A JVM monitoring MCP server implementation based on Arthas, providing a simple and easy-to-use Python interface for monitoring and analyzing Java processes.

• Automatic download and management of Arthas tools
• Support for local and remote Java process monitoring
• Java process list querying
• Real-time JVM thread information
• JVM memory usage monitoring
• Thread stack trace information
• Class loading information querying
• Support for class and method decompilation
• Method call monitoring
• Dynamic log level adjustment
• AI-driven JVM performance analysis

• Python 3.10+
• Java Runtime Environment (JRE) 8+
• Network connection (for downloading Arthas)
• SSH access to target server (if using remote mode)

## linux shell
curl -LsSf https://astral.sh/uv/install.sh | sh
## or install using pip
pip install uv
## or install using pipx (if you have pipx installed)
pipx install uv 
## windows powershell
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

git clone https://github.com/xzq-xu/jvm-mcp-server.git
cd jvm-mcp-server

# Create virtual environment
uv venv
# Sync project dependencies
uv sync

Create a .env file and add the following configurations:

# Linux/Mac
ARTHAS_SSH_HOST=user@remote-host
ARTHAS_SSH_PORT=22  # Optional, default is 22
ARTHAS_SSH_PASSWORD=your-password  # If using password authentication

# Windows PowerShell
$env:ARTHAS_SSH_HOST="user@remote-host"
$env:ARTHAS_SSH_PORT="22"  # Optional, default is 22
$env:ARTHAS_SSH_PASSWORD="your-password"  # If using password authentication

1. Start the server using uv:

# Start in local mode
uv run jvm-mcp-server

# Start with environment file (if remote connection is configured)
uv run --env-file .env jvm-mcp-server

# Start in a specific directory (if needed)
uv --directory /path/to/project run --env-file .env jvm-mcp-server

2. Use in Python code:

from jvm_mcp_server import JvmMcpServer

server = JvmMcpServer()
server.run()

3. Using MCP tools:

Using configuration file:

{
    "mcpServers": {
      "jvm-mcp-server": {
        "command": "uv",
        "args": [
          "--directory",
          "/path/to/jvm-mcp-server",
          "run",
          "--env-file",
          "/path/to/jvm-mcp-server/.env",
          "jvm-mcp-server"
        ]
      }
    }
}

Without using configuration file, it will read system environment variables, if not present it will monitor local threads:

{
    "mcpServers": {
      "jvm-mcp-server": {
        "command": "uv",
        "args": [
          "--directory",
          "/path/to/jvm-mcp-server",
          "run",
          "jvm-mcp-server"
        ]
      }
    }
}

Available Tools List

1. Ensure Java is installed in the runtime environment
2. Arthas tool will be automatically downloaded on first run (arthas will be downloaded to home directory, can be downloaded in advance and named as arthas-boot.jar)
3. Requires access permissions to target Java process
4. Remote mode requires SSH access and appropriate user permissions
5. Recommended for use in development environment, production use should be carefully evaluated
