mcp-server-toolkit 0.1.0

9 production-ready MCP servers for AI assistants — database, files, git, monitoring, tasks, email, Slack, calendar + CLI discovery

MCP Toolkit

9 production-ready MCP (Model Context Protocol) servers + CLI discovery tool + Streamlit playground.

MCP is the open standard for connecting AI assistants to external tools. This toolkit provides ready-to-use servers covering common development workflows: database operations, file management, knowledge search, system monitoring, git analytics, and task tracking.

What This Solves

• Slow tool integration — Stand up MCP servers in minutes instead of weeks
• Fragmented workflows — One toolkit for data, files, git, monitoring, and tasks
• Weak governance — Consistent server specs and auto-discovery for safer deployments
