Which integrations are available for this server?

Stores notes as Markdown files compatible with Obsidian vaults, enabling integration with Obsidian.

memex

npm license node

Local-first second brain with semantic search. Stores notes as Markdown files and indexes them with a local ML model — no cloud, no API keys.

Works as an MCP server for Claude Code and Claude Desktop, and as a standalone CLI.

Features

Semantic search — multilingual embeddings via paraphrase-multilingual-MiniLM-L12-v2 (Korean + English, runs fully offline)
Obsidian-compatible — notes saved as .md files in your vault directory
MCP server — Claude can save and search your second brain mid-conversation
CLI — add, search, list, show, delete notes from the terminal
Local DB — SQLite + sqlite-vec stored inside the vault at .memex/memex.db

Install

npm install -g @evan-moon/memex

On first run the embedding model (~120MB) is downloaded once to ~/.memex/models/.

CLI

memex add                                   # interactive prompt
memex add --title "Note title" --content "..." 
memex add --title "Note title" --file ./note.md
memex add --title "Note title" --content "..." --folder "projects/memex"

memex list                                  # recent 10 notes
memex list --limit 20

memex search "semantic search query"        # multilingual
memex search "지식 관리" --limit 10

memex show <id>
memex delete <id>
memex delete --yes <id>                     # skip confirmation

memex config show
memex config set vault-path ~/Documents/Second\ Brain

memex mcp install                           # register with Claude Code
memex mcp path                              # print MCP binary path
