Skincare-MCP

Overview

Skincare-MCP is a Model Context Protocol (MCP) server that provides AI-based skin analysis based on a selfie image URL. It accepts a URL pointing to a user-provided selfie, analyzes the image through two stages of processing, and returns comprehensive skin status, management recommendations, and therapy guidance. The server can be integrated with any MCP-compatible client—such as Claude Desktop App, Continue, Cline, and others—to enable real-time skincare diagnostics and personalized advice.

Features

• Analyze basic skin status from a selfie (e.g., care-needed regions, estimated skin age, skin point score).

• Determine detailed skin type attributes (Dry, Oily, Pigmented, etc.) and generate a type code.

• Recommend tailored management methods (e.g., hydration routines, pore tightening toners).

• Provide detailed skin context and quantitative point scores for Pigmented, Pores, Redness, Sebum, Trouble, Wrinkle.

• Offer therapy guidance, including advantages, cautions, detailed procedure, and expected effect.

• Return a “recommend therapy” field (e.g., “Aqua Peeling”) based on the user’s skin profile.

How It Works

Poke-MCP is built using the Model Context Protocol, which enables AI applications to access external tools and data sources in a standardized way. The server:

1. Connects to the skincareAPI to fetch skincare data

2. Exposes several tools through the MCP interface

3. Processes requests from MCP clients

4. Returns formatted skincare information

MCP Tools

The Skincare-MCP server exposes the following primary tool:

• get-skin-analysis:

  • Description: Given a selfie image URL, returns a JSON object containing all available skin analysis fields (both basic status and detailed management/therapy information).

  • Input Parameters:

    • image_url (string): Publicly accessible URL of the user’s selfie image.

  • Output: JSON containing fields (listed in “Provided Fields” below).

Provided Fields

The server returns all of the following fields (no separate “analysis_1” vs. “analysis_2” nesting is exposed to the client; they’re merged in output).

1. need_therapy

   • Array of face regions requiring care or therapy (e.g., ["right cheek", "jaw"]).

2. skin_age

   • Integer representing the estimated skin age.

3. skin_point

   • max_score (number): Maximum possible score (e.g., 10).

   • current_score (number): User’s current skin point score.

4. skin_type (boolean flags)

   • Dry

   • Non_Pigmented

   • Oily

   • Pigmented

   • Resistant

   • Sensitive

   • Tight

   • Wrinkle

5. skin_type_analysis.type_code

   • A string code representing the combination of True/False flags (e.g., “OSRT”).

6. manage_methods.recommend_methods

   • Array of strings suggesting skin management routines (e.g., hydration, pore-tightening toner, double cleansing at night, sebum-controlling cleanser, weekly sebum care pack).

7. skin_detail_analysis.skin_detail_context

   • Array of descriptive keywords summarizing detailed skin condition (e.g., ["elastic skin texture", "oil and pore management needed"]).

8. skin_detail_analysis.skin_detail_points

   • Pigmented (number)

   • Pores (number)

   • Redness (number)

   • Sebum (number)

   • Trouble (number)

   • Wrinkle (number)

   • max_score (number)

9. therapy.all_datas

   • advantage (string): Description of therapy’s main advantages.

   • caution (array of strings): List of post-treatment precautions.

   • detail (string): Detailed explanation of the procedure and mechanism.

   • effect (string): Expected outcome/effect on the skin.

10. therapy.recommend_therapy

    • A single string with the recommended therapy name (e.g., “Aqua Peeling”).

Architecture

Skincare-MCP is built using:

• TypeScript (Node.js runtime)

• @modelcontextprotocol/sdk (MCP TypeScript SDK for tool registration and message handling)

• Zod (for schema validation of incoming parameters)

• Express.js (or similar HTTP server framework) to handle the HTTP POST endpoint and route requests internally

• Internal ML Model (Python ONNX or TensorFlow backend) to perform image-based skin analysis

• Sharp or Jimp (Node.js image processing) to fetch and pre-process images from URLs before feeding them to the ML model

Manual Installation

After starting, the server listens on a default port (e.g., 3000) and can be invoked by an MCP client at:

Usage

With Claude Desktop App

1. Download and install Claude Desktop App.

2. Open Claude Desktop settings, then go to Developer settings.

3. Edit your configuration file (e.g., config.json) to include:

   { "mcpServers": { "skincare": { "command": "node path/to/skincare-mcp/build/index.js" } } }

4. Restart Claude Desktop.

5. You will now see a “get-skin-analysis” tool under the “skincare” server when interacting with Claude.

Example Queries

Once connected, you can ask your MCP-capable client (e.g., Claude Desktop) to run commands like:

• “Analyze my skin: get-skin-analysis image_url=https://example.com/selfie.jpg”

• “What management methods should I follow for my skin?” (the client can automatically call get-skin-analysis behind the scenes)

• “Recommend a therapy based on my skin condition”

Adding New Features

To extend Skincare-MCP with additional tools or analyses:

1. Define new Zod schemas in src/types.ts for any additional input parameters or output fields.

2. Create helper functions in src/utils/ (e.g., data fetchers, new model inferences).

3. Register a new tool in src/tools.ts using:

   server.tool( "new-skin-tool", "Description of this new tool’s functionality.", { /* input parameter schema via Zod */ }, async (params) => { // Tool logic: fetch/process image, call model, return JSON } );

4. Update to import and include the new tool.

5. Write unit/integration tests under tests/ to validate new functionality.

6. Rebuild and restart the server to make the new tool available to MCP clients.
