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

Pre-Installation Checklist
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
