Prerequisites

• Python 3.12 or higher

• uv (Python package manager and project manager)

Installation

1. Ensure you have Python 3.12+ installed.

2. Install uv if not already installed:

   pip install uv

3. Clone or download this project to your local machine.

4. Navigate to the project directory:

   cd "path/to/mcp server"

5. Create a virtual environment and install dependencies:

   uv sync

Running the Server

To run the MCP server in development mode:

uv run mcp dev mcp_server.py

The server runs on stdio transport, suitable for MCP clients.

Testing the Functionality

Test client is provided in mcp_client.py to verify the server works.

To test:

1. In one terminal, start the server:

   uv run python mcp_server.py

2. In another terminal, run the test client:

   uv run mcp_client.py

This will connect to the server and list the available tools, printing them to the console.

For more advanced testing, you can modify mcp_client.py to call specific tools, read resources, or get prompts.

Example: To read a document content, you could add code like:

# Inside the async main function
doc_content = await client.call_tool("read_doc_contents", {"doc_id": "deposition.md"})
print(doc_content)

Project Structure

• mcp_server.py: The main MCP server implementation.

• mcp_client.py: A test client for interacting with the server.

• pyproject.toml: Project configuration and dependencies.

Notes

• The server uses an in-memory dictionary for documents. Changes are not persisted.

• Ensure the virtual environment is activated when running Python commands.
