second-brain MCP

Overview

second-brain MCP is a Model Context Protocol server that creates a self-maintaining knowledge vault for your AI assistants. It brings figure-level search, auto-wikilinks, and memory compression to Claude, Cursor, VS Code, and other MCP clients, letting them build and navigate your personal knowledge base as they work.

The server runs locally on your machine via the mcp-second-brain package, installed with uvx mcp-second-brain. It requires no credentials and works immediately over stdio with zero setup friction. Version v0.1.0 is available under the MIT license, with source code at ddmanyes/second-brain-mcp on GitHub.

second-brain MCP is listed in the Memory category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP-compatible client. If you maintain this server, claim your listing to verify ownership and keep it up to date.
