What it does
The server provides a bridge between AI agents and Alchemy's blockchain APIs, exposing 97 tools for querying on-chain data. Agents can fetch token prices and history, retrieve NFT ownership and contract metadata, view transaction histories, check balances across multiple networks, and list asset transfers with filtering. Two deployment modes are available: a hosted remote server at mcp.alchemy.com (no local setup required) or a local STDIO server for private deployments.
Who it's for
Web3 engineers, DApp developers, and AI researchers who need to query live blockchain data within Claude workflows. Useful for building agents that analyze on-chain activity, research token and NFT positions, or automate blockchain queries without writing custom RPC clients.
Common use cases
- Query current and historical token prices by symbol or contract address
- Fetch token balances and ownership across Ethereum, Base, and other supported networks
- Retrieve transaction and asset transfer histories for wallet addresses
- Look up NFT holdings and collection metadata for given addresses
- Send transactions via Smart Contract Accounts (requires wallet agent configuration)
- Execute decentralized exchange swaps programmatically
Setup pitfalls
ALCHEMY_API_KEYenvironment variable is required; obtain one from alchemy.comsendTransactionandswapmethods require a separate wallet agent server endpoint for signing and broadcasting- Security scanner detected 2 embedded secrets in the codebase — audit before production use
- Hosted server at mcp.alchemy.com and the open-source repository are maintained separately and may diverge
