### Description (declared)

# Obsidian Blade MCP

An [MCP](https://modelcontextprotocol.io) server that gives any MCP client, such as Claude Desktop, Claude Code or a headless agent, precise tools over an [Obsidian](https://obsidian.md) vault. When Obsidian is running it uses the official Obsidian CLI and Obsidian's own index. When Obsidian is closed, or the host has no Obsidian at all, it reads and writes the vault directory directly. Same 40 tools either way, read-only unless you opt in to writes, and it never launches Obsidian for you.

## Why this exists

Most Obsidian integrations need the desktop app open, a community plugin installed, or a REST bridge running. That is fine on a laptop and useless on a server, in CI, or on a machine where Obsidian is simply closed. This server works in all of those places. On a desktop with Obsidian open it defers to Obsidian's index, so search, Bases and the link graph are exactly what you see in the app. Everywhere else it falls back to a deterministic parser over the Markdown files: frontmatter, wikilinks, tags, tasks, daily notes and templates, with no embeddings, no inference and no network.

It is also built for agents rather than for people typing commands. Output is compact and capped, every response says which backend answered, writes are off until an operator turns them on, destructive operations dry-run first, and every edit can be guarded by a content hash so an agent never overwrites a note a human changed underneath i…
