Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

Casos de uso

Usos do mundo real: cocoindex-claude

Build your first CocoIndex pipeline from a local folder into a vector DB

👤 Developers evaluating CocoIndex for a RAG use case ⏱ ~30 min intermediate

Quando usar: You've read the CocoIndex homepage and want Claude to scaffold a working flow instead of copy-pasting tutorials.

Pré-requisitos

Skill cloned to ~/.claude/skills/cocoindex-claude — git clone https://github.com/cocoindex-io/cocoindex-claude ~/.claude/skills/cocoindex-claude
cocoindex Python package installed — pip install cocoindex

Fluxo

Describe the pipeline

Use the cocoindex skill — scaffold a flow that watches ./docs, chunks markdown, embeds with OpenAI, writes to Qdrant.✓ Copiado

→ Claude generates a flow.py with @cocoindex.flow_def and the right source/transform/export calls
Run and verify

Now show me the exact CLI commands to build, run, and incrementally update this flow.✓ Copiado

→ cocoindex setup / update / eval commands in the correct order

Resultado: A working flow.py plus the commands to run it — no more guessing at the CocoIndex decorator surface.

Armadilhas

Claude invents APIs that don't exist in CocoIndex — Explicitly prompt 'use only APIs documented in the cocoindex skill' — hallucination drops when the skill is in scope

Combine com: filesystem

Write a custom CocoIndex transform function

👤 Engineers extending an existing CocoIndex flow ⏱ ~25 min intermediate

Quando usar: Built-in transforms don't cover your parsing / enrichment step.

Fluxo

Describe the transform

With the cocoindex skill — write a @cocoindex.op.function that takes a PDF path, extracts tables, returns structured rows.✓ Copiado

→ Idiomatic function signature with correct typed inputs/outputs
Wire it into the flow

Now plug this into my existing flow at the chunking stage.✓ Copiado

→ Diff against current flow.py with the new op in place

Resultado: A custom transform that obeys CocoIndex's incremental semantics.

Armadilhas

Function returns non-deterministic output, breaking incremental processing — Skill reminds Claude that transforms must be pure — if you hit this, re-read the incremental section

Combinações

Combine com outros MCPs para 10× de alavancagem

cocoindex-claude-skill + filesystem

Let Claude actually write the flow.py file to disk, not just print it in chat

Scaffold the CocoIndex flow and save it to ./pipelines/docs_to_qdrant.py.✓ Copiado

cocoindex-claude-skill + postgres

Pipe CocoIndex output into a Postgres vector store and query it from the same session

Build the flow targeting pgvector, then run a retrieval query against it.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar
scaffold_flow	source type + sink type + transform steps	Starting a new pipeline
write_custom_op	function intent + input/output types	Built-in transforms aren't enough
cli_guidance	task (setup / update / eval / drop)	You're unsure whether to rebuild or incrementally update

Custo e limites

O que custa rodar

Cota de API: None
Tokens por chamada: Modest — skill loads reference material only when relevant
Monetário: Free — skills are local files
Dica: CocoIndex itself is free; costs come from your embedding model and vector DB, not this skill.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: No credentials — pure prompts

Saída de dados: None from the skill itself. Your pipeline calls whichever embedding / DB services you configure.

Solução de problemas

Erros comuns e correções

Skill not invoked when you ask about CocoIndex

Say 'use the cocoindex skill' explicitly, or check it's installed at ~/.claude/skills/cocoindex-claude.

Verificar: ls ~/.claude/skills/cocoindex-claude/SKILL.md

SKILL.md frontmatter wrong

Open the file and verify name / description are populated. Re-clone if partial.

Verificar: head ~/.claude/skills/cocoindex-claude/SKILL.md

Wrong trigger keywords — Claude writes generic Python instead of CocoIndex

Mention CocoIndex explicitly, or say 'scaffold a cocoindex flow_def'.

Alternativas

cocoindex-claude vs. outros

Alternativa	Quando usar	Troca
LlamaIndex skills	You want LlamaIndex's retrieval abstractions instead of CocoIndex's transform-centric model	Different mental model — LlamaIndex is retrieval-first, CocoIndex is pipeline-first
Hand-written Python	You need one-off processing and don't want incremental state	No incremental rebuilds, no framework conventions
