## Example Usage
Once configured, you can ask Claude questions like:
### Basic Information
- "What version of SSB am I running?"
- "List all my SQL streams"
- "What tables are available for querying?"
- "What connectors are available?"
- "List all Kafka topics"
- "How is the cluster health?"
*Claude can show all available tables in the SSB environment, including both built-in and custom tables.*
### Query Execution & Data Access
- "Execute this query: SELECT * FROM NVDA"
- "Create a job with sample all messages: SELECT * FROM NVDA"
- "Show me the status of job 1234"
*Claude can list all running SSB jobs, showing their status, creation time, and details.*
- "Get sample data from job 1234"
- "List all jobs with their sample information"
- "Show me the latest data from the ReadNVDA job"
### Job Management & Control
- "Stop job 1234"
- "Restart job 1234 with sample all messages"
- "Restart job 1234 with custom sampling (500ms interval)"
- "Configure sampling for job 1234 to sample all messages"
*Claude can create new SSB jobs by executing SQL queries, with full job management capabilities.*
### Stream Management
- "Create a new stream called 'sales_analysis' with this SQL: SELECT * FROM sales WHERE amount > 1000"
- "Show me the details of the 'user_events' stream"
- "What's the status of my 'sales_stream'?"
### Kafka Table Management
- "Create a local Kafka table called 'user_events' from topic 'user-events'"
- "Register a Kafka table in the Flink catalog to make it queryable"
- "Create a local Kafka table with JSON format"
*Claude can create new virtual tables connected to Kafka topics, with proper schema and connector configuration.*
- "Validate if 'local-kafka' is a valid connector type"
- "Create a virtual table for real-time data streaming"
### Advanced Job Management
- "Show me the event history for job 1234"
- "Get the detailed state of job 1234"
- "Copy job 1234 to create a new job"
- "Clone the data source for table 'user_events'"

- "Create a materialized view endpoint for job 1234"
### Materialized Views
- "Get materialized view endpoints for job 1234"
- "Create a materialized view endpoint for job 1234"
**⚠️ Important Limitation**: Materialized Views (MVs) must be created through the SSB UI interface. The MCP server can retrieve data from existing materialized views but cannot create new ones programmatically. To create a materialized view:
1. Navigate to your job in the SSB UI
2. Go to the Materialized Views section
3. Configure and create the MV through the UI
4. Use the MCP server to query the created MV data
## ⚠️ Known Limitations
### Job Restart Capabilities
**Limited Restart Functionality**: The SSB API provides limited job restart capabilities:
**✅ What Works:**
- `stop_job(job_id, savepoint=True)` - Stops jobs with savepoints
- `restart_job_with_sampling(job_id, sql_query, ...)` - Creates new jobs with updated SQL
- `PUT /jobs/{id}` - Updates job configuration
**❌ What Doesn't Work:**
- Direct job restart via dedicated restart endpoints
- `start_stream(stream_name)` - Stream start endpoints return 404
- `stop_stream(stream_name)` - Stream stop endpoints return 404
- `execute_job(job_id, sql_query)` - Database connection issues
**Recommended Restart Strategy:**
```python
# For restarting a job with new SQL
def restart_siem_job(job_id, new_sql):
try:
# Stop the existing job
client.stop_job(job_id, savepoint=True)
# Create new job with updated SQL
result = client.restart_job_with_sampling(job_id, new_sql)
return result
except Exception as e:
print(f"Restart failed: {e}")
```
### Virtual Tables and System Catalogs
**Limited Table Discovery**: The SSB environment has limited traditional table support:
**✅ What's Available:**
- **System Catalogs**: 2 catalogs (`default_catalog`, `ssb`)
- **Functions**: 206 built-in functions for data processing
- **Materialized Views**: Accessible via MVE API (not SQL)
**❌ What's Not Available:**
- Traditional database tables (SHOW TABLES returns empty)
- Standard information_schema queries
- Direct SQL access to materialized views
- System tables for metadata discovery
**Data Access Methods:**
- **Direct SQL**: Limited to functions and basic queries
- **MVE API**: For materialized view data (requires Basic Auth)
- **Job Execution**: For creating and managing data streams
### Authentication and Configuration
**Configuration Loading**: The MCP server now supports both JSON configuration files and environment variables:
**✅ JSON Configuration**: Update `config/cloud_ssb_config.json` and restart the MCP server
**✅ Environment Variables**: Set environment variables (takes precedence over JSON)
**✅ MVE API Credentials**: Configure `mve_username` and `mve_password` in JSON or environment variables
**⚠️ Important**: For Cloudera AI Agent Studio, use environment variables:
```bash
export KNOX_GATEWAY_URL="your_gateway_url"
export KNOX_TOKEN="your_jwt_token"
export SSB_API_BASE="your_api_base"
export MVE_USERNAME="your_mve_username"
export MVE_PASSWORD="your_mve_password"
```
**Token Expiration**: JWT tokens expire and require manual refresh. The MCP server doesn't automatically refresh tokens.
### Cloud Environment Limitations
**Endpoint Availability**: Some endpoints may not be available in cloud environments:
**❌ Cloud Limitations:**
- `list_projects()` - May return "Request method 'GET' not supported"
- `get_heartbeat()` - May return empty responses
- `create_stream()` and `execute_query()` - May timeout with 500 errors
- `SHOW JOBS` - Not supported in cloud environment
**✅ Workarounds:**
- Use `list_streams()` instead of `list_projects()`
- Skip heartbeat checks in cloud environments
- Handle timeouts gracefully with retry logic
- Use job management tools instead of SHOW commands
### Materialized View Engine (MVE) API
**Separate Authentication**: MVE API requires different authentication than the main SSB API:
**Authentication Requirements:**
- **SSB API**: Bearer token authentication
- **MVE API**: Basic authentication (username:password)
- **Credentials**: Must be provided separately for MVE access
**Access Pattern:**
```python
# MVE API access requires Basic Auth
credentials = 'username:password'
encoded_credentials = base64.b64encode(credentials.encode()).decode()
headers = {'Authorization': f'Basic {encoded_credentials}'}
```
### Monitoring & Diagnostics
- "Check the system heartbeat and health"
- "Show me the diagnostic counters"
- "Analyze this SQL query for performance: SELECT * FROM NVDA WHERE close > 100"
- "What's the current system performance?"
### Enhanced Table Management
- "Show me detailed information about all tables"
- "Get the hierarchical table structure by catalog"
- "Validate this data source configuration"
- "Create a new table with full configuration"
- "Get detailed information about table 'user_events'"
*Claude can provide detailed information about specific tables, including their schema and configuration.*
### User & Project Management

- "Create a new UDF for data transformation"
- "Update UDF 'my_function' configuration"
- "Get UDF artifacts and dependencies"
### Sample Data Examples
The MCP server can retrieve real-time streaming data samples with different sampling modes:
*Claude can retrieve real-time sample data from running jobs, showing actual streaming data.*
**Periodic Sampling (default):**
```json
{
"records": [
{
"___open": "185.0919",
"___high": "185.1200",
"___low": "184.9400",
"___close": "184.9700",
"___volume": "61884",
"eventTimestamp": "2025-10-08T18:34:10.915Z"
}
],
"job_status": "RUNNING",
"end_of_samples": false,
"message": "Retrieved 1 sample records"
}
```
**Sample All Messages Mode:**
```json
{
"sampling_mode": "sample_all_messages",
"sample_interval": 0,
"sample_count": 10000,
"window_size": 10000,
"message": "Job created with comprehensive sampling enabled"
}
```
### SQL Query Features
- **Automatic Semicolon Handling**: All SQL queries are automatically terminated with semicolons
- **Flexible Sampling**: Choose between periodic sampling or sample all messages
- **Job Control**: Start, stop, and restart jobs with different configurations
- **Real-time Data**: Access streaming data samples from running jobs
## Advanced Features
### Sample All Messages
For comprehensive data sampling, use the `sample_all_messages=True` option:
```python
# Create job with sample all messages
execute_query_with_sampling("SELECT * FROM NVDA", sample_all_messages=True)
# Restart job with sample all messages
restart_job_with_sampling(1234, "SELECT * FROM NVDA", sample_all_messages=True)
```
**Configuration:**
- `sample_interval: 0` (sample immediately)
- `sample_count: 10000` (high count to capture all messages)
- `window_size: 10000` (large window for comprehensive sampling)
### Custom Sampling Configuration
Fine-tune sampling behavior for your specific needs:
```python
# Custom sampling with 500ms interval
execute_query_with_sampling("SELECT * FROM NVDA",
sample_interval=500,
sample_count=500,
window_size=500)
# Configure existing job sampling
configure_sampling("sample_id",
sample_interval=200,
sample_count=1000,
window_size=1000)
```
### Job Management
Complete job lifecycle management:
```python
# Stop job with savepoint
stop_job(1234, savepoint=True)
# Restart job with new SQL
execute_job(1234, "SELECT * FROM NEW_TABLE")
# Restart with sampling options
restart_job_with_sampling(1234, "SELECT * FROM NVDA",
sample_interval=1000,
sample_all_messages=False)
```
### Kafka Table Creation
Create tables that are restricted to local-kafka connector only:
```python
# Step 1: Create data source (creates configuration)
create_kafka_table("user_events", "user-events") # Uses local-kafka by default
# Step 2: Register table in Flink catalog (makes it queryable)
register_kafka_table("user_events", "user-events") # Creates ssb_user_events in ssb.ssb_default (falls back to default_catalog.ssb_default)
# Advanced: Custom schema registration
custom_schema = [
{"name": "id", "type": "STRING"},
{"name": "name", "type": "STRING"},
{"name": "timestamp", "type": "TIMESTAMP"}
]
register_kafka_table("custom_table", "custom-topic", custom_schema) # Creates ssb_custom_table
# Without ssb_ prefix
register_kafka_table("raw_data", "raw-topic", use_ssb_prefix=False) # Creates raw_data (no prefix)
# Custom catalog and database
register_kafka_table("custom_table", "custom-topic", catalog="default_catalog", database="default_database")
# Local Kafka with custom settings
create_kafka_table("local_data", "local-topic", "local-kafka", "localhost:9092", "json", "earliest-offset")
register_kafka_table("local_data", "local-topic") # Creates ssb_local_data
# Validate connector types
validate_kafka_connector("local-kafka") # Returns validation details
validate_kafka_connector("kafka") # Returns error - only local-kafka allowed
```
**Two-Step Process**: Creating a Kafka table requires two steps:
1. **Create Data Source**: Use `create_kafka_table()` to create the data source configuration
2. **Register in Catalog**: Use `register_kafka_table()` to make the table queryable
**Automatic Registration**: The `register_kafka_table()` function:
- Uses DDL to register the table in the Flink catalog (default: `ssb.ssb_default`, falls back to `default_catalog.ssb_default`)
- Configurable catalog and database parameters for flexible namespace control
- Automatic catalog fallback when requested catalog is not available
- Creates tables in the same database as existing tables like NVDA by default
- Automatically adds `ssb_` prefix to table names (configurable)
- Automatically creates a schema based on the topic data
- Verifies the table is available for querying by checking the correct database context
- Returns confirmation of successful registration with full table name, catalog, and database info
**Naming Conventions**:
- **Default**: Tables get `ssb_` prefix automatically (e.g., `user_events` → `ssb_user_events`)
- **Override**: Use `use_ssb_prefix=False` to disable prefix
- **Existing**: Tables already starting with `ssb_` are not modified
**Namespace Configuration**:
- **Default**: Tables created in `ssb.ssb_default` namespace (falls back to `default_catalog.ssb_default` if `ssb` catalog unavailable)
- **Custom Catalog**: Use `catalog` parameter to specify different catalog
- **Custom Database**: Use `database` parameter to specify different database
- **Automatic Fallback**: System automatically falls back to `default_catalog` if requested catalog is not available
- **Full Control**: Both catalog and database are configurable for maximum flexibility
**Verification**:
- Use `SHOW TABLES;` to confirm tables are available for querying
- Tables are created in `default_catalog.ssb_default` namespace (same as NVDA)
- Use full namespace (`default_catalog.ssb_default.TABLE_NAME`) or switch database context with `USE default_catalog.ssb_default;`
- All virtual Kafka tables are co-located with existing tables for easy querying
**Supported Connector:**
- `local-kafka` - Local Kafka connector (only option for virtual tables)
**Supported Formats:**
- `json` - JSON format (default)
- `csv` - CSV format
- `avro` - Apache Avro format
- Custom format strings

## Write Operations
By default, the server runs in read-only mode for CDP deployments and write-enabled for standalone deployments. To change this:
1. Set `SSB_READONLY=false` (enable writes) or `SSB_READONLY=true` (read-only)
2. Restart the MCP server
Write operations include:
- Creating, updating, and deleting streams
- Executing SQL queries that create jobs
- Managing job lifecycle (start, stop, restart)
- Configuring sampling parameters
- Job control and management
- Creating Kafka-only tables (enforced validation)

## Troubleshooting
### Common Issues
1. **"Unauthorized" errors**: Check your authentication credentials
- For direct SSB: Verify `SSB_USER` and `SSB_PASSWORD`
- For Knox: Verify `KNOX_TOKEN` or `KNOX_USER`/`KNOX_PASSWORD`
2. **"Connection refused" errors**: Ensure SSB services are running
- Check `docker-compose ps` for service status
- Verify port mappings in docker-compose.yml
3. **"No sample data available"**: Jobs may need time to produce data
- Check job status with `get_job_status(job_id)`
- Verify the job is running and has sample configuration
- Try using `sample_all_messages=True` for comprehensive sampling
4. **Job restart failures**: If job restart fails
- Use `restart_job_with_sampling()` instead of `execute_job()`
- Check if the job is in a state that allows restarting
- Create a new job if restart is not possible
- Note: `start_stream()` and `stop_stream()` methods don't work (404 errors)
5. **SSL certificate errors**: For Knox deployments
- Set `KNOX_VERIFY_SSL=false` for self-signed certificates
- Or provide proper CA bundle with `KNOX_CA_BUNDLE`
6. **Kafka table creation errors**: If table creation fails
- Verify that only local-kafka connector is used (enforced)
- Check that the Kafka topic exists and is accessible
- Ensure bootstrap servers are correctly configured
- Use `validate_kafka_connector()` to check connector validity
7. **Virtual tables not available for querying**: After creating Kafka tables
- **Important**: Creating a data source doesn't automatically make it available for querying
- Data sources need to be manually registered in the Flink catalog through the SSB UI
- Use `SHOW TABLES;` to see which tables are actually available for querying
- Only tables that appear in `SHOW TABLES;` can be queried via SQL
8. **Configuration not updating**: After updating `config/cloud_ssb_config.json`
- **Important**: Environment variables take precedence over JSON configuration
- For JSON config: Update `config/cloud_ssb_config.json` and restart the MCP server
- For environment variables: `export KNOX_TOKEN="new_token"` and restart
- Check which method is being used by your deployment
9. **Materialized View access errors**: When accessing MVE API
- MVE API requires Basic authentication (username:password)
- SSB API uses Bearer token authentication
- Use different credentials for MVE API access
- Check that the job is running before accessing its MV
10. **Empty table lists**: When running `SHOW TABLES`
- SSB environment has limited traditional table support
- Use `list_streams()` to see available jobs
- Access materialized views via MVE API, not SQL
- Focus on job-based data processing rather than table queries
### Debug Mode
Enable debug logging by setting environment variable:
```bash
export MCP_LOG_LEVEL=DEBUG
```
## Security
- All sensitive data (passwords, tokens, secrets) is automatically redacted in responses
- Large collections are truncated to prevent overwhelming the LLM
- Read-only mode is enabled by default for CDP deployments to prevent accidental modifications
- Direct SSB authentication uses basic auth over HTTP (suitable for local development)
- SQL queries are automatically sanitized with proper semicolon termination
- Kafka table creation enforces local-kafka-only connector for data security
