What is Cloud Storage MCP Server?
A Model Context Protocol (MCP) server for Google Cloud Storage that enables interactions with Google Cloud Storage buckets and files. It is intended for developers using Claude Desktop or other MCP-compatible clients to manage GCS resources via natural language commands.
How to use Cloud Storage MCP Server?
Install dependencies with npm install, build with npm run build, then configure Claude Desktop by adding a JSON entry to claude_desktop_config.json that points to the built index.js and sets the GOOGLE_CLOUD_PROJECTS environment variable. Place a corresponding .json credential file for each project in the keys folder.

Frequently asked questions
What are the prerequisites to use the server?
You need Node.js, npm, at least one Google Cloud project, and a service account with appropriate Cloud Storage permissions (e.g., Storage Admin). Credential files in JSON format must be placed in the `keys` folder.
How do I configure the server?
Set the `GOOGLE_CLOUD_PROJECTS` environment variable to a comma-separated list of project IDs (the first is the default). The server expects a credential file named `<project-id>.json` inside the `keys` directory for each project.
What tools does the server provide?
The server exposes seven tools: `listBuckets`, `getBucket`, `listFiles`, `getFile`, `uploadFile`, `downloadFile`, and `deleteFile`.
Where are credentials stored?
Credentials are stored locally in the `keys` folder as JSON files named after the Google Cloud project ID (e.g., `keys/my-project-id.json`). Ensure the service account has the necessary IAM permissions on the targeted Cloud Storage resources.
