Alchemy MCP Server

by fernforge Your server? Claim it
local only

Alchemy runs on your own machine — the client starts it, so there is no endpoint to ping. 47 installs a week from npm. Last commit 5 Jul 2026.

Serves the Alchemy writing ruleset to any agent, so its prose loses the usual LLM tells.

Nothing serious here today

Today is the operative word: we check Alchemy every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Alchemy — questions

Answers built from our own checks of this server.

Why is there no uptime for Alchemy?
Alchemy runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @fernforge/alchemy-mcp was installed 47 times last week.
How do I connect Alchemy?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @fernforge/alchemy-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Alchemy?
The npm package @fernforge/alchemy-mcp was installed 47 times in the last week. Week over week that is -6%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Alchemy open source?
Yes — it is published under the MIT licence, written in JavaScript and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
