How to Use the GetBlock (Web3 RPC Provider) MCP in Windsurf

Q: Can I execute custom JSON-RPC methods using GetBlock (Web3 RPC Provider) inside Windsurf?

Yes, Cascade runs the rpccall tool to send any arbitrary JSON-RPC payload to GetBlock's supported networks. You get raw JSON back, which Windsurf parses to update your UI or debug backend services.

Run multi-chain balance checks and debug smart contracts autonomously inside Windsurf using Cascade and GetBlock.

Audit multi-chain balances with Windsurf Cascade

`eth_get_balance`, `sol_get_balance`, and `btc_getblockcount` feed live blockchain metrics directly into your Cascade workspace. Windsurf reads your local context, identifies the wallet addresses in your code, and gets the exact balances across Ethereum, Solana, and Bitcoin in one autonomous pass. You don't copy-paste addresses into block explorers anymore. Cascade processes the raw balance data to update your local configuration files or alert you to low-funded testnet accounts. This MCP integration turns static wallet files into live, self-updating assets during development.

Debug EVM execution paths using this MCP Server

`debug_trace_transaction` and `debug_trace_call` let your agent extract full execution traces without running a local Geth archive node. Windsurf reads the transaction hash from your test output, calls the RPC endpoint, and inspects the exact EVM state changes. You get the precise line of Solidity that caused the revert in seconds. Cascade chains this debugging data with local file modifications to fix the underlying smart contract bug. The agent writes the patch, runs a local test suite, and verifies the fix without you prompting each step.

Build and sign transactions natively in Cascade

`btc_createpsbt` and `sol_send_transaction` allow Windsurf to construct valid transaction payloads and broadcast them to live networks. The agent generates the raw hex or payload based on your target parameters, then waits for your manual signature before broadcasting. You skip the manual CLI scripting or web wallet interfaces entirely. Cascade monitors the transaction status using `eth_get_transaction_receipt` to confirm successful block inclusion. If the transaction stalls, the agent automatically estimates gas again and prepares a replacement.

Setup guide

Set up GetBlock (Web3 RPC Provider) 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 GetBlock (Web3 RPC Provider) 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 GetBlock (Web3 RPC Provider) payment history." If connected, Cascade will call the GetBlock (Web3 RPC Provider) tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about GetBlock (Web3 RPC Provider) MCP in Windsurf

Cascade uses the server to fetch live state directly into your coding loop. Instead of manually writing mock APIs or switching to a browser, the agent runs queries like `eth_call` to verify your smart contract logic against mainnet state instantly.

Yes, Cascade runs the `rpc_call` tool to send any arbitrary JSON-RPC payload to GetBlock's supported networks. You get raw JSON back, which Windsurf parses to update your UI or debug backend services.

No, Vinkius handles the credentials for the GetBlock (Web3 RPC Provider) MCP Server under a single endpoint token. Windsurf connects to this managed gateway, giving Cascade instant access to all three chains without hardcoding secrets in your codebase.

Windsurf manages tool execution pacing based on the endpoint's response headers. If an RPC call returns a rate-limiting status, Cascade pauses and retries the operation, keeping your development flow running without crashing.

This MCP Server only transmits public wallet addresses, transaction hashes, and raw hex payloads to the GetBlock RPC endpoints. It never touches your private keys, seed phrases, or local keystore files, keeping your funds safe within your local environment.
