MCP Servers: AI’s Universal Connector
MCP (Model Context Protocol) is like USB-C for AI—a universal standard that lets AI systems connect with external tools, databases, and services.
Introduced by Anthropic in November 2024, MCP is how modern AI IDEs connect to the real world.
Why MCPs Matter
Without MCP, every time you wanted AI to work with a new tool:
- Custom code for each integration
- Different formats for different services
- Lots of fragmentation and bugs
With MCP, there’s ONE standard way for all connections.
What Can MCPs Do?
| Capability | Examples |
|---|---|
| Access files | Read/write to your computer |
| Query databases | Fetch data from PostgreSQL, Supabase |
| Use APIs | Weather, payments, social media |
| Control tools | Git, Slack, Google Services |
| Memory | Remember context across sessions |

Quick Example
Without MCP:
“Update the Q4 budget spreadsheet” AI: “I can’t access external files. You’ll need to do that manually.”
With MCP (Google Sheets connected):
“Update the Q4 budget spreadsheet” AI: “Done! I’ve updated cell B12 with the new projection.”
Where MCPs Are Used
- Cursor — Connect to databases, APIs, documentation
- Claude Desktop — Access local files, run commands
- Antigravity — Multi-agent tool access
- VS Code — Extensions using MCP protocol
