Compatible with every major AI agent and IDE
What is the GetBlock (Web3 RPC Provider) MCP Server?
Connect your GetBlock account to any AI agent and interact with dozens of blockchain protocols through natural conversation. GetBlock provides high-performance RPC node access for developers and crypto enthusiasts.
What you can do
- Multi-Chain Queries — Fetch data from Ethereum, Solana, Bitcoin, and 50+ other supported networks using specialized tools.
- Account & Balance Tracking — Check native balances and token holdings across different chains (e.g.,
eth_get_balance,sol_get_balance). - Blockchain Inspection — Retrieve block details, transaction receipts, and blockchain metadata (e.g.,
eth_block_number,btc_get_blockchain_info). - Advanced Debugging — Access deep transaction traces and call simulations to analyze smart contract behavior (e.g.,
debug_trace_transaction). - Generic RPC Access — Use the
rpc_calltool to execute any JSON-RPC method supported by the GetBlock nodes.
How it works
- Subscribe to this server
- Enter your GetBlock Access Token (API Key)
- Start querying blockchain data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Web3 Developers — debug transactions and check contract states without leaving your code editor.
- Crypto Analysts — pull real-time on-chain data and block statistics for reporting and research.
- DeFi Users — monitor wallet balances and transaction statuses across multiple protocols via a single interface.

Frequently asked questions
Can I query blockchains other than Ethereum?
Yes! This server includes specific tools for multiple networks, such as sol_get_balance for Solana and btc_get_blockchain_info for Bitcoin, leveraging GetBlock's multi-chain infrastructure.
How do I execute a custom RPC method not listed in the tools?
Use the rpc_call tool. You can provide the method name (e.g., 'eth_chainId') and a JSON string of parameters to interact with any available endpoint feature.
Is it possible to debug failed smart contract transactions?
Yes. Use the debug_trace_transaction tool with the transaction hash. It will return the execution traces, helping you identify exactly where a call reverted or failed.
How does Windsurf discover MCP tools?
Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.
Can Cascade chain multiple MCP tool calls?
Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.
Does Windsurf support multiple MCP servers?
Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.
Server not connecting
Check Settings → MCP for the server status. Try toggling it off and on.
