Using explicit AWS credentials and a Qdrant API key:

uvx --from git+https://github.com/KanvaBhatia-Alaan/alaan-slack-index-mcp-tool slack-indexed \
  --aws-access-key AKIA... \
  --aws-secret-key wJal... \
  --qdrant-url http://your-qdrant-host:6333 \
  --qdrant-api-key your-qdrant-api-key

Local development
