What is the CrowdSec MCP Server?

Connect your CrowdSec security engine to any AI agent to take full control of your threat intelligence and network defense through natural conversation.

What you can do

  • Local Decisions — Query your Local API (LAPI) for active blocks or decisions on specific IPs, ranges, or scopes to understand current local threats.
  • Decision Streaming — Poll for real-time updates on new and deleted decisions from your local database to keep your security context synchronized.
  • Global CTI Reputation — Fetch global IP reputation data, behaviors, and classifications from the CrowdSec Community Threat Intelligence (CTI) network.
  • Security Auditing — Inspect metadata and classifications for suspicious actors directly from your command interface or code editor.

How it works

  1. Subscribe to this server
  2. Enter your CrowdSec LAPI URL, LAPI Key, and CTI Key
  3. Start managing your security posture from Claude, Cursor, or any MCP-compatible client

No more manual log diving or complex CLI commands to check if an IP is malicious. Your AI acts as a dedicated security analyst.

Who is this for?

  • Security Engineers — instantly retrieve local decision statuses and global reputation metrics without leaving the terminal
  • DevOps Teams — monitor security streams and verify IP behaviors during incident response directly from the IDE
  • System Administrators — automate the auditing of blocked ranges and suspicious network activity through natural language

Why Claude Code?

Claude Code registers CrowdSec as an MCP server in a single terminal command. Once connected, Claude Code discovers all 3 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where CrowdSec data drives decisions without human intervention.

  • Single-command setup: claude mcp add registers the server instantly. no config files to edit or applications to restart

  • Terminal-native workflow means MCP tools integrate seamlessly into shell scripts, CI/CD pipelines, and automated DevOps tasks

  • Claude Code runs headlessly, enabling unattended batch processing using CrowdSec tools in cron jobs or deployment scripts

  • Built by the same team that created the MCP protocol, ensuring first-class compatibility and the fastest adoption of new protocol features

FAQ

Frequently asked questions

01

Can I check if a specific IP address is currently blocked in my local CrowdSec instance?

Yes! Use the get_decisions tool providing the IP address. Your agent will query your Local API and return any active decisions, including the reason and duration of the block.

02

How do I see the latest security threats detected by my server in real-time?

You can use the get_decisions_stream tool. This allows your agent to poll for new and deleted decisions, giving you a clear view of recent security activity on your infrastructure.

03

Can I verify an IP's global reputation even if it hasn't attacked my server yet?

Absolutely. The get_cti_smoke tool queries the global CrowdSec CTI network. It provides background information, attack behaviors, and risk scores for any IP based on community data.

04

How do I add an MCP server to Claude Code?

Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.

05

Can Claude Code run MCP tools in headless mode?

Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.

06

How do I list all connected MCP servers?

Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
