How to Use the BlockCypher (Multi-chain Blockchain Developer API) MCP in Windsurf

Q: Can Cascade build and sign transactions using BlockCypher (Multi-chain Blockchain Developer API) on Windsurf?

Yes. Cascade uses newtransaction to generate the unsigned skeleton transaction. You sign it locally, and Cascade uses sendtransaction to broadcast it to the network.

Query and broadcast multi-chain transactions natively inside Windsurf using Cascade's autonomous chains.

Multi-Chain Data Retrieval via Windsurf

`get_blockchain` pulls the live state of Bitcoin or Ethereum directly into your Cascade panel without leaving your editor. Cascade reads this network context, decides which block height to inspect, and uses `get_block_by_height` or `get_block_by_hash` to grab transaction details instantly. You don't write boilerplate fetch requests. Cascade chains these tools to track down specific transactions with `get_transaction` and extracts the exact payload you need for your local debugging.

Automated Wallet and Testnet Funding

`generate_address` creates fresh keys and addresses for your test environments on demand using this MCP Server. When Cascade detects a low balance during local testing, it runs `fund_bcy_test_address` or `fund_beth_test_address` to secure testnet funds automatically. Your agent checks the wallet state using `get_address_balance` before running your test suite. This keeps your integration tests running smoothly without manual faucet visits.

Direct Smart Contract and Transaction Execution

`create_eth_contract` deploys your compiled smart contracts directly from your workspace. Cascade handles the deployment sequence, then runs `call_eth_contract_method` to verify your contract state in real-time. For standard transfers, Cascade builds the unsigned payload with `new_transaction` and pushes the signed hex to the network using `send_transaction`. This turns your editor into a fully functional web3 deployment terminal.

Setup guide

Set up BlockCypher (Multi-chain Blockchain Developer API) 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

Add the BlockCypher (Multi-chain Blockchain Developer API) MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my BlockCypher (Multi-chain Blockchain Developer API) payment history." If connected, Cascade will call the BlockCypher (Multi-chain Blockchain Developer API) tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about BlockCypher (Multi-chain Blockchain Developer API) MCP in Windsurf

You add the server configuration to your Windsurf MCP settings file. Once connected, Cascade automatically discovers all fifteen blockchain tools and invokes them during your active coding sessions.

Yes. Cascade uses `new_transaction` to generate the unsigned skeleton transaction. You sign it locally, and Cascade uses `send_transaction` to broadcast it to the network.

Ask Cascade to monitor an address, and it uses this MCP connection to call `create_webhook` to establish real-time alerts. This lets you receive instant updates directly in your workspace when network events occur.

No. A single BlockCypher token handles Bitcoin, Ethereum, and testnets. You can verify your current plan limits anytime by letting Cascade run `get_token_info`.

Your private keys never leave your local Windsurf environment. Vinkius runs the MCP Server inside an isolated sandbox, keeping your API tokens secure while passing only public addresses and signed hex data to the BlockCypher endpoints.
