+MCP is a protocol that enables secure connections between host applications, such as [Claude Desktop](https://claude.ai/download), and local services. In this quickstart guide, you'll learn how to:
- Set up a local SQLite database
- Connect Claude Desktop to it through MCP
- Query and analyze your data securely
-While this guide focuses on using Claude Desktop as an example MCP client, the protocol is open and can be implemented by any application. IDEs, AI tools, and other software can all act as MCP clients to access local integrations in a standardized way.
