Dauth Server

A comprehensive, production-ready Model Context Protocol (MCP) server designed for Business Logic, Data Processing, and Database Interactions. Built with Python and the dedalus-mcp framework, it empowers AI agents with secure, real-time tool access.

Architecture & Security

This server follows the MCP Security Model to ensure your credentials remain private:

• Zero-Trust Credentials: Your Slack tokens, Database passwords, and API keys stay on your server (in .env). They are never passed to the AI model or the Dedalus platform via curl or prompts.
• Encapsulated Execution: The AI only requests a tool action (e.g., slack_send_message). The server then executes that action locally using its own secret store.

Key Features

1. Business & Logic

• calculate_discount: Compute final prices with discounts and tax.
• validate_email: Validate email formats and domains.
• generate_invoice: Create structured invoice dictionaries.
• schedule_reminder: Mock scheduling for task reminders.

2. Data Modeling & Transformations

• analyze_csv_data: Calculate statistics (mean, max, sum) from CSV strings.
• transform_json_data: Apply transformations (uppercase, scaling) to JSON lists.
• filter_data: Filter datasets based on specific criteria.
• aggregate_data: Group and aggregate data by fields.
• merge_datasets: Join two datasets on common keys.

3. Database (Supabase / PostgreSQL)

• supabase_query: Execute safe SELECT queries with filters.
• supabase_insert: Insert records into tables.
• supabase_update: Update existing records.
• postgres_execute: Execute raw SQL queries (for complex operations).

4. External Integrations

• slack: Send messages and list channels efficiently.
• search: Web search via Brave API.
• weather: Real-time weather data from OpenWeather.

Quick Start

Follow these steps to get your MCP server up and running in minutes:

1. Installation

Ensure you have Python 3.13+ installed, then clone the repo and install dependencies:

git clone https://github.com/johnoseni1/MCP-Dauth-Server.git
cd MCP-Dauth-Server
pip install -r requirements.txt

2. Configuration

Copy the template and fill in your actual credentials:

cp .env.example .env
# Open .env and add your Slack/DB/Brave keys

Environment Variable Reference

[!IMPORTANT] Slack Setup: Ensure your bot has chat:write, channels:read, and groups:read scopes. You must invite the bot to a channel (e.g., /invite @MyBot) before it can post messages.

3. Database Setup (Optional)

If you are using the PostgreSQL/Supabase features, run the schema initializer:

python db_setup.py

4. Running the Server

python main.py

• Local: Runs via Stdio for direct LLM integration (like Claude Desktop).
• Cloud (Railway/Render): Automatically switches to HTTP/SSE if a PORT environment variable is detected.

Testing

Local API Verification

python test_client.py

Interactive Console

Use the Interactive Client to test any tool manually without writing code:

python interactive_client.py
