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.

MCP Slim is a proxy that replaces full MCP tool catalogs with three meta-tools (search, describe, call), using local MiniLM embeddings for semantic search. It achieves 96% context window reduction and works offline without API keys.
Sovr MCP Proxy adds safety layer to prevent LLM destructive commands
A developer built sovr-mcp-proxy after a local LLM nearly executed rm -rf on their home folder. The tool intercepts commands before execution and blocks destructive patterns including rm -rf, DROP TABLE, curl | sh, and chmod 777.
