Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-obsidian-second-brain save a memory about the quarterly planning session"
That's it! The server will respond to your query, and you can continue using it as needed.

An MCP (Model Context Protocol) server that gives Claude a persistent, structured memory system backed by an Obsidian vault. Memories are stored as Markdown files with YAML frontmatter using the PARA method (Projects, Areas, Resources, Archives).

"args": ["-y", "@neverprepared/mcp-obsidian-second-brain"],
"env": {
"OBSIDIAN_VAULT_PATH": "/path/to/your/obsidian/vault"
}
}
}
}git clone https://github.com/neverprepared/mcp-obsidian-second-brain.git
cd mcp-obsidian-second-brain
npm install
npm run buildThen add to your Claude Desktop config:
{
