Query RAG pipelines from Claude Desktop

The `query_pipeline` tool lets Claude Desktop execute natural language searches against your active LlamaCloud setups. By running this MCP server, you don't have to write custom API scripts. You ask your agent to fetch answers from your indexed documents, and it handles the payload construction on the fly. This means you get grounded answers in your chat window without leaving the workspace. The tool returns exact source context, letting your agent synthesize responses based on real-world data instead of guessing.

Audit source files inside your workspace

The `list_files` and `list_indexes` tools give your local Claude Desktop client direct visibility into what data has actually been ingested. You can verify if a specific PDF is in the index before running a search, saving time on debugging missing context. Straight to the point: if a query fails, you run these checks to see if the file is even there. Your agent pinpoints whether the file is missing from the index or if the pipeline configuration itself needs adjusting.

Inspect active LlamaCloud configurations

The `list_pipelines`, `list_projects`, and `get_pipeline` tools expose your remote LlamaIndex structures directly to your workspace. Your agent pulls down active project IDs through the MCP interface and inspects pipeline nodes to understand how data flows. This setup turns your chat interface into a control plane for your RAG architecture. You don't have to keep the LlamaCloud dashboard open in a browser tab when you want to verify pipeline settings.
