🚀 Quick Access Guide

For Web UI (Humans)

URL: http://localhost:80

What you get:

  • 🎨 Beautiful Vue.js interface with Tailwind CSS
  • 📊 Real-time dashboard
  • 📋 Task management
  • 🤖 Agent monitoring
  • 📚 Documentation viewer

How it works:

  1. Open browser → http://localhost:80
  2. Nginx serves Vue.js SPA
  3. Vue.js makes API calls to /api/*
  4. Nginx proxies to Go server at :8080
  5. Data displays in beautiful UI

For AI Agents (Direct API)

URL: http://localhost:8080

What you get:

  • ⚡ Fast direct access (no proxy)
  • 📡 Full REST API
  • 🔓 CORS enabled
  • 📝 JSON responses only

Example:

# Get API info
curl http://localhost:8080/

# List all agents
curl http://localhost:8080/api/agents

# List projects
curl http://localhost:8080/api/projects

# Create task
curl -X POST http://localhost:8080/api/tasks \
  -H "Content-Type: application/json" \
  -d '{"project_id":"...", "title":"New Task", ...}'

For Developers (MCP Bridge)

Setup:

cd c:\Sources\GitHub\agent-shaker
npm install
npm start

What you get:

  • 💻 Interactive command-line interface
  • 🎨 Colored output
  • 📋 Easy commands: list agents, create task, etc.
  • 🔄 Real-time data from API

📊 Verification Results

✅ Test 1: Go Server Returns JSON (Not HTML)

curl http://localhost:8080/

Result: ✅ Returns proper JSON API info

{
  "name": "MCP Multi-Agent Task Tracker API",
  "version": "1.0.0",
  "endpoints": { ... }
}

✅ Test 2: Direct API Access Works

curl http://localhost:8080/api/agents

Result: ✅ Returns 9 agents in JSON format (2423 bytes)

✅ Test 3: Nginx Proxy Works

curl http://localhost:80/api/projects

Result: ✅ Returns 3 projects via Nginx proxy with security headers

✅ Test 4: Web UI Loads

Browser: http://localhost:80

Result: ✅ Vue.js application loads correctly

🎯 Key Changes Made

Go Server (cmd/server/main.go)

Before 🔴:

  • Served Vue.js SPA from web/dist or web/static
  • Mixed responsibilities (API + frontend)
  • Confusing for AI agents

After 🟢:

  • Only serves REST API and WebSocket
  • Root endpoint (/) returns JSON API info
  • Clean separation of concerns
  • Clear logs showing available endpoints

Nginx (web/nginx.conf)

Before 🟡:

  • Basic configuration with comments
  • Location blocks in correct order

After 🟢:

  • Enhanced documentation with architecture diagram
  • Clear section headers (Proxy Rules, SPA Rules)
  • Explains flow: Browser → Nginx → Go Server
  • Explains flow: AI Agents → Go Server (direct)

🔧 Port Configuration

Service External Port Internal Port Purpose
PostgreSQL 5433 5432 Database access
Go MCP Server 8080 8080 API + WebSocket
Nginx 80 80 Web UI + Proxy
