IPFS Storacha Network

Publish Docker Publish NPM npm version smithery badge

A Node.js server implementing the Model Context Protocol (MCP) for interacting with the storacha.network platform via the w3 command-line interface (@web3-storage/w3cli).

This server empowers language models 🤖 and other MCP clients to manage storacha.network spaces, upload/download data, manage delegations, and perform various other tasks by seamlessly wrapping w3 commands.

✨ Features

• Wraps the w3 CLI for native integration with storacha.network.
• Provides MCP tools covering a wide range of w3 functionality:
  • 🔑 Authentication & Agent: w3_login, w3_reset, w3_account_ls (for checking authorization)
  • 📦 Space Management: w3_space_ls, w3_space_use, w3_space_info, w3_space_add, w3_space_provision (Note: w3_space_create must be run manually due to interactive prompts)
  • 💾 Data Management: w3_up, w3_ls, w3_rm
  • 🔗 Sharing: w3_open (generates w3s.link URL)
  • 🤝 Delegations & Proofs: w3_delegation_create, w3_delegation_ls, w3_delegation_revoke, w3_proof_add, w3_proof_ls
  • 🔐 Keys & Tokens: w3_key_create, w3_bridge_generate_tokens
  • ⚙️ Advanced Storage (w3 can ...): Blob, CAR, Upload, Index, Access Claim, Filecoin Info management
  • 💳 Account & Billing: w3_plan_get, w3_coupon_create, w3_usage_report

🛠️ Prerequisites

• Node.js: Version 22.0.0 or higher (node -v).
• w3 CLI: The server executes w3 commands directly. Ensure @web3-storage/w3cli is installed globally and configured:

  npm install -g @web3-storage/w3cli
  w3 login <[email protected]>
  # Follow email verification steps
  

• Environment Variable: The w3_login tool requires the W3_LOGIN_EMAIL environment variable to be set to the same email used for w3 login.

🏗️ Project Structure

The codebase is organized as follows:

src/
├── index.ts          # Main server entry point, MCP setup, request routing
├── schemas.ts        # Zod schemas defining input arguments for each tool
├── tool_handlers.ts  # Implementation logic for each MCP tool
├── utils.ts          # Helper functions (e.g., running w3 commands, parsing JSON)
└── utils/
    └── logger.ts     # Basic logger configuration

🚀 Usage with MCP Clients

This server can be used with any MCP-compatible client. You need to configure your client to connect to this server.

Example: NPX (Recommended for simple local use)

This assumes npm and the prerequisites are met.

{
  "mcpServers": {
    "ipfs": {
      "command": "npx",
      "args": ["-y", "mcp-ipfs"],
      "env": {
        "W3_LOGIN_EMAIL": "[email protected]"
      }
    }
  }
}

Example: Docker

Build the image first (see Build section) or use the pre-built image alexbakers/mcp-ipfs.

{
  "mcpServers": {
    "mcp-ipfs": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-v",
        "/path/to/your/project:/path/to/your/project",
        "-e",
        "W3_LOGIN_EMAIL",
        "alexbakers/mcp-ipfs"
      ],
      "env": {
        "W3_LOGIN_EMAIL": "[email protected]"
      }
    }
  }
}

📝 Note on Paths:

Several w3 commands require absolute filesystem paths (e.g., w3_up, w3_delegation_create --output, w3_proof_add, w3_can_blob_add, w3_can_store_add).

• NPX: Provide absolute paths from your host machine.
• Docker: Provide absolute paths inside the container. If interacting with files from your host (e.g., uploading), you must mount the relevant host directory into the container using the -v flag (e.g., -v /Users/me/project:/Users/me/project) and then use the container path (e.g., /Users/me/project/my_file.txt) in the tool arguments.

📦 Build

Clone the repository and install dependencies:

git clone https://github.com/alexbakers/mcp-ipfs.git
cd mcp-ipfs
npm install

Build the TypeScript code:

npm run build

You can then run the server directly:

# Ensure W3_LOGIN_EMAIL is set in your environment
export W3_LOGIN_EMAIL="[email protected]"
node dist/index.js

Or publish it (if you have the rights):

npm publish

🐳 Docker Build

Build the Docker image:

# Build locally (replace with your username/repo and desired tag)
docker build -t alexbakers/mcp-ipfs .
