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
- Subscribe to this server
- Enter your CrowdSec LAPI URL, LAPI Key, and CTI Key
- 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

Observability integrations show exactly what CrowdSec tools were called, what data was returned, and how it influenced the final answer
CrowdSec in LlamaIndex
CrowdSec and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect CrowdSec to LlamaIndex through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

Why teams choose Vinkius for CrowdSec in LlamaIndex
The CrowdSec MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 3 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in LlamaIndex only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.
* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
CrowdSec for LlamaIndex
Every tool call from LlamaIndex to the CrowdSec MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
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.
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.
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.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query CrowdSec tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
