Examples

Connecting to a Memos Instance

"Connect to my Memos instance at https://memos.example.com with the API key abc123"

The AI will use the connect_instance tool to save the connection:

• Host: https://memos.example.com

• Name: A friendly name (e.g., personal, work)

• API Key: Your access token from Memos → Settings → My Account → Access Tokens

Searching Across All Instances

"Find all memos containing 'project ideas' in all my memos instances"

The server will query all connected instances and return matching results.

Querying a Specific Instance

"Create a new memo in my work-memos instance about the meeting today"

The server will create the memo only in the specified instance.

Using Filters

"List all archived memos with the #important tag"

The server supports CEL filter expressions for advanced queries.
