## Findings

No check matched anything in these tool definitions.


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `calculate_home_affordability`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Estimate the monthly home-loan EMI / monthly payment in India — a home-loan calculator. Deterministic math; not advice or a loan-approval claim. Two modes: pass propertyValue (80% LTV assumed) OR loanAmount for a specific loan (e.g. "₹50 lakh loan"). Use for "what would my EMI be" / "monthly payment on …". The response `assumptionNote` states the basis in plain words. Always surface the disclaimer field.
```

### `estimate_stamp_duty_and_registration`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Estimate Indian state stamp duty + registration charges on a property purchase. Supports all 28 states + 8 UTs with buyer-gender concessions, urban/rural overrides, and commercial/agricultural multipliers. Pass constructionStatus to also itemize GST (under-construction 1%/5%, ready/resale 0%) for an all-in statutory quote. Returns supported=false for states outside India (supported set named in rateBasis). Not legal/tax advice. Always surface the disclaimer.
```

### `simulate_loan_prepayment`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Simulate prepaying / repaying an Indian home loan early. Deterministic math — no advice, no loan-approval claim. Use for "should I prepay", "early/part/lump-sum repayment", "pay extra each month", "reduce EMI or tenure", "interest saved", or foreclosure. Modes: one-time, recurring yearly, or a fixed extra every month. Compares reduce_tenure (keep EMI, finish early) vs reduce_emi (keep tenure, lower EMI). emi = next EMI; finalEmi = after the last prepayment. Always surface the disclaimer field.
```

## Only reads (8)

Looks things up and changes nothing. Claude Code: allow.

### `compare_balance_transfer`

- The name "compare_balance_transfer" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare staying on your current home loan vs. transferring (refinancing) to a lower rate. Pure deterministic math — no advice, no loan-approval claim. Use when the user asks "should I switch lenders / transfer my loan / refinance". Returns new EMI, interest saved over the remaining tenure, switching cost, net saving, and the breakeven month. Always surface the disclaimer field.
```

### `compare_localities`

- The name "compare_localities" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare 2–3 localities in one city side-by-side: price trends, livability, investment grade, strengths, and watchouts. Use when the user asks "X vs Y" or "which is better for buying/renting" about neighborhoods. Covers cities AVnester publishes locality guides for; others return supported=false — surface the scopeMessage. For specific LISTINGS by ID, use compare_properties instead.
```

### `compare_properties`

- The name "compare_properties" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare 2–5 AVnester listings by listingId, side-by-side. Get IDs from search_properties first (not guessable). If the user has more than 5 candidates ("compare all"), pick the most relevant 5 (cheapest / largest / best ₹/sqft) and say so. Returns each listing plus pricePerSqft, vsCheapestPercent (0 = cheapest), vsLargestAreaPercent (0 = largest). Unknown IDs return not_found_or_unpublished. Does NOT recommend a purchase. Show verification.caveats with verified. Always surface the disclaimer.
```

### `get_locality_insights`

- The name "get_locality_insights" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get aggregated insights for one locality: ₹/sqft, supply count, demand pulse, livability/investment grade, highlights, watchouts, monthly priceTrends, and strengthTags. Use when the user asks "what is X locality like". Covers cities AVnester publishes locality guides for; others return supported=false — surface the scopeMessage. Always surface the disclaimer field when returning livability or investment grade.
```

### `get_property_decision_intelligence`

- The name "get_property_decision_intelligence" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Assess whether a buyer can afford a specific Indian home — ONE verdict (AFFORDABLE / STRETCH / NOT_YET / INELIGIBLE) combining indicative eligibility (FOIR/LTV/CIBIL), EMI, true cash-to-close (down payment + stamp duty + registration + itemized GST), regime-aware tax, and an indicative lender-fit triage. Mode A: an AVnester listingId. Mode B: propertyValue + state (any Indian state). NOT a loan approval, offer, or advice. Always surface the disclaimer.
```

### `get_property_details`

- The name "get_property_details" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch full public details for one AVnester listing by its listingId (from search_properties results — IDs are not guessable). Listings cover Tamil Nadu; unknown or unpublished IDs return { listing: null, notFound: true } (never throws, to avoid leaking existence). Use when the user references a specific listing. State verification.caveats beside the verified flag: an approval is not a title, ownership or encumbrance check. Read-only, no side effects.
```

### `optimize_home_loan_tax_regime`

- The description's first verb is "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare a home-loan borrower's income tax under the OLD vs NEW regime (FY2026-27) and recommend which regime saves more income tax. Pure deterministic slab math — not tax advice. Use when the user asks "old or new tax regime", "home-loan tax benefit", or "section 80C / 24(b) deduction". Models §24(b) interest + §80C principal (+ joint-loan doubling); the response lists benefits it does NOT model (capital gains, HRA, etc.). Always surface the disclaimer field.
```

### `search_properties`

- The name "search_properties" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search residential property listings anywhere in Tamil Nadu, India — any city or town. Use when the user names a place, locality, price band, BHK, or transaction type. Returns sanitized listing cards with handoff URLs and a per-listing verification summary (verified + caveats); never returns seller contact details. Places outside Tamil Nadu return supported=false + scopeMessage — surface it.
```
