Nothing serious here today

Today is the operative word: we check IBM DB2 for i every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

claude mcp add mcp-server-db2i -- npx -y mcp-server-db2i

This one needs environment variables set before it will start: DB2I_HOSTNAME (IBM i hostname or IPv4 address), DB2I_USERNAME (IBM i user profile), DB2I_PASSWORD (IBM i password), DB2I_PORT (DRDA port), DB2I_DATABASE (Database name), DB2I_SCHEMA (Default schema (library)), QUERY_ALLOWED_SCHEMAS (Comma-separated schemas the server may read. Empty disables the check.). The author declared them in the registry entry; get the values from the project itself.

IBM DB2 for i — questions

Answers built from our own checks of this server.

Why is there no uptime for IBM DB2 for i?

IBM DB2 for i runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package mcp-server-db2i.

How do I connect IBM DB2 for i?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls mcp-server-db2i straight from npm; nothing to host, nothing to sign up for.

Is IBM DB2 for i open source?

Yes — it is published under the MIT licence, written in TypeScript, 20 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
