL.md
Reuse an existing reviewed Offense checkout or connection if available. Otherwise inspect the public source before using its helpers. Install the skill in this agent's project-local skill directory, preserving custom files and other agent settings. Tell me if a new session or project trust is needed.
Run only the offline dependency-input preview. Show the selected lockfiles, unsupported inputs and which execution mode would perform the real audit. Do not upload data, run a paid scan, install the target project's dependencies, edit application code, commit or push.
The first success is a real preview and an explicit scope, not “installed” without a command result. The agent needs terminal/filesystem access and Node; copying a skill does not give a chat-only client those capabilities. If it cannot read GitHub pages, use the raw skill URL or a reviewed local checkout.
Already configured? Ask: “Use Offense to check my app for security problems, explain the findings and consequences, and help me decide what to fix.” Offense infers relevant checks from the project, reports missing coverage, and asks only for the inputs or authorization those checks need. Assessment alone does not authorize application edits or paid calls. Narrow dependency and local-only requests keep their scope.
Start with one of the task prompts below. Prefer manual setup? Use the per-agent instructions.
The native plugin is built from the same maintained skill and CLI in this repo. To try a local checkout with Codex:
codex plugin marketplace add /absolute/path/to/offense
codex plugin add offense@offense
Start a new Codex session, then ask $offense:offense to check your app and explain the findings. Installing does not log in, scan, buy credit or register MCP. The plugin reuses existing connections or its bundled CLI. Codex owns updates; credentials stay in the CLI's private configuration. If you already installed a manual Offense skill, choose which entry point to keep; customized skills and project instructions are never removed automatically.
Once these files are published on the repository's default branch, the intended remote registration is codex plugin marketplace add offense-research/offense, followed by codex plugin add offense@offense. The local path has been smoke tested; the remote command requires verification against that published ref. Public OpenAI directory listing is a separate submission, not part of this build.
Put the examples on offense.sh to work. Each recipe includes an agent prompt, prerequisites, commands, approval boundaries and the evidence to return. Start with a single reviewed run before adding recurring automation.
| Build or run | Recipe |
|---|---|
| Your dependency bot / a pre-release audit | Audit dependencies and verify reviewed upgrades |
| Your first reviewer | Review a PR with source evidence |
| Your secrets guard | Check staged or tracked contents without confusing the snapshots |
| A SQL-injection review | Trace request input, parameterize and test |
| Your CI reviewer | Review Actions YAML without executing workflows |
| Your API tester | Exercise a disposable local API with bounded requests |
These are recipes for your agent, not installed schedules, hooks or bots. Local scanners need their pinned engines; hosted Gitleaks needs availability, upload approval and a spending ceiling. See the shared setup and limits.
Offense is not an autonomous permission grant. A finding is not a confirmed exploit, an advisory match is not proof of reachability, and a partial scan is not a clean bill of health. Your agent remains responsible for reviewing changes and obtaining authorization before active testing, paid calls or publication.

| Mode | Best for | Requirements | Execution and cost |
|---|---|---|---|
| Local dependency engine | Auditing a project from your terminal or coding agent | Node.js 24+, npm; no Docker or Offense account for dependency analysis | Runs on your machine; queries public OSV/npm metadata; no Offense usage charge |
| Self-hosted platform | Running your own API, MCP endpoint and isolated source scanners | Linux amd64, Node.js 24+, npm, Git and Docker Engine | Your infrastructure; dependency audits, Opengrep and Zizmor enabled; Offense billing disabled |
| Hosted service | Using managed tool execution without operating the scanner infrastructure | An Offense account for authenticated tools | Runs on the service; enabled paid tools use quoted prepaid credit |
The local engine and self-hosted profile do not require an Offense subscription or model-provider key. Advisory lookup still needs network access; “local” does not mean an offline advisory database. You pay your own infrastructure costs when self-hosting.
