Setup — do this once

Step 1: Create a private GitHub repo for the vault

1. Go to github.com → New repository
2. Name it galaxy-vault, set it to Private
3. Do NOT initialize with README

Step 2: Install Obsidian Git and push the vault

1. In Obsidian: Settings → Community Plugins → Browse → search "Obsidian Git" → Install → Enable
2. Open the Obsidian Git settings:
   • Auto pull interval: 5 (minutes)
   • Auto push interval: 5 (minutes)
   • Commit message: vault: auto-sync {{date}}
3. Run command palette → "Obsidian Git: Initialize a new repo"
4. Run command palette → "Obsidian Git: Open source control view"
5. Stage all → Commit → set remote to your new private repo URL → Push

After this, every edit to the vault auto-pushes to GitHub within 5 minutes.

Step 3: Create a GitHub Personal Access Token

1. github.com → Settings → Developer Settings → Personal access tokens → Fine-grained tokens
2. Name: galaxy-mcp
3. Repository access: select galaxy-vault only
4. Permissions: Contents → Read-only
5. Copy the token

Step 4: Deploy to Railway

1. Go to railway.app → New Project → Deploy from GitHub repo → select this galaxy-mcp repo
2. Add environment variables (Settings → Variables):

GITHUB_TOKEN=   (the token from step 3)
GITHUB_OWNER=   (your GitHub username)
GITHUB_REPO=    galaxy-vault
API_KEYS=       (two random keys, comma-separated — run `openssl rand -hex 32` twice)

3. Railway will auto-deploy. Copy your public URL (e.g. https://galaxy-mcp-production.up.railway.app)

Connecting to ChatGPT (Custom GPT)

ChatGPT doesn't speak MCP natively. Add it as a Custom Action:

1. Create a Custom GPT → Configure → Add Action
2. Import schema from: https://your-railway-url.up.railway.app/openapi.json
3. Auth: API Key → Bearer → paste API key

(The server serves an OpenAPI schema automatically at /openapi.json)
