MCP Dependency Resolver v1.0

Purpose

Proactively analyze, validate, and resolve MCP server dependencies BEFORE installation to prevent the common "missing dependency" failures that plague MCP ecosystems.

Auto-Activation Triggers

This skill activates when:

• User wants to install a new MCP server
• User mentions MCP server names or GitHub repos
• User asks about MCP compatibility
• User experiences MCP connection failures
• Installing ANY MCP from GitHub/NPM/PyPI

Core Capabilities

1. Dependency Detection

• Scans package.json for Node.js dependencies
• Analyzes pyproject.toml, requirements.txt, setup.py for Python deps
• Detects UV, NPM, Pip, Poetry, Cargo requirements
• Identifies system-level dependencies (Git, Visual Studio Build Tools)

2. Pre-Installation Validation

• Checks if UV is installed (common failure point)
• Verifies Node.js version compatibility
• Validates Python version requirements
• Tests PATH configurations
• Confirms write permissions for installation directories

3. Auto-Remediation

• Installs UV automatically if missing
• Updates NPM/Pip to required versions
• Adds missing PATH entries
• Creates necessary directories
• Sets up virtual environments when needed

4. Compatibility Analysis

• Windows-specific compatibility checks
• Claude Desktop version validation
• MCP protocol version verification
• Conflict detection with existing servers

Workflow

User Request → Parse MCP Source → Fetch Metadata → Analyze Dependencies
    ↓
Check Installed Tools → Identify Gaps → Auto-Install Missing
    ↓
Validate Configuration → Test Connectivity → Report Status
    ↓
Install MCP Server → Verify Connection → Success!

Usage Examples

Example 1: GitHub MCP Installation

User: "Install the Android MCP server from GitHub"

Claude:
1. Fetches https://github.com/cursortouch/android-mcp
2. Analyzes pyproject.toml: requires uv, python 3.10+
3. Checks system: UV not found ❌
4. Auto-installs: pip install uv --break-system-packages ✅
5. Validates: uv 0.10.2 installed ✅
6. Proceeds with MCP installation

Example 2: NPM Package MCP

User: "Add @modelcontextprotocol/server-filesystem"

Claude:
1. Checks NPM registry metadata
2. Requires: Node.js >= 18.0.0
3. Validates: Node v20.11.0 installed ✅
4. Checks: NPM 10.2.4 installed ✅
5. Installs MCP directly (no missing deps)

Example 3: Preventive Check

User: "Can I install the Docker MCP?"

Claude:
1. Analyzes Docker MCP requirements
2. Needs: Docker Desktop, Node.js 18+
3. Checks: Docker Desktop not running ⚠️
4. Recommends: Start Docker Desktop first
5. Waits for user confirmation before proceeding

Integration with Claude Desktop

Configuration File Path

C:\Users\micha\AppData\Roaming\Claude\Claude Extensions Settings\

Pre-Installation Checklist

• UV installed at C:\DevToolsPython313\Scripts\uv.exe
• Node.js >= 18.0.0
• Python >= 3.10
• Git for Windows
• NPM globals directory writable
• Claude Desktop version 1.1.3149.0+

Dependency Knowledge Base

Python MCP Servers

Required:

• UV (Astral package manager)
• Python 3.10+
• pip with --break-system-packages flag

Common packages:

• fastmcp, mcp, anthropic-mcp, pydantic

Installation pattern:

uv --directory "path" run server-name

Node.js MCP Servers

Required:

• Node.js 18.0.0+
• NPM 9.0.0+

Common packages:

• @modelcontextprotocol/sdk
• @anthropic-ai/sdk

Installation pattern:

npx -y package-name

Built-in MCP Servers

No dependencies required:

• Filesystem (built into Claude Desktop)
• These use Claude Desktop's bundled Node.js

Error Prevention Patterns

Pattern 1: Missing UV

Error signature: spawn uv ENOENT Prevention: Check UV before Python MCP installation Auto-fix: python -m pip install uv --break-system-packages

Pattern 2: Node Version Mismatch

Error signature: engines.node requirement not satisfied Prevention: Validate Node version against package.json Auto-fix: Prompt user to update Node.js

Pattern 3: Permission Errors

Error signature: EACCES: permission denied Prevention: Test write permissions to target directories Auto-fix: Use user-scoped installations, avoid global when possible

Pattern 4: PATH Issues

Error signature: command not found after installation Prevention: Verify PATH includes installation directories Auto-fix: Add to user PATH, provide session-specific workarounds

Automated Dependency Matrix

MCP Server Type	UV	Node	Python	Git	Special
