Vaali

Vaali is a comprehensive MCP server implementation that demonstrates the full spectrum of MCP capabilities including resources, prompts, tools, and official elicitation workflows. Built by ushakrishnan, it provides access to configuration files and sample data through resources, offers reusable prompt templates for code review and documentation generation, and implements both basic tools (weather, calculations, text analysis) and advanced elicitation-enabled tools that can interactively collect missing parameters from users. The server showcases official MCP elicitation patterns for tools like weather lookup, email sending, and calendar event creation, making it particularly useful as a learning reference for developers building MCP integrations or as a foundation for applications requiring interactive parameter collection workflows.
