Local-First Deployment
Relevant source files
The following files were used as context for generating this wiki page:
The Local-First Deployment model of the Nexus Orchestrator establishes an autonomous infrastructure daemon designed to operate as a background orchestration layer. It functions as a "nervous system" for AI development, primarily managing environments and connectivity directly on local or private infrastructure rather than relying on centralized cloud abstractions. This approach prioritizes low-latency agent-to-infrastructure communication and maintains high data sovereignty by keeping the state and execution local to the developer's environment.

Core Architecture and Pillars
The local-first deployment is built upon four foundational pillars that enable an autonomous infrastructure daemon to bridge the gap between AI agents and their operating environments.
| Pillar | Functionality |
|---|---|
| Connectivity | MCP-based protocol for agent-infrastructure communication |
| Orchestration | LangGraph-powered workflow management |
| Context | Persistent state and AGENTS.md management |
| Governance | OPA + Zero Trust security for non-human identities |

Infrastructure Orchestration Flow
The following diagram illustrates how the Nexus Orchestrator functions as a local daemon, mediating between AI agents and local/remote environments through the MCP protocol.
The Nexus Orchestrator serves as the central hub, utilizing the Model Context Protocol (MCP) to allow agents to interact with environments, SSH connectivity, and persistent state files locally.

Environment Management
Local-first deployment focuses on the autonomous management of execution environments. This includes the lifecycle of containers and SSH connections required for agent tasks.
Connectivity Layer
The system uses an MCP-based protocol to facilitate communication. This allows agents to request infrastructure changes or access resources without manual configuration of SSH keys or environment variables for every session.
Context and State
The orchestrator maintains a local "Context Layer" that includes:
- Persistent State: Tracking the current status of the infrastructure.
- Agent Registry: A local
AGENTS.mdfile that tracks known AI agents and their associated trust levels.
| Field | Description |
|---|---|
| Agent ID | Unique identifier for the AI agent |
| Description | Purpose or role of the agent |
| Trust Level | Security tier assigned via Governance layer |

Governance and Security
Despite being a local-first system, the orchestrator implements "Zero Trust" security principles tailored for non-human identities (AI agents).
- OPA Governance: Uses Open Policy Agent (OPA) to define and enforce fine-grained access control over what infrastructure an agent can modify.
- Non-Human Identities: Every agent interacting with the local daemon is treated as a unique identity requiring specific trust levels.

Security Sequence
This diagram shows the verification process when an agent attempts to access local infrastructure.
The Nexus daemon intercepts agent requests and validates them against the local OPA governance policy before interacting with the underlying environment.

Conclusion
The Local-First Deployment of Nexus Orchestrator transforms the developer's machine into an autonomous "nervous system" for AI agents. By synthesizing MCP, LangGraph, and Zero Trust security, it provides a robust, local-first bridge between high-level agent logic and low-level infrastructure execution.
