Alchemy MCP Server — Claude Code MCP server: setup and features
Hosted MCP server connecting AI agents to Alchemy onchain data across 100+ chains with OAuth authentication and zero local setup.
claude mcp add --transport http mcp https://mcp.alchemy.com/mcpWhat Alchemy MCP Server does
This service links development assistants directly to blockchain networks via https://mcp.alchemy.com/mcp. It exposes token valuations, transaction traces, transfer logs, and NFT information across 100+ distributed ledgers, including Solana DAS endpoints.
Alchemy retired its local npm distribution @alchemy/mcp-server, setting its shutdown date for September 30, 2026. The new cloud endpoint handles Streamable HTTP requests natively. You do not need to store an ALCHEMY_API_KEY in environment variables anymore, because authentication happens via browser OAuth using your Alchemy profile.
What it helps with
- inspect wallet token balances and incoming transfer logs
- simulate transaction execution before broadcasting to mainnet
- retrieve NFT asset data using Solana DAS methods
- inspect EVM call traces for failing smart contracts
Example prompts for the agent
- Check recent ERC-20 transfers for address
0x... - Simulate this contract interaction on Polygon and show trace logs
- Fetch NFT collection details using Solana DAS
