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 Windsurf?

Windsurf's Cascade agent chains multiple CrowdSec tool calls autonomously. query data, analyze results, and generate code in a single agentic session. Paste Vinkius Edge URL, reload, and all 3 tools are immediately available. Real-time tool feedback appears inline, so you see API responses directly in your editor.

  • Windsurf's Cascade agent autonomously chains multiple tool calls in sequence, solving complex multi-step tasks without manual intervention

  • Purpose-built for agentic workflows. Cascade understands context across your entire codebase and integrates MCP tools natively

  • JSON-based configuration means zero code changes: paste a URL, reload, and all 3 tools are immediately available

  • Real-time tool feedback is displayed inline, so you see API responses directly in your editor without switching contexts

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 does Windsurf discover MCP tools?

Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.

05

Can Cascade chain multiple MCP tool calls?

Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.

06

Does Windsurf support multiple MCP servers?

Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.
