Storacha MCP Storage Server
A Model Context Protocol (MCP) server implementation for Storacha hot storage, allowing AI applications to store and retrieve files through a standardized interface. It enables trustless, decentralized data exchange using IPFS and CIDs, ensuring data sovereignty, verifiability, and seamless integration with agent frameworks & AI systems.

Quick Installation Guide
Get started with the Storacha MCP Storage Server in just a few simple steps.
**Clone the Repository**
```bash
git clone https://github.com/storacha/mcp-storage-server.git && cd mcp-storage-server
```
**Install Dependencies**
```bash
pnpm install
```
**Generate Keys & Delegation**
- **Install the CLI**
```bash
npm install -g @web3-storage/w3cli
```
- **Login to Storacha**
```bash
w3 login
```
_Output:_
```
? How do you want to login?
Via Email
Via GitHub
```
_Select **Via GitHub** and authenticate with your GitHub account._
- **Create a Space**
```bash
w3 space create <your_space_name>
```
_Replace `<your_space_name>` with a name for your new Space_. :warning: _Make sure you save the recovery key, so you can access your space from another device if needed._
- **Create a Private Key**
```bash
w3 key create
```
_Output:_
```txt
AgentId: did:key:z6MkhMZRW2aoJ6BQwkpMSJu68Jgqkz1FTpr1p69cpnN43YWG
PrivateKey: LMgCYLkvOc8Sm0mOL4cWFLxsWP0ZPEYrLxcQqsV93/s5RLje0BKx05muAse1Hkvh+sxUW38OcHtpiN1zxfpTJ4ht4jxV0=
```
- **Set the Agent ID & Create Delegation**
```bash
w3 delegation create <agent_id> \
--can 'store/add' \
--can 'filecoin/offer' \
--can 'upload/add' \
--can 'space/blob/add' \
--can 'space/index/add' --base64
```
_Replace <agent_id> with the AgentId from the previous step. It grants the Agent the permission to store files into the recently created space_.
**Configure the MCP Client**
Next, configure your MCP client (such as Cursor) to use this server. Most MCP clients store the configuration as JSON in the following format:
```jsonc
{
"mcpServers": {
"storacha-storage-server": {
"command": "node",
"args": ["./dist/index.js"],
"env": {
// The server also supports `sse` mode, the default is `stdio`.
"MCP_TRANSPORT_MODE": "stdio",
// The Storacha Agent private key that is authorized to store data into the Space.
"PRIVATE_KEY": "<agent_private_key>",
// The base64 encoded delegation that proves the Agent is allowed to store data. If not set, MUST be provided for each upload request.
"DELEGATION": "<base64_delegation>",
},
"shell": true,
"cwd": "./",
},
},
}
```
_Replace `<agent_private_key>` with the PrivateKey you created in step 3. Then, replace the `<base64_delegation>` with the delegation you created in step 3._
_:warning: There are several ways to configure MCP clients, please read the [integrations.md](https://github.com/storacha/mcp-storage-server/blob/main/docs/integrations.md) guide for more information._
Tools
The Storacha MCP Storage Server provides the following tools for AI systems to interact with a decentralized storage network.
Storage Operations
upload
Upload a file to the Storacha Network. The file must be provided as a base64 encoded string with a filename that includes the extension for MIME type detection.
retrieve
Retrieve a file from the Storacha Network. Supported filepath formats: `CID/filename`, `/ipfs/CID/filename`, or `ipfs://CID/filename`.
identity
Returns the `DIDKey` of the Storacha Agent loaded from the private key storage configuration.
See the [integrations.md](https://github.com/storacha/mcp-storage-server/blob/main/docs/integrations.md) guide for detailed code examples and different integration patterns (SDK, Docker, etc).
