GetBlock (Web3 RPC Provider)

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_call tool to execute any JSON-RPC method supported by the GetBlock nodes.

How it works

  1. Subscribe to this server
  2. Enter your GetBlock Access Token (API Key)
  3. 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.

Why OpenAI Agents SDK?

The OpenAI Agents SDK auto-discovers all 26 tools from GetBlock (Web3 RPC Provider) through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries GetBlock (Web3 RPC Provider), another analyzes results, and a third generates reports, all orchestrated through Vinkius.

  • Native MCP integration via MCPServerSse, pass the URL and the SDK auto-discovers all tools with full type safety

  • Built-in guardrails, tracing, and handoff patterns let you build production-grade agents without reinventing safety infrastructure

  • Lightweight and composable: chain multiple agents and MCP servers in a single pipeline with minimal boilerplate

  • First-party OpenAI support ensures optimal compatibility with GPT models for tool calling and structured output

FAQ

Frequently asked questions

01

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.

02

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.

03

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.

04

How does the OpenAI Agents SDK connect to MCP?

Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.

05

Can I use multiple MCP servers in one agent?

Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.

06

Does the SDK support streaming responses?

Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.

07
