“Convenient cloud collaboration and AI integration | Notion”
“provides an official hosted MCP server.”
“The assistant authenticates through OAuth.”
“Enterprise plans offer additional MCP governance controls.”

“Read-only configuration | Limited | Yes | Plugin-dependent | Implementation-dependent | Connection-dependent”
“Local execution | No | Yes | Yes | Yes | No”
“Flexible personal knowledge base with folder restrictions | Obsidian”
“The important security advantage is that you can restrict which parts of your vault the assistant can access.”
“is particularly interesting because your notes are ordinary Markdown files stored locally.”
“The plugin runs locally and uses Obsidian APIs rather than giving the external assistant unrestricted filesystem access.”
“Official MCP | Yes | Yes | No | Yes | Yes”
“offers an official MCP integration.”
“This is a good candidate if you prefer a local-first knowledge management system rather than a cloud-based workspace.”
“The main consideration is that you need to protect the API key and check the available tool permissions before enabling write access.”
“provides an MCP integration through its hosted service.”
“This is convenient if you want an assistant to work with your notes from different devices without maintaining a local MCP server.”
“Local execution | No | Yes | Yes | Yes | No”
“Maximum control over individual tools | Joplin”
“You can individually enable or disable:”
“Localhost-only network access (127.0.0.1).”
“This makes Joplin particularly attractive if you want to start with read-only access and gradually enable additional capabilities.”
“One important caveat: Joplin does not itself ask you to confirm each write operation. If you enable editing, the connected AI application can execute it directly.”
