A native MCP (Model Context Protocol) server built with Go that provides access to developer conference CFPs from developers.events.

🚀 Quick Start

Try it Now - Public Instance

No installation needed! Connect to the public hosted instance:

Claude Desktop Config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "developer-events": {
      "url": "https://developer-events-mcp-54127830651.europe-west2.run.app"
    }
  }
}

Restart Claude Desktop and start asking about CFPs!

---

This server can run in two modes:

Mode 1: Local (stdio) - For Claude Desktop

1. Configure Claude Desktop

Add to your Claude Desktop config:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "developer-events": {
      "command": "/full/path/to/mcp-server"
    }
  }
}

1. Restart Claude Desktop

2. Start Using!

Try these queries:

• "What CFPs are closing in the next 7 days?"
• "Show me Java-related conferences with open CFPs"
• "Find CFPs for conferences in France"
• "List AI conference CFPs closing this week"

Mode 2: HTTP Server - For Cloud Deployment

Deploy as a web service that anyone can connect to without installing anything!

Deploy to Google Cloud Run

1. Build and push the container:

# Set your GCP project
gcloud config set project YOUR_PROJECT_ID

# Build and deploy in one command
gcloud run deploy developer-events-mcp \
  --source . \
  --platform managed \
  --region us-central1 \
  --allow-unauthenticated \
  --memory 256Mi

1. Get your service URL:

gcloud run services describe developer-events-mcp --region us-central1 --format 'value(status.url)'

1. Connect from Claude Desktop:

Update your config to use your deployed endpoint (or use the public instance at the top of this README):

{
  "mcpServers": {
    "developer-events": {
      "url": "https://your-service-url.run.app"
    }
  }
}

Local HTTP Mode

Run locally as HTTP server for testing:

MODE=http PORT=8080 ./mcp-server
# Or let Cloud Run set PORT automatically
PORT=8080 ./mcp-server

Docker Build

docker build -t developer-events-mcp .
docker run -p 8080:8080 developer-events-mcp

🛠️ Building from Source

Prerequisites

• Go 1.21 or later

Build for Current Platform

go build -ldflags="-s -w" -o developer-events-mcp main.go

Build for All Platforms

./build-all.sh

This creates binaries in bin/ for:

• Linux (x86_64, ARM64)
• macOS (Intel, Apple Silicon)
• Windows (x86_64)

📊 Performance

Metric	Value
Binary Size	~7MB
Startup Time	<10ms
Memory Usage	~10-20MB
Runtime Dependencies	NONE

🏗️ Architecture

• Language: Go 1.24
• MCP SDK: github.com/modelcontextprotocol/go-sdk v1.2.0
• Transport: Dual-mode
  • stdio (standard input/output) for local Claude Desktop
  • HTTP streaming (streamable HTTP) for cloud deployment
• Caching: In-memory (1 hour TTL)
• HTTP Client: Native Go net/http
• Container: Multi-stage Docker build (~15MB final image)

📡 Data Source

• API: https://developers.events/all-cfps.json
• Community-driven, updated regularly
• Currently ~2,785 total CFPs, ~305 open
• Cached for 1 hour to reduce API load

🔒 Security

• No external dependencies beyond Go standard library and MCP SDK
• HTTPS-only API calls
• No data stored persistently
• Runs in user space (no elevated privileges needed)
• Statically compiled binary

🐛 Troubleshooting

Binary won't execute (macOS)

macOS may quarantine downloaded binaries. Remove the quarantine attribute:

xattr -d com.apple.quarantine mcp-server

Permission denied (Linux/macOS)

Make the binary executable:

chmod +x mcp-server

Claude Desktop doesn't see server

• Verify you're using the full absolute path in the config
• Restart Claude Desktop after config changes
• Check Claude Desktop logs:
  • macOS: ~/Library/Logs/Claude/
  • Windows: %APPDATA%\Claude\logs\

Server seems slow on first request

The first request fetches and caches data from developers.events API. Subsequent requests will be instant (served from 1-hour cache).
