"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


`

🔧 Advanced Configuration

$3

`json
{
"mcpServers": {
"spring-docs": {
"command": "npx",
"args": ["@enokdev/springdocs-mcp@latest"],
"env": {
"NODE_OPTIONS": "--max-old-space-size=4096",
"REQUEST_TIMEOUT": "15000",
"MAX_RETRIES": "3"
}
}
}
}
`

$3

`json
{
"mcpServers": {
"spring-docs": {
"command": "npx",
"args": ["@enokdev/springdocs-mcp@latest"],
"env": {
"HTTP_PROXY": "http://proxy.company.com:8080",
"HTTPS_PROXY": "http://proxy.company.com:8080"
}
}
}
}

🧪 Testing & Development

$3

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

$3

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

$3

`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

$3

#### "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})

$3


`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"
