Why Cursor?
Cursor's Agent mode turns Biconomy (Account Abstraction) into an in-editor superpower. Ask Cursor to generate code using live data from Biconomy (Account Abstraction) and it fetches, processes, and writes. all in a single agentic loop. 3 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Frequently asked questions
How do I request a quote for a gasless (sponsored) transaction?
Use the get_quote tool and simply omit the feeToken parameter. Biconomy will analyze the flow and return a quote where the gas is sponsored.
What do I need to provide to the execute tool after getting a quote?
You must provide the full quotePayload to the execute_supertx tool. Ensure that the required signatures have been added to the payloadToSign fields within that object.
Can I check the status of a transaction that is currently processing?
Yes. Use the get_explorer_status tool with the supertxHash returned by the execution endpoint to track its real-time progress on the blockchain.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
