CloudZero Model Context Protocol (MCP) Connector for LLM Interaction

Enable conversational access to your comprehensive CloudZero financial telemetry from within a Large Language Model (LLM) environment.

Pose complex inquiries regarding your cost structures, such as generating comparative visualizations of sequential monthly expenditure variances:

Operational Methodology

This integration relies upon the CloudZero v2 API documentation and adheres strictly to the Model Context Protocol (MCP) specification.

Following the proper configuration of the MCP service agent within the controlling client (e.g., Claude Desktop), it initiates as a background daemon upon system startup. The client, acting as the MCP Host, transmits an initialize handshake request to the server. The server replies by detailing its operational capabilities, which encompass definitions for contextual prompts and callable tools.

The agent implements a specialized toolkit specific to CloudZero operations:

• get_costs: Retrieves detailed accounting records spanning a specified start_date through an end_date.
• get_dimensions: Fetches available categorization vectors for financial breakdown.
• list_budgets: Enumerates all configured financial limitations.
• list_insights: Pulls automatically generated analytical observations.

The underlying MCP framework standardizes communication via JSON-RPC 2.0 messaging for all inter-process exchanges.

Deployment Prerequisites

Install the controlling client, Claude Desktop:

Install the project dependency manager, uv:

Configure project environment dependencies:

bash uv init uv sync

Procure your unique CloudZero API authentication token.

Populate the configuration file .env with credentials:

text CLOUDZERO_API_KEY=YOUR_SECRET_KEY

Installation Procedure

To integrate the MCP service agent into the controlling client environment:

bash uv run mcp install server.py

Modify your operational configuration file, claude_desktop_config.json, to specify the accurate filesystem path for the uv executable and substitute the placeholder USERNAME:

This configuration artifact is typically accessible via the Desktop client path: Settings > Developer > Edit Config.

"CloudZero": {
  "command": "/Users/USERNAME/.local/bin/uv",
  "args": [
    "run",
    "--with",
    "mcp[cli]",
    "mcp",
    "run",
    "/Users/USERNAME/workspace/open_source/cloudzero-mcp/server.py"
  ]
}

Initiate a restart of the controlling Desktop application. Upon initialization, the service agent process will commence execution in the background. Scrutinize the resultant logs for any initialization anomalies.

If the startup sequence completes without apparent faults, validate functionality by issuing a query such as, "Which data query instruments are accessible for cloud expenditure review?" to confirm tool registration.

Consult the Claude Desktop MCP documentation for supplementary details.

Diagnostic Routines

For debugging purposes, the development instance of the MCP server can be launched, providing an interactive graphical interface for inspecting runtime operations:

bash uv run mcp dev server.py

This isolated execution environment is highly beneficial for resolving code defects without requiring repeated restarts of the primary controlling client software.
