# INI Parser Engine MCP

> INI Parser Engine converts configuration files between INI format and JSON format while preserving structure and comments. It handles complex inputs like `php.ini`, MySQL's `my.cnf`, Git configs, and `.editorconfig` files. The tool ensures bidirectional conversion with absolute precision for sections, nested keys, and multiline values.

## Description

When your agent encounters legacy system configurations—think `php.ini` or a database’s `my.cnf`—it needs to read the raw INI syntax accurately. This MCP solves that problem. It parses configuration files in both directions: converting messy INI text into clean JSON, and doing the reverse. The parser handles sections (like `[database]`), key-value pairs, and even inline comments without losing data context. You can connect this MCP through Vinkius to any compatible client and route structured config data between formats using simple conversation prompts. This eliminates manual parsing steps and lets your agent treat configuration files like native data structures.

## Tools

### parse_ini
Converts INI configuration files (like `my.cnf`, `php.ini`, `.editorconfig`) to JSON and vice versa, correctly preserving sections and comments.

## Prompt Examples

**Prompt:** 
```
Convert this php.ini to JSON so I can inspect the memory_limit setting.
```

**Response:** 
```
INI Conversion: JSON output generated with all sections preserved.
```

**Prompt:** 
```
Generate a valid .editorconfig from this JSON configuration.
```

**Response:** 
```
INI Conversion: Valid .editorconfig generated with proper sections.
```

**Prompt:** 
```
Parse the MySQL my.cnf and extract the [mysqld] section as JSON.
```

**Response:** 
```
INI Conversion: [mysqld] section extracted with max_connections, innodb_buffer_pool_size.
```

## Capabilities

### Convert INI to JSON
Pass raw INI content (from a file or clipboard) and receive structured, key-value JSON output.

### Convert JSON to INI
Provide structured data in JSON format and get a valid, formatted INI configuration block back.

### Handle Specific Config Types
Parses syntax specific to common files like `my.cnf`, `.editorconfig`, or Git configurations.

### Preserve Structural Elements
Keeps sections, nested keys (e.g., `key.subkey`), and inline comments during conversion.

## Use Cases

### Migrating an old web application
A developer needs to port a PHP app that uses `php.ini` settings. They use your agent with this MCP to convert the entire `php.ini` file into structured JSON, allowing the modern deployment tool to ingest every setting accurately.

### Debugging database connection issues
An SRE gets a raw dump of a MySQL server's `my.cnf`. They pass this to your agent and use the MCP to extract only the key-value pairs under the `[mysqld]` section as JSON for rapid analysis.

### Generating boilerplate config files
A team member designs a configuration structure in JSON. They pass this JSON back through your agent using the MCP to generate a perfectly formatted `.editorconfig` file, ready for commit.

### Comparing different environment configs
An engineer has development and production config files, both messy INI formats. The agent uses this MCP to convert both into standardized JSON objects, making programmatic comparison of differences straightforward.

## Benefits

- Stops data loss during format migration. The `parse_ini` tool handles sections and comments, ensuring no structural context is discarded when moving from INI to JSON.
- Manages complex configurations like those found in MySQL's `my.cnf`. You can reliably extract specific database settings by targeting defined sections within the raw file.
- Reduces manual copy-pasting errors. Instead of copying parameters between tabs or files, your agent converts the entire structure automatically.
- Supports diverse legacy systems. It reads and parses formats from Git configs, `php.ini`, and `.editorconfig`, making it useful for mixed-stack environments.
- Works both ways. If you get a JSON schema and need to generate a valid INI file for testing, the MCP handles the reverse conversion automatically.

## How It Works

The bottom line is: it guarantees accurate, bidirectional format translation for complex configuration files.

1. You provide the raw configuration text and specify the required direction: INI-to-JSON or JSON-to-INI.
2. The engine processes the input, interpreting sections, nested keys, and comments deterministically.
3. It returns a clean JSON object or a perfectly formatted INI string that maintains all original structural information.

## Frequently Asked Questions

**Does it preserve INI sections?**
Yes. INI sections like [database] become nested JSON objects and are fully restored when converting back to INI format.

**What config files does this work with?**
Any INI-format file: php.ini, my.cnf (MySQL), .editorconfig, Git config, Windows .ini files, and custom application configs.

**Does it handle comments?**
Yes. Lines starting with ; or # are treated as comments and properly handled during parsing. Comments are stripped from the JSON output.

**When should I use the `parse_ini` tool for JSON-to-INI conversions?**
Use it when your source data is structured as a JSON object, but you need the output in legacy INI format. The engine handles reversing the structure accurately. This is useful if an API gives you configuration data that needs to be written back into a standard config file.

**How does `parse_ini` handle nested keys like `database.host`?**
It treats them deterministically, preserving the hierarchy through dot notation. Whether converting to JSON or INI, it keeps track of the full key path. This means your structure remains intact even if you have deeply nested settings.

**How does the performance of `parse_ini` scale with large config files?**
Since it uses a robust, established parser, it maintains good performance across various file sizes. While extremely massive files might take time, its architecture is designed for reliable processing of real-world, enterprise-sized configs.

**If I give `parse_ini` an improperly formatted config, what error handling do I get?**
The tool provides specific errors pointing to the parsing failure location. Instead of failing silently, it flags syntax issues like missing equals signs or misplaced sections. This lets your agent pinpoint exactly where the input needs fixing.

**Why is `parse_ini` considered highly precise for config parsing?**
The engine relies on the same parser used by npm, which has been tested extensively in massive developer ecosystems. This deep integration guarantees it respects obscure syntax rules and edge cases found in common configuration formats.
