Handlers typically receive a `uri` argument. +- **Prompts**: Reusable, parameterised prompt templates the client can surface (e.g. in Claude Desktop). Register with `registerPrompt()` or equivalent. +- **Transport**: stdio for local clients (e.g. Claude Desktop); Streamable HTTP is preferred for remote (Cursor, cloud). Legacy HTTP/SSE is for backward compatibility. + +The Node/TypeScript SDK may expose `tool()` / `resource()` or `registerTool()` / `registerResource()`; the official SDK has changed over time. Always verify against the current [MCP docs](https://modelcontextprotocol.io) or Context7. + +### Connecting with stdio + +For local clients, create a stdio transport and pass it to your server’s connect method. The exact API varies by SDK version (e.g. constructor vs factory). See the official MCP documentation or query Context7 for "MCP stdio server" for the current pattern. + +Keep server logic (tools + resources) independent of transport so you can plug in stdio or HTTP in the entrypoint. + +### Remote (Streamable HTTP) + +For Cursor, cloud, or other remote clients, use **Streamable HTTP** (single MCP HTTP endpoint per current spec).

Same for resources — include a `uri` in the handler when the API provides it.

+```typescript +// Tests depend on each other +test('creates user', () => { /* ... */ }) +test('updates same user', () => { /* depends on previous test */ }) +``` + +### ✅ CORRECT: Independent Tests +```typescript +// Each test sets up its own data +test('creates user', () => { + const user = createTestUser() + // Test logic +}) + +test('updates user', () => { + const user = createTestUser() + //

Visão Geral + +MultiplAI v2 evolui de um pipeline fixo Claude-only para um **sistema de orquestração de N assinaturas AI** que aloca dinamicamente subscriptions (API keys, CLI logins, flat-rate plans) entre roles, projetos e tarefas — tudo gerenciado por uma instância Linux com Slack como interface de comando. + +### 1.1 Princípio Central + +Assinaturas são **recursos computacionais**, não ferramentas individuais.

O sistema nunca falha — espera. +6. **Observable**: toda alocação, transição, e resultado é logado e visível. +7. **Deterministic allocation**: score explícito + `FOR UPDATE SKIP LOCKED`. Empates por `sub.id`. +8. **Explicit retries**: novas tentativas persistidas no banco com `retry_after`. Nunca recursão. Nunca `setTimeout`. +9. **Strong isolation**: git worktree efêmera, subprocess com limites de recurso, variáveis CI, detecção de TTY hang, buffer overflow protection, cleanup em `finally`. +10. **Event-driven queue**: LISTEN/NOTIFY com reconnect automático + catch-up forçado. +11. **No in-memory truth**: estado operacional sempre no banco. Caches locais invalidados via NOTIFY. +12. **Crash-safe**: reconciliation job no startup recupera zombies, orphaned worktrees, e retries pendentes. +13. **Tool-aware allocation**: subscriptions declaram comandos nativos, MCP servers, ECC profiles, e skills. O allocator pontua subscriptions com tools relevantes mais alto. +14. **ECC-enhanced workspaces**: cada projeto tem ECC instalado com profile adequado. Skills, agents, hooks, e continuous learning do ECC são camadas operacionais dos workspaces. ECC AgentShield (102 regras de segurança) é camada 2 no review pipeline. + +--- + +## 2.

Security + +1. **API keys never in DB** — env vars only. +2. **CLI sessions isolated** — each runs in own worktree with CI env vars. +3. **CLI TTY protection** — stall detection (60s), prompt detection (regex), buffer cap (10MB), graceful kill (SIGTERM → 5s → SIGKILL). +4. **Blocked paths enforced** — 3-layer PathGuard. Violations fail immediately. +5. **Secret detection** — multiline-aware regex on added content (not just diff headers). Covers API keys, private keys, AWS keys, Slack tokens. Blocks to `BLOCKED_SECURITY` with human override via Slack. +6. **Webhook signatures** — GitHub and Slack verified. +7. **Allocation audit** — every allocation logged with score breakdown in JSONB. +8. **No cross-project contamination** — worktrees, paths, standards per-project. +9. **No shared state** — worktrees ephemeral, cleaned in `finally` + reconciliation. +10. **Atomic pool operations** — `FOR UPDATE SKIP LOCKED` prevents double allocation. +11. **No shell injection** — all git operations via `execFileSync` with array args. No string interpolation in commands. +12. **No in-memory truth** — operational state in DB. Local caches invalidated via NOTIFY. +13. **Crash recovery** — reconciliation job on startup resets zombies, prunes orphans, re-enqueues retries. +14. **ECC AgentShield** — 102 security rules scan every diff as review layer 2. Catches prompt injection, config drift, guardrail gaps, and unsafe defaults that regex-based lint would miss. +15. **ECC fail-open** — if the ECC instance is down, the pipeline continues without layer 2 (logs warning). Security scan is additive, never blocks the pipeline due to infrastructure failure. + +--- + +## 21. Future Extensions + +1. **Local fine-tuned model** — Ollama subscription with LUXST-trained reviewer (when M5 Pro arrives). Complements ECC: fine-tune encodes static patterns, ECC captures dynamic patterns. +2. **Auto-scaling suggestions** — detect queue bottlenecks, suggest adding subscriptions. +3. **Subscription performance comparison** — same task, different providers. +4. **Multi-repo PRs** — tasks spanning multiple repos. +5. **OpenClaw bridge** — WhatsApp/Telegram alongside Slack. +6. **AST-based lint** — replace regex lint with tree-sitter for lower false positive rate. +7. **Cost optimization engine** — automatically route low-complexity tasks to cheaper subs. +8. **ECC Tools GitHub App** — integrate ECC Tools App for PR-triggered config audits and auto-analysis on push events. +9. **Cortex integration** — Rust agent runtime (github.com/aiconnai/cortex) as compute worker for heavy data processing tasks (lead enrichment, batch scoring on 223M+ records). + +--- + +> **MultiplAI v2** — N assinaturas.
