Cursor usa el mismo esquema mcpServers que Claude Desktop. La configuración del proyecto prevalece sobre la global.

VS Code → Cline → MCP Servers → Edit

  "mcpServers": {
    "zotero-mcp": {
      "command": "uvx",
      "args": [
        "zotero-mcp"
      ]
    }
  }
}

Haz clic en el icono MCP Servers de la barra lateral de Cline y luego en "Edit Configuration".

Mismo formato que Claude Desktop. Reinicia Windsurf para aplicar.

Continue usa un array de objetos de servidor en lugar de un mapa.

    }
  }
}

Añádelo a context_servers. Zed recarga en caliente al guardar.

Casos de uso

Usos del mundo real: Zotero MCP

Synthesize a literature review from tagged papers

👤 Grad students, researchers ⏱ ~60 min intermediate

Cuándo usarlo: You've tagged 30 papers with #thesis-ch3 and need to write section 3.2.

Requisitos previos

Zotero running (local API enabled) — Zotero 7: Settings → Advanced → enable local API
API key if using web — zotero.org/settings/keys

Flujo

Pull the set

List every item tagged thesis-ch3 in my Zotero. Just titles + years + first author.✓ Copiado

→ Clean inventory, ~30 items
Cluster

Group those by methodological approach. Cite each item by zotero key.✓ Copiado

→ 3–5 clusters with per-cluster citations
Extract + write

For cluster "quantitative RCTs", pull my highlights from each item and draft a synthesis paragraph with in-line citations.✓ Copiado

→ Paragraph with (Author, Year) citations backed by actual highlights

Resultado: A drafted section 3.2 you can edit instead of starting from blank.

Errores comunes

PDF has no highlights, just scans — Run OCR in Zotero first (right-click → OCR PDF), then re-pull

Combinar con: filesystem

Generate the bibliography for a paper you're writing

👤 Anyone writing with LaTeX ⏱ ~15 min beginner

Cuándo usarlo: You've cited 40 items across a draft and need a single references.bib.

Flujo

Scan for cites

In /paper/main.tex, list every \cite{} key.✓ Copiado

→ All cite keys enumerated
Resolve

For each, pull BibTeX from Zotero and write the result to /paper/references.bib. Flag any key with no match.✓ Copiado

→ bib file written; unresolved cites listed

Resultado: A clean references.bib tied to your Zotero — no manual copy-paste.

Errores comunes

Cite key mismatch (Better BibTeX vs default) — Install the Better BibTeX extension in Zotero for stable pinned keys

Combinar con: filesystem

Combinaciones

Combínalo con otros MCPs para multiplicar por 10

zotero-mcp + filesystem

Write the extracted synthesis to your paper draft

Write the synthesis from Zotero into /paper/section-3-2.md.✓ Copiado

zotero-mcp + memory

Remember per-paper key arguments across sessions

Store the 1-sentence thesis of each item from cluster A in memory.✓ Copiado
