What is MCP Obsidian Server?
The MCP Obsidian Server gives Claude read and write access to an Obsidian vault stored on disk. It can list notes, read note content, create and update notes, search by text content, and retrieve backlinks.
Read the full overview
Works directly on the vault directory without requiring the Obsidian app to be running. Useful for knowledge management workflows where Claude needs to recall notes, add new observations, and update a personal knowledge base as part of a research or writing workflow.

Key capabilities
Note access
List all notes in the vault, read note content as Markdown, create new notes with frontmatter, and update existing notes. Append content to a note without overwriting the full file.
Search
Full-text search across the vault and backlink retrieval: find all notes that link to a given note. Useful for navigating a large vault and discovering related context.
Where MCP Obsidian Server fits
Compatible with Claude Desktop, Cursor, Cline, and any MCP-compatible client. Install via npm (npx) or pip (uvx) depending on the server implementation language.
Positioning and limitations
A popular choice among knowledge workers who use Obsidian as their second brain and want Claude to contribute to it. Lets the AI read relevant notes before answering a question, and write new notes from a conversation summary.
MCP servers extend AI clients beyond their training data by giving them access to live systems: local files, databases, APIs, and services. Each server adds a set of typed tools the AI can call, inspect results from, and chain into multi-step workflows, all within a single conversation context.
