# crowdsec The official CrowdSec plugin for AI coding agents. It walks your agent through deploying the engine, wiring bouncers, turning on the WAF and debugging why nothing gets blocked. - plugin · `type=plugin` · Claude Code · ★ 26 - Author: CrowdSec - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/crowdsecurity/crowdsec-skill - Updated: 2026-09-25 - HTML: https://affpapa.org/en/nevibecode/plugins/crowdsec ## What it does Two skills ship inside. The first, `crowdsec`, is the hands-on operator: it stands up the engine, drives `cscli`, pulls collections and parsers from the hub, hooks a bouncer into nginx, traefik, caddy, apache or a firewall, deploys the WAF/AppSec component, and digs into logs when alerts stay silent. The second, `crowdsec-service-api`, talks to the cloud Console Service API with your key — building blocklists and allowlists, adding addresses with expiry, wiring firewall and appliance integrations, and pulling remediation metrics. Every state change through that skill waits for an explicit confirmation. Behind both sit 37 reference documents. They cover bare-metal and systemd, Docker, Kubernetes/Helm, pfSense/OPNsense, acquisition and profile setup, ban durations, notifications, health checks, upgrades and rollback, multi-server layouts with a remote LAPI and mTLS, plus triage for common errors. One document handles a fail2ban migration. This is an operational tool. It deploys, configures and debugs CrowdSec — it does not author detection content, so parsers, scenarios and WAF/AppSec rules are yours to write. The Service API skill needs a premium Console API key; without one, the cloud operations have nothing to authenticate with. ## Install ### Claude Code (native platform) **Plugin marketplace** In the agent chat (not a shell): ```text /plugin install crowdsec@claude-plugins-official ``` In the agent chat (not a shell): ```text /plugin marketplace add anthropics/claude-plugins-official ``` ## When to use it - install CrowdSec on a systemd host and wire the nginx bouncer - deploy the engine into a Kubernetes cluster and enroll it in the Console - turn on WAF/AppSec and set up bot detection - find out why an nginx server reports no attacks - move fail2ban jails over to CrowdSec ## Example prompts - Install CrowdSec on this server and set up the nginx bouncer - Deploy CrowdSec in my Kubernetes cluster and enroll it in the Console - There's a decision for this IP but it isn't being blocked — figure out why ## Source text · SKILL.md · MIT Below is the content of a third-party file.

CrowdSec # CrowdSec Skill for Claude Code & Codex **The official CrowdSec plugin for AI coding agents.** It bundles two [Agent Skills](https://docs.claude.com/en/docs/claude-code/skills) that let Claude Code, Codex, and Claude.ai install, configure, operate, and debug [CrowdSec](https://docs.crowdsec.net) — the engine, `cscli`, bouncers, and the WAF/AppSec component — across bare-metal/systemd, Docker, pfSense/OPNsense, and Kubernetes/Helm.

--- This plugin bundles **two [Agent Skills](https://docs.claude.com/en/docs/claude-code/skills)**: - **`crowdsec`** — a hands-on CrowdSec operator. Stand up an engine, wire a bouncer, enable the WAF, or figure out why nothing's getting blocked. It knows the `cscli` commands, the config layout, the failure modes, and the safe way through each across **bare-metal/systemd, Docker, pfSense/OPNsense and Kubernetes/Helm**. - **`crowdsec-service-api`** — drives the premium **Console Service API** (cloud) on your behalf with your API key: create and populate blocklists/allowlists, wire firewall/appliance integrations, pull remediation ROI metrics, and manage org-level decisions — every state change gated behind an explicit confirmation. ## What it covers **`crowdsec` (operational):** | Area | Covered | |---|---| | **Install** | bare-metal/systemd · Docker · Kubernetes/Helm · pfSense/OPNsense · Console enrollment | | **Bouncers** | firewall (iptables/nftables/ipset) · nginx · traefik · caddy · apache · and more | | **WAF / AppSec** | deploy · configure · troubleshoot the AppSec component · bot detection | | **Hub** | install collections/parsers/scenarios · update · debug | | **Configure** | acquisition · profiles & ban durations · notifications · allowlists | | **Operate** | health checks & smoke tests · upgrades & rollback · multi-server / remote LAPI / mTLS | | **Debug** | logs not parsing · no alerts firing · bouncer not blocking · specific errors | **`crowdsec-service-api` (premium cloud API):** | Area | Covered | |---|---| | **Blocklists** | create · add/remove/bulk IPs (with expiry) · download · share across orgs · subscribe engines/bouncers | | **Allowlists** | create · items with expiry · subscribe by engine/tag/org | | **Integrations** | firewall/appliance feeds (Palo Alto, Fortinet, Cisco, F5, Sophos, pfSense/OPNsense…) · paginated Basic-auth content pull | | **Metrics** | remediation ROI (traffic dropped, bytes/egress saved, attacks prevented) | | **Decisions** | org-level decisions + aggregated (read/manage) | ## Install The skill loads automatically once installed. Just talk to your agent about CrowdSec. > **Naming:** the marketplace is `crowdsecurity`, the plugin inside it is `crowdsec`, > and the plugin ships two skills — `crowdsec` and `crowdsec-service-api`. **On Claude Code** ```text /plugin marketplace add crowdsecurity/crowdsec-skill /plugin install crowdsec@crowdsecurity ``` Update later with: ```text /plugin marketplace update crowdsecurity ``` **On Codex:** install the skill with: ```text skill-installer crowdsecurity/crowdsec-skill ``` **On Claude.ai (web)** Download `crowdsec-skill-vX.Y.Z.zip` from the [latest release](https://github.com/crowdsecurity/crowdsec-skill/releases/latest) and upload it in the web skill uploader. **Or directly with skills.sh** ```bash ```` END THIRD-PARTY FILE d7b83a412236b4c4 The third-party file has ended.
