⚙️ MCP Architecture & Protocol Implementation

The core architecture of ExMCP Test Server is built upon solid foundational layers:

PhxJsonRpc: This library forms the backbone of the RPC layer, providing robust mechanisms to handle JSON-RPC 2.0 requests and responses.
ExJsonSchema: Utilized for schema-driven validation of incoming and outgoing data, ensuring that all packets are compliant with defined schemas.
Jason: For efficient JSON encoding and decoding, this library enables seamless data exchange between the server and clients.

This architecture ensures high performance and scalability, making ExMCP Test Server a reliable choice for integrating complex AI workflows.

🚀 Getting Started with Installation

To begin using ExMCP Test Server locally, follow these steps:

Ensure you have Elixir 1.14 or higher installed.
Install the necessary dependencies by running:
```
mix deps.get
```
To run the server in a development environment, execute:
```
mix run --no-halt
```

For production deployments, it's recommended to generate a release and integrate with appropriate configuration:

mix release

Add this to your claude_desktop_config.json or equivalent file for deployment:

{
  "mcpServers": {
    "ex-mcp-test": {
      "command": "path/to/your/realease/bin/my_app",
      "args": [
        "start"
      ]
    }
  }
}

These steps ensure a smooth start-up and integration process, making it easier to deploy the server in real-world scenarios.

💡 Key Use Cases in AI Workflows

ExMCP Test Server can be applied in various AI workflows, enhancing efficiency and flexibility. Here are two realistic examples:

Content Generation Workflow:
- An AI content generation system can use ExMCP Test Server to interact with multiple data sources and tools. Initial prompts are sent using the prompts/list method, which returns a list of available prompts. These prompts are then used by the AI model to generate text, adhering to specified guidelines.
Chat Assistant Integration:
- A chat assistant can leverage ExMCP Test Server to access integrated tools and resources. For instance, users can request information using voice commands (prompts), and the server processes these requests through defined MCP methods like prompts/list and tools/call. This integration ensures real-time and contextually relevant responses.

These use cases highlight how ExMCP Test Server enhances AI applications by providing a standardized protocol for interactions between different components.
