# Plotune Nexus Documentation

Documentation



Reference documentation for engineers evaluating or operating Plotune Nexus: what the appliance actually does, what it doesn't yet do, and how to verify either.

[SecuritySecurity & Trust ModelHow device ownership, key custody, and access boundaries work: what stays on the device, what a compromised session can and cannot do, and what is still being hardened.7 min read](https://www.plotune.net/docs/nexus/security-model)[CompatibilityHardware & Protocol CompatibilityWhich CAN, UART, XCP, and DoIP hardware families run natively on Nexus today, which need a container, and which are not yet supported, stated without inflating the claim.8 min read](https://www.plotune.net/docs/nexus/hardware-compatibility)[API ReferenceMCP Tools & API ReferenceThe actual MCP tool surface an agent calls: real tool names, read-only resources, authentication, and the client setup commands for Claude Code, Codex, Cursor, VS Code, and n8n.9 min read](https://www.plotune.net/docs/nexus/mcp-api)[ArchitectureSystem ArchitectureThe three-plane model behind Nexus: what runs on the device, what runs in Plotune’s cloud, and the exact boundary between them, including where the design is still hardening.7 min read](https://www.plotune.net/docs/nexus/architecture)[DeploymentData Handling & Deployment ModelWhere recorded data lands first, how it leaves the device, the bring-your-own-cloud model, and the checklist for deploying into a closed network with no internet access.6 min read](https://www.plotune.net/docs/nexus/data-handling)[ProtocolsProtocol Notes: CAN, UDS, DoIP, XCPTransport-level detail for the four protocols Nexus speaks today: addressing modes, discovery mechanics, and exactly what is production-qualified versus implemented-but-unqualified.8 min read](https://www.plotune.net/docs/nexus/protocols)[OnboardingQuick StartFrom power-on to your first bounded hardware workflow: network setup, owner bootstrap, connecting an MCP client, and three runnable simulator-based examples that need no hardware yet.6 min read](https://www.plotune.net/docs/nexus/quick-start)
