🔌 Model Context Protocol

Why it matters and when it works — A standard protocol connecting AI with external systems

❓ Why MCP is Needed

💥 Solving the M×N Problem

M × N
M AI apps × N tools
= Implementation explosion
→
M + N
M clients + N servers
= Unified by standard protocol
⚠️ Traditional Challenges
  • Fragmented integrations — Custom implementation required for each data source
  • Does not scale — Individual implementation needed for every AI when adding new tools
  • Information silos — AI isolated from external data
  • Increasing maintenance costs — Maintenance required for each connection
✅ MCP Solution
  • Standard protocol — Implement once, connect to entire ecosystem
  • Plug and play — Add MCP server and use immediately
  • Bidirectional connection — Standardized data retrieval and action execution
  • Open source — Vendor-agnostic, anyone can use and contribute

💡 Example

Connections to Google Drive, Slack, GitHub, PostgreSQL etc. are provided as common MCP servers rather than dedicated connectors. AI apps only need to implement an MCP client once to communicate with all MCP servers.
