# Semantic Version Compatibility Checker MCP for AI Agents MCP

> Semantic Version Compatibility Checker verifies if a target version satisfies semver constraints like caret or tilde. It identifies major version bumps that introduce breaking changes, helping you manage dependencies without breaking your builds.

## Description

Imagine you are running an automated script to update all your project dependencies. You want everything to stay current, but the last thing you need is a broken build because a minor update actually introduced a breaking change. This MCP acts as a safety net for your dependency management. It looks at your existing constraints and compares them against new versions to see if they actually fit. Instead of manually checking every changelog, you can let your agent handle the heavy lifting. You'll find it easy to connect this to your workflow through the Vinkius catalog, where you can manage all your automation tools in one place. It catches those major version bumps before they hit your production environment, so you don't have to deal with emergency rollbacks.

## Tools

### check_compatibility
Analyzes two versions against semver rules to find breaking changes. It tells you exactly if an update is safe or risky.

## Prompt Examples

**Prompt:** 
```
Is it safe to move from 1.2.3 to 2.0.0 using the ^1.2.3 constraint?
```

**Response:** 
```
No, that is not safe. Upgrading to 2.0.0 is a major version bump, which breaks the `^1.2.3` rule.
```

**Prompt:** 
```
Check if 1.2.5 works with ~1.2.0.
```

**Response:** 
```
Yes, it does. Since 1.2.5 stays within the same minor version range, it satisfies the tilde constraint.
```

**Prompt:** 
```
Will upgrading to 1.3.0 break my current 1.2.0 installation under ^1.2.0?
```

**Response:** 
```
No, you are good. The `^1.2.0` constraint allows for minor and patch updates that do not introduce breaking changes.
```

## Capabilities

### Detect breaking changes
Identifies when a new version introduces incompatible changes that will break your code.

### Evaluate semver constraints
Checks if specific versions satisfy caret or tilde requirements automatically.

### undefined
undefined

### Analyze dependency updates
Provides a clear breakdown of whether an upgrade is safe to apply.

### Prevent build failures
Stops automated processes from applying versions that violate your project rules.

## Use Cases

### Preventing broken builds during automated updates
An engineer sets up a script to update npm packages, and the agent uses this MCP to block any version that breaks the current caret constraint.

### Verifying library upgrades in large monorepos
A developer needs to move from version 1.2.0 to 1.5.0 and asks their agent if the tilde constraint will allow it without issues.

### Auditing third-party dependencies for risk
During a security audit, an engineer uses the MCP to check if recent patch releases in their dependency tree introduced any unexpected major version shifts.

## Benefits

- Stop accidental breakage by catching major version bumps before they are applied.
- Automate your dependency audits using this tool.
- Reduce manual changelog reviews by letting your agent evaluate constraints.
- Maintain stable CI/CD pipelines with reliable version verification.
- Speed up package upgrades by instantly identifying safe patch and minor updates.

## How It Works

The bottom line is you stop guessing if an update will break your build.

1. Connect your preferred AI client to the MCP via Vinkius.
2. Provide a current version and a target version along with your semver constraints.
3. Get a clear answer on whether the update is compatible or contains breaking changes.

## Frequently Asked Questions

**How can the Semantic Version Compatibility Checker prevent broken builds?**
It identifies major version bumps that violate your existing constraints, allowing you to block risky updates before they reach production.

**Can I use Semantic Version Compatibility Checker with npm or Cargo?**
Yes, it works with any system using standard semver rules, including npm, Cargo, and Composer.

**Does the Semantic Version Compatibility Checker handle caret and tilde constraints?**
It specifically evaluates both `^` and `~` symbols to tell you if a target version stays within your allowed range.

**Will the Semantic Version Compatibility Checker help with automated dependency updates?**
Absolutely. You can integrate it into your automation workflows to automatically verify every package update for compatibility.

**Is the Semantic Version Compatibility Checker useful for large monorepos?**
Yes, it is great for checking multiple dependencies at once to ensure that a single upgrade does not cause a cascade of breaking changes across your project.

**How can I check if an upgrade is safe?**
You can use the `check_compatibility` tool by providing your current version, the target version, and the constraint (e.g., '^1.2.0'). The tool will return a boolean indicating if it is compatible.

**Does this tool detect breaking changes?**
Yes. The `check_compatibility` tool specifically flags major version bumps as breaking changes, helping you avoid incompatible updates.

**What constraints are supported?**
The tool supports caret (^), tilde (~), and exact version strings for precise compatibility analysis.
