HPE GreenLake reporting MCP Server

reporting MCP Server

HPE GreenLake reporting MCP Server provides read-only access to the HPE GreenLake reporting APIs through the Model Context Protocol.

Overview

This MCP server enables AI assistants and development tools to interact with HPE GreenLake reporting programmatically. It follows the standardized MCP server architecture with shared authentication components and HTTP client adapters.

Key Features

• Read-only API access to reporting endpoints
• Shared authentication using OAuth2 with automatic token management
• Standardized architecture following HPE GreenLake MCP patterns
• Type-safe implementations using Pydantic models
• Comprehensive logging and error handling

Quick Start

Prerequisites

• Python 3.10 or higher
• uv package manager
• HPE GreenLake workspace with API credentials

Installation

From PyPI (recommended):

pip install greenlake-reporting-mcp

After installation, run the server with:

python -m greenlake_reporting_mcp

Configuration

Set the following environment variables:

Variable	Required	Description	Example
GREENLAKE_API_BASE_URL	Yes	Base URL for GreenLake APIs	https://global.api.greenlake.hpe.com
GREENLAKE_CLIENT_ID	Yes	OAuth2 client ID	your-client-id
GREENLAKE_CLIENT_SECRET	Yes	OAuth2 client secret	your-client-secret
GREENLAKE_WORKSPACE_ID	Yes	Workspace identifier (token issuer auto-generated from this)	your-workspace-id
MCP_TOOL_MODE	No	Tool operation mode (see Tool Modes section)	static (default) or dynamic
GREENLAKE_LOG_LEVEL	No	Logging level for stderr output	ERROR (default), WARNING, INFO, DEBUG
GREENLAKE_FILE_LOGGING	No	Enable file logging to disk	false (default) or true

Logging

This MCP server uses loguru for structured logging with strict MCP protocol compliance.

Log Destinations

stderr (Default):

• All diagnostic logs go to stderr (MCP protocol requirement)
• Controlled by GREENLAKE_LOG_LEVEL (default: ERROR)
• stdout is reserved exclusively for JSON-RPC messages

File logging (Optional):

• Enable with GREENLAKE_FILE_LOGGING=true
• Logs written to: ~/.hpe/mcp-logs/reporting/reporting-mcp.log
• Features:
  • Automatic rotation at 10 MB
  • 7-day retention policy
  • Always logs at DEBUG level for comprehensive diagnostics
  • Includes detailed context (module, function, line number)

Configuration Examples

Production (minimal logging):

export GREENLAKE_LOG_LEVEL=ERROR
# File logging disabled by default

Development (verbose logging):

export GREENLAKE_LOG_LEVEL=DEBUG
export GREENLAKE_FILE_LOGGING=true

Debugging specific issues:

export GREENLAKE_LOG_LEVEL=INFO
export GREENLAKE_FILE_LOGGING=true
# Check logs at: ~/.hpe/mcp-logs/reporting/

Log Filtering

The server automatically filters noisy third-party library logs:

• httpx, httpcore, urllib3, asyncio are limited to WARNING level and above
• This preserves important error messages (connection failures, timeouts, SSL issues)
• While suppressing verbose DEBUG/INFO output (connection pooling, retries)

Tool Modes

This MCP server supports two different tool operation modes that can be switched at runtime:

Static Mode (Default)

• Individual tools: Each API endpoint becomes a dedicated MCP tool
• Type-safe: Explicit tool definitions with compile-time validation
• Discoverable: Tools appear individually in MCP client interfaces
• Best for: Smaller APIs with focused functionality

Dynamic Mode

• Meta-tools: 3 generic tools that can handle any API endpoint
• Runtime discovery: Endpoints are discovered and validated at runtime
• Memory efficient: Lower overhead for large APIs
• Best for: Large APIs with many endpoints

Tools available in dynamic mode:

• list_endpoints - Discover available API endpoints with optional filtering
• get_endpoint_schema - Get detailed schema information for specific endpoints
• invoke_dynamic_tool - Execute API calls with runtime parameter validation

Switching Modes

Configure the MCP_TOOL_MODE environment variable in your MCP client configuration:

{
  "servers": {
    "reporting": {
      "env": {
        "MCP_TOOL_MODE": "static"  // or "dynamic"
      }
    }
  }
}

• static - Individual tools per endpoint (default)
• dynamic - 3 generic meta-tools for all endpoints

Available Tools

This server provides the following MCP tools:

getreportingstatuses

• Description: This API is designed to fetch the status of all reports for a specific workspace. Only reports belonging to the workspace ID and username are returned. This API supports pagination, allowing you to use offset and limit parameters.

• Method: GET /reporting/v1/statuses

• Parameters:

  • filter (str, required):
    Example: type eq "REPORT"

Filter Syntax: Use OData-style filters with the field names shown in the examples above. String values must be enclosed in double quotes.

• sort (str, optional):
  The order in which to return the resources in the collection.The value of the sort query parameter is a comma separated list of sort expressions. Each sort expression is a property name optionally followed by a direction indicator asc (ascending) or desc (descending).The first sort expression in the list defines the primary sort order, the second defines the secondary sort order, and so on. If a direction indicator is omitted the default direction is ascending. Examples: - name,createdAt desc Order resources ascending by name and then by descending by createdAt - name asc Order ascending by name
• limit (int, optional):
  The maximum number of reports to return.

Example: 50

• offset (int, optional):
  Zero-based resource offset to start the response from.

Example: 20

getreportingstatusbyid

• Description: Retrieve the status of a specific report by passing the report status ID.

• Method: GET /reporting/v1/statuses/{id}

• Parameters:

  • id (str, required):
    The report status identifier.

Example: 3fa85f64-5717-4562-b3fc-2c963f66afa6

Typical Use Cases

This MCP server enables AI assistants to answer natural language questions about your HPE GreenLake reporting resources. Here are some example queries you can try:

reporting Queries:

• "List all reporting resources"
• "Show me details for specific reporting items"
• "Find reporting by specific criteria"
• "Get status of reporting resources"
• "Show me recent reporting changes"

These are just examples - you can ask questions in your own words, and the AI assistant will use the appropriate MCP tools to retrieve the information from HPE GreenLake.

API Coverage

This MCP server implements read-only access to the following reporting API endpoints:

• GET /reporting/v1/statuses - This API is designed to fetch the status of all reports for a specific workspace. Only reports belonging to the workspace ID and username are returned. This API supports pagination, allowing you to use offset and limit parameters.

• GET /reporting/v1/statuses/{id} - Retrieve the status of a specific report by passing the report status ID.

Adding New Tools

1. Create a new tool file in tools/implementations/
2. Inherit from BaseTool and implement required methods
3. Add the tool to tools/registry.py
4. Write tests in tests/
5. Update this README

Testing

The test suite reads credentials from environment variables. Export the following variables before running integration tests:

export GREENLAKE_CLIENT_ID=your-client-id
export GREENLAKE_CLIENT_SECRET=your-client-secret
export GREENLAKE_WORKSPACE_ID=your-workspace-id
export GREENLAKE_API_BASE_URL=https://global.api.greenlake.hpe.com

Run the full test suite (unit + integration when credentials are present):

make test

Run unit-only checks:

make test-unit

Integration smoke tests require the variables above plus any tool arguments (MCP_TEST_REPORTING_<PARAM_NAME>):

make test-integration

The generated suite provides:

• Unit tests for tools, server wiring, and models
• Shared fixtures and helpers for deterministic behaviour
• Integration tests guarded by environment variable checks
• Coverage reporting within the unit suite

Troubleshooting

Common Issues

Server won't start:

• Verify environment variables are set

• Check that the package is installed: pip show greenlake-reporting-mcp

• Review log output for specific errors

Authentication failures:

• Verify client credentials are valid
• Check workspace ID is correct
• Ensure network connectivity to GreenLake

Tool execution errors:

• Check API endpoint availability
• Verify request parameters
• Review error logs for details
