Claude Skills vs MCP: Differences and How to Choose
Both Claude Skills and Model Context Protocol (MCP) extend Claude's capabilities, but serve different purposes.
Quick Comparison
| Feature | Claude Skills | MCP | |---------|---------------|-----| | Purpose | Task automation | External data integration | | Complexity | Simple (file-based) | Complex (server-based) | | Deployment | Load folder | Run server | | Use Case | Workflows & automation | API & database access | | Latency | Low | Higher (network calls) |
Claude Skills
What it is: Self-contained automation packages with instructions and code.
Best for:
- Document processing workflows
- Data transformations
- Repeated task automation
- Internal logic
Example: PDF extraction skill that parses documents locally.
Model Context Protocol (MCP)
What it is: Protocol for connecting Claude to external systems via servers.
Best for:
- Database queries
- API integrations
- Real-time data access
- External system control
Example: MCP server connecting to PostgreSQL database.
When to Use Skills
✅ Self-contained workflows ✅ No external dependencies ✅ Frequent execution ✅ Low latency required
When to Use MCP
✅ External data needed ✅ Database integration ✅ API calls required ✅ Real-time updates
Can They Work Together?
Yes! Use Skills for workflow logic, MCP for data access:
MCP Server (data) → Claude → Skills (processing) → Output
