What is the Obsidian Omnisearch MCP server?

A FastMCP-based server that provides Obsidian vault search functionality through a REST API interface. Exposed over MCP by the obsidian omnisearch mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

This project implements a search service that allows you to search through Obsidian vault notes programmatically. It uses FastMCP to expose the search functionality as a tool that can be integrated with other services.

  • Search through Obsidian vault notes
  • REST API integration
  • Returns absolute paths to matching notes
  • Easy integration with FastMCP tools

Its toolset

Everything the assistant can do here goes through one of these:

  • Debugging — Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the [MCP

Configuration

You will need one environment variable: UV_PUBLISH_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

  • Python 3.x - Obsidian with Omnisearch plugin installed and running - FastMCP library - Active Obsidian vault

Adding it to your client

Installation goes through your MCP client rather than a global install: point it at @smithery/cli on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

When to reach for it

Among the planning and project tracking options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Obsidian Omnisearch's toolset — Debugging — is a fair guide to whether it matches your workflow. It is maintained by anpigon; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Obsidian Omnisearch's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the obsidian omnisearch mcp server does with a few real requests.

How to install the Obsidian Omnisearch MCP server

{
  "mcpServers": {
    "server-obsidian-omnisearch": {
      "command": "npx",
      "args": ["-y", "@smithery/cli"],
