How to Use the Fireblocks MCP in Windsurf

Q: Can Windsurf handle complex Fireblocks transaction flows?

Yes. Since your agent chains tools, it can run estimatefee followed by createtransaction in one go. It handles the sequence logic so you don't have to.

Q: Does Windsurf show Fireblocks compliance errors?

The agent reports exactly what the API returns. If validatetravelrule fails, it halts the process and shows you the specific error message in the chat.

Let your Windsurf agent move digital assets, manage vaults, and execute transactions without you leaving your IDE.

Full vault management in Windsurf

Your agent handles account lifecycle tasks directly. It uses `create_vault_account` to spin up new storage and `create_vault_account_asset` to provision specific asset addresses. Windsurf chains these calls to ensure your treasury structure stays organized. You'll see the agent verify balances via `get_vault_account_asset` before it commits to any outbound move.

Automated transaction execution

Cascade takes your high-level instructions and turns them into secure `create_transaction` calls. It checks the network health first using `estimate_network_fee` to avoid stuck operations. If a transaction needs extra scrutiny, the agent automatically runs `validate_travel_rule`. This keeps your compliance posture clean without manual oversight.

Real-time asset monitoring

The agent watches your portfolio by polling `list_transactions` and `list_vault_accounts`. It maps your entire footprint across every supported blockchain. When new data hits, it refreshes your local state using `refresh_nfts` or `list_assets`. You get a clear view of your holdings without switching windows.

Common questions about Fireblocks MCP in Windsurf

Keep your API credentials in your environment variables, never in plain text files. Your MCP server picks these up at runtime so your agent can sign requests securely.

Yes. Since your agent chains tools, it can run `estimate_fee` followed by `create_transaction` in one go. It handles the sequence logic so you don't have to.

The agent reports exactly what the API returns. If `validate_travel_rule` fails, it halts the process and shows you the specific error message in the chat.

It doesn't. Your agent fetches the data live from the platform using `list_transactions` every time you ask for a report.

No. The agent only interacts with the Fireblocks API primitives. It never sees or stores your actual private keys; it just tells the platform what to sign.
