Frequently asked questions
Can I estimate gas for a specific EVM transaction before sending it?
Yes! Use the estimate_evm_gas tool by providing the chain, sender, recipient, and amount. It will return the estimated gas limit and price for that specific interaction.
How do I monitor a wallet for new incoming transactions automatically?
You can use the create_subscription tool to set up a webhook. This allows you to receive real-time notifications whenever a transaction occurs on the specified address and chain.
Can I check balances for multiple token types at once?
Yes, the get_wallet_portfolio tool allows you to specify token types like 'native', 'fungible' (ERC-20), and 'nft' to get a comprehensive view of an address's holdings.
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.
