เปิดJava SDK for building custom Model Context Protocol (MCP) servers quickly, with runnable MySQL and Redis server examples.
MCP.so listings: MySQL MCP Server for Java · Redis MCP Server for Java
Full walkthrough: 5-Minute Quick Start.
Core SDK:
<dependency>
<groupId>io.github.6000fish</groupId>
<artifactId>mcp-sdk</artifactId>
<version>0.1.1</version>
</dependency>
Spring Boot starter:
<dependency>
<groupId>io.github.6000fish</groupId>
<artifactId>mcp-spring-boot-starter</artifactId>
<version>0.1.1</version>
</dependency>
Build the no-database quick-start server:
mvn package -pl mcp-examples/quick-start -am -DskipTests
Add the runnable jar to your MCP Agent configuration:
{
"mcpServers": {
"quick-start": {
"type": "stdio",
"command": "java",
"args": [
"-jar",
"/absolute/path/to/mcp-java/mcp-examples/quick-start/target/quick-start-0.1.1.jar"
]
}
}
}
Restart the Agent and ask:
Use the quick-start MCP server to greet Alice and get the current time.
The demo exposes greet, current_time, calculate, text_transform, and resource server://info.
For a copyable annotation-based template:
mvn package -pl mcp-examples/custom-server-template -am -DskipTests
Configure the generated jar:
{
"mcpServers": {
"custom-template": {
"type": "stdio",
"command": "java",
"args": [
"-jar",
"/absolute/path/to/mcp-java/mcp-examples/custom-server-template/target/custom-server-template-0.1.1.jar"
]
}
}
}
Then edit CustomMcpServer.java and add your own @McpTool, @McpResource, or @McpPrompt methods.
Minimal SDK API example:
McpServer server = DefaultMcpServer.builder()
.name("my-server")
.version("1.0.0")
.build();
server.tool("greet", "Greet someone", arguments -> {
String name = (String) arguments.getOrDefault("name", "World");
return ToolCallResult.success("Hello, " + name + "!");
});
server.start(new StdioTransport());
Annotation example:
@McpServer(name = "my-server", version = "1.0.0")
public class MyServer {
@McpTool(name = "hello", description = "Say hello")
public String hello(@Param(name = "name") String name) {
return "Hello, " + name + "!";
}
}
Build the currently published ready-to-use server modules:
mvn package -pl mcp-server-collection/mcp-server-mysql -am -DskipTests
mvn package -pl mcp-server-collection/mcp-server-redis -am -DskipTests
MySQL server config:
{
"mcpServers": {
"mysql": {
"type": "stdio",
"command": "java",
"args": [
"-jar",
"/absolute/path/to/mcp-java/mcp-server-collection/mcp-server-mysql/target/mcp-server-mysql-0.1.1.jar"
],
"env": {
"MYSQL_HOST": "localhost",
"MYSQL_PORT": "3306",
"MYSQL_DATABASE": "mcp_demo",
"MYSQL_USERNAME": "my_user",
"MYSQL_PASSWORD": "your_password"
}
}
}
}
Redis server config:
{
"mcpServers": {
"redis": {
"type": "stdio",
"command": "java",
"args": [
"-jar",
"/absolute/path/to/mcp-java/mcp-server-collection/mcp-server-redis/target/mcp-server-redis-0.1.1.jar"
],
"env": {
"REDIS_HOST": "localhost",
"REDIS_PORT": "6379",
"REDIS_PASSWORD": ""
}
}
}
}
Before connecting real data, read the Security Guide. Keep credentials in local Agent configuration or environment variables only.
User documentation:
Maintainer documentation:
The stdio servers are designed for mainstream MCP clients and Agents:
tools/list, tools/call, and client _meta fields.Compatibility safeguards include required inputSchema on tools, tolerant request parsing for client extension fields such as _meta, omitted null fields in stdio responses, and logging to stderr so stdout stays reserved for MCP JSON-RPC messages.
