When the host has multiple Python interpreters — e.g. a pre-built agent venv at /opt/venv-agent, a Spartan module load Python/3.11.3, or an existing ~/.venv you want to leave alone — point uv at the exact interpreter you want with --python:

# install into a specific venv WITHOUT touching project-local .venv
uv pip install --python /opt/venv-agent/bin/python "scitex-dataset[all]"

# one-shot CLI run under that interpreter
uv run --python /opt/venv-agent/bin/python scitex-dataset list-python-apis

# install the CLI as a tool, pinned to the same interpreter
uv tool install --python /opt/venv-agent/bin/python "scitex-dataset[mcp]"

# in a downstream script that bootstraps scitex-dataset, honour
# SCITEX_PYTHON if the caller sets it:
SCITEX_PYTHON="${SCITEX_PYTHON:-/opt/venv-agent/bin/python}"
uv pip install --python "$SCITEX_PYTHON" "scitex-dataset[all]"

The Makefile honours PYTHON=:

PYTHON=/opt/venv-agent/bin/python make install

AI agents can discover and query neuroscience datasets autonomously.

_{Table 2. 21 MCP tools across catalog fetchers, HuggingFace, the dataset index, and skill introspection. Every MCP tool has a matching public Python alias (e.g. scitex_dataset.openneuro_fetch).}
