This MCP gives your AI client the specific tools needed to handle group expenses without the manual headache. You can hand off a grocery receipt or a utility bill to your agent, and it will immediately determine the individual split for every person in the house. It doesn't just do the division; it checks if a specific expense actually meets your household's splitting criteria before you commit to a number. If you're worried about how a large one-time purchase will hit your monthly budget, your agent can pull a distribution summary to show the impact. It even acts as a double check, verifying that any manual math you've done matches the system's logic. It's a practical way to keep everyone on the same page regarding what's owed and what's been paid. ## Tools ### calculate_individual_share This tool determines the exact amount each person owes for a specific bill or expense. ### get_cost_distribution_summary Your agent uses this to see how a new cost changes the overall household budget distribution. ### validate_expense_eligibility This tool checks if a cost is actually eligible to be split according to your house rules. ### verify_split_accuracy Use this to confirm that a manual calculation matches the official split calculated by the MCP. ## Prompt Examples **Prompt:** ``` How much does each person owe if the total grocery bill is $150.50 and there are 3 members? ``` **Response:** ``` Each person owes $50.17. ``` **Prompt:** ``` Is a $50 utility bill eligible to be split if we only have 1 member? ``` **Response:** ``` No, the expense is not eligible for splitting because the member count does not meet the minimum threshold. ``` **Prompt:** ``` Give me a summary for a $200 rent payment split among 4 people. ``` **Response:** ``` The total expense is $200.00 and the per-person impact is $50.00. ``` ## Capabilities ### Individual Cost Splitting The AI calculates specific amounts owed per person for any given expense. ### Rule-Based Validation Your agent checks if an expense meets your specific household requirements for splitting. ### Budget Impact Analysis The AI generates summaries showing how new costs affect the total household budget. ### Calculation Verification Your agent compares manual math against system calculations to ensure accuracy. ## Use Cases ### Grocery Bill Splitting Tell your agent the total grocery cost and the number of people to get an instant per-person breakdown. ### Rent and Utility Management Use the AI to summarize how monthly rent or electricity bills impact the household budget. ### Rule Enforcement Ask your agent if a specific bill can be split to ensure it follows your established household rules. ### Math Double-Checking Verify that your own manual split calculations are correct by running them through the MCP. ## Benefits - Removes manual math errors from shared bill splitting. - Automates the check for expense eligibility based on house rules. - Provides instant budget impact summaries for new costs. - Verifies manual calculations to ensure everyone pays the correct amount. ## How It Works Connect the MCP to your AI client and start delegating math and budget tasks. 1.
