   AI-Powered Backend for Your Knowledge Base
==================================================

Welcome to the Notemd MCP Server! This project provides a powerful, standalone backend server that exposes the core AI-powered text processing and knowledge management functionalities of the Notemd Obsidian Plugin.

English | 简体中文

Built with Python and FastAPI, this server allows you to offload heavy computational tasks from the client and provides a robust API to interact with your knowledge base programmatically.

Features

- AI-Powered Content Enrichment: Automatically processes Markdown content to identify key concepts and create `[[wiki-links]]`, building a deeply interconnected knowledge graph.

- Automated Documentation Generation: Generates comprehensive, structured documentation from a single title or keyword, optionally using web research for context.

- Integrated Web Research & Summarization: Performs web searches using Tavily or DuckDuckGo and uses an LLM to provide concise summaries on any topic.

- Diagram Workflows (Canonical + Compatibility Alias): Supports `generate_diagram` as the canonical flow plus `generate_experimental_diagram` as a legacy compatibility alias aligned with modern NotEMD command surfaces.

- Translation & Extraction Utilities: Adds first-class translation, concept extraction, and verbatim original-text extraction operations for automation pipelines.

- Knowledge Graph Integrity: Includes endpoints to automatically update or remove backlinks when files are renamed or deleted, preventing broken links.

- Syntax Correction: Provides a utility to batch-fix common Mermaid.js and LaTeX syntax errors often found in LLM-generated content.

- Highly Configurable: All major features, API keys, file paths, and model parameters are easily managed in a central `config.py` file.

- Multi-LLM Support: Compatible with any OpenAI-compliant API, including local models via LMStudio and Ollama, and cloud providers like DeepSeek, Anthropic, Google, and more.

- Interactive API Docs: Comes with automatically generated, interactive API documentation via Swagger UI.

How It Works

The server is built on a simple and logical architecture:

- `main.py` (API Layer): Defines all API endpoints using the FastAPI framework. It handles incoming requests, validates data using Pydantic, and calls the appropriate functions from the core logic layer.

- `notemd_core.py` (Logic Layer): The engine of the application. It contains all the business logic for interacting with LLMs, processing text, performing web searches, and managing files within your knowledge base.

- `config.py` (User-Defined Space): The central configuration hub. This is where you define your file paths, API keys, and tune the behavior of the server to fit your needs.

- `cli.js` (MCP Bridge): A Node.js-based command-line interface that acts as a bridge to the Python server. It uses the `@modelcontextprotocol/sdk` to create a server that can be called by other tools. It starts the FastAPI server and then communicates with it via HTTP requests.

Getting Started

Follow these steps to get the Notemd MCP server up and running on your local machine.

Prerequisites

- For Python execution: Python 3.8+ and `pip` or `uv`.

- For NPX execution: Node.js and `npx`.

Installation & Running

Choose the method that best fits your workflow.

Method 1: Using `npx` (Recommended for Quick Start)

This is the simplest way to start the server. `npx` will temporarily download and run the package. This method now supports stdio mode, meaning you will see the FastAPI server logs directly in your terminal.

# This single command will download the package and start the server.
npx notemd-mcp-server

Method 2: Local Installation with `uv` or `pip`

This method is for users who want to clone the repository and manage the files locally.

1. Clone the repository:

git clone https://github.com/your-repo/notemd-mcp.git
    cd notemd-mcp

2. Install dependencies:

uv venv
        uv pip install -r requirements.txt

python -m venv .venv
        # Activate the environment (e.g., source .venv/bin/activate)
        pip install -r requirements.txt

3. Run the server:

uvicorn main:app --reload

Method 3: MCP Configuration

To integrate Notemd MCP with your Mission Control Platform (MCP) setup, add the following to the `mcpServers` object in your `settings.json` file:

{
   "mcpServers": {
     "notemd-mcp": {
       "description": "Notemd MCP Server - AI-powered text processing and knowledge management
 for your Markdown files.",
       "command": "npx",
       "args": [
         "-y",
         "notemd-mcp-server"
       ],
       "env": {
         "OPENAI_API_KEY": "your_openai_api_key_here",
         "DEEPSEEK_API_KEY": "your_deepseek_api_key_here"
       }
     }
   }
 }

Usage

The best way to explore and interact with the API is through the automatically generated documentation.

- Navigate to `http://127.0.0.1:8000/docs` in your web browser.

You will see a complete, interactive Swagger UI where you can view details for each endpoint, see request models, and even send test requests directly from your browser.

API Endpoints

Configuration

All configuration is handled in the `config.py` file. Here you can set API keys, file paths, and other settings.

Core Settings

The `notemd_core.set_settings` function in `main.py` initializes the core functionalities of the server using the following parameters, primarily sourced from `config.py`:

• `DEFAULT_PROVIDERS`: A list of dictionaries, each defining an LLM provider with its `name`, `apiKey`, `baseUrl`, `model`, `temperature`, and optional `apiVersion` (for Azure OpenAI).
• `ACTIVE_PROVIDER`: The name of the LLM provider to be used by default for all operations.
• `CHUNK_WORD_COUNT`: The maximum number of words per chunk when processing content for wiki-linking.
• `MAX_TOKENS`: The maximum number of tokens allowed for LLM interactions.
• `ENABLE_DUPLICATE_DETECTION`: Boolean to enable/disable duplicate concept detection during wiki-linking.

File Paths Configuration

These settings define the directory structure for your knowledge base and logs:

• `VAULT_ROOT`: The absolute path to your Obsidian vault or the root directory of your Markdown files.

Release (npm + PyPI)

Use this one-line command to bump one shared version and publish both npm and PyPI in sync:

npm run release:sync-publish -- 0.6.1

Dry-run (no publish):

npm run release:sync-publish -- 0.6.1 --dry-run

Notes:

• The command updates npm version (`package.json` + `package-lock.json`), and syncs Python/server versions in `setup.py`, `main.py`, and `cli.js`.
• Make sure npm auth is ready (`npm login` or `NPM_TOKEN`) and PyPI auth is ready (`~/.pypirc` or `TWINE_USERNAME` + `TWINE_PASSWORD`).
• It builds Python artifacts and runs `twine check` before upload.
