Iconsult MCP

Architecture consulting for multi-agent systems, grounded in the textbook.

Iconsult is an MCP server that reviews your multi-agent architecture against a knowledge graph of 141 concepts and 462 relationships extracted from Agentic Architectural Patterns for Building Multi-Agent Systems (Arsanjani & Bustos, Packt 2026). Every recommendation comes with chapter numbers, page references, and concrete code-level changes — not abstract advice.

See It In Action

We pointed Iconsult at OpenAI's Financial Research Agent — a 5-stage multi-agent pipeline from their Agents SDK — and asked it to find architectural gaps.

The agent's current architecture

The Financial Research Agent uses a 5-stage sequential pipeline orchestrated by FinancialResearchManager. Search is the only concurrent stage — everything else runs in sequence, and the verifier is a terminal dead end:

What Iconsult found

Solid foundation, but Iconsult's knowledge graph traversal uncovered 4 critical gaps:

Adding a feedback loop, quality gate, shared memory, and retry logic:

How it got there

The consultation followed Iconsult's guided workflow:

1. Read the codebase — Fetched all source files from manager.py, agents/*.py. Identified the orchestrator pattern in FinancialResearchManager, the .as_tool() composition, the silent except Exception: return None in search, and the terminal verifier.

2. Match concepts — match_concepts embedded the project description and deterministically ranked the most relevant patterns: Orchestrator, Planner-Worker, Agent Delegates to Agent, Tool Use, and Supervisor.

2b. Plan — plan_consultation assessed complexity and generated an adaptive plan — how many concepts to traverse, whether to use subagents, and which critique steps to include.

3. Traverse the graph — get_subgraph explored each seed concept's neighborhood. The requires edges revealed that the Supervisor pattern requires Auto-Healing — which was entirely missing. The complements edges surfaced Hybrid Planner+Scorer as a natural addition. log_pattern_assessment recorded each finding for deterministic scoring.

4. Retrieve book passages — ask_book scoped to the discovered concepts returned exact citations: chapter numbers, page ranges, and quotes grounding each recommendation.

5. Score + stress test + synthesize — score_architecture computed the maturity scorecard from logged assessments. generate_failure_scenarios produced concrete cascading failure traces for each gap — showing exactly what breaks and how failures propagate. Then generated the interactive before/after architecture diagram with specific file-level changes, prerequisite checks, and conflict analysis. All recommended patterns are complementary — no conflicts detected.

What It Does

Point it at a codebase (or describe your architecture), and it runs a structured consultation: matching concepts, traversing the knowledge graph for prerequisites and conflicts, scoring maturity against a 6-level model, and generating an interactive HTML review with before/after architecture diagrams.

The Knowledge Graph

141 concepts  ·  786 sections  ·  462 relationships  ·  1,248 concept-section mappings

Relationship types span uses, extends, alternative_to, component_of, requires, enables, complements, specializes, precedes, and conflicts_with — discovered through five extraction phases including cross-chapter semantic analysis.

Setup

Prerequisites

• Python 3.10+
• A MotherDuck account (free tier works)
• OpenAI API key (for embeddings used by ask_book)
• Claude Code with the visual-explainer skill installed (required for architecture diagram rendering — see below)

Database Access

The knowledge graph is hosted on MotherDuck and shared publicly. The server automatically detects whether you own the database or need to attach the public share — no extra configuration needed. Just provide your MotherDuck token and it works.

Install visual-explainer (Claude Code skill)

Iconsult renders architecture diagrams as interactive HTML pages using the visual-explainer skill. Install it once:

git clone https://github.com/nicobailon/visual-explainer.git ~/.claude/skills/visual-explainer
mkdir -p ~/.claude/commands
cp ~/.claude/skills/visual-explainer/prompts/*.md ~/.claude/commands/

This gives Claude Code the /generate-web-diagram command used during consultations. Diagrams are written to ~/.agent/diagrams/ and opened in your browser automatically.

Install

pip install git+https://github.com/marcus-waldman/Iconsult_mcp.git

For development:

git clone https://github.com/marcus-waldman/Iconsult_mcp.git
cd Iconsult_mcp
pip install -e .

Environment Variables

export MOTHERDUCK_TOKEN="your-token"    # Required — database
export OPENAI_API_KEY="sk-..."          # Required — embeddings for ask_book

MCP Configuration

Add to your Claude Desktop config (claude_desktop_config.json) or Claude Code settings:

{
  "mcpServers": {
    "iconsult": {
      "command": "iconsult-mcp",
      "env": {
        "MOTHERDUCK_TOKEN": "your-token",
        "OPENAI_API_KEY": "sk-..."
      }
    }
  }
}
