Decibel Architect is an MCP server designed to provide persistent architectural memory and creative autonomy for AI-assisted development.

Decibel Architect

MCP server providing persistent architectural memory and creative autonomy for AI-assisted development

Vision

Decibel Architect gives AI coding agents creative autonomy - enabling innovative freedom within architectural boundaries while maintaining system coherence through explicit contracts.

The Creative Autonomy Model

When Code (CC) has clear architectural guardrails:

  • ✅ Ships creative solutions immediately (80% of proposals)
  • ✅ Flags architectural concerns for review (20% of proposals)
  • ✅ Innovates within boundaries (fast + safe)
  • ✅ Prevents technical debt (no architectural violations)

Without guardrails: Fast but chaotic (constant rework)
With over-constraints: Slow and stifled (creativity squashed)
With Decibel Architect: Creative autonomy (fast, innovative, coherent)

The Nintendo Story

Gunpei Yokoi - maintenance engineer at Nintendo who invented the Game Boy while having creative autonomy within boundaries. His managers gave him:

  • ✅ Freedom to tinker and invent
  • ✅ Clear constraints (manufacturing, strategy)
  • ✅ Recognition when inventions aligned
  • ❌ No micromanagement

Result: One of the most impactful engineers in gaming history.

Decibel Architect does the same for AI agents.

Status

🚧 In Development - Specification complete, MCP server implementation in progress

  • Core concept and Creative Autonomy model
  • Complete specification
  • Working example: Senken architecture
  • MCP server implementation (Phase 1)
  • Flow validation system (Phase 2)
  • Search and context tools (Phase 3)

The Problem

When working with AI coding agents:

  • ✅ Tactical execution is excellent (Code can implement features rapidly)
  • ❌ Strategic coherence breaks down (agents "fix" problems by changing core architecture)
  • ❌ Architectural decisions are lost between sessions
  • ❌ Service boundaries are violated without awareness

Result: Fast iteration but architectural drift and technical debt accumulation.

The Solution

Persistent architectural documentation that AI agents can:

  1. Query before proposing changes - "Does this cross a service boundary?"
  2. Validate against during implementation - "Does this fit the order execution flow?"
  3. Update when making decisions - "Log why we rejected polling mechanisms"
  4. Reference during code review - "Show me all decisions about position tracking"

For Decibel Suite

Pairs with Decibel Designer:

  • Designer: Design system memory and guardrails
  • Architect: Code architecture memory and guardrails

Both about the same thing: Structure that enables creative autonomy.
