Africa's Talking Airtime MCP

This project implements a Model Context Protocol (MCP) server that enables seamless interaction with the Africa's Talking API for airtime-related operations. It provides a suite of tools for checking account balances, sending airtime, viewing transaction history, and summarizing top-up data. The server uses an SQLite database for persistent storage and includes logic for formatting phone numbers for various African countries.

Key Features

• Check Balance: Instantly retrieve the current airtime balance of your Africa's Talking account.

• Send Airtime: Load airtime to any phone number in supported countries.

• Transaction Logging: Automatically save every transaction to a local SQLite database.

• Transaction History: View a list of the most recent top-up transactions.

• Summarize Top-ups: Calculate the total amount of the last 'n' top-ups.

• Count Top-ups: Count the number of transactions for a specific phone number.

• Phone Number Formatting: Automatically formats phone numbers to include the correct country code.

Tool Reference

The MCP server exposes the following tools for managing airtime:

check_balance

• Description: Retrieves the current airtime balance from your Africa's Talking account.

• Usage: check_balance()

• Returns: A string displaying the account balance (e.g., "Account Balance: KES 1234.00") or an error message.

load_airtime

• Description: Sends a specified amount of airtime to a phone number and records the transaction.

• Arguments:

  • amount (float): The amount of airtime to send.

  • currency_code (str): The currency code (e.g., "KES", "UGX").

• Usage: load_airtime(phone_number="0712345678", amount=100.0, currency_code="KES")

• Returns: A confirmation message upon success or an error message.

get_last_topups

• Description: Fetches the last N airtime top-up transactions from the database.

• Arguments:

  • limit (int, optional): The number of transactions to retrieve. Defaults to 3.

• Usage: get_last_topups(limit=5)

• Returns: A formatted string listing the recent transactions.

sum_last_n_topups

• Description: Calculates the sum of the last N top-ups.

• Arguments:

  • n (int, optional): The number of transactions to sum. Defaults to 3.

• Usage: sum_last_n_topups(n=5)

• Returns: A string with the total sum, or an error if transactions have different currencies.

count_topups_by_number

• Description: Counts the number of successful top-ups to a specific phone number.

• Arguments:

  • phone_number (str): The phone number to query.

• Usage: count_topups_by_number(phone_number="0712345678")

• Returns: The total count of top-ups for the given number.

Example Prompts

Here are some example prompts you can use to interact with the MCP server:

• Check Balance:

  • "What is my Africa's Talking account balance?"

  • "Check my airtime balance."

• Send Airtime:

  • "Send 100 KES airtime to 0712345678."

  • "Top up my phone +254712345678 with 50 bob."

  • "Load 200 UGX to 0755123456."

• View Recent Top-ups:

  • "Show me the last 3 airtime transactions."

  • "List my 5 most recent top-ups."

• Sum Recent Top-ups:

  • "What is the total of my last 3 top-ups?"

  • "How much have I spent in my last 5 transactions?"

• Count Top-ups:

  • "How many times have I topped up 0712345678?"

  • "Count the top-ups to +254712345678."

Important Notes

• Funding: Ensure your Africa's Talking account has sufficient funds to send airtime.

• Phone Number Formatting: Phone numbers are automatically formatted based on the country environment variable.

• Database: The SQLite database (airtime_transactions.db) is automatically created in the project directory.

• Supported Models: This MCP server works best with models that support tool calling, such as Claude 3.7 Sonnet or GPT-4.1 Nano.
