GitHub - core-ncsrd/5g-ddos-mcp: Agentic 5G attack MCP server

Model Context Protocol server for real-time 5G DDoS detection and response
Powered by the NCSRD-DS-5GDDoS dataset — a physical 3GPP-compliant 5G testbed from the EU Horizon PRIVATEER project

What It Does

Gives any LLM agent the ability to detect, explain, and respond to 5G DDoS attacks:

Tool	What it does
`detect_anomaly`	Classify live 5G telemetry as benign/attack — returns type, confidence, severity
`explain_attack`	Generate a natural-language incident report via the configured LLM
`recommend_response`	Slice-aware mitigation plan with generic REST API call examples
`query_history`	Search past incidents + dataset reference patterns for few-shot LLM reasoning

Supports SYN, UDP, ICMP, DNS, and GTP-U flooding (the last being 5G-specific, critical severity).

Quick Start

Pick your LLM backend and follow the matching path. The server runs in demo mode (rule-based heuristics) without a trained model, so you can try all tools immediately.

Option A — Claude (Anthropic API)

Best output quality for incident reports and recommendations.

# 1. Clone and install
git clone https://github.com/ncsrd/5g-ddos-mcp
cd 5g-ddos-mcp
pip install -r requirements.txt

# 2. Configure
cp .env.example .env
#    Set: LLM_BACKEND=claude
#    Set: ANTHROPIC_API_KEY=sk-ant-...

# 3. Run
python -m src.server

Connect in claude_desktop_config.json:

{
  "mcpServers": {
    "5g-ddos": {
      "command": "python",
      "args": ["-m", "src.server"],
      "cwd": "/path/to/5g-ddos-mcp",
      "env": {
        "LLM_BACKEND": "claude",
        "ANTHROPIC_API_KEY": "sk-ant-..."
      }
    }
  }
}

Option B — Ollama (local open-source LLMs, fully offline)

Best for air-gapped or privacy-sensitive deployments. No data leaves your machine.

Step 1 — Install Ollama

# macOS / Linux
curl -fsSL https://ollama.com/install.sh | sh

# Windows: download from https://ollama.com/download

Step 2 — Pull a model

ollama pull llama3.2       # 3B (fast) or 8B (balanced) — recommended default
ollama pull mistral        # 7B — strong reasoning
ollama pull phi4           # 14B — best structured output
ollama pull gemma3         # Google Gemma 3, 4B–27B
ollama pull deepseek-r1    # 8B chain-of-thought distill
ollama pull qwen2.5        # 7B / 14B / 72B

Step 3 — Run the MCP server

cp .env.example .env
#    Set: LLM_BACKEND=ollama
#    Set: OLLAMA_MODEL=llama3.2   (or whichever you pulled)
#    OLLAMA_BASE_URL defaults to http://localhost:11434

python -m src.server

Connect in claude_desktop_config.json:

{
  "mcpServers": {
    "5g-ddos": {
      "command": "python",
      "args": ["-m", "src.server"],
      "cwd": "/path/to/5g-ddos-mcp",
      "env": {
        "LLM_BACKEND": "ollama",
        "OLLAMA_MODEL": "llama3.2"
      }
    }
  }
}

Option C — OpenAI-compatible endpoint

Works with vLLM, LM Studio, Groq, Together.ai, Mistral API, Perplexity, and any other OpenAI-compatible provider.

cp .env.example .env
#    Set: LLM_BACKEND=openai_compatible
#    Set: OPENAI_BASE_URL=<your endpoint>
#    Set: OPENAI_MODEL=<model name>
#    Set: OPENAI_API_KEY=<your key>

python -m src.server

Provider examples:

Provider	`OPENAI_BASE_URL`	`OPENAI_MODEL`
vLLM (self-hosted)	`http://localhost:8080/v1`	your deployed model
LM Studio (local)	`http://localhost:1234/v1`	model loaded in LM Studio
Groq	`https://api.groq.com/openai/v1`	`llama-3.3-70b-versatile`
Together.ai	`https://api.together.xyz/v1`	`meta-llama/Llama-3-70b-chat-hf`
Mistral API	`https://api.mistral.ai/v1`	`mistral-large-latest`
Perplexity	`https://api.perplexity.ai`	`llama-3.1-sonar-large-128k-online`
OpenAI	`https://api.openai.com/v1`	`gpt-4o`

Option D — Docker (any backend)

# Build
docker build -t 5g-ddos-mcp .

# Run with Claude
docker run --env-file .env -p 8000:8000 \
  -v $(pwd)/models:/app/models:ro \
  -v $(pwd)/data:/app/data:ro \
  5g-ddos-mcp

# Run with Ollama (Ollama running on host)
docker run -p 8000:8000 \
  -e LLM_BACKEND=ollama \
  -e OLLAMA_BASE_URL=http://host.docker.internal:11434 \
  -e OLLAMA_MODEL=llama3.2 \
  5g-ddos-mcp

# Full stack: MCP server + Ollama side-by-side
docker compose --profile with-ollama up
# Then pull a model inside the Ollama container:
docker exec -it ollama ollama pull llama3.2

# Full stack with InfluxDB + Grafana (mirrors the NCSRD testbed pipeline)
docker compose --profile full up

Option E — Kubernetes

# 1. Apply namespace, storage, and config
kubectl apply -f k8s/namespace.yaml
kubectl apply -f k8s/pvc.yaml
kubectl apply -f k8s/configmap.yaml

# 2. Create secrets (replace with real values)
kubectl create secret generic 5g-ddos-mcp-secrets \
  --from-literal=ANTHROPIC_API_KEY=sk-ant-... \
  -n 5g-ddos-mcp

# 3. Deploy (set LLM_BACKEND in k8s/deployment.yaml before applying)
kubectl apply -f k8s/deployment.yaml
kubectl apply -f k8s/service.yaml

# 4. Train the model inside the cluster (after populating the data PVC)
kubectl apply -f k8s/train-job.yaml
kubectl logs -f job/train-classifier -n 5g-ddos-mcp

# 5. Check status
kubectl get pods -n 5g-ddos-mcp

To deploy Ollama as a sidecar for a fully self-contained cluster:

# Ollama deployment + service are already included in k8s/deployment.yaml
# Set LLM_BACKEND=ollama and OLLAMA_BASE_URL=http://ollama-service:11434 in configmap.yaml
kubectl apply -f k8s/deployment.yaml   # deploys both mcp-server and ollama
kubectl apply -f k8s/service.yaml
# Then exec into the Ollama pod to pull a model:
kubectl exec -it deploy/ollama -n 5g-ddos-mcp -- ollama pull llama3.2

Dataset Setup

The ML model requires the NCSRD-DS-5GDDoS v3.0 dataset (~620 MB), which must be downloaded separately. The server runs in heuristic demo mode without it.

# Automatic download from Zenodo (DOI: 10.5281/zenodo.13900057)
chmod +x scripts/download_dataset.sh
./scripts/download_dataset.sh

# Then train the classifier (~5–15 min depending on hardware)
python scripts/train_model.py

# Quick smoke-test with 100k rows
python scripts/train_model.py --nrows 100000

See data/DATASET_INSTRUCTIONS.md for full details on files and manual download.

Target metrics (from published results on this dataset):

Metric	Target	Published
Binary F1	> 0.95	0.98
AUC-ROC	> 0.99	0.999
Multi-class Weighted F1	> 0.95	0.98

CLI

The 5g-ddos command lets you run detections, query history, get recommendations, and manage the dataset directly from your terminal — no MCP client required.

pip install -e ".[all]"   # installs the 5g-ddos entry point
5g-ddos --help

`server` — Start the MCP server

5g-ddos server                          # uses LLM_BACKEND from .env

5g-ddos server --backend claude

`detect` — Classify 5G telemetry

# Inline single-sample detection
5g-ddos detect --ul-bitrate 9500000 --dl-bitrate 1200000 \
               --ul-retx 0.42 --pdu-session-setup-request 95 \
               --ue-id UE-007

# Batch detection from a CSV file (matches NCSRD dataset schema)
5g-ddos detect --input telemetry.csv --format table
5g-ddos detect --input telemetry.csv --format csv --output results.csv

# Output formats: table (default) | json | csv

Tier 1 — Perception: XGBoost classifier (trained on NCSRD-DS-5GDDoS) detects attacks from real-time telemetry.

Tier 2 — Reasoning: LLM produces contextual incident reports and mitigation recommendations.

Tier 3 — Action: Generic REST API integration for automated response (blacklist UE, isolate slice, rate-limit). Compatible with Open5GS, free5GC, OAI, or any custom NMS — set RESPONSE_API_URL to enable.
