2. Architecture Constraints

This chapter outlines the constraints that shape the architecture of the MCP Documentation Server.

2.1 Technical Constraints

The system must adhere to the following technical constraints, derived directly from the PRD:

Table 1. Technical Constraints

Constraint

Description

File-System Based

The solution must not require a database. All data and state are to be managed directly on the file system.

Human-Readable Files

Source documentation files (AsciiDoc, Markdown) must remain human-readable and editable with standard text editors at all times.

Toolchain Compatibility

The system must work with existing AsciiDoc and Markdown toolchains without requiring proprietary formats or modifications.

Version Control Integration

All operations must be compatible with standard Git workflows, ensuring that file changes can be tracked, committed, and reverted.

2.2 Organizational and Process Constraints

Table 2. Organizational Constraints

Constraint

Description

Workflow Integration

The solution must integrate seamlessly into existing developer workflows without imposing significant process changes.

No External Services

The system must be self-contained and not rely on any external or third-party services for its core functionality.

Phased Development

The project will be developed in phases (Core Engine, MCP Integration, Web Interface), requiring a modular architecture that supports incremental delivery.

2.3 Conventions

To ensure consistency and quality, the following conventions will be followed:

Table 3. Architectural Conventions

Convention

Description

MCP First

The API design and implementation must be fully compliant with the Model Context Protocol (MCP) standard. This is a primary design driver.

Stateless Principle

The core server logic will be designed to be as stateless as possible, treating the file system as the single source of truth for all content and structure.

Standard Markup

The parsers will adhere to common AsciiDoc and Markdown standards. Support for non-standard or esoteric language features is a low priority.

Atomic Operations

All file modification operations must be designed to be atomic to prevent data corruption and ensure file consistency.
