Perplexity

Build web3 apps with live balances

Writing a dApp frontend usually means mocking wallet states for hours. Agent mode lets Cursor pull actual mainnet numbers via `get_wallet_balance` while you type. The editor injects real wei values into your test cases automatically. Handling token math is notoriously tricky in JavaScript. Calling `get_token_balances` feeds the exact ERC-20 decimals and amounts into your workspace. Your agent writes parsing logic based on live responses instead of static JSON files.

Fetch transaction receipts in Cursor

Debugging failed smart contract calls requires digging through block explorers. You skip that step entirely by running `get_transaction_receipt` directly from the command palette chat. The AI reads the gas used and revert reasons right inside your IDE. Knowing the current chain state prevents stale data errors. Executing `get_latest_block_number` gives your script the exact target block to listen for. This MCP Server keeps your development environment perfectly synced with mainnet.

Audit NFT contracts instantly

Verifying token ownership usually requires writing temporary fetch scripts. Firing `get_owned_nfts` dumps the entire collection data into your context window. You see exactly which tokens an address holds without leaving the file you are editing. API reliability dictates how fast you ship. Triggering `check_api_status` confirms the node connection works before you start coding complex logic. Every MCP Server operation here exists to keep your hands on the keyboard.

Setup guide

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

.cursor/mcp.json

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

Common questions about Alchemy MCP in Cursor

Create an mcp.json file in your project root directory. Paste the server command and arguments under the mcpServers array. Turn on Agent mode in the chat panel to start querying chain data.

Yes, the AI reads real wallet balances and transaction receipts. It uses those exact values to generate assertion statements in your test files.

You can connect to a remote endpoint by adding the URL instead of a local command. The editor routes your web3 queries through that secure connection.

Blockchains return values in their lowest denomination. You need to tell the agent to format the output using standard web3 utility libraries.

The server only processes the specific transaction hashes and wallet strings you ask it to check. Vinkius routes these requests through a zero-trust architecture. Your proprietary source files never leave the IDE.
