MCP (Model Context Protocol): The Future of AI Tool Integration
Model Context Protocol (MCP) standardizes how AI applications connect to data sources and tools-filesystems, databases, APIs, and IDEs speak a common protocol.
Why MCP Matters
Before MCP, every agent framework invented its own plugin format. MCP provides discoverable tools and resources with typed schemas-like LSP for AI tools.
Architecture
- Host - Cursor, Claude Desktop, custom agent
- MCP Server - Exposes tools (
query_db,read_file) and resources - Transport - stdio or SSE
Developers implement servers once; any MCP-compatible host can use them.
Building a Simple Server
Expose tools with clear descriptions-the model chooses based on names and docstrings. Validate inputs server-side; never trust the LLM to sanitize SQL.
Security
Run servers with least privilege. Audit tool calls. Sandbox filesystem access to project roots.
Conclusion
MCP is the USB-C moment for AI integrations. Invest in small, focused MCP servers for your internal systems rather than bespoke agent plugins per IDE.
