Cloud Storage MCP Server

A Model Context Protocol (MCP) server for Google Cloud Storage that enables interactions with Google Cloud Storage buckets and files.

Features

• List Cloud Storage buckets in a project
• Get details of a specific bucket
• List files in a bucket
• Get details of a specific file
• Upload files to a bucket
• Download files from a bucket
• Delete files from a bucket

Setup

1. Install dependencies:

npm install

2. Build the project:

npm run build

3. Configure Claude Desktop:

Add the following to your `claude_desktop_config.json`:

"cloudstorage-mcp": {
     "command": "node",
     "args": [
       "/path/to/cloudstorage-mcp/build/index.js"
     ],
     "env": {
       "GOOGLE_CLOUD_PROJECTS": "project-id1,project-id2"
     }
   }

Replace the path in args with the actual path to index.js.

Define a comma-separated list of project IDs in GOOGLE_CLOUD_PROJECTS.

Example: `google-project-id1,google-project-id2`

The first listed project is the default.

The application expects to find .json credential file(s) in the keys folder for each project.

Example: keys/google-project-id1.json

Ensure the relevant cloud service account has appropriate permission to interact with Cloud Storage, e.g. `Storage Admin` or lesser permission(s).
