How to Use the Biconomy (Account Abstraction) MCP in Cursor

Q: How do I configure Biconomy (Account Abstraction) in my Cursor workspace?

Create a .cursor/mcp.json file in your project root and add the Biconomy MCP server configuration. Cursor will automatically detect the server and make the tools available in Agent mode.

Q: Can I use Biconomy (Account Abstraction) inside Cursor during an active debugging session?

Yes, the Cursor agent can call the MCP tools like getexplorerstatus to check your transaction state while you debug. This helps you identify if a transaction failed due to gas or execution errors.

Q: What happens if a Biconomy (Account Abstraction) quote expires in Cursor?

If the quote expires, the agent uses the getquote tool to fetch a fresh payload. This ensures your transaction executes with valid parameters.

Generate code and execute Biconomy smart account transactions directly from Cursor using live blockchain data.

Fetch real-time Biconomy quotes in Cursor Agent mode

The `get_quote` tool pulls live transaction pricing and routing data directly into your Cursor editing session. When writing smart contract execution scripts, your AI agent calls this tool to populate your code with real gas estimates instead of placeholder values. This lets you build and test your integration with actual network parameters. You avoid the typical cycle of writing code, running it in a terminal, and finding out your gas parameters are wrong.

Execute supertransactions with this MCP Server

The `execute_supertx` tool sends your signed transaction payloads to Biconomy chain relayers directly from the Cursor terminal or chat. Once you generate the signatures in your local test suite, Cursor passes the complete payload to this tool to trigger the execution. This integrates the entire transaction lifecycle into your coding workspace. You can write, sign, and broadcast transactions without leaving your editor.

Track Biconomy execution state inside Cursor

The `get_explorer_status` tool queries the status of your broadcasted supertransactions from within Cursor. Your agent checks the Biconomy explorer to verify if the smart account transaction successfully executed on-chain. You see the execution status and block details printed directly in your sidebar. This speeds up debugging because you can immediately trace execution failures alongside your code.

Setup guide

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

Common questions about Biconomy (Account Abstraction) MCP in Cursor

Create a `.cursor/mcp.json` file in your project root and add the Biconomy MCP server configuration. Cursor will automatically detect the server and make the tools available in Agent mode.

No, Cursor does not sign anything. You must sign the payload locally, and then pass that signed payload to the `execute_supertx` tool to execute the transaction.

Yes, the Cursor agent can call the MCP tools like `get_explorer_status` to check your transaction state while you debug. This helps you identify if a transaction failed due to gas or execution errors.

If the quote expires, the agent uses the `get_quote` tool to fetch a fresh payload. This ensures your transaction executes with valid parameters.

The server only accesses transaction quote payloads, signatures, and transaction hashes. Vinkius executes these MCP requests in ephemeral V8 containers, ensuring your transaction payloads are never stored or logged.
