Alchemy

Overview

Alchemy is a Model Context Protocol server that applies a writing ruleset to help AI agents produce prose without typical language model tells. Any MCP-compatible assistant can call Alchemy's tools directly during conversations or agent runs, letting the model decide when to apply the ruleset for more natural, human-like output.

The server runs locally via the npm package @fernforge/alchemy-mcp, communicating over stdio on your machine. No credentials or setup beyond installation are needed. Version v0.1.1 is available under the MIT license, with source code at fernforge/alchemy on GitHub.

Alchemy is listed in the AI & Agents category on mcp.site and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Alchemy for fernforge, claim this listing to verify ownership and keep information accurate.
