Alchemy

Blockchain data across 100+ chains: token prices, NFTs, transfers, simulation, traces, Solana DAS

Alchemy MCP Server

Give your AI coding agent direct access to 100+ blockchains with 159 tools through the Model Context Protocol.

For the complete documentation index, see llms.txt.

The Alchemy MCP Server connects your AI tools to blockchain data through the Model Context Protocol (MCP). It exposes 159 tools across token prices, NFT metadata, transaction history, smart contract simulation, tracing, account abstraction, Solana DAS, and more — covering 100+ networks including Ethereum, Base, Polygon, Arbitrum, Optimism, Solana, and Starknet.

Connect your client

The server runs at https://mcp.alchemy.com/mcp and authenticates via OAuth — just sign in with your Alchemy account when prompted. No API key or local install required.

{` .mcp-client-tabs [role="tablist"] { display: flex; width: 100%; } .mcp-client-tabs [role="tablist"] > [role="tab"] { flex: 1 1 0; display: flex; align-items: center; justify-content: center; text-align: center; } `}

Add the server:

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

Restart Claude Code (or start a new conversation).
Select alchemy and authenticate:

/mcp

You should see alchemy in the list of active MCP servers. The first time you use a tool, a browser window will open to sign in with your Alchemy account.

Add the server:

codex mcp add alchemy --url https://mcp.alchemy.com/mcp

Verify it was added:

codex mcp list

Add to Cursor

Add the following JSON to your MCP config file:

Cursor: ~/.cursor/mcp.json (global) or .cursor/mcp.json (project-level)

{
  "mcpServers": {
    "alchemy": {
      "type": "streamable-http",
      "url": "https://mcp.alchemy.com/mcp"
    }
  }
}

Restart your editor after saving. For Cursor, you can also verify via Cursor Settings > MCP.

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "alchemy": {
      "type": "streamable-http",
      "url": "https://mcp.alchemy.com/mcp"
    }
  }
}

Restart Claude Desktop after saving.

Add to .vscode/mcp.json in your project:

{
  "servers": {
    "alchemy": {
      "type": "http",
      "url": "https://mcp.alchemy.com/mcp"
    }
  }
}

For any other MCP-compatible client, point it at https://mcp.alchemy.com/mcp using Streamable HTTP transport. The server supports OAuth 2.1 with PKCE — your client will handle the authorization flow automatically.

Getting started

Once connected, sign in with your Alchemy account when prompted. Then the typical workflow is:

Tell your agent which app to use — e.g. "Select an Alchemy app"
Ask your agent — e.g. "What's the current price of ETH?" or "Show me the NFTs owned by vitalik.eth"
