Obsidian REST API

Operate Obsidian via Local REST API plugin from WSL or remote environments.

First-Time Setup

On first use, automatically detect and save configuration:

1. Check TOOLS.md for existing OBSIDIAN_API_URL and OBSIDIAN_API_KEY
2. If not found:
   • Get Windows host IP: cat /etc/resolv.conf | grep nameserver | awk '{print $2}'
   • Ask user for API Key
   • Save to TOOLS.md:

     ### Obsidian REST API (WSL → Windows)
     **API 端点**: https://\x3Cdetected-ip>:27124
     **API Key**: \x3Cuser-provided-key>
     

3. Test connection with saved config
