Cursor utilise le même schéma mcpServers que Claude Desktop. La config projet l'emporte sur la globale.

Cas d'usage

Usages concrets : Unstructured UNS MCP

Stand up a RAG pipeline from a SharePoint folder to Pinecone

👤 Data engineers / RAG builders ⏱ ~15 min intermediate

Quand l'utiliser : You have a corporate doc dump and want a Claude-queryable index.

Prérequis

Server/skill installed and authenticated — See repo README

Déroulement

Define the pipeline

Create an Unstructured pipeline: source SharePoint folder X, partition by_title with 1024 token max, embed with text-embedding-3-small, target Pinecone index 'corp-docs'.✓ Copié

→ Pipeline id
Run and monitor

Run it and tell me when it's done. Report any failed documents.✓ Copié

→ Status updates + final summary

Résultat : Production-grade ingest with proper chunking — not naive PDF text dumps.

Pièges

Default chunkers can split tables across chunks. For dense tabular docs, use 'by_title' with combine_text_under_n_chars. — Default chunkers can split tables across chunks. For dense tabular docs, use 'by_title' with combine_text_under_n_chars.
