Project Management MCP servers for work planning, organization, and progress tracking including: task management systems, sprint planning, project roadmaps and timelines, resource allocation and scheduling, milestone tracking, team capacity planning, workflow management, project collaboration, status reporting, and portfolio management.

Excludes: real-time communication tools, instant messaging, and video conferencing platforms.

Computer and Web Automation MCP servers for automated execution and orchestration across applications and web platforms including: robotic process automation (RPA), web scraping and browser automation, workflow automation, task scheduling and cron jobs, API orchestration and integration platforms, bot development, and scripted task execution. Focus is on action-taking rather than data movement.

Excludes: pure data pipeline tools and search indexing systems.

LLM Orchestration MCP servers specifically designed for managing and orchestrating Large Language Models including: prompt engineering and management tools, AI agent frameworks, model routing and load balancing, AI safety implementations and guardrails, multi-agent coordination systems, LLM workflow orchestration, model fine-tuning platforms, and AI-powered automation systems.

Excludes: general chat applications unless specifically LLM-focused or AI-centric.

Messaging & Collaboration MCP servers for human-to-human communication and teamwork platforms including: instant messaging and chat systems, voice and video conferencing, team channels and workspaces, collaborative document editing, notification systems, discussion forums, file sharing, screen sharing, and internal communication tools.
