How to Use the Fireblocks MCP in Cursor

Q: How do I install the Fireblocks MCP Server in Cursor?

Add the server configuration to your .cursor/mcp.json file in your project root. Once saved, Cursor automatically spins up the server in the background. Your agent can then access the tools in chat.

Q: Can my Cursor agent check my Fireblocks staking positions?

Yes, your agent can call liststakingpositions to check active yields. It pulls the live data directly into your editor so you can analyze your treasury balance in real time.

Q: How does the Fireblocks integration in Cursor handle webhook setup?

Your agent uses createwebhook to establish notification endpoints during development. It can also run listwebhooknotifications to debug incoming payloads without leaving the editor.

Write smart contracts and build automated crypto treasury workflows using live Fireblocks data right inside Cursor.

Automate vault creation in Cursor

The `create_vault_account` tool allows your Cursor agent to generate new secure storage accounts programmatically while you write your backend code. You don't need to copy-paste IDs from the browser. The agent uses `list_vault_accounts` to fetch active vaults and injects their real IDs directly into your codebase. It saves you from hardcoding static values and prevents configuration drift during local testing.

Manage whitelisted contracts from the editor

The `add_contract` tool lets your agent whitelist external smart contracts directly from your workspace. This MCP Server makes it easy to register new protocols without context switching. Your agent calls `list_contracts` to verify which addresses are safe to interact with. It then updates your local configuration files with the exact contract details returned by `get_contract_asset`.

Fetch real-time gas estimates in Cursor

The `estimate_fee` tool gives your agent instant access to transaction cost calculations directly inside your editor, functioning as a local MCP utility. This prevents deployment failures caused by underfunded wallets or incorrect gas limits. The agent uses `estimate_network_fee` to write dynamic gas estimation logic directly into your test suites. You get realistic transaction simulations before deploying your code to mainnet.

Setup guide
