Reltio MCP Server

A Python-based Model Context Protocol (MCP) server that connects AI assistants to Reltio data through a set of structured, reusable tools.

The server exposes Reltio entity search, entity details, record counts, and relationship retrieval as MCP tools, allowing an MCP-compatible AI client to interact with Reltio data through natural-language requests.


🚀 Overview

This project demonstrates how to build an MCP server that acts as a bridge between an AI assistant and a Reltio data environment.

Instead of requiring the AI assistant to directly understand and manage Reltio API requests, the MCP server exposes high-level tools such as:

  • Search contacts

  • Search organizations

  • Search locations

  • Search stations

  • Search voyagers

  • Search any supported entity type

  • Retrieve complete entity details

  • Count records by entity type

  • Retrieve entity relationships

The server communicates with Reltio using its REST APIs and exposes the functionality through the Model Context Protocol (MCP).
