🚀 Enhanced v1.2.8: 12 powerful tools with Spring AI support, intelligent caching, advanced tutorials, and comprehensive Spring ecosystem access

🌐 Universal MCP Compatibility: Works with Claude Code, Gemini CLI, VS Code, JetBrains IDEs, and all MCP-compatible clients!

🎯 Quick Start

🔌 Universal MCP Compatibility

This server works with ALL MCP-compatible clients:

Claude Desktop/Code

{
  "mcpServers": {
    "spring-docs": {
      "command": "npx",
      "args": ["@enokdev/springdocs-mcp@latest"],
      "description": "Spring Documentation MCP Server with 12 powerful tools"
    }
  }
}

Gemini CLI

mcp_servers:
  spring-docs:
    command: "npx"
    args: ["@enokdev/springdocs-mcp@latest"]
    description: "Spring Documentation Server"

VS Code MCP Extension

{
  "mcp.servers": {
    "spring-docs": {
      "command": "npx",
      "args": ["@enokdev/springdocs-mcp@latest"]
    }
  }
}

Any MCP Client (NPX)

npx @enokdev/springdocs-mcp@latest

Global Installation (All Clients)

npm install -g @enokdev/springdocs-mcp
# Then use: springdocs-mcp

Docker (Coming Soon - Docker MCP Catalog)

# Via Docker MCP CLI (when available in catalog)
docker mcp add springdocs-mcp

# Via Docker directly
docker pull mcp/springdocs-mcp:latest
echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/list"}' | \
  docker run -i mcp/springdocs-mcp:latest

Benefits of Docker distribution:

• Enhanced security with cryptographic signatures and SBOMs
• Isolated execution environment
• Reduced token usage in Docker Desktop
• Automatic security updates

Config file locations:

• Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) / %APPDATA%\Claude\claude_desktop_config.json (Windows)
• Claude Code: ~/.claude-code/mcp-config.json
• VS Code: ~/.vscode/mcp-settings.json
• JetBrains IDEs: .jetbrains/mcp-config.json

🧪 Testing & Development

Quick Test

echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/list", "params": {}}' | npx @enokdev/springdocs-mcp@latest

Development Setup

git clone https://github.com/tky0065/springdocs-mcp.git
cd springdocs-mcp
npm install
npm run build
npm test

Load Testing

# Test multiple tools quickly
for tool in "search_spring_docs" "search_spring_projects" "search_spring_ecosystem"; do
  echo "Testing $tool..."
  echo "{\"jsonrpc\": \"2.0\", \"id\": 1, \"method\": \"tools/call\", \"params\": {\"name\": \"$tool\", \"arguments\": {\"query\": \"test\", \"limit\": 2}}}" | npx @enokdev/springdocs-mcp@latest > /dev/null
done

🆘 Troubleshooting

Common Issues & Solutions

"Server failed to start"

# Check Node.js version (requires 18+)
node --version

# Update to latest
npm update -g @enokdev/springdocs-mcp

# Clear cache
npm cache clean --force

"Tools not responding"

# Test connectivity
curl -I https://spring.io

# Check Claude Desktop config syntax
cat ~/Library/Application\ Support/Claude/claude_desktop_config.json | jq .

"Slow performance"

• Enable caching (automatic in v1.2.3+)
• Use specific queries instead of broad searches
• Increase memory: NODE_OPTIONS="--max-old-space-size=4096"

"Port 8080 already in use" (Spring Boot error)

Solution: Change port in application.properties:

server.port=8081

"Failed to configure DataSource"

Solutions:

1. Add database dependency to pom.xml
2. Configure datasource in application.properties
3. Exclude auto-configuration: @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})

Health Check Script

#!/bin/bash
echo "🔍 Testing Spring MCP Server..."

# Test server startup
timeout 10s echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/list", "params": {}}' | npx @enokdev/springdocs-mcp@latest > /dev/null
echo $? -eq 0 && echo "✅ Server: OK" || echo "❌ Server: FAILED"

# Test network
curl -s --max-time 5 https://spring.io > /dev/null
echo $? -eq 0 && echo "✅ Network: OK" || echo "❌ Network: FAILED"
