Phase 1 - Foundation

Goal: Lay out the base foundational capabilities required to build a modular monolith: Docker Compose, single-user auth, Prisma configuration, CI.

Status: ✅ Complete

TLDR

Phase 1 established the working mechanics of the backend service within the monorepo. It isn't the complex multi-tenant engine yet, but it features robust database connection, logging, error handling, and linting.

What was built

Docker Infrastructure

  • Added docker-compose.yml defining the postgres and redis instances required for local development.

NestJS Backend Structure

  • Initialized Prisma (schema.prisma) inside the api app.
  • Setup HealthModule linking up NestJS terminus health checks for both Postgres and Redis.
  • Setup global configuration validation (ConfigModule) utilizing class-validator. The server will fail to start if DATABASE_URL or REDIS_URL are omitted.

Cross-Cutting Concerns

  • Setup global error filters and standardization for API responses.
  • Setup interceptors and correlation IDs to trace operations across boundaries.
  • Laid in basic single-user scaffolding as a placeholder before moving to multi-tenancy.

CI & Tooling

  • Finalized integration of strict TypeScript checking.
  • Centralized eslint.config.mjs workspace checks to eliminate module resolution and formatting headaches.

Next Steps

Now that the foundation is stable, Phase 2 will focus heavily on the Connector Registry: creating the database schema to store details of remote MCP servers and exposing CRUD APIs to configure and discover them.
