Apache Pinot + NVIDIA Agent Intelligence Toolkit: Complete MCP Integration
Apache Pinot is a MCP server that MCP server for Apache Pinot real-time analytics database with SQL query capabilities and metadata access.
When integrated with NVIDIA Agent Intelligence Toolkit, you can:
- List and inspect Apache Pinot tables
- View and analyze table segments
- Retrieve and analyze table schemas
This guide provides step-by-step instructions to set up Apache Pinot in NVIDIA Agent Intelligence Toolkit, including configuration, examples, and troubleshooting.
What You'll Achieve
After completing this setup:
- Apache Pinot will be fully integrated and operational
- You can use Apache Pinot tools directly in NVIDIA Agent Intelligence Toolkit
- All Apache Pinot capabilities will be available for your workflows
- Access to 5 different tools
Prerequisites
Before starting, ensure you have:
- Apache Pinot broker hostname
- Apache Pinot broker port
- NVIDIA Agent Intelligence Toolkit installed and configured
- Compatible operating system (Python Package (pip), Docker Container, Framework Integration)
Installation
Step 1: Install Apache Pinot
Configuration
Step 2: Configure NVIDIA Agent Intelligence Toolkit
- Open NVIDIA Agent Intelligence Toolkit settings
- Navigate to MCP server configuration
- Add Apache Pinot server with appropriate settings
- Save and restart if needed
Examples
Once configured, you can use Apache Pinot in NVIDIA Agent Intelligence Toolkit:
List All Tables
Get overview of available Pinot tables
Ask NVIDIA Agent Intelligence Toolkit: "Show me all the tables available in the Pinot cluster"
Expected Result: List of table names with basic metadata and schema information
Execute Analytics Query
Run SQL query for real-time analytics
Ask NVIDIA Agent Intelligence Toolkit: "SELECT COUNT(*) FROM events WHERE timestamp > now() - 3600000"
Expected Result: Query results showing event count for last hour
Analyze Table Structure
Get detailed schema information for a table
Ask NVIDIA Agent Intelligence Toolkit: "Show me the schema and structure of the user_events table"
Expected Result: Table schema with column names, types, and index information
Generate Data Visualization
Create histogram plots from query results
Ask NVIDIA Agent Intelligence Toolkit: "Create a histogram showing user activity distribution by hour"
Expected Result: Histogram visualization with data aggregated by time buckets
Testing Your Setup
- Launch NVIDIA Agent Intelligence Toolkit
- Verify Apache Pinot is available in the tools list
- Test basic Apache Pinot functionality
Troubleshooting
Common Issues
uv Command Not Found
Symptoms: Command not found error, uv: command not found
Cause: uv package manager not installed
Solution:
- Install uv using: curl -LsSf https://astral.sh/uv/install.sh | sh
- Restart terminal or source shell configuration
- Verify installation with: uv --version
Pinot Connection Failed
Symptoms: Connection refused, Broker unreachable, Network timeout
Cause: Invalid Pinot broker configuration or cluster not running
Solution:
- Verify PINOT_BROKER_HOST and PINOT_BROKER_PORT in .env file
- Check Pinot cluster is running and accessible
- Test connection: telnet <broker_host> <broker_port>
- Ensure firewall allows connections to Pinot broker
Environment Variables Not Loaded
Symptoms: Config missing errors, Default values being used
Cause: .env file not found or incorrectly formatted
Solution:
- Create .env file in repository root directory
- Copy from .env.example and modify values
- Ensure no spaces around = in variable assignments
- Restart MCP server after configuration changes
Claude Desktop Not Recognizing Server
Symptoms: Server not appearing, Connection errors in Claude
Cause: Incorrect claude_desktop_config.json configuration
Solution:
- Verify path to uv binary in command field
- Ensure correct path to mcp-pinot repository
- Restart Claude Desktop after configuration changes
- Check Claude Desktop logs for error messages
MCP Server Connection Failed
Symptoms: Connection refused errors, Timeout connecting to MCP server, URL not responding
Cause: MCP server not running or incorrect URL configuration
Solution:
- Verify MCP server is running and accessible
- Check URL in configuration matches server endpoint
- Ensure network/firewall allows connection to server port
- Test connection with curl or browser before agent integration
Tool Schema Validation Errors
Symptoms: Invalid input format errors, Schema mismatch warnings, Type validation failures
Cause: Input data does not match MCP tool schema
Solution:
- Use CLI to inspect tool schema: aiq info mcp --url <url> --tool <name>
- Validate input data matches expected types and required fields
- Check JSON schema definitions in MCP server documentation
- Convert inputs to proper format (dict, JSON string, or schema instance)
Framework Integration Issues
Symptoms: Import errors, Framework not found, Incompatible versions
Cause: Missing or incompatible framework dependencies
Solution:
- Ensure target framework (LangChain, LlamaIndex, etc.) is installed
- Check version compatibility between AIQ toolkit and framework
- Install framework-specific dependencies as needed
- Refer to documentation for framework-specific configuration
Performance Bottlenecks
Symptoms: Slow agent responses, High token usage, Workflow timeouts
Cause: Inefficient tool usage or workflow design
Solution:
- Enable observability to identify bottlenecks
- Use profiling features to analyze tool and agent performance
- Review token tracking metrics to optimize LLM calls
- Consider hyperparameter tuning for agent optimization
OpenTelemetry Integration Errors
Symptoms: Observability data not appearing, Telemetry export failures, Missing metrics
Cause: OpenTelemetry not properly configured
Solution:
- Verify OpenTelemetry collector is running
- Check observability configuration in AIQ settings
- Ensure proper instrumentation of agent workflows
- Review OpenTelemetry export settings and endpoints
Apache Pinot not appearing in NVIDIA Agent Intelligence Toolkit
Symptoms: Server not listed, Tools not available
Cause: Configuration or installation issue
Solution:
- Verify configuration syntax
- Check Apache Pinot installation
- Restart NVIDIA Agent Intelligence Toolkit
- Check logs for error messages
