--package fastapi --query "dependency injection"
Search with specific registry
uv run python -m runtime.harness scripts/mcp/nia_docs.py \
--package react --registry npm --query "hooks patterns"
Grep search for specific patterns
uv run python -m runtime.harness scripts/mcp/nia_docs.py \
--package sqlalchemy --grep "session.execute"
Universal search across indexed sources
uv run python -m runtime.harness scripts/mcp/nia_docs.py \
--search "error handling middleware"
