How to Set Up and Use Alchemy

The Alchemy MCP Server connects AI agents to Alchemy's suite of blockchain APIs, enabling real-time queries for token prices, NFT ownership, multi-chain balances, transaction history, and asset transfers. It also supports sending transactions and executing DEX swaps on Uniswap when paired with a wallet agent server. Developers building Web3 applications or conducting on-chain research can use this server to drive blockchain lookups conversationally without writing custom API calls.

Prerequisites

  • Node.js 18 or later installed (for npx usage)
  • An Alchemy account and API key from https://dashboard.alchemy.com
  • Optional: AGENT_WALLET_SERVER endpoint if you need transaction sending or DEX swaps
  • An MCP client such as Claude Desktop, Claude Code, or Cursor
1

Obtain your Alchemy API key

Sign in to the Alchemy dashboard at https://dashboard.alchemy.com, create or select an app, and copy the API key shown on the app overview page.

2

Run the MCP server with npx

The simplest way to start the server is via npx, which downloads and runs the latest published package without a global install.

npx -y @alchemy/mcp-server
3

Configure your MCP client (Claude Desktop)

Add the Alchemy server to your Claude Desktop configuration file. Set the ALCHEMY_API_KEY environment variable to your key. If you need wallet operations, also set AGENT_WALLET_SERVER.

{
  "mcpServers": {
    "alchemy": {
      "command": "npx",
      "args": ["-y", "@alchemy/mcp-server"],
      "env": {
        "ALCHEMY_API_KEY": "your_alchemy_api_key_here"
      }
    }
  }
}

Alternative: connect via HTTP transport

For remote or shared deployments, Alchemy also hosts the MCP server as an HTTP endpoint. Use the claude mcp add command to register it directly.

claude mcp add alchemy --transport http https://mcp.alchemy.com/mcp
5

Restart your MCP client and verify the connection

Restart Claude Desktop (or reload your MCP client). Open a conversation and ask a blockchain question to confirm the server is responding.

Alchemy Examples

Client configuration

Full Claude Desktop JSON config for the Alchemy MCP server using npx with the required API key.

{
  "mcpServers": {
    "alchemy": {
      "command": "npx",
      "args": ["-y", "@alchemy/mcp-server"],
      "env": {
        "ALCHEMY_API_KEY": "your_alchemy_api_key_here",
        "AGENT_WALLET_SERVER": "https://your-wallet-server.example.com"
      }
    }
  }
}

Prompts to try

Example prompts that exercise the server's blockchain query capabilities.

- "What is the current price of Ethereum and Bitcoin?"
- "Show me all NFTs owned by wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum."
- "What tokens does 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 hold across Ethereum and Base?"
- "Get the transaction history for address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045."
- "Show ETH price history from January 1st 2025 to today with daily intervals."

Troubleshooting Alchemy

401 Unauthorized errors when calling blockchain APIs

Verify that ALCHEMY_API_KEY is correctly set in your MCP client config. Check that the key belongs to an active Alchemy app and that the app has the required network enabled in the Alchemy dashboard.

Transaction sending or swap operations fail with missing server errors

Transaction and DEX swap tools require the AGENT_WALLET_SERVER environment variable to be set to a running wallet agent endpoint. These tools do not work with just the ALCHEMY_API_KEY alone.

npx hangs or fails to download the package

Ensure you have a stable internet connection and Node.js 18+. Try clearing the npx cache with 'npm cache clean --force' and re-running 'npx -y @alchemy/mcp-server'.
