MCP server directory

Educational MCP server for math operations, statistics, visualization, and persistent workspaces. Built with FastMCP 2.0.

AI project intelligence MCP server. Tracks 300+ open-source AI projects across GitHub, PyPI, npm, HuggingFace, Docker Hub, and Hacker News. 47 MCP tools for discovery, comparison, trend analysis, and semantic search across AI repos, HuggingFace models/datasets, and public APIs.

Connect your own AI agent — Claude, ChatGPT, Cursor, and other MCP-compatible clients — directly to your CalendarBridge account. Your agent can read and manage your calendars, events, schedulers, and syncs on your behalf, with permissions you control. Bring Your Own Agent uses MCP (the Model Context Protocol) — an open standard that lets AI assistants connect to outside tools. CalendarBridge runs a hosted MCP server, so any MCP-capable client can connect to your account and act on your calendars for you.
