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 CrewAI?

When paired with CrewAI, GetBlock (Web3 RPC Provider) becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call GetBlock (Web3 RPC Provider) tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.

  • Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools

  • CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the mcps parameter and agents auto-discover every available tool at runtime

  • Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls

  • Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

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 CrewAI discover and connect to MCP tools?

CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.

05

Can different agents in the same crew use different MCP servers?

Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.

06

What happens when an MCP tool call fails during a crew run?

CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.

07

Can CrewAI agents call multiple MCP tools in parallel?

CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.

08

Can I run CrewAI crews on a schedule (cron)?

Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.

09

MCP tools not discovered

Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.

10

Agent not using tools

Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".

11

Timeout errors

CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.

12

Rate limiting or 429 errors

Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
