What is the Obsidian MCP server?

Connect Obsidian to Claude, Cursor or any other MCP client and it stops being a tab you switch to. MCP server for Obsidian vaults that survives iCloud — reads, searches and writes notes without hanging on evicted files. The obsidian mcp server is what makes that connection.

Installation

obsidian-vault-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • obsidian_list_notes — List Markdown notes, optionally under a subdirectory
  • obsidian_search_notes — Full-text search with path, line number and excerpt
  • obsidian_read_note — Read one note
  • obsidian_create_note — Create a note; refuses to overwrite
  • obsidian_update_note — Atomic overwrite of an existing note
  • obsidian_vault_health — Materialized vs evicted counts, bytes pending, largest evicted notes — stat-only, never blocks
  • obsidian_warm_notes — Opt-in background downloads for evicted notes, bounded per call

Credentials and setup notes

Configuration is passed through the environment: OBSIDIAN_VAULTS. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Worth knowing first

  • 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.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

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's toolset — obsidian_list_notes, obsidian_search_notes, obsidian_read_note and 4 more — is a fair guide to whether it matches your workflow. It is maintained by qebellavita; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
