Manage your RAG pipelines in Claude Desktop

View all your available pipelines by calling `list_pipelines`. Once you identify the correct ID, use `get_pipeline` to inspect the configuration before you start executing searches. Trigger your search workflows instantly with `run_pipeline`. This allows you to pass inputs directly from your conversation into your production deepset Cloud environment.

Query document indexes inside Claude Desktop

Use `search_documents` to pull relevant context from your indexed data. It cuts out the need to manually export files or switch tabs just to find specific information. Verification is simple with `list_files` and `get_file`. You can confirm metadata and file status without leaving the Claude Desktop interface.

Navigate deepset Cloud workspaces

Switch between environments by using `list_workspaces`. This keeps your development, staging, and production data context clear while you work. Everything stays organized within your chat flow. You get the exact data you need from your Haystack (deepset Cloud) setup without any extra steps.
