Testing drs

Prerequisites

  • Python 3.11+
  • uv package manager
  • Dremio Cloud account with a PAT and project ID

Setup

  1. Install dependencies:

    uv sync

  2. Create config file at ~/.config/dremioai/config.yaml:

    pat: dremio_pat_xxxxxxxxxxxxx
project_id: your-project-id

    Or export env vars:

    export DREMIO_PAT=dremio_pat_xxxxxxxxxxxxx
export DREMIO_PROJECT_ID=your-project-id

Unit tests

uv run pytest tests/ -v

All unit tests use mocked HTTP — no Dremio Cloud connection needed.

Smoke tests (requires live Dremio Cloud)

Query

drs query run "SELECT 1 AS test_value"
drs query run "SELECT 1" --output csv
drs query run "SELECT 1" --output pretty

Catalog

drs catalog list
drs catalog search "orders"
drs catalog get "your_space.your_table"

Schema

drs schema describe "your_space.your_table"
drs schema sample "your_space.your_table"
drs schema lineage "your_space.your_table"
drs schema describe-source "your_space.your_table"

Reflections

drs reflect list "your_space.your_table"

Jobs

drs jobs list
drs jobs list --status FAILED --limit 5

Access

drs access roles
drs access whoami
drs access grants "your_space.your_table"

MCP server verification

  1. Start the server:

    drs mcp

    (Should block on stdio — Ctrl+C to stop)

  2. Test with Claude Desktop: add the MCP config from README.md, restart Claude Desktop, verify all 13 tools appear.

  3. Filtered start:

    drs mcp --services query,schema

    Only dremio_query_* and dremio_schema_* tools should appear.
