## What it does

Senzing gives an AI assistant tools for entity resolution. It can compare records from separate sources, merge matching entries, and screen them against watchlists. Ask about a match to see the evidence behind joining two records or keeping them separate.

The server also searches Senzing documentation and indexed code, and can help with SDKs for Python, Java, and C#. Its remote endpoint uses Streamable HTTP and requires no authentication: `https://mcp.senzing.com/mcp`. Hosted access is free; Senzing software is licensed separately.

Working with your own data and running Senzing require an assistant that can execute code. If your network restricts outbound access, allow `mcp.senzing.com` through the relevant controls.
