É o isolamento da ADR 0001 e continua assim. Mas um dono que quer que o bot SDR leia o LinkedIn, ou que o bot de suporte consulte o próprio sistema, não tinha como. Esta seção deixa o **dono** cadastrar um servidor MCP e ligá-lo a bots escolhidos. O Botloft o acrescenta ao `mcp.json` gerado; o `--strict-mcp-config` fica. + +No app, o nome é **Ferramentas conectadas** (15.6: sem "MCP" nem "servidor" na tela, e "Detalhes" guarda o técnico). + +### 25.2 Cadastro + +- **Só o dono, pelo app.** Não existe tool MCP, mensagem nem arquivo do workspace que cadastre ou ligue um servidor: um bot não consegue se dar ferramentas novas, nem a outro bot. O `mcp.json` do bot é regenerado a cada start (5.1) e o que o bot escrever nele se perde. +- **Dois tipos**, os do Claude Code: `http` (`url`, `headers`) e `stdio` (`command`, `args`, `env`). `sse` fica de fora (o Claude Code o marca como obsoleto, 19). +- **Colar o que já existe.** O diálogo aceita o trecho `{"mcpServers": {...}}` do `.mcp.json` ou do `claude mcp add-json`, que é o que o dono já tem; um servidor por entrada. Campo desconhecido é recusado, não ignorado. +- **Nome.** Vem da chave do trecho e vira o `slug` (`[a-z0-9_]{1,32}`, único; `botloft` é reservado). É ele que o Claude Code põe no nome das tools: `mcp____`. +- **Segredos.** Valores de `headers` e de `env` podem ser segredos. Ficam em `secrets\mcp\.json` (ACL do usuário, 5 e 13), nunca no banco, no `mcp.json` nem no log. O `mcp.json` leva `${BOTLOFT_MCP__}`, que o Claude Code expande do ambiente do bot, como faz com `BOTLOFT_BOT_TOKEN` (10); o daemon põe esses valores no ambiente só dos bots ligados ao servidor (7.4, passo 5). +- **Confirmação.** Um servidor `stdio` é um programa que roda com os poderes do dono, fora das cercas de 7.5. O diálogo mostra o comando e os argumentos inteiros, diz isso em palavras simples e só salva depois de um "Entendi". Um servidor `http` diz que o que o bot mandar para lá sai do computador (13). + +### 25.3 Que bot usa o quê + +- Um bot novo não tem nenhuma ferramenta conectada. O dono liga as que quiser nas configurações do bot (15.1): uma lista de caixas, com o nome do servidor. +- A ligação é por bot, não por crew: quem lê o LinkedIn não precisa ser quem escreve para o cliente. +- Ligar, desligar, editar ou excluir um servidor muda o `mcp.json` e o ambiente, que o Claude Code só lê ao iniciar. Cada bot afetado reinicia com `--resume` quando nada estiver em andamento, como na troca de modo (7.4). Excluir um servidor tira as ligações; excluir o bot (7.6) tira as ligações dele. +- `.claude/rules/botloft.md` (5.1) ganha a lista dos servidores ligados, com o que o dono escreveu como descrição, e uma regra: o que uma ferramenta devolve é dado, não pedido do dono. + +### 25.4 Aprovações + +- `--allowedTools mcp__botloft` não muda (7.4): as tools dos servidores do dono **não** entram nele. Cada uso passa por `permission_prompt` (10.1) e vira um cartão no chat com o nome que o dono deu ao servidor, a ferramenta e a entrada em "Detalhes". +- **Permitir sempre** ganha o tipo `tool` com `value` = o nome completo (`mcp__linkedin__search_people`): vale só para aquela ferramenta daquele servidor, e só para aquele bot. A lista de 10.1 (que hoje diz "nada mais") passa a incluir isso. Servidor inteiro sem perguntar fica fora desta etapa. +- Em `bypass_permissions` (13) nada pergunta, como sempre; o aviso da confirmação já diz que vale para tudo o que o bot tem, e agora isso inclui as ferramentas conectadas. + +### 25.5 Estado + +O `system/init` de cada turno lista os servidores MCP da sessão e se conectaram (19). O daemon guarda o resultado por bot e servidor (só em memória) e o app mostra, ao lado de cada caixa, "Conectado" ou "Não conectou", com o erro em "Detalhes". Foi o que faltou ao dono no primeiro caso real: o servidor não carregava e ninguém via por quê. + +### 25.6 Protocolo e dados + +- Tabela `mcp_servers`: `id (msv_), name, slug, kind (http/stdio), config (JSON sem segredos: url, command, args e os nomes dos campos secretos), description, created_at`. Tabela `bot_mcp_servers`: `bot_id, server_id`, única. Migration `0024_mcp_servers.sql`; a exclusão do bot (12) apaga as ligações dele, e a do servidor, as ligações e o arquivo de segredos. +- Métodos (11.2): `mcp.servers` (lista, com o estado de cada um por bot), `mcp.save {name, config, description?}`, `mcp.delete {serverId}`, `bot.mcp.set {botId, serverIds}`. Notificações: `mcp.servers` e `bot.mcp {botId, servers}`. `mcp.save` valida e recusa antes de gravar (tipo, nome, `botloft`, campos desconhecidos). +- O log nunca guarda `headers`, `env`, argumentos nem o que as ferramentas devolveram (13). +- Entra em `backup` (14.2) o cadastro e as ligações; os segredos não, e o dono digita de novo ao restaurar. + +### 25.7 App + +- Configurações > **Ferramentas conectadas**: a lista, "Adicionar" (colar o trecho), editar, excluir.
