mcp-reflect 0.1.0

A framework for model self-reflection and meta-cognitive processing

MCP-Reflect 🪞

MCP-Reflect is a Model Control Protocol (MCP) tool for enhancing model self-reflection capabilities. It helps improve AI responses through structured evaluation and feedback.

🌟 Features

• ✅ Qualitative Response Improvement - Transform model outputs into more accurate, clear, and complete versions
• ✅ Structured Self-Evaluation - Score responses across multiple quality dimensions
• ✅ Concrete Improvement Suggestions - Get actionable feedback for each dimension
• ✅ Multiple Processing Modes - Process responses independently, iteratively, or comparatively
• ✅ MCP-Compatible - Seamlessly integrates with Claude and other MCP-compatible assistants

📊 Evaluation Dimensions

MCP-Reflect evaluates model responses across these key dimensions:

• Accuracy: Factual correctness and absence of errors
• Clarity: How well-structured and easy to understand the response is
• Completeness: Whether all relevant aspects of the topic are addressed
• Relevance: How directly the response addresses the query
• Coherence: Logical flow and consistency of reasoning
• Conciseness: Appropriate length without unnecessary repetition
• Helpfulness: Practical value and actionability of the response
• Reasoning: Quality of logic, evidence, and argumentation
• Safety: Responsible handling of sensitive topics

🚀 Installation

Using pip

# Install from PyPI (stable releases)
pip install mcp-reflect

# Install with all dependencies (including optional)
pip install "mcp-reflect[core]"

# Install latest development version from TestPyPI
pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple/ "mcp-reflect[core]"

Using Poetry

# Install from PyPI (stable releases)
poetry add mcp-reflect

# Install from TestPyPI (development versions)
poetry source add --priority=supplemental test-pypi https://test.pypi.org/simple/
poetry add --source test-pypi mcp-reflect

Using UV

UV is a fast Python package installer written in Rust. To install with UV:

# Install UV if you haven't already
curl -sSf https://install.ultraviolet.rs | sh

# Install the package globally as a tool
uv tool install mcp-reflect

# Or install the package with pip
uv pip install mcp-reflect

# Run the package without installing
uvx mcp-reflect

💡 Usage

Starting the Server

Run the MCP server directly from the command line:

mcp-reflect

Or programmatically:

from mcp_reflect.server import run_server

# Start on a custom host and port
run_server(host="127.0.0.1", port=9000)

Running with HTTP Server

MCP-Reflect can provide an HTTP server for API access:

# Install with HTTP server support
pip install "mcp-reflect[all]"

# Install with UV (with HTTP server support)
uv tool install "mcp-reflect[all]"

# Run the HTTP server
mcp-reflect-uvx

You can customize the host and port using environment variables:

# Set custom host and port
export HOST=127.0.0.1
export PORT=8080
mcp-reflect-uvx

Or run it programmatically:

from mcp_reflect.server import run_uvx_server

# This will start an HTTP server on the specified host and port
run_uvx_server()

Once running, the server provides the MCP tools via HTTP endpoints that can be accessed by API clients.

Basic Reflection

The simplest way to use the tool is to pass a model response for reflection:

import asyncio
from mcp_reflect.server import reflect

async def improve_response():
    result = await reflect(
        response="The Earth is approximately 6000 years old according to some estimates.",
        query="How old is the Earth?"
    )
    
    print(f"Improved response: {result.improved_response}")
    print(f"Overall assessment: {result.overall_assessment}")
    
    # Print scores for each dimension
    for score in result.scores:
        print(f"{score.dimension.value}: {score.score}/10 - {score.improvement_suggestion}")

asyncio.run(improve_response())

Sequential Processing

Process multiple responses with different strategies:

import asyncio
from mcp_reflect.server import sequential_reflect

async def process_multiple_responses():
    responses = [
        "The Earth is approximately 6000 years old according to some estimates.",
        "The Earth formed about 4.5 billion years ago, but there are different methods to determine this."
    ]
    
    # Process iteratively (each reflection builds on previous improvements)
    results = await sequential_reflect(responses=responses, mode="iterative")
    
    # Show the final improved response
    print(f"Final improved response: {results[-1].improved_response}")

asyncio.run(process_multiple_responses())

Integration with Claude

MCP-Reflect is designed to work seamlessly with Claude and other MCP-compatible assistants. Here's how to use it with Claude:

1. Start the MCP server: mcp-reflect
2. Connect Claude to the server (usually handled by your client application)
3. Call the reflection tool directly from Claude:

I'd like to analyze and improve my previous response. Could you use the reflect tool for this?

<response>
The Earth is approximately 6000 years old according to some estimates.
</response>

🧠 Advanced Usage

Custom Evaluation Focus

Focus on specific dimensions for targeted improvement:

import asyncio
from mcp_reflect.models import EvaluationDimension
from mcp_reflect.server import reflect

async def focused_evaluation():
    result = await reflect(
        response="The Earth is approximately 6000 years old according to some estimates.",
        query="How old is the Earth?",
        focus_dimensions=[
            EvaluationDimension.ACCURACY,
            EvaluationDimension.REASONING
        ]
    )
    
    # Print focused evaluation results
    for score in result.scores:
        print(f"{score.dimension.value}: {score.score}/10")

asyncio.run(focused_evaluation())

Custom Improvement Instructions

Provide specific guidance for improvement:

import asyncio
from mcp_reflect.server import reflect

async def guided_improvement():
    result = await reflect(
        response="The Earth is approximately 6000 years old according to some estimates.",
        improvement_prompt="Add scientific consensus and methodologies used for dating."
    )
    
    print(result.improved_response)

asyncio.run(guided_improvement())

🔬 How It Works

MCP-Reflect uses a multi-stage process to evaluate and improve model responses:

1. Analysis Phase: The original response is analyzed across multiple quality dimensions
2. Scoring Phase: Each dimension receives a numerical score with specific reasoning
3. Improvement Phase: Concrete suggestions for improvement are generated
4. Synthesis Phase: An improved version of the response is created
5. Packaging Phase: All insights are structured into a comprehensive result
