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

Q: How does Windsurf use the Biconomy (Account Abstraction) MCP Server to chain transactions?

Cascade calls getquote to fetch the payload, writes a local script to sign it, and then passes the signed data to executesupertx. This entire flow runs autonomously without you copy-pasting hex strings.

Q: Can Windsurf handle transaction failures when using this MCP Server?

Yes, Cascade reads the error logs returned by executesupertx or getexplorerstatus. If a transaction reverts due to low gas, Cascade adjusts the quote parameters and retries the execution.

Q: How do I add this MCP Server to my Windsurf environment?

Open your mcpconfig.json file and add the server configuration under the mcpServers key. Once saved, Cascade immediately detects the three Biconomy tools and makes them available for your prompts.

Execute and track multi-chain Biconomy (Account Abstraction) supertransactions directly through Windsurf's Cascade agent.

Get Biconomy transaction quotes directly in Windsurf

The `get_quote` tool fetches gas-optimized Supertransaction quotes directly inside your Windsurf IDE. Cascade uses these raw quote payloads to prepare multi-chain transactions, letting you bypass manual JSON-RPC construction entirely. You just tell Cascade what token swap or bridge you want to trigger. It calls the tool, inspects the returned fees, and formats the exact payload needed for the next step of your deployment.

Execute Supertransactions via Windsurf Cascade

The `execute_supertx` tool signs and submits multi-chain transactions once Cascade adds the required user signatures to the payload. Windsurf coordinates this step by writing the local signing scripts, prompting you for local execution, and sending the final signed payload to the Biconomy bundlers. Because Cascade chains commands, it doesn't stop after generating the payload. It automatically writes the signing logic in your workspace, executes it, and passes the signatures right back to the tool.

Track execution status inside this MCP Server

The `get_explorer_status` tool monitors your Biconomy smart account transactions directly from the Windsurf editor. Cascade polls this tool after execution to confirm the transaction lands on-chain, keeping your workspace state in sync. Instead of jumping to a block explorer, you watch the transaction state update in your terminal panel. Cascade reads the status and updates your local smart contract deployment logs automatically.

Setup guide

Set up Biconomy (Account Abstraction) 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
