## What it 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.
