The Problem

IBM i data is locked away.

Querying an IBM i database requires specialized knowledge, specific tooling, and usually a database administrator. For most developers, production data is effectively inaccessible without going through a ticket queue.

  • Requires DB admin or green-screen knowledge
  • Every developer needs drivers and credentials configured
  • Schema discovery is slow and manual
  • Writing SQL against unfamiliar tables takes hours
The Solution

Just ask Claude.

Install db2-bridge once on a Windows machine with ODBC access to your IBM i. Your whole team connects through it. Claude handles the queries — you just ask questions.

  • One install, accessible to the whole team
  • No per-developer drivers or credentials
  • Claude explores schemas and writes SQL for you
  • Fine-grained access control keeps sensitive data safe
Features

Everything you need. Nothing you don't.

Schema Exploration

Claude can list libraries, describe tables, and understand column types — without you writing a single query.

Access Control

Whitelist or blacklist libraries and tables. Read-only by default. Write access is opt-in and separately controlled.

Network Deployable

Run on one machine with ODBC access. Developers on other machines just point their Claude config to the HTTP endpoint.

Windows Service

Install as a Windows service with one command. Auto-starts on boot, auto-restarts on crash. No terminal window required.

Connection Pooling

Configurable ODBC connection pool handles multiple concurrent users without opening a new connection per request.

Single Executable

Distributed as a .zip containing a standalone .exe. No Node.js installation required on the host machine.

Setup

Up and running in minutes.

01

Download

Download and extract db2-bridge.zip, then edit config.yaml with your IBM i hostname and credentials.

02

Purchase

Choose a license tier and complete checkout. You'll be redirected back to enter your machine ID and generate your license.

03

Activate

Run db2-bridge.exe --machine-id and paste the output. Your signed license.dat is emailed to you instantly.

04

Point Claude at It

Add one entry to your .mcp.json. Claude automatically discovers all five tools.

In Practice

Natural language → DB2 queries.

Once connected, Claude reads your IBM i like a seasoned DBA. Ask questions in plain English — Claude handles the SQL.

 5 orders since January?"
Security

You control what Claude can see.

db2-bridge is read-only by default. Write access is explicitly opt-in. Access rules apply at both the library and table level.

ToolDefaultConfigurable

list_tablesopenwhitelist / blacklist

execute_queryread onlywhitelist / blacklist
execute_writedisabledopt-in, whitelist / blacklist

How access rules work

On first startup, db2-bridge generates an access config file you can edit. Whitelist mode allows only the libraries you specify. Blacklist mode blocks sensitive libraries while leaving everything else open.

DDL statements (DROP, CREATE, ALTER, TRUNCATE) are always blocked regardless of write access settings. Claude is explicitly warned before using write tools.

A single service account handles all connections — your developers never need personal IBM i credentials.
