# TOML Parser & Validator MCP for AI Agents AI Agent Connect

> TOML Parser & Validator MCP provides high-precision tools for handling TOML configuration files. It converts raw TOML strings into structured data, validates objects against specific schemas, and pinpoints the exact line and column of any syntax errors to make debugging configuration files effortless.

## Description

Managing configuration files shouldn't feel like hunting for a needle in a haystack. When you're working with TOML, a single missing quote or a misplaced bracket can break an entire deployment or application. This MCP changes that by giving your AI client the ability to read, structure, and verify your configuration data with mathematical precision. Instead of guessing why a file won't load, you can have your agent instantly convert raw text into usable data structures or check if your settings match a required template. If something is broken, you won't have to scan hundreds of lines of code; you'll get the exact location of the mistake immediately. It's a reliable way to ensure your settings stay consistent and error-free. By connecting this to your workflow through the Vinkius catalog, you're adding a layer of strict data integrity that keeps your configuration management predictable and fast.

## Tools

### locate_syntax_error
Finds the exact line and column of a parsing failure. This helps you fix broken TOML files instantly.

### parse_toml_string
Converts a raw TOML string into a structured object. It automatically catches duplicate keys or invalid syntax.

### validate_schema
Checks if a parsed TOML object matches your required types and structure. It ensures your data stays consistent.

## Prompt Examples

**Prompt:** 
```
Can you check if this TOML string is valid and tell me if there are any errors?
```

**Response:** 
```
I've checked the TOML string you provided. 

**Status:** ✅ Valid

No syntax errors or duplicate keys were found. The structure is clean and ready to use.
```

**Prompt:** 
```
I think I have a typo in my config. Can you find where it is?
```

**Response:** 
```
I found a syntax error in your configuration:

| Location | Error Type | Description |
| :--- | :--- | :--- |
| **Line 4, Column 12** | `SyntaxError` | Unclosed quotation mark |

Please check the value on line 4 to fix the issue.
```

**Prompt:** 
```
Does this configuration match a schema where 'version' must be an Integer and 'enabled' must be a Boolean?
```

**Response:** 
```
I've validated the object against your schema requirements.

**Result:** ❌ Validation Failed

**Details:**
* `version`: Expected `Integer`, but found `String`.
* `enabled`: Expected `Boolean`, but found `String`.
```

## Capabilities

### Convert raw text to data
Turn unformatted TOML strings into structured objects your agent can actually use.

### Enforce data structures
Check that your configuration values match specific types like integers, strings, or booleans.

### Pinpoint syntax mistakes
Find the exact line and column where a configuration error occurred.

### Prevent duplicate keys
Catch accidental key repetitions that would otherwise corrupt your settings.

### Verify schema compliance
Ensure complex configuration objects follow a strict structural template.

## Use Cases

### Fixing broken deployment configs
A developer has a broken CI/CD pipeline due to a typo in a TOML file. They ask their agent to find the error, and it points to the exact line.

### Validating environment settings
An engineer needs to ensure a new set of environment variables matches the required schema. The agent runs a check and confirms everything is correct.

### Automating config generation
A user asks their agent to generate a new configuration file and immediately validates it to ensure it's perfectly formatted.

### Cleaning up legacy files
A team is migrating old settings to a new format and uses the agent to verify that all new TOML files adhere to the new structural rules.

## Benefits

- Stop wasting time hunting for typos in large configuration files using locate_syntax_error.
- Ensure data integrity by checking every setting against a template with validate_schema.
- Convert messy text into clean, usable data structures using parse_toml_string.
- Prevent deployment failures by catching duplicate keys before they reach production.
- Get immediate feedback on configuration errors instead of waiting for an application to crash.

## How It Works

The bottom line is you get a reliable way to validate and structure TOML data without manual checking.

1. Connect the MCP to your preferred AI client via Vinkius.
2. Provide the raw TOML string or the schema you want to check against.
3. Receive structured data or a precise error report indicating the exact location of any syntax issues.

## Frequently Asked Questions

**How can I use the TOML Parser & Validator MCP to find errors in my files?**
You can provide any TOML string to your agent, and it will use the built-in tools to pinpoint the exact line and column where a syntax error occurs, making it easy to fix.

**Can this TOML Parser & Validator MCP help me enforce specific data types?**
Yes. You can define a schema with expected types like Integer, String, or Boolean, and the agent will verify that your configuration matches those rules perfectly.

**Will the TOML Parser & Validator MCP catch duplicate keys in my settings?**
Absolutely. The parsing process automatically detects and flags any duplicate keys, preventing configuration conflicts before they cause issues.

**Is the TOML Parser & Validator MCP compatible with my existing AI tools?**
Yes, this MCP works with any compatible client like Claude, Cursor, or Windsurf, allowing you to bring strict TOML validation into your current workflow.

**Can I use the TOML Parser & Validator MCP for automated testing?**
Yes. You can use it to programmatically verify that generated configuration files adhere to your required structural templates and data types.

**How does the parser handle different TOML types?**
The `parse_toml_string` tool strictly maps TOML values to their corresponding types, including Integers, Floats, Booleans, Datetimes, Strings, Arrays, and Tables.

**Can I validate that my TOML matches a specific structure?**
Yes, you can use `validate_schema` to check if a parsed object conforms to your required keys and types.

**What happens if my TOML file has a syntax error?**
If parsing fails, you can use `locate_syntax_error` to find the exact line and column number where the error occurred.
