obsidian-mcp: Graph-Aware MCP Server for Claude with 25 Tools Targeting Large Vaults
Built by u/One-Classroom-9261, obsidian-mcp is an MCP server that gives Claude graph-aware access to your Obsidian vault. Unlike most integrations that only expose read_file and write_file — which forces the model to make ~50 read calls to answer a simple connection question and fills your context window — this server exposes the vault's graph structure directly.
Key Tools
get_note— returns content + backlinks + forward links + tags + frontmatter in a single calltraverse_graph— walk N hops out from a notequery_dataview— run DQL (Dataview Query Language) directlymove_note— rename + rewrite every incoming wiki-link so the graph survivescreate_notes— batch-scaffold a Map of Content (MOC) plus topical notes in one shot
Total: 25 tools. Compatible with Claude Desktop, Claude Code, Cursor, Cline, Continue, and Zed.
Setup
If you already have the Local REST API plugin installed in Obsidian, setup takes about 60 seconds. The project is MIT licensed, runs locally, and nothing leaves your machine.
The author built it in ~24 hours, notes there are rough edges, and welcomes feedback.
