Deploy a Relay MCP server to the user's own Railway account, giving Claude read/write access to their Obsidian vault via the Relay.md sync protocol. Bundled source ships inside the skill — no separate repo clone needed. The user only pastes a Railway account token; the relay vault and folders inside it are auto-discovered after they OAuth in. Use when the user wants to "set up the os MCP", "deploy relay MCP to railway", "self-host the obsidian MCP server", or…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# OS MCP — Railway Deploy

This skill deploys the Relay MCP v2 server to the user's own Railway account. The MCP source is bundled at `${CLAUDE_PLUGIN_ROOT}/skills/os-mcp/reference/relay-mcp-server/` — copy from there, do not fetch from anywhere else. The deployed server lets Claude clients (Claude Code or claude.ai) read/write the user's Obsidian vault by talking to the Relay.md sync protocol.

## What the user provides

**One thing: a Railway account token** — created at `https://railway.com/account/tokens`.

That's it. After deploy, the user signs in with their Relay.md credentials via OAuth; the MCP then auto-discovers their relay vault and the folders inside it via PocketBase. No vault GUIDs, no folder maps.

How to install

The exact contents, by fingerprint

mdr add naveedharri/benai-skills/os-mcp@sha256:e5590e35cafcac42

The line at the top of this page pins the label git:20260916.a3b1e15, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
