About SEON MCP Server
Connect your SEON account to any AI agent and take full control of your fraud prevention and risk management orchestration through natural conversation. SEON provides a modular and powerful platform for transaction scoring, digital footprinting, and AML compliance, and this integration allows you to retrieve risk metadata, perform real-time checks, and manage blacklists directly from your chat interface.
LangChain's ecosystem of 500+ components combines seamlessly with SEON through native MCP adapters. Connect 12 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Fraud & Risk Orchestration — Perform real-time fraud checks on transactions and registrations programmatically to protect your business revenue.
- Digital Footprint Intelligence — Retrieve social media and domain metadata for emails, phone numbers, and IP addresses directly from the AI interface.
- AML & Compliance Control — Screen users against global sanctions, PEP, and criminal watchlists to ensure regulatory compliance via natural language.
- Machine Learning & Feedback — Send feedback labels and manage custom blacklists/whitelists to train your fraud models and ensure they are always synchronized.
- Operational Monitoring — Track fraud rules, monitor account statistics, and retrieve transaction metadata using simple AI commands.
The SEON MCP Server exposes 12 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
