## Features
* Job management (submit, stop, monitor)
* System monitoring and information retrieval
* REST API interaction with SeaTunnel services
* Built-in logging and monitoring tools
* Dynamic connection configuration
* Comprehensive job information and statistics
## Installation
```bash
# Clone repository
git clone <repository_url>
cd seatunnel-mcp
# Create virtual environment and install
python -m venv .venv
source .venv/bin/activate # On Windows: .venv\Scripts\activate
pip install -e .
```
## Requirements
* Python ≥ 3.12
* Running SeaTunnel instance
* Node.js (for testing with MCP Inspector)
## Usage
### Environment Variables
```
SEATUNNEL_API_URL=http://localhost:8090 # Default SeaTunnel REST API URL
SEATUNNEL_API_KEY=your_api_key # Optional: Default SeaTunnel API key
```
### Dynamic Connection Configuration
The server provides tools to view and update connection settings at runtime:
* `get-connection-settings`: View current connection URL and API key status
* `update-connection-settings`: Update URL and/or API key to connect to a different SeaTunnel instance
Example usage through MCP:
```json
// Get current settings
{
"name": "get-connection-settings"
}
// Update connection settings
{
"name": "update-connection-settings",
"arguments": {
"url": "http://new-host:8090",
"api_key": "new-api-key"
}
}
```
### Job Management
The server provides tools to submit and manage SeaTunnel jobs:
* `submit-job`: Submit a new job with job configuration
* `submit-jobs`: Submit multiple jobs in batch
* `stop-job`: Stop a running job
* `get-job-info`: Get detailed information about a specific job
* `get-running-jobs`: List all currently running jobs
* `get-finished-jobs`: List all finished jobs by state (FINISHED, CANCELED, FAILED, etc.)
### Running the Server
```bash
python -m src.seatunnel_mcp
```
### Usage with Claude Desktop
To use this with Claude Desktop, add the following to your `claude_desktop_config.json`:
```json
{
"mcpServers": {
"seatunnel": {
"command": "python",
"args": ["-m", "src.seatunnel_mcp"],
"cwd": "Project root directory"
}
}
}
```
### Testing with MCP Inspector
```bash
npx @modelcontextprotocol/inspector python -m src.seatunnel_mcp
```
## Available Tools
### Connection Management
* `get-connection-settings`: View current SeaTunnel connection URL and API key status
* `update-connection-settings`: Update URL and/or API key to connect to a different instance
### Job Management
* `submit-job`: Submit a new job with configuration in HOCON format
* `submit-job/upload`: submit job source upload configuration file
* `submit-jobs`: Submit multiple jobs in batch, directly passing user input as request body
* `stop-job`: Stop a running job with optional savepoint
* `get-job-info`: Get detailed information about a specific job
* `get-running-jobs`: List all currently running jobs
* `get-running-job`: Get details about a specific running job
* `get-finished-jobs`: List all finished jobs by state
### System Monitoring
