crowdsec-service-api

crowdsec-service-api is a skill for Claude Code, Codex from crowdsecurity/crowdsec-skill. It costs 135 tokens per session (2,012 once invoked), scanned C, original, MIT.

A skill for using CrowdSec’s cloud Service API, a web service for managing security lists and integrations. It works with cloud blocklists, allowlists, decisions, and firewall connections rather than the local CrowdSec engine.

In plain words
What is it for?
Use it to add or remove IP addresses from cloud blocklists, manage allowlists and decisions, subscribe engines or organizations to lists, and connect firewalls such as Palo Alto or Fortinet.
Why use it?
Managing security data across several systems manually is slow and error-prone. This helps automate changes made in the CrowdSec cloud console and distribute them to connected systems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

crowdsec-service-api scanned grade C with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

| Add IPs to a blocklist *(mutating — confirm)* | `curl -s -H "x-api-key: $KEY" -H 'Content-Type: application/json' -X POST "$B/blocklists/$ID/ips" -d '{"ips":["1.2.3.4"]}'` |

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

[ -n "$KEY" ] || echo "No key: export CROWDSEC_SAPI_KEY or store it in ~/.config/crowdsec/sapi_key (chmod 0600)"

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CrowdSec Service API (SAPI) — cloud blocklist / allowlist / integration automation

SAPI is the premium REST API behind the CrowdSec Console. It manages cloud-side objects (private blocklists, allowlists, decisions, firewall integrations) that then push down to enrolled engines and bouncers. It is not the local engine API — there is no cscli here, only HTTPS.

Boundary — this skill vs the crowdsec skill

You want to… Use
Create/manage a private blocklist in the cloud, push IPs to it via API this skill
Wire a firewall/appliance (Palo Alto, Fortinet…) to a cloud integration this skill
Manage cloud allowlists, subscribe engines/tags/orgs to lists this skill
Create/manage org-level decisions (targeted or ad-hoc bans, non-IP scopes, per tag/entity) this skill
Pull remediation ROI metrics this skill
Install / run / debug the local engine, cscli, bouncers, WAF the crowdsec skill
Enroll an engine into the Console (cscli console enroll) the crowdsec skill → references/install/console.md
Configure a local allowlist/whitelist on one engine the crowdsec skill → references/configure/allowlists.md

Cloud allowlists/blocklists here only take effect on an engine once that engine is enrolled and subscribed to the list. The enrollment half lives in the crowdsec skill.

Operating contract

Every call here hits production and can change what subscribed engines enforce.

1 — Resolve the key. Never echo it, never write it anywhere but the file below:

KEY="${CROWDSEC_SAPI_KEY:-$(cat ~/.config/crowdsec/sapi_key 2>/dev/null)}"
[ -n "$KEY" ] || echo "No key: export CROWDSEC_SAPI_KEY or store it in ~/.config/crowdsec/sapi_key (chmod 0600)"

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

crowdsec-service-api is a skill published in the GitHub repository crowdsecurity/crowdsec-skill (23 stars, last pushed 2d ago), licensed MIT. It adds 135 tokens to every session and 2,012 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it C with 3 findings (sends data to an external url, asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
