MCP Social Network

# MCP Social Network - Product Requirements Document ## Overview **Product Name:** MCP Feed (Model Context Protocol Social Network) **Target Demo Date:** Next week (Microsoft Demo) **Core Concept:** A social network accessible exclusively through coding agents via MCP, enabling developers to share updates, follow each other, and interact within their development environment. ## Vision Create the first social network that exists entirely within the developer workflow, accessible only through AI coding agents. Users share coding insights, project updates, and development experiences without leaving their IDE or terminal. ## Core Value Proposition - **Zero Context Switching:** Social interactions happen within your coding environment - **Developer-Focused:** Content naturally revolves around coding, projects, and technical insights - **Agent-Native:** Designed for AI-mediated interactions, not traditional UI - **Viral Potential:** Novel interaction model that showcases MCP capabilities ## Target Users - **Primary:** Developers using AI coding agents (Claude, GPT, etc.) - **Secondary:** Tech influencers and early adopters interested in novel social platforms - **Demo Audience:** Microsoft teams evaluating MCP technology ## Core Features ### 1. User Management - **Create Profile:** `create_profile(username, bio)` - **View Profile:** `get_profile(username)` - **Update Bio:** `update_profile(bio)` - **User Discovery:** `search_users(query)` ### 2. Social Graph - **Follow Users:** `follow_user(username)` - **Unfollow Users:** `unfollow_user(username)` - **View Followers:** `get_followers(username)` - **View Following:** `get_following(username)` - **Suggested Users:** `get_suggested_users()` (based on mutual follows) ### 3. Content Creation - **Post Update:** `post_update(text, tags?)` - 280 character limit - Optional tags for categorization (#javascript, #ai, #debugging) - **Share Code Snippet:** `post_code(code, language, description)` - **Share Achievement:** `post_achievement(title, description)` (e.g., "Just shipped my first React app!") ### 4. Content Consumption - **Personal Feed:** `get_feed(limit?)` - Posts from followed users - **Global Feed:** `get_global_feed(limit?)` - All public posts - **User Posts:** `get_user_posts(username, limit?)` - **Tag Feed:** `get_tag_posts(tag, limit?)` ### 5. Interactions - **Like Post:** `like_post(post_id)` - **Reply to Post:** `reply_to_post(post_id, text)` - **Mention User:** `mention_user(username, text)` (creates notification) - **Repost:** `repost(post_id, comment?)` ### 6. Notifications - **Get Notifications:** `get_notifications()` - New followers - Mentions - Replies to your posts - Likes on your posts - **Mark as Read:** `mark_notifications_read()` ## Technical Architecture ### Database Schema (Supabase) ```sql -- Users table users ( id uuid primary key, username text unique not null, bio text, created_at timestamp, follower_count integer default 0, following_count integer default 0 ) -- Posts table posts ( id uuid primary key, user_id uuid references users(id), content text not null, code text, language text, tags text[], like_count integer default 0, reply_count integer default 0, created_at timestamp ) -- Follows table follows ( follower_id uuid references users(id), following_id uuid references users(id), created_at timestamp, primary key (follower_id, following_id) ) -- Likes table likes ( user_id uuid references users(id), post_id uuid references posts(id), created_at timestamp, primary key (user_id, post_id) ) -- Replies table replies ( id uuid primary key, post_id uuid references posts(id), user_id uuid references users(id), content text not null, created_at timestamp ) -- Notifications table notifications ( id uuid primary key, user_id uuid references users(id), type text not null, -- 'follow', 'mention', 'reply', 'like' from_user_id uuid references users(id), post_id uuid references posts(id), read boolean default false, created_at timestamp ) ``` ### MCP Server Stack - **Runtime:** Node.js with TypeScript - **Database:** Supabase (PostgreSQL) - **Authentication:** Simple username-based (for demo) - **MCP Framework:** Official MCP SDK ### Authentication Strategy - **Demo Version:** Username-only (no passwords) - **Production:** API keys or OAuth integration - **User Context:** Each MCP session maintains current user state ## User Experience Design ### Typical User Journey 1. **Setup:** Add MCP server to coding agent configuration 2. **Onboarding:** `create_profile("alice_codes", "Full-stack dev building AI tools")` 3. **Discovery:** `search_users("react")` → `follow_user("bob_react")` 4. **Daily Use:** - Morning: `get_feed()` to see what friends are working on - During coding: `post_update("Debugging a tricky async issue with promises...")` - Evening: `get_notifications()` to see responses ### Sample Interactions ``` User: "show me my MCP feed" Agent: 📱 MCP Feed (3 new notifications) @alice_codes (2h ago) 🔥 trending "Just built a Chrome extension that automatically generates commit messages using Claude.

Agent: ✅ Posted update ``` ## Success Metrics ### Demo Success - [ ] 5+ demo users actively posting - [ ] 20+ posts created during demo - [ ] All core features working smoothly - [ ] Positive reaction from Microsoft audience ### Engagement Metrics - Daily active users - Posts per user per day - Follow/follower ratios - Notification engagement rates ## Technical Requirements ### Performance - Feed loading: < 2 seconds - Post creation: < 1 second - Support 100+ concurrent users (demo scale) ### Reliability - 99% uptime during demo period - Graceful error handling for all MCP functions - Data persistence and backup ### Security - Input validation and sanitization - Rate limiting on post creation - Content moderation (basic profanity filter) ## Implementation Timeline ### Phase 1: Core Infrastructure (Days 1-2) - [x] Set up Supabase database - [ ] Create basic MCP server structure - [ ] Implement user management functions - [ ] Basic post creation and retrieval ### Phase 2: Social Features (Days 3-4) - [ ] Follow/unfollow functionality - [ ] Feed generation algorithm - [ ] Likes and replies system - [ ] Notifications system ### Phase 3: Polish & Demo Prep (Days 5-7) - [ ] Error handling and validation - [ ] Performance optimization - [ ] Demo data setup - [ ] Documentation and setup guides - [ ] Integration testing ## Risk Mitigation ### Technical Risks - **Supabase Rate Limits:** Implement caching and optimize queries - **MCP Server Stability:** Extensive error handling and fallbacks - **Database Performance:** Proper indexing and query optimization ### Demo Risks - **User Adoption:** Pre-populate with engaging demo content - **Technical Issues:** Have backup scenarios and fallback plans - **Feature Complexity:** Focus on core MVP features only ## Future Enhancements (Post-Demo) - Rich media support (images, code screenshots) - Direct messaging between users - Trending posts and topics - Integration with GitHub/GitLab for automatic achievement posts - Advanced search and filtering - User verification system - Mobile app companion - Analytics dashboard for users ## Success Definition The MCP Social Network demo is successful if: 1. All core features work reliably during the Microsoft demo 2. Demo users actively engage with the platform 3. The audience understands and appreciates the novel interaction model 4. The demo generates interest in MCP technology 5. We can show clear viral potential and developer adoption path --- *This PRD serves as the foundation for building the MCP Social Network demo. Focus should remain on the core MVP features needed for a compelling demo experience.*
