IBM i MCP Server

The Model Context Protocol (MCP) server for IBM i systems.

Quick Start

# Install dependencies
npm install

# Build
npm run build

# Run server (HTTP mode)
npm run start:http

# Run server (stdio mode)
npm run start:stdio

# Run tests
npm test

Configuration

Create a .env file in the root of the monorepo (parent directory):

cp ../.env.example ../.env

The server will automatically detect configuration in:

1. Current working directory (for production deployments)
2. Parent directory (for monorepo development)
3. Server directory (for local overrides)

Tool Configuration

By default, the server loads SQL tools from ../tools/. Override with:

TOOLS_YAML_PATH=../tools npm run start:http

Or set in your .env file:

TOOLS_YAML_PATH=tools

Documentation

See the root README for complete documentation and deployment guides.
