🎯 What Is This?

Q1-Reviewer-MCP is a Model Context Protocol (MCP) server that turns Claude into a merciless academic peer reviewer. It reads your .docx manuscript, applies a battle-tested Q1 Red Flag Matrix, and produces a professionally formatted .docx decision letter — complete with color-coded severity ratings.

Think of it as having a permanently angry Reviewer #2 living inside your AI assistant, catching the exact issues that get manuscripts rejected from Nature, Cell, Plant Physiology, and other Q1 journals.

The Problem It Solves

Academic authors routinely receive "Major Revision" or "Reject" decisions due to preventable issues:

• 🔴 Overclaiming in the Discussion ("We proved that...")
• 🔴 Causal language without mechanistic evidence
• 🟠 Weak knowledge-gap framing in the Introduction
• 🟠 Insufficient biological replicates (n < 3)
• 🟡 Missing statistical test justification
• 🟡 No limitations paragraph

These issues are invisible to the author but predictable to an experienced reviewer. Q1-Reviewer catches them before submission.

✨ Features

<table> <tr> <td width="50%">

🔬 Q1 Red Flag Matrix

Embedded review criteria covering:

• Overclaiming detection — flags "prove", "perfectly", "definitively" in biological contexts
• Causal language audit — catches "X causes Y" when only correlation data exists
• Introduction analysis — detects missing knowledge gap statements
• Methodology audit — flags n<3 replicates, missing normality tests, absent controls
• Discussion audit — catches new data, excessive speculation, missing limitations
• Results verification — ensures claims reference figures/tables

</td> <td width="50%">

📄 Professional Output

Decision letters that look like real journal reviews:

• Color-coded severity — 🔴 Critical (red), 🟠 Major (orange), 🟢 Positive (green)
• Structured format — Editor Decision → Concerns → Revisions → Strengths
• Times New Roman, justified — academic standard formatting
• Issue-level guidance — THE FLAW → THE Q1 STANDARD → THE DIRECTION
• Saved as .docx — ready to share with co-authors

</td> </tr> <tr> <td>

🧠 3-Tier Section Detection

Handles any manuscript format:

• Tier 1: Word Heading styles (most reliable)
• Tier 2: Bold/uppercase keyword matching (no styles? no problem)
• Tier 3: Full-text fallback (unstructured? we'll still review it)

</td> <td>

🌍 Smart Language Detection

Designed for scientific manuscripts:

• Multi-section sampling for accuracy
• Filters Latin taxonomic names (Arabidopsis thaliana, E. coli)
• Won't mistake in vitro or et al. for non-English text

🏗️ Architecture

Q1-Reviewer-MCP follows the Tool-as-Data-Fetcher pattern — the MCP server is purely a filesystem operator. All analytical intelligence lives in the host LLM (Claude), guided by the Q1 Red Flag Matrix embedded in tool descriptions.

└──────────────────────────────────────────────────────────────┘

Why this design?

• 🧠 All intelligence upgrades automatically — when Claude improves, reviews improve
• 💰 Zero server-side LLM costs — no API calls from the server
• 🧪 Easy to test — server only does file I/O
• 🔒 Secure — no ports, no HTTP, no authentication (stdio only)

📦 Installation

Prerequisites

• Python 3.10+
• Claude Desktop or Cursor (any MCP-compatible host)

Install from PyPI

pip install q1-reviewer-mcp

Install from Source

git clone https://github.com/ZaEyAsa/Q1-reviewer-mcp.git
cd Q1-reviewer-mcp
pip install -e .

---

⚙️ Configuration

Claude Desktop

Add to your Claude Desktop config file:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "q1-reviewer": {
      "command": "python",
      "args": ["-m", "q1_reviewer.server"]
    }
  }
}

Note: If python isn't in your PATH, use the full path (e.g., "C:\\Python313\\python.exe" on Windows).

Cursor

Add the same configuration in Cursor Settings → MCP Servers.

Verify Installation

After restarting Claude Desktop, you should see three tools available:

• parse_manuscript_sections — reads your manuscript
• generate_docx_report — writes the review report
• compare_revisions — compares V1 review with V2 manuscript (Phase 3)

---

🚀 Usage

Quick Start

1. Open Claude Desktop
2. Provide your manuscript path:

Please review my manuscript at:
C:/Users/me/Desktop/my_paper_v1.docx

Save the review report to the same directory.

3. Claude will:
   • 📖 Read and parse your manuscript sections
   • 🔬 Apply the Q1 Red Flag Matrix
   • 📝 Generate a detailed critique
   • 💾 Save a formatted .docx decision letter

What You'll Get

A professional .docx report containing:

Section	Description
Editor Decision	Overall verdict (Accept / Minor Revision / Major Revision / Reject)
Critical Concerns	🔴 Issues that would likely cause immediate rejection
Major Concerns	🟠 Significant issues requiring substantial revision
Minor Concerns	Issues that should be addressed but aren't dealbreakers
Recommended Revisions	Numbered action items for the author
Positive Aspects	🟢 Strengths of the manuscript (yes, we're fair too)

Example Output

Each issue follows the structured format:

issue_1: Pervasive Overclaiming

THE FLAW: The manuscript uses "proved" and "definitively demonstrated" in the Discussion, which are absolute claims inappropriate for biological research.

THE Q1 STANDARD: Q1 journals expect hedged language that reflects the inherent uncertainty of experimental biology. Only mathematical proofs allow "prove."

THE DIRECTION: Replace absolute claims with "suggest", "indicate", or "support the hypothesis that."

🔍 Q1 Red Flag Matrix

The review engine applies these rule categories:

<details> <summary><strong>🔴 Overclaiming Rules</strong> (click to expand)</summary>

• Flags absolute language: "prove", "perfect", "completely", "definitively", "undoubtedly"
• Context-aware: accepts in mathematical/structural biology proofs
• Flags causal language ("X causes Y") when only correlation data is presented
• Suggests appropriate alternatives: "indicate", "suggest", "demonstrate" </details>

<details> <summary><strong>📝 Introduction Audit Rules</strong></summary>

• Detects missing knowledge gap statements
• Flags overpromising scope (claims vs. actual methodology)
• Checks for the critical sentence: "However, [specific gap] remains unknown" </details>

<details> <summary><strong>🔬 Methodology Audit Rules</strong></summary>

• Statistical test justification required
• Normality test reference for parametric tests
• Biological replicates: n ≥ 3 or power analysis
• Negative controls in functional assays
• Units on all numerical measurements </details>

<details> <summary><strong>💬 Discussion Audit Rules</strong></summary>

• New data in Discussion (must appear in Results first)
• Speculation depth limit (max 2 inferential steps)
• Mandatory limitations paragraph
• Data-claim alignment check </details>
