### Description (declared)

# mainframe-ingest-mcp

An MCP server that ingests COBOL mainframe codebases from ZIP files and produces a structured JSON manifest — ready for downstream modernization tools.

```bash
pip install mainframe-ingest-mcp
```

---

## What is this?

Mainframe modernization projects always start with the same problem: **nobody knows what's in the codebase.** Thousands of COBOL files, copybooks, BMS screens, JCL jobs, and CSD exports — all sitting in a ZIP someone exported from the mainframe.

`mainframe-ingest-mcp` solves the discovery step. Point it at any mainframe ZIP and it will:

- Classify every file by type (COBOL, copybook, BMS screen, JCL, DB2 DDL, CSD export)
- Detect and convert EBCDIC encoding to UTF-8
- Scan every COPY, EXEC SQL INCLUDE, EXEC CICS, and CALL statement
- Build a full dependency graph (which programs use which copybooks)
- Parse CICS transaction definitions and suggest FastAPI REST routes
- Map every BMS screen to an Angular component name
- Produce a single `manifest.json` — the handoff document for the rest of the pipeline

It has been tested against a real 294-file, 118,000-line government CICS application and resolves 99%+ of dependencies with zero configuration.

## Installation

```bash
pip install mainframe-ingest-mcp
```

Requires Python 3.10+.

## Connecting to Claude Desktop

This is an MCP server — it runs locally and exposes tools to Claude Desktop.

**Step 1:** Find your Claude Desktop config file:

| OS      | Location |
|---------|----------|
| macOS   | `~/Library/Application Support/Claude/claude_desktop_config.json` |
| Windows | `%APPDATA%\Claude\claude_desktop_config.json` |
| Linux   | `~/.config/Claude/claude_desktop_config.json` |

**Step 2:** Add this to the config:

```json
{
  "mcpServers": {
    "mainframe-ingest-mcp": {
      "command": "mainframe-ingest-mcp"
    }
  }
}
```

**Step 3:** Restart Claude Desktop.

That's it. The tools will appear automatically. You can now say to Claude:
