Ouvrez Claude Desktop → Settings → Developer → Edit Config. Redémarrez après avoir enregistré.

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

  }
}

Cliquez sur l'icône MCP Servers dans la barre latérale Cline, puis "Edit Configuration".

Même format que Claude Desktop. Redémarrez Windsurf pour appliquer.

    }

}

Continue utilise un tableau d'objets serveur plutôt qu'une map.

Ajoutez dans context_servers. Zed recharge à chaud à la sauvegarde.

Une seule ligne. Vérifiez avec claude mcp list. Supprimez avec claude mcp remove.

Cas d'usage

Usages concrets : mcp-documentation-server

Make a new framework's docs queryable by your AI

👤 Devs adopting a new library ⏱ ~20 min beginner

Quand l'utiliser : Official docs are huge; you want Claude to answer with grounded citations.

Prérequis

mcp-documentation-server installed — npx -y @andrea9293/mcp-documentation-server

Déroulement

Ingest the docs

Upload the library's docs .md files to the dashboard at http://localhost:3080.✓ Copié

→ Files processed into chunks
Ask targeted questions

search_documents for 'how to configure middleware' — give me the top 3 chunks with source paths.✓ Copié

→ Cited excerpts
Ask grounded synthesis

Given those chunks, write the minimum viable config for middleware in this framework.✓ Copié

→ Working config backed by cited doc lines

Résultat : A personal docs assistant that cites its sources.

Pièges

PDFs with scanned images aren't OCR'd — Pre-OCR with tools like ocrmypdf before upload
Huge doc sets without Gemini give noisy embeddings — Optional GEMINI_API_KEY unlocks higher-quality semantic search

Combiner avec : filesystem

Turn an internal wiki export into a RAG source

👤 Teams with markdown-export-friendly wikis ⏱ ~25 min beginner

Quand l'utiliser : You've exported your Notion/Confluence content as Markdown and want AI access.

Déroulement

Bulk-ingest via process_uploads

process_uploads on ./wiki-export/ — process every .md.✓ Copié

→ Document count per folder
Full-scope search

search_all_documents: 'deployment runbook' — top 5.✓ Copié

→ Ranked list

Résultat : A local, private, searchable wiki.

Build a personal research-paper library

👤 Researchers, students ⏱ ~30 min beginner

Quand l'utiliser : You download papers and want them queryable instead of piled in Downloads/

Déroulement

Drop PDFs in

Upload all PDFs in ~/Papers/ to the documentation server.✓ Copié

→ Papers chunked and indexed
Ask across corpus

search_documents: 'attention variants with lower quadratic cost' — return authors + years.✓ Copié

→ Cited excerpts

Résultat : A local mini-perplexity over your own paper collection.

Combinaisons

Associez-le à d'autres MCPs pour un effet X10

documentation-server + filesystem

Automate ingest from a watched folder

Every time a new PDF lands in ~/Papers/Inbox, process_uploads it into the documentation server.✓ Copié

documentation-server + swarmvault

Compare: documentation-server is quick-ingest; swarmvault builds a structured wiki

Ingest my research PDFs into both systems; compare retrieval quality on the same query.✓ Copié

Outils

Ce que ce MCP expose

Outil	Entrées	Quand appeler	Coût
add_document	title, content, metadata?	Programmatic ingest	free (local embeddings)
list_documents	(none)	See what's indexed	free
get_document	id	Retrieve a specific doc	free
delete_document	id	Pruning	free
search_documents	query, top_k?	Query within a specific doc set	free
search_all_documents	query, top_k?	Global RAG query	free
get_context_window	chunk_id	Expand a narrow hit into broader context	free
search_documents_with_ai	query	One-shot answer synthesis	Gemini call (needs key)
process_uploads	path?: str	Batch import from the uploads folder	free

Coût et limites

Coût d'exécution

Quota d'API: None if local; Gemini usage if GEMINI_API_KEY set
Tokens par appel: Search returns 500-3000 tokens depending on top_k
Monétaire: Free; Gemini is paid per-call if enabled
Astuce: Skip Gemini for exploratory work — local embeddings are good enough for known-item lookups.

Sécurité

Permissions, secrets, portée

Stockage des identifiants : GEMINI_API_KEY (optional) in env

Sortie de données : Local only unless Gemini is enabled; dashboard on port 3080

Dashboard on :3080 has no auth — bind to localhost only.
Document content sits in the MCP_BASE_DIR as JSON; treat it like any local data.

Dépannage

Erreurs courantes et correctifs

Port 3080 in use

Set WEB_PORT env var to another port.

Vérifier : lsof -i :3080

PDF parse error

Password-protected or scanned PDFs fail. Remove password or run OCR first.

Vérifier : Try a plain PDF

search returns empty

Check documents ingested: list_documents. If empty, re-run process_uploads.

Vérifier : list_documents

Alternatives

mcp-documentation-server vs autres

Alternative	Quand l'utiliser	Compromis
swarmvault	You want a structured wiki + knowledge graph, not just search	Heavier; more upfront setup
Cloud RAG (Pinecone, Weaviate)	You need team-shared, scale	Paid; data leaves your machine
llm-context.py	You want per-task context, not persistent doc retrieval	Different problem
