Notion vs Obsidian: MCP servers compared
Which one works better with Claude, ChatGPT and other AI assistants? Here is what each vendor publishes, side by side, from our dated verdicts.
The short answer
- Only Notion publishes an official MCP server. Obsidian is "community only" as of Oct 2026.
- Notion is listed as a Claude connector; the other is not.
- Notion's server is hosted, so there is nothing to install. The other runs differently.
- Notion documents more tools (8 vs 7 for Obsidian).
- Safety flags to review: Notion 1, Obsidian 3. See each verdict for details.

Notion verdict
As of October 2026, Notion runs an official hosted MCP server at mcp.notion.com/mcp, and Anthropic lists it as a verified Claude connector made by Notion. It uses OAuth and works on every Notion plan, with some features limited to Business or Enterprise. It can create, edit and delete pages. The older open-source npm server is no longer maintained.
Setup, tools and safety check for Notion →Obsidian verdict
As of October 2026, no official Obsidian MCP server was verified. Obsidian ships its own CLI for scripting and agentic tools, but that is not MCP. Community servers, such as MarkusPfundstein/mcp-obsidian, run locally and talk to your vault through the Local REST API plugin using an API key, and can delete notes.
