How to Use the Filebase (Web3 Storage) MCP in Cursor

Q: Can Cursor automate pinning using Filebase (Web3 Storage)?

Yes, the Cursor agent can automate pinning by calling psaaddpin during your coding or build session. It ensures your newly generated build artifacts are persistently stored on IPFS.

Q: Does the Filebase (Web3 Storage) server support local IPFS RPC commands in Cursor?

Yes, the server exposes raw RPC tools like rpcadd and rpccat to Cursor. This lets your agent read and write IPFS blocks directly from your workspace.

Q: How do I configure this server for a single Cursor project?

Create a .cursor/mcp.json file in your project root and add the Filebase server config. Cursor will automatically load these tools for that specific workspace.

Pin IPFS assets and resolve IPNS names directly inside your Cursor workspace.

Inject live IPFS metadata into your Cursor code

This MCP Server links Cursor directly to your Filebase buckets to pull real-time storage metrics into your active editor. When writing decentralized apps, Cursor uses `platform_get_usage` to fetch exact storage bytes and injects them directly into your configuration files. You get actual production data instead of placeholder values. Cursor queries `platform_get_bucket_usage` to write precise, live-tested code without leaving your workspace.

Automate IPFS pinning workflows during Cursor agent runs

This toolset lets the Cursor agent pin build artifacts to IPFS automatically as you write your deployment scripts. The agent executes `psa_add_pin` or `rpc_pin_add` to lock down your build directories right after compiling. No manual pinning steps required. Cursor monitors the deployment and uses `psa_get_pin` to verify the persistence status before finishing its run.

Resolve and publish IPNS names while editing code

The server gives Cursor the ability to manage your mutable Web3 pointers directly from the editor's chat panel. Your agent can run `rpc_name_resolve` to check an active IPNS hash or `platform_update_name` to point a key to your latest build. You don't need to jump to an external CLI to update your site. Cursor handles the keys using `rpc_key_list` and updates the pointers as soon as your code changes.

Setup guide

Set up Filebase (Web3 Storage) MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Filebase (Web3 Storage) MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Filebase (Web3 Storage) transactions." If the MCP tools are loaded correctly, Cursor will call the Filebase (Web3 Storage) tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "filebase-web3-storage-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
