The governed execution layer for enterprise AI. Nexus is built natively on the Model Context Protocol — and exposes itself as an MCP Server. Any AI agent, Claude, ChatGPT, Copilot, or your own, can trigger workflows, approve tasks, and query results through the standard protocol. No custom integration. Full audit trail.
Register any MCP server in minutes. Every tool ever built for the MCP ecosystem works with Nexus automatically — no custom connectors.
Build workflows with 17 node types — all sharing a single transaction context. True orchestration, not task chaining. Every step is part of one atomic operation.
Approval gates, escalation chains, and SLA deadlines are first-class primitives. Nexus knows when to pause, who to route to, and what to do when a deadline is missed.
Every step is event-sourced. Full input/output, token usage, cost per step, and reasoning traces — streamed live over SSE. Nothing is a black box.
Six differentiators that matter for regulated, mission-critical environments.
Every MCP server ever built works with Nexus automatically. The ecosystem builds the integrations — not us. Hundreds of connectors and growing every day, with zero hardcoded dependencies.
All nodes in a workflow share a single transaction context. This is fundamentally different from stringing tasks together — it's true orchestration with atomic consistency across every step.
Approval gates, escalation chains, and SLA deadlines are built into the core — not bolted on. Nexus knows when to pause, who to route to, and what to do when a deadline is missed.
Every step is event-sourced. You see the full input/output of every node, token usage, cost per step, and reasoning traces. Nothing is a black box — complete audit-grade transparency.
SSE-powered live monitoring. You watch workflows execute in real time — not polling for batch results. Every event is streamed the moment it happens, enabling instant intervention when needed.
No open-source license ambiguity. Purpose-built for regulated industries — AES-256-GCM encryption, RBAC, immutable audit logs, CSRF protection, and Redis rate limiting by default.
MCP-native connectors. Register any MCP server in minutes. Zero lock-in, and hundreds more joining the ecosystem every day.
Any MCP-compatible tool connects in minutes. The ecosystem builds the integrations for you.
Real-world workflows where Nexus agents execute autonomously — and improve with every transaction.
Tell Nexus what you need in plain English. The AI assistant — powered by Claude Sonnet 4 — constructs a complete workflow live on the canvas in seconds. Up to 20 tool-calling rounds per message, multi-step reasoning, and full awareness of your current canvas state.
Every execution makes Nexus smarter. Agents resolve issues autonomously and escalate to humans only when uncertain — with a full reasoning log at every step.
The Agent Node runs a full reasoning loop with Claude + MCP tools. It reads context, calls tools, evaluates results, and decides next actions — all without human intervention unless confidence drops below threshold.
Agents store and retrieve knowledge via pgvector (Aurora Serverless v2). Every resolved case enriches the knowledge base — enabling agents to recall patterns, precedents, and organizational knowledge at runtime.
Guardrails built in: max iterations, cost caps, confidence thresholds, and timeouts. When an agent is uncertain, it pauses and escalates to the right human — with full context pre-loaded in the approval form.
Every agent decision, tool call, and inference is logged with full input/output, token usage, and cost. Regulators and auditors get a complete, immutable trail of every autonomous decision ever made.
The Model Context Protocol — donated by Anthropic to the Linux Foundation in December 2025 — is rapidly becoming the industry standard for AI-to-tool communication. Nexus is the only workflow automation platform built natively on MCP from day one.
Connect any MCP-compatible server without custom connectors. No proprietary connector tax like Zapier, UiPath, or ServiceNow.
Forrester predicts 30% of enterprise vendors will launch MCP servers in 2026. Every new MCP server becomes instantly available in Nexus — zero engineering effort.
Tools are indexed automatically with full schema and documentation. Register a new MCP server and it's ready to use in workflows in minutes — no manual mapping.
The growing MCP ecosystem adds integrations without any engineering effort from us or you. The standard builds the network — Nexus benefits automatically.
Nexus isn't just a workflow platform — it's an MCP Server. Claude, ChatGPT, Copilot, Slack bots, and your own custom agents connect to Nexus directly: trigger workflows, approve tasks, query results, and manage skills — all through the standard protocol, zero custom integration code.
Competitors require 3–4 tools to match what Nexus delivers in one platform. Here's why.
