AI coding assistants

Connect to live blockchain data,
node management, and Chainstack docs.
All from a single MCP endpoint.

Just tell your AI agent:

get mcp.chainstack.com

Build faster with Chainstack in your agent

No API key required

These tools work from the first prompt — no account, no credit card.

  • Docs search — RPC methods, guides, and code examples
  • Platform status — live health, incidents, and maintenance
  • Live pricing — plan tiers, add-ons, and the dedicated-node catalog
  • Contact — sales or support, without leaving the chat

API key required

The full platform unlocks with a key from your Chainstack account.

  • Deploy nodes — create, inspect, and delete, with live RPC endpoints
  • Manage projects — organize nodes across projects and your organization
  • Deployment options — every chain, cloud, and region combination
  • Testnet faucet — top up addresses on Sepolia, Solana devnet, and more

Your AI assistant is one command away from live blockchain infrastructure

Common questions about the Chainstack MCP server
Does the Chainstack MCP server need an API key to get started?

No. Five tools work without any authentication: search_docs, get_doc_page, get_platform_status, get_chainstack_pricing, and contact_chainstack. Node lifecycle tools — creating, listing, and deleting nodes — require a Chainstack API key. Get one from Settings > API keys in your Chainstack account.

Which blockchains does it support?

The MCP server inherits Chainstack’s full chain coverage — Ethereum, Solana, BNB Smart Chain, Base, Arbitrum, Polygon, Hyperliquid, Monad, MegaETH, and 70+ additional chains including testnets and archive-enabled networks.

Does it require any local installation?

No. The Chainstack MCP server runs as a remote Streamable HTTP server at https://mcp.chainstack.com/mcp. Any AI coding assistant that supports HTTP MCP transports connects directly — no binary download, no package install, no Docker image required.

Can my AI assistant deploy production nodes?

Yes. With a Chainstack API key, your AI assistant can create, inspect, and delete both Global Nodes and Trader Nodes on any supported chain. Nodes deployed via the MCP server appear in your Chainstack console exactly like any manually created node.

How do I get my Chainstack API key?

Sign in to your Chainstack account and go to Settings > API keys. Generate a key and pass it as an authorization header when making authenticated MCP calls. Free-tier accounts get full access to all unauthenticated tools immediately.

What is Chainstack MCP

Chainstack MCP server (Model Context Protocol) is a server integration that connects Chainstack’s blockchain infrastructure with modern AI-assisted development platforms such as Claude, Cursor, OpenAI Codex, and Gemini. By using MCP, developers can seamlessly query on-chain data, manage nodes, and search documentation without leaving their coding environment.

The MCP server acts as a bridge between your AI agent and the blockchain tools you already rely on. Instead of manually switching between APIs, explorers, and documentation, you can query live chain data, deploy nodes, and search Chainstack docs directly from your workflow.

Chainstack MCP is designed for flexibility and performance. Whether you are building DeFi trading bots, analyzing on-chain data, or deploying production infrastructure, MCP streamlines the process by providing unified access to all supported chains and methods — at mcp.chainstack.com.
