### Description (declared)

# cobol-parser-mcp

MCP server that parses COBOL mainframe programs and extracts structured data plus AI-powered business logic summaries — works with any LLM provider.

```bash
pip install cobol-parser-mcp            # pure parsing, no LLM needed
pip install cobol-parser-mcp[anthropic] # + Claude
pip install cobol-parser-mcp[openai]    # + GPT-4o
pip install cobol-parser-mcp[groq]      # + Groq (fast + cheap)
pip install cobol-parser-mcp[all]       # + all providers
```

Part of the mainframe modernization pipeline — takes the `manifest.json` from [`mainframe-ingest-mcp`](https://pypi.org/project/mainframe-ingest-mcp/) and produces per-program JSON files ready for code generation.

## What it extracts

For every COBOL program:

| What | Details |
|------|---------|
| **IDENTIFICATION DIVISION** | Program ID, author, date written |
| **DATA DIVISION** | All working storage variables with level numbers and PIC clauses |
| **PROCEDURE DIVISION** | Every paragraph with line ranges and PERFORM references |
| **Embedded SQL** | Every SELECT/INSERT/UPDATE/DELETE with tables and columns |
| **Embedded CICS** | Every SEND/RECEIVE MAP, LINK, XCTL, READ, WRITE |
| **AI summary** | Plain-English description of what the program does (any LLM) |

## Claude Desktop config

```json
{
  "mcpServers": {
    "cobol-parser-mcp": {
      "command": "cobol-parser-mcp",
      "env": {
        "ANTHROPIC_API_KEY": "your-key-here"
      }
    }
  }
}
```

## Usage from Python

### Parse a single file (no API key needed)

```python
from cobol_parser_mcp.tools.parser import parse_cobol_file
import json

result = parse_cobol_file("/path/to/SS6001XX.cob")
print(json.dumps(result, indent=2))
```

### Parse entire codebase with AI summaries

```python
import asyncio
from cobol_parser_mcp.tools.batch import parse_all_programs

# Using Anthropic (Claude)
result = asyncio.run(parse_all_programs(
    manifest_path="./manifest.json",  # from mainframe-ingest-mcp
    output_dir="./pars…
