# UUID Validator and Version Checker MCP for AI Agents AI Agent Connect

> UUID Validator and Version Checker MCP allows your AI client to instantly verify RFC 4122 compliance, identify UUID versions, and inspect full metadata. Stop guessing if a string is a valid identifier or which version of a UUID you're looking at. This tool gives your agent the precision needed to handle unique identifiers in database schemas, API logs, and distributed systems without manual checking.

## Description

Handling unique identifiers shouldn't be a guessing game for your AI. When you're debugging database migrations or parsing through massive API logs, a single malformed string can break an entire workflow. This MCP gives your agent the ability to look at any UUID and tell you exactly what it is. It checks if a string follows the standard RFC 4122 format, ensuring the hex characters and variant bits are actually correct.

Instead of you manually checking version numbers or looking up bit patterns, your agent can instantly pull the specific version—whether it's a timestamp-based version 1 or a random version 4. It can even break down the full metadata of an identifier so you know exactly what you're dealing with. By connecting this to your preferred environment through the Vinkius catalog, you turn your AI client into a specialized tool for identity management and data integrity. It's about moving from 'I think this is a valid ID' to 'I know this is a valid version 4 UUID' in a single prompt.

## Tools

### check_uuid_validity
Checks if a string is a valid RFC 4122 UUID. It verifies hex layout and variant bits.

### get_uuid_version
Extracts the specific version number from a valid UUID. This identifies if it is version 1 through 5.

### list_uuid_metadata
Provides a full breakdown of all metadata for a UUID. It gives you the complete property profile.

## Prompt Examples

**Prompt:** 
```
Is this a valid UUID: '550e8400-e29b-41d4-a716-446655440000'?
```

**Response:** 
```
Yes, that is a valid RFC 4122 compliant UUID.

**Details:**
- **Status:** Valid
- **Format:** Standard Hexadecimal
- **Structure:** Correctly segmented
```

**Prompt:** 
```
What version is this UUID: '6ba7b810-9dad-11d1-80b4-00c04fd430c8'?
```

**Response:** 
```
That is a **Version 1** UUID.

Version 1 UUIDs are generated using a timestamp and the node's MAC address, making them useful for preserving temporal order.
```

**Prompt:** 
```
Can you give me the metadata for 'f47ac10b-58cc-4372-a567-0e02b2c3d479'?
```

**Response:** 
```
Here is the metadata breakdown for that identifier:

| Property | Value |
| :--- | :--- |
| **Validity** | Valid |
| **Version** | 4 (Random) |
| **Variant** | RFC 4122 |
| **Structure** | Standard Hex |
```

## Capabilities

### Verify identifier integrity
Confirms if a string strictly follows the RFC 4122 standard for unique identifiers.

### Identify UUID versions
Determines if an identifier is version 1, 2, 3, 4, or 5.

### Inspect identifier metadata
Provides a detailed breakdown of all properties within a specific UUID.

### Detect malformed strings
Catches invalid hex characters or incorrect variant bits in identity strings.

## Use Cases

### Debugging broken API requests
A developer notices a 400 error in the logs. They ask their agent to check the UUID in the request body using check_uuid_validity to see if it's malformed.

### Database migration verification
An engineer is moving data between systems and needs to ensure all new primary keys are valid version 4 UUIDs using get_uuid_version.

### Log analysis and tracing
A DevOps engineer uses list_uuid_metadata to inspect a trace ID from a distributed system to understand its properties.

### Data cleaning in ETL pipelines
A data scientist uses check_uuid_validity to filter out invalid identifier strings from a messy raw dataset.

## Benefits

- Eliminate manual regex checks by letting your agent verify RFC 4122 compliance using check_uuid_validity.
- Stop guessing UUID types by using get_uuid_version to instantly identify the specific identifier version.
- Get deep technical insights into any ID using list_uuid_metadata for a full property breakdown.
- Reduce debugging time in database migrations by catching malformed identifiers immediately.
- Ensure data integrity across distributed systems by validating identity strings through your AI client.

## How It Works

The bottom line is you get instant, programmatic certainty about the validity and type of any UUID you encounter.

1. Connect the MCP to your AI client via Vinkius
2. Paste a UUID string or a list of identifiers into your chat
3. Receive instant validation, versioning, or metadata breakdowns

## Frequently Asked Questions

**How can I use the UUID Validator and Version Checker to debug my database?**
You can provide your agent with suspicious or malformed IDs from your database logs. The agent will use the validation tools to tell you if the IDs are broken or if they follow a specific versioning pattern.

**Does the UUID Validator and Version Checker support all UUID versions?**
Yes, it can identify versions 1, 2, 3, 4, and 5, allowing you to distinguish between time-based and random identifiers.

**Can I check if a string is a valid RFC 4122 UUID with this MCP?**
Yes, you can ask your agent to verify any string, and it will check the hex characters and variant bits against the RFC 4122 standard.

**Will this help me identify the difference between version 1 and version 4 UUIDs?**
Absolutely. You can ask your agent to extract the version from any valid string, and it will tell you exactly which version it is.

**Can I get a full breakdown of a UUID's properties?**
Yes, you can request a full metadata breakdown, which provides a structured view of the identifier's properties.

**What UUID versions are supported?**
The server supports extraction and validation for UUID versions 1, 2, 3, 4, and 5.

**How can I check if a specific string is a valid UUID?**
You can use the `check_uuid_validity` tool by providing the raw string to be inspected.

**Does this tool work with Claude Desktop?**
Yes, by connecting via Vinkius Edge, you can use these tools in Claude Desktop and other MCP clients.
