## Description

This MCP provides a deterministic engine for resolving complex dependency trees. It uses depth-first search with backtracking to ensure version compatibility, detect circular dependencies, and handle diamond dependencies. Use `resolve_dependencies` to calculate the resolution order and tree, `validate_constraint` to check SemVer compliance, and `check_graph_integrity` to verify the resulting structure is a valid Directed Acyclic Graph.

## Tools

### check_graph_integrity
Analyzes a resolved dependency tree to identify potential structural risks

### resolve_dependencies
Performs the primary deterministic resolution of a dependency tree based on root requirements

### validate_constraint
Checks if a specific package version satisfies a given semantic versioning constraint

## Prompt Examples

**Prompt:** 
```
Resolve these dependencies: root requires pkg-a@^1.0.0 and pkg-b@~2.1.0, where pkg-a depends on pkg-c@1.0.0.
```

**Response:** 
```
The resolved dependency tree includes pkg-a (1.0.0), pkg-b (2.1.5), and pkg-c (1.0.0). The resolution order is pkg-c, pkg-a, pkg-b.
```

**Prompt:** 
```
Check if version 1.2.3 satisfies the constraint ^1.2.0.
```

**Response:** 
```
Yes, version 1.2.3 satisfies the constraint ^1.2.0.
```

**Prompt:** 
```
Is this dependency tree valid and free of circularities?
```

**Response:** 
```
The integrity check passed. No circular dependencies or conflicts were detected in the resolved tree.
```

## Frequently Asked Questions

**How does the engine handle version conflicts?**
The engine uses a backtracking algorithm. If a version constraint cannot be satisfied, it retreats to the previous decision point to attempt a different version that satisfies all active constraints.

**What is a diamond dependency?**
A diamond dependency occurs when two different packages depend on the same third package. The engine ensures the third package is resolved only once and that its version satisfies both parent requirements.

**Can I detect circular dependencies?**
Yes, you can use `check_graph_integrity` to analyze a resolved tree and identify if any circular dependencies exist within the structure.
