IBM i MCP Server

MCP Server

An open-source, IBM-published server implementing the Model Context Protocol (MCP), letting AI agents and LLMs query Db2 for i data and take defined actions on IBM i using natural language. In beta since October 2025.

The Model Context Protocol (MCP) is an open standard for connecting AI agents and LLM-powered tools to external data sources and actions. The IBM i MCP Server is IBM's open-source implementation of MCP for IBM i, published on GitHub and opened in beta on October 27, 2025. It uses Mapepire as its underlying Db2 for i connectivity layer and exposes YAML-defined SQL tools, shared with a companion ibmi CLI, so that MCP-compatible AI clients such as Claude, GPT-4-based tools, and local LLMs can query Db2 for i data, inspect system objects, and take defined actions on IBM i through natural language. It is a connectivity and agent-tooling layer, not a machine learning or predictive-modeling feature.
