# 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](https://docs.cloudzero.com/reference/introduction) and the [Model Context Protocol](https://modelcontextprotocol.io/introduction) MCP. ```mermaid graph LR %%{init: {'theme':'neutral'}}%% %% Define nodes A[MCP Host] B[Local MCP Server] C[CloudZero API] D[(Cloud Costs Data)] %% Define connections A -->|JSON-RPC 2.0| B B -->|HTTP/JSON| C C <--> D subgraph CloudZero_SaaS C D end subgraph Background_process B end subgraph Claude_Desktop A end subgraph Local_Machine Claude_Desktop Background_process end %% Define styles classDef client padding:10px classDef server padding:10px classDef api padding:10px classDef db padding:10px %% Apply styles class A client class B server class C api class D db ``` 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](https://spec.modelcontextprotocol.io/specification/2024-11-05/basic/lifecycle/#capability-negotiation), 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](https://claude.ai/download): Install [uv](https://docs.astral.sh/uv/) Setup the project dependencies: ```bash uv init uv sync ``` Generate your [CloudZero API key](https://app.cloudzero.com/organization/api-keys). Edit `.env` with: ```text CLOUDZERO_API_KEY=YOUR_SECRET_KEY ``` ## Install To install the MCP server into Claude Desktop: ```bash 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`. ```json "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](https://modelcontextprotocol.io/quickstart/user) for more info. ## Debug For debugging, you can run the MCP development server with an interactive GUI to inspect: ```bash uv run mcp dev server.py ``` This is useful for troubleshooting bugs in your code without having to continuously restart Claude Desktop.
