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.

Why AutoGen?
AutoGen enables multi-agent conversations where agents negotiate, delegate, and collaboratively use GetBlock (Web3 RPC Provider) tools. Connect 26 tools through Vinkius and assign role-based access. a data analyst queries while a reviewer validates, with optional human-in-the-loop approval for sensitive operations.
- —
Multi-agent conversations: multiple AutoGen agents discuss, delegate, and collaboratively use GetBlock (Web3 RPC Provider) tools to solve complex tasks
- —
Role-based architecture lets you assign GetBlock (Web3 RPC Provider) tool access to specific agents. a data analyst queries while a reviewer validates
- —
Human-in-the-loop support: agents can pause for human approval before executing sensitive GetBlock (Web3 RPC Provider) tool calls
- —
Code execution sandbox: AutoGen agents can write and run code that processes GetBlock (Web3 RPC Provider) tool responses in an isolated environment

Why teams choose Vinkius for GetBlock (Web3 RPC Provider) in AutoGen
The GetBlock (Web3 RPC Provider) MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 26 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in AutoGen only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
GetBlock (Web3 RPC Provider) for AutoGen
Every tool call from AutoGen to the GetBlock (Web3 RPC Provider) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call GetBlock (Web3 RPC Provider) tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
