Run this in your terminal

claude mcp add smart-connections --env VAULT_PATH=your-value -- npx -y @gogogadgetbytes/smart-connections-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{

Common questions

Is Smart Connections safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: VAULT_PATH

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 9 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

Smart Connections MCP Server

A security-first MCP server for Smart Connections. Read-only. Path-validated. Auditable.

Exposes Smart Connections embeddings to Claude Code and other MCP clients for semantic search of your Obsidian vault.

Why This Exists

We needed semantic search of our Obsidian vault from Claude Code. Existing options have problems:

No path validation - User input passed directly to file operations
Write access - Some expose mutation tools we don't need
Heavy dependencies - PyTorch/transformers for what's essentially vector math

This implementation:

Minimal dependencies - MCP SDK + Transformers.js (for text search)
Fail-closed security - path validation with realpath, symlink detection
Auditable - small TypeScript codebase you can actually read

Features

Text search - query with plain text, not just note paths
Semantic search using Smart Connections embeddings
Local inference - uses Transformers.js (same model as Smart Connections)
Read-only - no write operations, no shell execution
Secure - strict path validation, bounded responses
Offline - works without Obsidian running

Security Model

Property	Guarantee
Path confinement	All file access validated against vault root
No traversal	`../` and symlink attacks blocked
Read-only	No write operations exposed
Bounded responses	Capped results (50), content length (10KB)
Fail closed	Errors deny access, never bypass
Audit logging	Security events logged with context

Installation

Prerequisites

Node.js 18+
Obsidian with Smart Connections plugin installed
Embeddings built (open vault in Obsidian, let Smart Connections index)

Setup

git clone https://github.com/gogogadgetbytes/smart-connections-mcp

cd smart-connections-mcp npm install npm run build

Configure Claude Code

Add to your Claude Code config:

claude mcp add smart-connections \

-e VAULT_PATH="/path/to/your/obsidian/vault" \ -- node /path/to/smart-connections-mcp/dist/index.js

Or manually add to ~/.claude.json:

"mcpServers": { "smart-connections": { "command": "node", "args": ["/path/to/smart-connections-mcp/dist/index.js"], "env": { "VAULT_PATH": "/path/to/your/obsidian/vault" } } } }

Restart Claude Code to load the server.

Usage

Once configured, Claude Code can use these tools:

Search by Text

"Search my vault for notes about backup strategies"

→ Uses search_by_text tool

Search Similar Notes

"Find notes similar to Topics/Claude_Code.md"

→ Uses search_similar tool

Get Note Content

"Show me the content of Topics/Obsidian.md"

→ Uses get_note tool

List Indexed Notes

"What notes are indexed in my vault?"

→ Uses list_indexed tool

Tools

Tool	Description
`search_by_text`	Search using freeform text (computes embedding locally)
`search_similar`	Find notes semantically similar to a given note
`search_by_embedding`	Search using a raw embedding vector
`get_note`	Get content of a specific note (path validated)
`get_model_info`	Get embedding model configuration
`list_indexed`	List all indexed notes

Configuration

Variable	Required	Description
`VAULT_PATH`	Yes	Absolute path to Obsidian vault

Limitations

Single vault - Configure one vault per MCP server instance
Index from Smart Connections - Note embeddings come from the plugin; text queries are embedded locally
No write access - By design; use Obsidian for edits
First run downloads model - ~50MB model cached in ~/.cache/huggingface/
