OpenClaw Obsidian Integration: Knowledge Graph and Notes Automation

Obsidian is a knowledge management tool built on plain markdown files with a powerful linking system. Because Obsidian vaults are just folders of .md files, OpenClaw can integrate with them directly — no API required on the same machine. This makes it one of the simplest and most powerful OpenClaw integrations available.

This guide covers both integration methods and shows you how to turn your Obsidian vault into an AI-powered knowledge base you can query from WhatsApp or any messaging channel.

What Does the OpenClaw Obsidian Integration Do?

• Create notes — "Create a note about today's meeting with Sarah" generates a formatted markdown note with frontmatter
• Search vault — "What do my notes say about pricing strategy?" searches across all your notes
• Append to notes — "Add this to my daily journal" appends content to existing notes
• Graph queries — "What notes are linked to the Q1 Planning note?" traverses your knowledge graph
• Auto-linking — OpenClaw can suggest and create wiki-links between related notes
• Daily notes — automatically generate or update daily notes with information from your conversations

What Do You Need Before Starting?

• A running OpenClaw instance on the same machine as your Obsidian vault (or with file access to it)
• An Obsidian vault (any folder of markdown files)
• For REST API method: the Local REST API community plugin

How Do You Connect OpenClaw to Obsidian?

Method A — Direct file access (recommended for servers)

tools:
  obsidian:
    enabled: true
    method: "file"
    vault_path: "/Users/you/Documents/MyVault"
    default_folder: "Inbox"
    daily_notes_folder: "Daily Notes"
    daily_notes_format: "YYYY-MM-DD"
    template_folder: "Templates"

That is the entire setup. OpenClaw reads and writes markdown files directly. No plugin or API needed.

Method B — Local REST API (for advanced features)

Step 1 — Install the plugin

In Obsidian, go to Settings → Community Plugins → Browse and search for "Local REST API". Install and enable it. Note the API key and port (default 27124).

Step 2 — Configure OpenClaw

tools:
  obsidian:
    enabled: true
    method: "rest_api"
    api_url: "https://localhost:27124"
    api_key: "your-rest-api-key"

Step 3 — Test

openclaw start

Message your bot: "Create a note called Test Note with the content Hello World." Check your vault for the new file.

What Can You Automate With OpenClaw and Obsidian?

• Meeting notes — after a call, dictate key points and OpenClaw creates a structured note with tags and links
• Research capture — "Save this article summary to my Research folder" while browsing on your phone
• Daily journaling — automated daily note creation with calendar summary, weather, and task list
• Knowledge Q&A — "What were the key decisions from last month's board meeting?" queries your vault
• Zettelkasten workflow — create atomic notes and have OpenClaw suggest links to related concepts
• Project documentation — "Create a project page for the new website redesign" with templates

How Do You Fix Common Obsidian Issues?

• File permission errors: Ensure the user running OpenClaw has read/write access to the vault directory. On macOS, you may need to grant Full Disk Access.
• Notes not appearing in Obsidian: If using direct file access, Obsidian may need a moment to detect new files. Clicking into a folder or restarting Obsidian triggers a refresh.
• Wiki-links not resolving: Make sure OpenClaw uses the correct note title format. Obsidian wiki-links are case-sensitive and match file names without the .md extension.
• REST API connection refused: The Local REST API plugin must be active (Obsidian must be open). Check that the port is not blocked and the API key matches.
• Large vault search is slow: For vaults with 10,000+ files, enable OpenClaw's file indexing feature or use the ripgrep-based search instead of full-text scanning.

FAQ

Does OpenClaw need Obsidian to be running?

It depends on the integration method. Direct file access works without Obsidian running since it reads and writes markdown files directly. The Local REST API method requires Obsidian to be open with the plugin active. For always-on server deployments, direct file access is recommended.

Can OpenClaw search across my entire Obsidian vault?

Yes. OpenClaw can search file contents, frontmatter properties, tags, and note titles across your entire vault. For large vaults (10,000+ notes), consider indexing with a local search tool like ripgrep for faster results.

Will OpenClaw break my Obsidian links and formatting?

No. OpenClaw understands Obsidian's wiki-link syntax ([[note]]), frontmatter YAML, and markdown formatting. It creates and edits notes in native Obsidian format, preserving existing links and metadata.

Can I use OpenClaw with Obsidian Sync?

Yes, but with a caveat. If OpenClaw writes to the vault while Obsidian Sync is active, changes will be synced to all devices. This is generally desirable, but be aware that simultaneous edits from multiple devices could cause sync conflicts. OpenClaw works best as the sole editor on the server vault.
