How do I use crowdsec-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@crowdsec-mcp show recent decisions from CrowdSec" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

crowdsec-mcp

A read-only MCP server for CrowdSec, exposing decisions and alerts.

Tools

name	endpoint	required secret
`list_decisions`	`GET /v1/decisions`	bouncer key
`decisions_stream`	`GET /v1/decisions/stream`	bouncer key
`list_alerts`	`GET /v1/alerts`	machine login
`get_alert`	`GET /v1/alerts/{id}`	machine login

Related MCP server: enoch-mcp

Credentials

We need two credential types:

Decisions need only a bouncer API key (cscli bouncers add <name>), which is inherently read-only. This alone is enough for list_decisions / decisions_stream.
Alerts are only reachable with machine credentials (cscli machines add), exchanged for a short-lived JWT. That credential is technically read-write on LAPI, so this server only ever issues GET requests (plus the login POST). The alert tools stay disabled unless machine credentials are configured.

Configuration (environment variables)

name	default	use
`CROWDSEC_LAPI_URL`	`http://localhost:8080`	LAPI base URL
`CROWDSEC_BOUNCER_KEY`	—	bouncer API key (enables decision tools)
`CROWDSEC_MACHINE_ID`	—	machine id (enables alert tools)
`CROWDSEC_MACHINE_PASSWORD`	—	machine password
`CROWDSEC_VERIFY_TLS`	`true`	set `false` to skip TLS verification
