Memory Management Database
Provides a LibSQL-based persistent memory database for storing and retrieving knowledge graph entities and relations across conversations.
  1. Determine Your Database Type
    • Decide whether you will use a local SQLite database or a remote libSQL (such as Turso) database.

If using a local SQLite database:

  1. Locate or Create Your Database File

    • Choose a path for your SQLite database file (e.g., /path/to/your/database.db).
    • You can use any .db file—create a new one or use an existing one.

  2. Set the Database URL

    • Set the LIBSQL_URL value to point to your SQLite file in the following format: 
      file:/path/to/your/database.db
    • If using WSL, ensure you use the Linux filesystem format for paths (e.g., /home/username/database.db).

If using a remote libSQL database (such as Turso):

  1. Create a Remote Database

    • Sign up or log in to your remote libSQL provider (e.g., Turso).
    • Create a new database following their instructions.

  2. Obtain Your Database Connection URL

    • After creating your database, find the connection URL for your database.
    • It will look like: 
      libsql://your-database.turso.io

  3. Obtain Your Authentication Token

    • Generate or locate the authentication token for your database on your provider’s dashboard.
    • Copy the token (it may be labeled as “API Token,” “Auth Token,” or similar).

  1. Add ENVs in FastMCP

    • In the FastMCP connection interface, use the "Install Now" button to add your environment variables.
    • Fill in the following fields:
      • LIBSQL_URL: Use either the local file path (for SQLite) or the remote URL (for libSQL/Turso).
      • LIBSQL_AUTH_TOKEN (only for remote): Paste your auth token.
    Variable Example Value
    LIBSQL_URL file:/path/to/database.db
    (or) libsql://your-database.turso.io
    LIBSQL_AUTH_TOKEN your-auth-token

  2. Save and Apply

    • Save your ENV values. The server will now connect to your specified database.

Note:

  • If you do not specify any LIBSQL_URL, the default is file:/memory-tool.db in the current directory.
  • For full details and graphical steps, refer to your libSQL provider’s documentation, such as the Turso Quickstart Guide.
