SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Nexus removes the need to build separate APIs, CLIs, and MCP servers for the same workflow, while also reducing boilerplate, startup issues, and production configuration drift.

Core Features & Use Cases

  • Multi-channel deployment: Register a workflow once and expose it through API, CLI, and MCP.
  • Production guardrails: Use unified sessions, auth, rate limiting, health checks, monitoring, and security defaults.
  • Common use cases: Workflow-backed SaaS APIs, AI agent tools, DataFlow CRUD endpoints, and production deployment patterns.

Quick Start

Ask for a minimal Nexus app that registers one workflow and exposes it through API, CLI, and MCP.

FAQPage Schema
How do I expose a single workflow through API, CLI, and MCP simultaneously?▼

Multi-channel deployment exposes a single registered workflow through API, CLI, and MCP simultaneously. You register the workflow once using the .build() method, and the platform handles channel-specific execution without requiring separate server setups.

What is the best way to avoid boilerplate when building workflow-backed SaaS APIs?▼

Using a unified deployment platform removes the boilerplate of building separate APIs, CLIs, and MCP servers. It provides built-in session handling, authentication via the NexusAuthPlugin, and production guardrails like rate limiting and health checks.

Does DataFlow CRUD work with Nexus workflow registration?▼

DataFlow integrates with workflow registration by setting auto_discovery=False and configuring explicit connections. This enables DataFlow-backed CRUD endpoints to function correctly within the deployed API and CLI channels.

Why does my Nexus workflow deployment fail during startup?▼

Production deployment troubleshooting often points to missing explicit connections or incorrect runtime setup. Reliable operation requires using the AsyncLocalRuntime, the NexusAuthPlugin, and ensuring workflows are registered via the .build() method.

Can I use Nexus for AI agent tools and production monitoring?▼

Nexus supports AI agent tools by exposing workflows through MCP, and includes built-in production monitoring, security defaults, and unified sessions. These guardrails ensure stable operation for workflow-backed applications.
