baucli 1.0.38

Extracts verified business-logic and schema context from Oracle, PostgreSQL, MySQL and SQL Server

BAUCLI

Business-logic context for your databases — kept true to production.

BAUCLI runs on the developer's machine. It connects to Oracle, PostgreSQL, MySQL and SQL Server, extracts the real structure and PL/SQL logic, and turns it into documentation that is reviewed by people and consumed by AI — then writes it back where it belongs: COMMENT ON in the database and context files in your repository.

Because the context is extracted from the live database on every sync, it does not drift away from what is actually deployed. That is the difference between documentation you trust and documentation you stopped reading.

It is the local component of the BAU platform (BEG Application Utilities), which stores the catalog, runs the AI drafting and holds the approval workflow.

# Add PostgreSQL staging
baucli connect --name staging_pg --engine postgresql --host pg-staging --port 5432 --database erp --user app_user

# Add SQL Server production
baucli connect --name prod_mssql --engine mssql --host sql-prod --port 1433 --database erp --user bau_reader

# Sync specific database
baucli sync --db staging_pg

# Sync all
baucli sync --all

# Set default
baucli db default dev_oracle

Configuration

Config file: ~/.baucli/config.json

{
  "license_key": "BAU-XXXX-XXXX-XXXX-XXXX",
  "api_url": "https://begbrokerdev.begcloud.com/ords/bauctx/api/v1",
  "api_key": "bau_cli_xxxx",
  "tenant_code": "ACME_CORP",
  "default_db": "dev_oracle",
  "databases": {
    "dev_oracle": {
      "engine": "oracle",
      "host": "localhost",
      "port": 1521,
      "service": "XEPDB1",
      "user": "DEMO_HR",
      "schemas": ["DEMO_HR"]
    },
    "staging_pg": {
      "engine": "postgresql",

    }
  },

  "context_output": "CLAUDE.md"
}

Passwords are stored separately in ~/.baucli/.credentials (restricted permissions).

Override config dir with BAUCLI_HOME=~/.baucli-tenant2 to keep multiple isolated profiles on the same machine.

Security

• Database credentials never leave the developer's machine
• Only extracted metadata and source code are sent to BAU Server via HTTPS
• API key uses SHA256 hash — plain token shown once at baucli init
• Passwords stored in ~/.baucli/.credentials with mode 600 (or OS keychain when available)
• BAU Server never executes DDL on your database

Requirements

• Python 3.9+
• Network access to BAU Server (HTTPS)
• Database access (read-only on DBA_SOURCE, DBA_TABLES, etc.)
