README

obsidian-web-mcp

A secure, remote-accessible MCP server that gives LLMs read/write access to your Obsidian vault from anywhere -- your desktop, your phone, a hotel Wi-Fi network. Unlike local-only Obsidian MCP servers, this one runs over HTTPS with real authentication, so Claude (or any MCP client) can reach your vault whether you're at your desk or not.

It reads and writes markdown files on disk, parses YAML frontmatter, maintains an in-memory frontmatter index for fast queries, and handles full-text search -- all behind OAuth 2.0 authentication and a Cloudflare Tunnel that never exposes your machine directly to the internet.

Why This Exists

There are many Obsidian MCP servers. Most are local stdio servers -- they work when Claude Code is running on the same machine as your vault. That's useful, but it means:

Claude.ai (web) can't reach your vault. The browser-based Claude has no way to connect to a local stdio server.
Claude on your phone can't reach your vault. Same problem.
If you use Obsidian Sync, local MCP servers can corrupt files. Non-atomic writes create partial files that Sync propagates to every device.

This server solves all three. It runs as a persistent HTTP service on the machine where your vault lives, tunneled securely through Cloudflare, and authenticates via OAuth 2.0 -- the same protocol Claude uses for Gmail, Google Calendar, and other integrations. The result: your vault becomes a first-class MCP connector available everywhere Claude is.
