How to Use the Arweave MCP in Cursor

Q: Can I write Arweave integration code faster using Cursor?

Yes. Cursor uses tools like gettransaction to pull live data, allowing the AI to generate accurate parsing code on the fly.

Q: How does the Arweave MCP Server help with debugging in Cursor?

It lets you inspect blocks using getblockbyhash or getblockbyheight directly in your chat sidebar. You don't have to search block explorers manually.

Q: Can Cursor check my Arweave wallet balance?

Yes. The editor calls getwalletbalance with your public address to display your current funds in Winstons instantly.

Q: How do I submit transactions from the editor?

You use submittransaction to push payloads directly to the gateway. Your agent can build, format, and broadcast the transaction in one go.

Write code that interacts with the permaweb using live Arweave network data inside Cursor.

Generate code using live transaction data

Stop writing code against mock blockchain payloads that don't match reality. With this MCP Server, Cursor pulls live transaction records using `get_transaction` and `get_transaction_data` directly into your active editor. Your agent writes parsing logic using real, production-grade data from the permaweb. This eliminates integration bugs before you compile.

Estimate deployment costs using this MCP Server

Budgeting for permanent storage shouldn't require leaving your code editor. Your agent calls `get_storage_price` to calculate exactly how many Winstons your assets will cost to store forever. You can also track your treasury by querying `get_wallet_balance` to make sure your automated scripts have enough funding. It brings financial context directly to your development flow.

Query the permaweb with GraphQL in Cursor

Writing custom indexing code is tedious when you don't know the schema or tags. This tool lets Cursor run `query_graphql` to discover how other dApps structure their data on the network. It speeds up your development by showing you live examples of transaction tags and block structures. You build faster because your editor understands the live state of the blockchain.

Setup guide

Set up Arweave 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 Arweave 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 Arweave transactions." If the MCP tools are loaded correctly, Cursor will call the Arweave tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

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