## MCP tools (4)

### `school_district` (~91 tokens)

Look up the actual school district for any US address. Uses Census Bureau boundary data — NOT zip codes. Zip codes often map to the wrong district (e.g. 617 School Rd has a Nazareth zip but is actually Pen Argyl SD). This tool gets it right.

Input parameters:

- `address` (string, required): Full street address, e.g. "123 Main St, Nazareth, PA 18064"

### `eit_rate` (~137 tokens)

Look up Pennsylvania Earned Income Tax (EIT) rates by municipality, county, or school district. Returns municipal rate, school district rate, total combined rate, non-resident rate, and Local Services Tax. Data source: PA DCED Act 32.

Input parameters:

- `county` (string): County name, e.g. "Northampton" or "LEHIGH"
- `municipality` (string): Municipality name, e.g. "Plainfield Township" or "PLAINFIELD TWP"
- `schoolDistrict` (string): School district name, e.g. "Pen Argyl Area" or "NAZARETH AREA S D"

### `affordability` (~367 tokens)

Calculate monthly mortgage payment (PITI), debt-to-income ratios, PMI, and whether a home purchase is comfortable, a stretch, or risky. Supports 15 or 30-year terms. Pass a 2-letter state code (e.g. 'PA', 'TX') for accurate state income tax in take-home pay — covers all 50 states. Defaults to 3% if omitted.

Input parameters:

- `annualIncome` (number, required): Gross annual household income in dollars
- `annualInsurance` (number): Known annual homeowner's insurance in dollars. If omitted, estimated at 0.35% of home price.
- `annualPropertyTax` (number): Known annual property tax in dollars. If omitted, estimated at 1.2% of home price.
- `downPaymentPercent` (number, required): Down payment as a percentage of home price, e.g. 20
- `eitRate` (number): Local earned income tax rate as a percentage (e.g. 1.5). Affects take-home pay calculation. Use eit_rate tool to look this up for PA.
- `homePrice` (number, required): Home purchase price in dollars
- `interestRate` (number, required): Mortgage interest rate as a percentage, e.g. 6.5
- `loanTermYears` (number): Loan term in years. Default: 30. Use 15 for a 15-year mortgage.

### `full_analysis` (~221 tokens)

Run a complete property analysis: school district lookup, PA EIT rates, and affordability calculation — all in one call. Provide an address and financial details to get a comprehensive buy/pass assessment. State is auto-detected from the address. May take 3-5 seconds due to geocoding API calls.

Input parameters:

- `annualIncome` (number, required): Gross annual household income
- `annualInsurance` (number): Known annual insurance
