> **🚀 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
```json
{
"mcpServers": {
"spring-docs": {
"command": "npx",
"args": ["@enokdev/springdocs-mcp@latest"],
"description": "Spring Documentation MCP Server with 12 powerful tools"
}
}
}
```
#### Gemini CLI
```yaml
mcp_servers:
spring-docs:
command: "npx"
args: ["@enokdev/springdocs-mcp@latest"]
description: "Spring Documentation Server"
```
#### VS Code MCP Extension
```json
{
"mcp.servers": {
"spring-docs": {
"command": "npx",
"args": ["@enokdev/springdocs-mcp@latest"]
}
}
}
```
#### Any MCP Client (NPX)
```bash
npx @enokdev/springdocs-mcp@latest
```
#### Global Installation (All Clients)
```bash
npm install -g @enokdev/springdocs-mcp
# Then use: springdocs-mcp
```
#### Docker (Coming Soon - Docker MCP Catalog)
```bash
# 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
```bash
echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/list", "params": {}}' | npx @enokdev/springdocs-mcp@latest
```
### Development Setup
```bash
git clone https://github.com/tky0065/springdocs-mcp.git
cd springdocs-mcp
npm install
npm run build
npm test
```
### Load Testing
```bash
# 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"
```bash
# 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"
```bash
# 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`:
```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
```bash
#!/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"
```
