What is the QuickNode MCP Server?

Connect your QuickNode account to any AI agent to orchestrate Web3 infrastructure through natural language. This server provides a comprehensive suite of tools to manage high-performance blockchain data pipelines and queries.

What you can do

  • Streams Management — Create, list, and update real-time data streams for historical and live blockchain ingestion using create_stream and list_streams.
  • Webhooks — Deploy webhooks from templates (like EVM wallet filters or contract events) to deliver real-time events to your HTTP endpoints via create_webhook.
  • KV Store — Manage key-value pairs and lists to power advanced server-side filtering logic for your streams using create_kv_list and create_kv_set.
  • Core RPC — Access fundamental blockchain data, such as retrieving the most recent block number using rpc_eth_blocknumber.

How it works

  1. Subscribe to this server
  2. Provide your QuickNode API Key and RPC URL
  3. Start building and monitoring your Web3 infrastructure from Claude, Cursor, or any MCP client

Who is this for?

  • Web3 Developers — Rapidly prototype and manage data pipelines without leaving the terminal or IDE.
  • Data Engineers — Orchestrate complex blockchain data ingestion workflows using natural language commands.
  • DevOps Teams — Monitor and update infrastructure configurations, webhooks, and streams on the fly.

Why Pydantic AI?

Pydantic AI validates every QuickNode tool response against typed schemas, catching data inconsistencies at build time. Connect 18 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.

  • Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application

  • Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your QuickNode integration code

  • Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors

  • Dependency injection system cleanly separates your QuickNode connection logic from agent behavior for testable, maintainable code

FAQ

Frequently asked questions

01

How do I check the current block height on Ethereum?

You can use the rpc_eth_blocknumber tool. It will return the most recent block number from the blockchain network connected to your RPC URL.

02

Can I create a stream to monitor specific blockchain datasets?

Yes, use the create_stream tool. You can specify the dataset (e.g., 'block', 'traces') and the destination (e.g., 'webhook', 's3') to start ingesting data immediately.

03

How do I manage lists for my stream filters?

Use the create_kv_list tool to initialize a list and update_kv_list to add or remove items. These lists can be referenced in your Streams JavaScript filter functions.

04

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

05

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

06

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your QuickNode MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
