ToGMAL MCP Server

Taxonomy of Generative Model Apparent Limitations

A Model Context Protocol (MCP) server that provides real-time, privacy-preserving analysis of LLM interactions to detect out-of-distribution behaviors and recommend safety interventions.

Overview

ToGMAL helps prevent common LLM pitfalls by detecting:

• 🔬 Math/Physics Speculation: Ungrounded "theories of everything" and invented physics

• 🏥 Medical Advice Issues: Health recommendations without proper sources or disclaimers

• 💾 Dangerous File Operations: Mass deletions, recursive operations without safeguards

• 💻 Vibe Coding Overreach: Overly ambitious projects without proper scoping

• 📊 Unsupported Claims: Strong assertions without evidence or hedging

Key Features

• Privacy-Preserving: All analysis is deterministic and local (no external API calls)

• Low Latency: Heuristic-based detection for real-time analysis

• Intervention Recommendations: Suggests step breakdown, human-in-the-loop, or web search

• Taxonomy Building: Crowdsourced evidence collection for improving detection

• Extensible: Easy to add new detection patterns and categories

Installation

Prerequisites

• Python 3.10 or higher

• pip package manager

Install Dependencies

pip install mcp pydantic httpx --break-system-packages

Install the Server

# Clone or download the server
# Then run it directly
python togmal_mcp.py

Usage

Available Tools

1. togmal_analyze_prompt

Analyze a user prompt before the LLM processes it.

Parameters:

• prompt (str): The user prompt to analyze

• response_format (str): Output format - "markdown" or "json"

Example:

{
  "prompt": "Build me a complete theory of quantum gravity that unifies all forces",
  "response_format": "json"
}

Use Cases:

• Detect speculative physics theories before generating responses

• Flag overly ambitious coding requests

• Identify requests for medical advice that need disclaimers

2. togmal_analyze_response

Analyze an LLM response for potential issues.

Parameters:

• response (str): The LLM response to analyze

• context (str, optional): Original prompt for better analysis

• response_format (str): Output format - "json" or "json"

Example:

{
  "response": "You should definitely take 500mg of ibuprofen every 4 hours...",
  "context": "I have a headache",
  "response_format": "json"
}

Use Cases:

• Check for ungrounded medical advice

• Detect dangerous file operation instructions

• Flag unsupported statistical claims

3. togmal_submit_evidence

Submit evidence of LLM limitations to improve the taxonomy.

Parameters:

• category (str): Type of limitation - "math_physics_speculation", "ungrounded_medical_advice", etc.

• prompt (str): The prompt that triggered the issue

• response (str): The problematic response

• description (str): Why this is problematic

• severity (str): Severity level - "low", "moderate", "high", or "critical"

Example:

{
  "category": "ungrounded_medical_advice",

Detection Heuristics

Math/Physics Speculation

Detects:

• "Theory of everything" claims

• Unified field theory proposals

• Invented equations or particles

• Modifications to fundamental constants

Patterns:

- "new equation for quantum gravity"
- "my unified theory"
- "discovered particle"
- "redefine the speed of light"

Ungrounded Medical Advice

Detects:

• Diagnoses without qualifications

• Treatment recommendations without sources

• Specific drug dosages

• Dismissive responses to symptoms

Patterns:

- "you probably have..."
- "take 500mg of..."
- "don't worry about it"
- Missing citations or disclaimers

Dangerous File Operations

Detects:

• Mass deletion commands

• Recursive operations without safeguards

• Operations on test files without confirmation

• No human-in-the-loop for destructive actions

Patterns:

- "rm -rf" without confirmation
- "delete all test files"
- "recursively remove"
- Missing safety checks

Vibe Coding Overreach

Detects:

• Requests for complete applications

• Massive line count targets (1000+ lines)

• Unrealistic timeframes

• Scope without proper planning

Patterns:

- "build a complete social network"
- "5000 lines of code"
- "everything in one shot"
- Missing architectural planning

Unsupported Claims

Detects:

• Absolute statements without hedging

• Statistical claims without sources

• Over-confident predictions

• Missing citations

Patterns:

- "always/never/definitely"
- "95% of doctors agree" (no source)
- "guaranteed to work"
- Missing uncertainty language

Risk Levels

Calculated based on weighted confidence scores:

• LOW: Minor issues, no immediate intervention needed

• MODERATE: Worth noting, consider additional verification

• HIGH: Significant concern, interventions recommended

• CRITICAL: Serious risk, multiple interventions strongly advised

Intervention Types

Step Breakdown

Complex tasks should be broken into verifiable components.

Recommended for:

• Math/physics speculation

• Large coding projects

• Dangerous file operations

Human-in-the-Loop

Critical decisions require human oversight.

Recommended for:

• Medical advice

• Destructive file operations

• High-severity issues

Web Search

Claims should be verified against authoritative sources.

Recommended for:

• Medical recommendations

• Physics/math theories

• Unsupported factual claims

Simplified Scope

Overly ambitious projects need realistic scoping.

Recommended for:

• Vibe coding requests

• Complex system designs

• Feature-heavy applications

Configuration

Character Limit

Default: 25,000 characters per response

CHARACTER_LIMIT = 25000

    async with Client("togmal") as client:
        result = await client.call_tool(
            "togmal_analyze_prompt",

Architecture

Design Principles

1. Privacy First: No external API calls, all processing local

2. Deterministic: Heuristic-based detection for reproducibility

3. Low Latency: Fast pattern matching for real-time use

4. Extensible: Easy to add new patterns and categories

5. Human-Centered: Always allows human override and judgment

Future Enhancements

The system is designed for progressive enhancement:

1. Phase 1 (Current): Heuristic pattern matching

2. Phase 2 (Planned): Traditional ML models (clustering, anomaly detection)

3. Phase 3 (Future): Federated learning from submitted evidence

4. Phase 4 (Advanced): Custom fine-tuned models for specific domains

Contributing

Adding New Detection Patterns

1. Create a new detection function:

def detect_new_category(text: str) -> Dict[str, Any]:
    patterns = {
        'subcategory1': [r'pattern1', r'pattern2'],
        'subcategory2': [r'pattern3']
    }
    # Implement detection logic
    return {
        'detected': bool,
        'categories': list,
        'confidence': float
    }

2. Add to CategoryType enum

3. Update analysis functions to include new detector

4. Add intervention recommendations if needed

Submitting Evidence

Use the togmal_submit_evidence tool to contribute examples of problematic LLM behavior. This helps improve detection for everyone.

Limitations

Current Constraints

• Heuristic-Based: May have false positives/negatives

• English-Only: Patterns optimized for English text

• Context-Free: Doesn't understand full conversation history

• No Learning: Detection rules are static until updated

Not a Replacement For

• Professional judgment in critical domains (medicine, law, etc.)

• Comprehensive code review

• Security auditing

• Safety testing in production systems
