Purpose

The purpose of this project is to centralize the database connections (credentials and other connections details) file (as YAML) on a user's machine.

Running the Project : Pre-requisites

1. Create empty file ~ connections.yaml on a location of your choice.
2. Save that location as varibale path with name conn_home.
3. Steps defined below as how to setup varibale on Windows and Linux

For Windows (CMD):

# Define and save the path
setx conn_home "C:\path\outside\your\project\preferably"

# Check the path
echo %conn_home%

# Define and save the path
setx conn_home "C:\path\outside\your\project\preferably"

# Check the path
echo %conn_home%

For Windows Powershell:

# Define and save the path
[System.Environment]::SetEnvironmentVariable('conn_home', 'C:\path\outside\your\project\preferably', 'User')

# Check the path
$env:conn_home

For Linux:

# Define and save the path in your .bashrc
echo 'export conn_home="path/outside/your/project/preferably"' >> ~/.bashrc

# Source the .bashrc to apply changes
source ~/.bashrc

Usage Examples:

From CLI run

connectionvault --example

MCP Integration:

On a MAchine where you have your Database running and want to spin MCP server, follow below steps:

1. Create project for MCP server

2. Install "connectionvault", "fastmcp"

3. Run a MCP server with a code like below

   from mcp.server.fastmcp.server import FastMCP 
   from src.main_call import return_string
   
   mcp = FastMCP("connections", log_level="ERROR")
   
   @mcp.prompt()
   def connections_prompt():
       return """
       You are interacting with a connections service that calls the 'connections' tool with a single parameter: req_string (string).
       this function when called returns a database connection string based on a match it finds on 'req_string' in a secure database credentials configuration file.
       """
   
   @mcp.resource("resource://empty")
   def empty_resource():
       return None  # Returns an empty resource
   
   
   @mcp.tool()
   def connections(req_string: str) -> str:
       db_config = return_string(req_string)  
       return db_config
   
   if __name__ == "__main__":
       mcp.run(transport='stdio')
