# Semantic Versioning Checker MCP for AI Agents AI Agent Connect

> Semantic Versioning Checker MCP for precise SemVer 2.0.0 validation and comparison. It lets your AI agent verify version strings, determine precedence between releases, and sort version lists according to strict Semantic Versioning rules, including pre-release and build metadata handling.

## Description

Managing software release cycles often involves messy version strings that break automated scripts or deployment pipelines. This MCP gives your AI agent a reliable way to handle Semantic Versioning 2.0.0 without guessing. Instead of your agent trying to eyeball whether a beta release comes before a stable one, it can perform exact mathematical comparisons. You can use it to check if a version string is actually valid or to organize a messy list of releases into the correct order. It handles the tricky parts of the spec, like pre-release precedence and build metadata, so your agent doesn't make mistakes that lead to broken dependencies. By connecting this to your workflow through the Vinkius catalog, you ensure that every versioning decision your agent makes is technically sound and follows industry standards.

## Tools

### compare_versions
Determines the precedence relationship between two SemVer versions. It ignores build metadata to follow standard rules.

### list_precedence_order
Returns a sorted list of unique version strings. It organizes them based on strict SemVer precedence.

### parse_version
Validates a SemVer 2.0.0 string. It extracts all individual components for easy analysis.

## Prompt Examples

**Prompt:** 
```
Is '1.0.0-beta.1' a valid SemVer string?
```

**Response:** 
```
Yes, **1.0.0-beta.1** is a valid Semantic Versioning 2.0.0 string.

It follows the standard format:
* **Major**: 1
* **Minor**: 0
* **Patch**: 0
* **Pre-release**: beta.1
```

**Prompt:** 
```
Which version is higher: 1.2.3 or 1.2.3-rc.1?
```

**Response:** 
```
The higher version is **1.2.3**.

According to SemVer rules, a stable version always has higher precedence than a pre-release version of the same major, minor, and patch numbers.
```

**Prompt:** 
```
Sort these versions: 2.0.0, 1.0.0, 1.0.0-alpha
```

**Response:** 
```
Here is the sorted list in ascending order:

1.  `1.0.0-alpha`
2.  `1.0.0`
3.  `2.0.0`
```

## Capabilities

### Validate version strings
Check if a version string follows the SemVer 2.0.0 specification.

### Compare release precedence
Determine exactly which version is newer or older based on official rules.

### Sort version lists
Organize a collection of version strings into a correct chronological order.

### Extract version components
Break a version string down into its major, minor, patch, and pre-release parts.

## Use Cases

### Automating CI/CD pipeline checks
A developer asks their agent to check if a new build tag is valid before it hits production, using parse_version to verify the format.

### Sorting release histories
A release manager provides a messy list of version numbers and asks the agent to sort them correctly using list_precedence_order.

### Dependency conflict resolution
An engineer needs to know if version 1.2.3-beta is older than 1.2.3, so they use compare_versions to get a definitive answer.

### Validating configuration files
An agent scans a manifest file to ensure all listed software versions strictly adhere to the SemVer 2.0.0 standard.

## Benefits

- Eliminate versioning errors by using parse_version to catch invalid strings immediately.
- Automate release ordering using list_precedence_order to keep your documentation accurate.
- Ensure deployment logic is sound by using compare_versions to check version precedence.
- Stop manual regex writing for version strings by letting the agent handle the parsing.
- Maintain strict SemVer 2.0.0 compliance across all your automated software workflows.

## How It Works

The bottom line is your agent stops guessing about version numbers and starts following the spec perfectly.

1. Connect the MCP to your preferred AI client via Vinkius.
2. Ask your agent to validate, compare, or sort specific version strings.
3. Receive precise, rule-compliant results for your deployment or documentation tasks.

## Frequently Asked Questions

**How can I use Semantic Versioning Checker to validate my release tags?**
You can ask your AI agent to check any version string. It will tell you immediately if the string follows the SemVer 2.0.0 standard or if it contains errors.

**Can this Semantic Versioning Checker handle pre-release versions like beta or rc?**
Yes. It is specifically designed to handle the complexities of pre-release precedence, ensuring that beta and release candidate versions are compared correctly against stable releases.

**Will the Semantic Versioning Checker help me sort my software versions?**
Absolutely. You can provide a list of version strings, and your agent will return them in the correct chronological order based on official precedence rules.

**Does the Semantic Versioning Checker ignore build metadata during comparison?**
Yes. Following the SemVer 2.0.0 spec, build metadata is ignored when determining the precedence between two versions.

**Can I use this Semantic Versioning Checker with my existing AI coding tools?**
Yes, once you connect it via Vinkius, you can use it within any MCP-compatible client like Claude, Cursor, or VS Code.

**Does this tool support build metadata?**
Yes, `parse_version` extracts build metadata, though it is ignored during precedence comparisons as per the SemVer 2.0.0 specification.

**How are pre-release versions handled?**
Pre-release versions are handled according to strict SemVer rules. For example, `1.0.0-alpha` is considered lower precedence than `1.0.0` when using `compare_versions`.

**Can I sort multiple versions at once?**
Yes, you can use `list_precedence_order` to provide an array of version strings and receive them sorted from lowest to highest precedence.
