Cloudzero Model Context Protocol Server

by burkestar
Verified

local-only server

The server can only run on the client’s local machine because it depends on local resources.

Integrations

  • Supports environment variable configuration through .env files for storing API keys and other sensitive configuration.

  • Supports rendering of Mermaid diagrams to visualize architecture and data flows between components.

Cloudzero Model Context Protocol (MCP) server

Talk to your cloud cost data in Cloudzero from a Large Language Model (LLM).

Ask questions about your cost data such as plotting a month over month difference:

How it works

Uses CloudZero v2 API and the Model Context Protocol MCP.

Once the MCP server is configured in Claude Desktop, it will be launched as a background process at startup. Claude Desktop as the MCP Host will send an initiatize request to the MCP Server. The server responds with its capabilities, which includes prompts and tools for tool calling.

The server implements several tools specific to CloudZero:

  • get_costs to get billing data from start_date to end_date
  • get_dimensions for billing dimensions
  • list_budgets to list budgets
  • list_insights to list insights

The MCP protocol uses JSON-RPC 2.0 for requests and responses.

Setup

Install Claude Desktop:

Install uv

Setup the project dependencies:

uv init uv sync

Generate your CloudZero API key.

Edit .env with:

CLOUDZERO_API_KEY=YOUR_SECRET_KEY

Install

To install the MCP server into Claude Desktop:

uv run mcp install server.py

Edit your claude_desktop_config.json to set the proper path to the uv command and update your USERNAME as below.

This config file can be located in Claude Desktop under 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" ] }

Restart Claude Desktop. When the Desktop starts, it will launch the server process in the background. You may see errors, and can drill into the logs to see what the problem is.

If no errors, try asking "what tools are available for cloud billing" to see it listed.

See Claude Desktop MCP documentation for more info.

Debug

For debugging, you can run the MCP development server with an interactive GUI to inspect:

uv run mcp dev server.py

This is useful for troubleshooting bugs in your code without having to continuously restart Claude Desktop.
