Reviewer Notes

Obsidian Sync is primarily a consumer-facing service without developer-oriented API documentation or MCP integration. There is no public REST API, OpenAPI spec, or structured programmatic access for agents to authenticate, manage vaults, or trigger syncs. Account creation requires human interaction (OAuth through Obsidian account creation). The service is not designed for autonomous agent operation and lacks the infrastructure (SDKs, webhooks, API endpoints) that would enable meaningful agent integration. The paid subscription model also requires upfront payment without trial or sandbox environment for agent testing.
