5 use cases

  • Browse and query a database from the terminal

    Open a database in a keyboard-driven client and run SQL with completion and query plans.

    View prompt
    In the masume repo, open the database at <target> with `masume <target>` and run `select count(*) from <table>`. Expected output: a single row with a count. Verify the count matches the table size reported by the database.

  • Let an external agent query allowed databases over MCP

    Serve chosen profiles to an agent over stdio with an access level per profile.

    View prompt
    Using the masume MCP server for profile <profile>, list the tables and report the row count of <table>. Expected output: a table list and one integer. Verify the count by running a matching count query in masume yourself.

  • Run SQL in a script and export results to a file

    Run statements headless and write CSV, JSON, or Parquet output for a pipeline.

    View prompt
    In the masume repo, run `masume run -p <profile> -f json 'select count(*) from <table>'` and report the JSON output. Expected output: one JSON result with a count. Verify that the exit code is 0 before the next step uses the output.

  • Compare the schemas of two databases

    Find differences in tables, columns, indexes, and constraints between two connections.

    View prompt
    Run `masume diff <source> <target>` in the masume repo and summarize the differences found. Expected output: a list of schema differences. Verify one reported difference by inspecting that table in both databases.

  • Find and open databases running in local containers

    Detect databases in running Docker or Podman containers and open one in the client.

    View prompt
    In the masume repo, run `masume --detect` and report the databases it lists. Expected output: a list of detected databases. Verify that the database you expect appears, and that the container is running.
