## About

Alchemy's hosted MCP server gives AI agents access to its blockchain APIs across more than 100 networks, including EVM and Solana RPC, token balances and prices, NFT data, asset transfers, transaction simulation and tracing, and smart wallets. It is remote and authenticates with OAuth using your Alchemy account; the older local npm server is being retired.
