UOFastCoder + UOFastMCP · open source

Write U2 code with AI


that reads your U2 Unidata/Universe DICTionaries & UniBasic code.

Connect VS Code, Cursor, or Claude Desktop to your live UniData or UniVerse database. Generate BASIC, APIs, Python, React UIs, and reports — grounded in real data, not hallucinations.

What you can build

Six things AI can generate
against your live U2 data

U2 BASIC Programs

Read/write subroutines, UPDATE programs, COMMON blocks, and multi-value loops — field names and types pulled from live DICTs.

SUBROUTINES MV-AWARE COMMON

REST APIs

FastAPI or Express stubs from any U2 file + DICT. Full CRUD, correct field names, MV handling, and typed schemas.

FASTAPI EXPRESS OPENAPI

Python Scripts

UOPY wrappers, ETL routines, and data migration scripts with full field awareness — no boilerplate, no guessed field names.

UOPY ETL MIGRATION

React UI Components

SB+ screen extraction → React stubs with field positions, labels, validation rules, and process chain hooks. MV fields as dynamic rows.

SB+ EXTRACT REACT VALIDATION

Reports & Queries

Natural language → U2 ReportWriter specs, LIST/SORT commands, and formatted output templates. Describe it, get runnable U2 syntax.

REPORTWRITER LIST/SORT

Update Existing Logic

Point the agent at existing BP programs. It reads the source, understands it, then refactors, extends, or documents it — fully contextualized.

REFACTOR DOCUMENT EXTEND
Quickstart

Up and running
in four steps

01

Install UOFastMCP

The MCP server wraps your UniData or UniVerse account and exposes 23 typed tools to any AI client.

pip install uofast-mcp
uofast-mcp start --account /u2/PRODVOL
02

Connect VS Code

Add UOFastMCP to .vscode/mcp.json — same config works for Cursor and Claude Desktop.

// .vscode/mcp.json
{ "mcpServers": {
  "uofastmcp": {
    "command": "python",
    "args": ["-m", "uofastmcp"]
  }
}}
03

Install UOFastCoder

Pre-built agent workflows that connect to UOFastMCP and generate production-ready code.

pip install uofastcoder
04

Run an agent

Pick a workflow. The agent reads your live DICTs and writes output directly to your project.

# BASIC subroutine from live DICT
uofastcoder run basic-generator --file CUST.MASTER

# Full modernization audit
uofastcoder run modernization-auditor

Two packages.
Everything you need.

OPEN SOURCE

UOFastCoder

Agents and skills that orchestrate AI-driven code generation against your live U2 database. Composable, readable, and extendable.

  • Pre-built agents: BASIC, API, React, audit, schema
  • Skills call UOFastMCP tools — no direct U2 deps
  • Works in VS Code, Cursor, Claude Desktop, any MCP client
  • Structured JSON output for downstream pipelines
  • Extend with custom agents using the SDK
GitHub → UOFastCoder ↗
MCP SERVER

UOFastMCP

The MCP layer connecting AI clients directly to UniData or UniVerse. Wraps Rocket's UOPY library — 23 typed, AI-callable tools, no middleware.

  • 23 tools: read/write records, query files, DICT ops
  • Read and compile BASIC programs from BP files
  • list_files, get_dict_items, execute_command, and more
  • Supports UniData (ud) and UniVerse (uv)
  • Connection pooling and error recovery built in

Modernization

Your U2 logic,
in modern systems.

Decades of business logic live in your U2 environment. RokiPark doesn't replace it — it reads it, understands it, and generates the modern layer around it. BASIC becomes Python. SB+ screens become React. Reports become REST endpoints.
