Lex

Overview

Lex is a Model Context Protocol (MCP) server: Episodic memory, Frames, Policy Neighborhoods, and policy enforcement for AI agents. In practice that means any MCP-compatible AI assistant can call Lex's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package @smartergpt/lex-mcp speaks MCP over stdio on your machine. The current release is v4.0.4, published under the MIT license, with source at Guffawaffle/lex on GitHub.

Lex is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
