概要

What is Alchemy MCP Server?

This open-source Model Context Protocol server bridges AI agents with Alchemy's blockchain APIs, enabling queries for token prices, NFT ownership, transaction history, token balances, and asset transfers across multiple networks. It also supports sending transactions and executing token swaps via Smart Contract Accounts (requires external wallet infrastructure). A hosted remote version at https://mcp.alchemy.com/mcp is recommended; a local STDIO version is available as legacy.

How to use Alchemy MCP Server?

To use the recommended hosted server, point your MCP client to https://mcp.alchemy.com/mcp with Streamable HTTP transport and authenticate via OAuth — no API key required. The local STDIO server runs via npx -y @alchemy/mcp-server and requires the ALCHEMY_API_KEY environment variable. For transaction and swap methods, also set AGENT_WALLET_SERVER to a configured wallet agent server.

A transaction auditor retrieving transfer history with advanced filters.
A DeFi assistant initiating swaps and transfers via Smart Contract Accounts.

FAQ from Alchemy MCP Server

How does this server differ from directly calling Alchemy's REST APIs?

It abstracts Alchemy's blockchain APIs into an MCP interface, allowing AI agents to call them via natural language prompts instead of manual HTTP requests.

What are the runtime requirements?

The hosted server needs no local installation. The local STDIO server requires Node.js and an Alchemy API key. For transactions and swaps, a separate wallet agent server is required.

Where does data live?

All data is fetched live from Alchemy's blockchain APIs. The server acts as a real-time bridge with no local storage.

Are there any known limits?

The local STDIO server is legacy and not actively maintained. It may lag behind the hosted server's tool coverage and behavior. Alchemy plans to sunset this repository.

What transports and authentication are supported?

The hosted server uses Streamable HTTP transport with OAuth authentication. The local server uses STDIO transport and authenticates via an API key environment variable.
