Perplexity

Autonomous permaweb data retrieval

Cascade doesn't just read data; it understands your codebase context to pull specific blocks or transaction IDs. It uses `get_block_by_hash` or `get_block_by_height` to verify chain state without you leaving the editor. When you need to audit historical data, the agent triggers `get_transaction_data` to pull raw bytes into your workspace. It handles the parsing so you can focus on the logic.

Verify Arweave storage costs with Windsurf

Stop guessing your migration budget. Cascade calls `get_storage_price` to calculate exactly how many Winstons you need for your latest deployment. This MCP Server provides the math in real-time. You get the cost breakdown before you commit to a single transaction.

Execution of complex transactions

Cascade can chain `submit_transaction` with local file operations to push data to the permaweb. It monitors the status using `get_transaction_status` until the write is confirmed. You provide the intent, and the agent handles the multi-step verification process. It's a closed-loop workflow for your decentralized assets.

Setup guide

Set up Arweave MCP in Windsurf

Prerequisites

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

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the Arweave MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my Arweave payment history." If connected, Cascade will call the Arweave tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about Arweave MCP in Windsurf

You add the server to your configuration file, and Cascade discovers the tools instantly. It connects to the network, letting you query data or check balances without writing manual API calls.

Yes, Cascade can execute `submit_transaction` if you provide the necessary keys. It keeps the process contained within your IDE session.

The server only touches the public transaction metadata and data blocks you explicitly request. It doesn't store your private keys or sensitive project files on the permaweb.

It defaults to the public gateway, but you can point it to a custom node. This ensures your queries stay fast and reliable.

Open the MCP panel in the IDE and look for the server status. If it's green, run `get_network_info` to see the current state of the chain.
