## Introduction / Main Floor: Nexus MCP: A Unified Gateway for Local Agent Workflows

Nexus MCP is a single MCP gateway designed for local agent workflows. It routes calls to multiple backend services via a unified interface, including the Mnemo memory system, Thrift toolset, Router decision routing, and Governor operation governance, enabling automated lifecycle management of agent interactions.

## Background: Complexity Challenges of Agent Workflows

With the deepening application of Large Language Models (LLMs), a single model call can no longer meet the needs of complex tasks. Modern AI systems usually consist of multiple specialized components working together: memory modules maintain context, toolkits provide external capabilities, routers handle task distribution, and governors monitor operational status. However, these components often expose independent APIs, requiring developers to manually coordinate call sequences, record interaction logs, and manage error recovery, leading to a sharp increase in code complexity.

## Design Philosophy of Nexus MCP

Nexus MCP adopts a 'single gateway' architecture, encapsulating multiple backend services into a unified MCP (Model Context Protocol) interface. The core idea of this design is: expose a minimal interaction interface externally, and automatically handle complex coordination logic internally. Developers only need to interact with Nexus without worrying about the details of calling multiple underlying services.

Nexus only exposes one MCP tool `nexus`, and accesses backend capabilities through different namespace actions (namespace.subaction). This design maintains the simplicity of the protocol while providing full functional coverage.

## Core Features and Namespace Architecture

Nexus divides backend services into five main namespaces:

## 1. Nexus Core Namespace

Provides interaction lifecycle management and system diagnosis functions, including `start_interaction` (initiate interaction), `finish_interaction` (complete interaction), `status` (status query), `doctor` (health check), etc. This is the entry point for using Nexus.

## 2. Router Decision Routing

Responsible for task routing, workflow classification, and decision validation, including actions like `route`, `classify`, `validate_decision`, `list_workflows`, etc., to help agents choose the optimal execution path.

## 3. Governor Operation Governance

Provides comprehensive operation monitoring and governance functions, including `start_run`, `record_event`, `record_tool_call`, `check_budget`, `finish_run`, etc., to ensure agent operations are traceable, auditable, and controlled.

## 4. Thrift Toolset

Provides development tools such as file operations, code search, task classification, cost reporting, etc., like `find_files`, `grep_text`, `rank_files`, `file_window`, `classify_task`, etc.
