  • mcp-demo: Interactive prompt that guides users through database operations
    • Required argument: topic - The business domain to analyze
    • Generates appropriate database schemas and sample data
    • Guides users through analysis and insight generation
    • Integrates with the business insights memo
Tools

The server offers six core tools:

Query Tools

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
