SysInfo Java MCP Server

A Model Context Protocol (MCP) server implementation in Java that provides system information tools for AI assistants. This server exposes process management capabilities through a Spring Boot application with Spring AI integration.

Features

  • Process Listing: List all running processes with pagination support
  • Process Inspection: Detailed inspection of specific processes by PID
  • MCP Server: Compatible with MCP clients and AI assistants

Prerequisites

  • Java 21 or higher
  • Gradle 8.x (or use the included Gradle wrapper)

Installation

  1. Clone the repository:

    git clone https://github.com/asahasrabuddhe/mcp-sysinfo-java.git
cd sysinfo-java

  2. Build the project:

    ./gradlew build

Usage

Running the Server

Start the MCP server:

./gradlew bootRun

The server will start and be ready to accept MCP tool requests.

Available Tools

1. List Processes

Lists all running processes with pagination support.

2. Inspect Process

Inspect a specific process by its Process ID (PID).

Configuration

The application can be configured through src/main/resources/application.properties:

spring.application.name=sysinfo-java
spring.main.bannerMode=off
logging.level.root=OFF
logging.pattern.console=%msg%n

Building Distribution

./gradlew build

The built JAR will be available in build/libs/.

Dependencies

  • Spring Boot 3.5.3: Core framework
  • Spring AI MCP Server 1.0.0: MCP server implementation
  • Jackson 2.17.1: JSON processing
  • JUnit 5: Testing framework

Technical Details

MCP Integration

This server implements the Model Context Protocol (MCP) using Spring AI's MCP server capabilities. Tools are exposed through the @Tool annotation and automatically registered with the MCP server.

Process Management

The server uses Java's ProcessHandle API to interact with system processes, providing:

  • Safe process enumeration
  • Process metadata extraction
  • Cross-platform compatibility

Security Considerations

  • The server only provides read-only access to process information
  • No process control capabilities (start/stop/kill) are exposed
  • Process information is limited to what's available through standard Java APIs
