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

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "lessie-skill": {
      "command": "git",
      "args": [
        "clone",

      ],
      "_inferred": true
    }
  }
}

Clique no ícone MCP Servers na barra lateral do Cline, depois "Edit Configuration".

Mesmo formato do Claude Desktop. Reinicie o Windsurf para aplicar.

    }

O Continue usa um array de objetos de servidor em vez de um map.

Adicione em context_servers. Zed recarrega automaticamente ao salvar.

Uma linha só. Verifique com claude mcp list. Remova com claude mcp remove.

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar	Custo
find-people	title / company / domain / location filters	Starting from ICP filters	Lessie plan-dependent
enrich-contact	person id or profile	Shortlist narrowed and ready to contact	Per-enrichment credit
find-company	company name or domain + optional filters	Account research before outreach	Plan-dependent
send-email	Gmail/Outlook account + to/subject/body	Only after you review drafts — don't auto-send at scale	Uses your own mailbox

Custo e limites

O que custa rodar

Cota de API: Depends on Lessie plan — the skill itself is just the prompt wrapper
Tokens por chamada: Moderate; responses can be large when listing 50+ contacts
Monetário: Free — skills are local files. Lessie's data API is paid; consult current plans.
Dica: Filter aggressively before enrichment; every enrichment call costs credits.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: Lessie API key in env var; Gmail/Outlook via OAuth if you use send-email

Saída de dados: Queries go to Lessie's API. Email sending goes via your provider.

Contact enrichment must comply with GDPR / CAN-SPAM / local laws — Lessie provides data, compliance is on you.
Don't automate bulk sends without warming; volume without domain reputation = spam folder.

Solução de problemas

Erros comuns e correções

Skill not invoked — Claude offers generic LinkedIn advice

Say 'use lessie-skill' explicitly.

Verificar: ls ~/.claude/skills/lessie-skill/SKILL.md

SKILL.md frontmatter wrong

Re-clone; description drives activation.

Verificar: head ~/.claude/skills/lessie-skill/SKILL.md

Wrong trigger keywords — enrichment runs before filtering narrows the list

Explicitly: 'first find-people, then I'll pick who to enrich'.

Alternativas

lessie-skill vs. outros

Alternativa	Quando usar	Troca
Apollo.io / Clay	You want a full GTM suite with sequencing tools	Much heavier platforms; pricier
LinkedIn Sales Navigator	LinkedIn-native prospecting with InMail	Expensive, no agent integration
