Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

[!IMPORTANT] The legacy local MCP server has been retired. Its source code has been removed from this repository, and the @alchemy/mcp-server npm package will stop working on September 30, 2026. Use the hosted Alchemy MCP Server at https://mcp.alchemy.com/mcp instead.

The hosted Alchemy MCP Server gives AI agents access to Alchemy's blockchain APIs and onchain data. It authenticates via OAuth — just sign in with your Alchemy account when prompted. No API key or local install required.

Why it matters. a network transport with no auth environment variable found
Fix. require a token

Questions

What is the Alchemy MCP server?

Alchemy's official MCP Server. Allow AI agents to interact with Alchemy's blockchain APIs.

Is Alchemy safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Alchemy need?

No credential environment variables were found in its source, so it appears to need none.

How does Alchemy run?

It speaks streamable-http, so it runs as a service you connect to over the network.

How current is this page?

The grade is for one exact copy of the source (abf5692daae9), read on 2026-10-07. The repository is watched and re-audited when it changes.
