How to Set Up and Use GeneXus 18
GeneXus MCP is a Model Context Protocol server that bridges AI coding assistants to GeneXus 18 Knowledge Bases, exposing 30+ tool families for reading, editing, analyzing, and building KB objects including transactions, web panels, procedures, SDTs, and WorkWithPlus patterns. It auto-detects and registers itself with Claude Desktop, Claude Code, Cursor, and other compatible AI tools. GeneXus developers use it to perform impact analysis, refactor objects, generate documentation, and apply code edits across their KB without leaving their AI assistant.
Prerequisites
- GeneXus 18 installed on Windows (the server needs the GeneXus installation path)
- Node.js and npx available on your PATH
- An existing GeneXus Knowledge Base (KB) to connect to
- An MCP client such as Claude Desktop, Claude Code, or Cursor
Run the initialization wizard
Use npx to run the GeneXus MCP initializer, pointing it to your KB directory and GeneXus installation. The interactive flag prompts you for all settings.
npx genexus-mcp@latest init --interactiveOr initialize with explicit paths
Alternatively, provide the KB and GeneXus paths directly on the command line for non-interactive setup.
npx genexus-mcp@latest init --kb "C:\KBs\YourKB" --gx "C:\Program Files (x86)\GeneXus\GeneXus18"Verify server health
Run the doctor command to confirm the server is correctly configured and can communicate with GeneXus.
npx genexus-mcp@latest doctor --mcp-smokeCheck registered clients
