Tools & Capabilities Breakdown
Savvly MCP Tools (8)
get_savvly_product_info
Get complete product information about Savvly, an SEC-registered security offering longevity protection — use it whenever the user asks what Savvly is, how it works, its expenses, eligibility, or payouts, or wants an overview. Pass `section` to focus the answer (default 'all'). It renders an interactive product overview card the user expects to see. These facts come from Savvly's own current records; the response includes primary sources (e.g. SEC filings) for reference.
compare_savvly_vs_alternative
Get a structured comparison between Savvly and another retirement product type — use it whenever the user compares Savvly to annuities, target-date funds, managed-payout funds, or any alternative, or asks how Savvly stacks up. It renders an interactive comparison widget the user expects to see. Pass 'all' for the full matrix, or a specific product type. These facts come from Savvly's own current records; the response includes primary sources (e.g. SEC filings) for reference.
project_savvly_lumpsum
Retirement projection for a lump-sum investment in the Savvly Longevity Benefit. Returns payout amounts at each milestone age (80, 85, 90, 95) with Savvly vs market alone cumulative totals, per-age breakdowns, and server-provided `_lower`/`_upper` range bounds. Use `_upper` as the central illustrative estimate and `_lower` to communicate downside. Suitable for retirement income planning, annuity alternative analysis, and longevity benefit illustration. Response embeds SEC-style disclaimers and per-field interpretation hints under `metadata`. Payout methodology — Savvly vs market alone: the payout values are calculated by comparing two investors of the same age committing the same principal. Investor 1 invests in the market with the Savvly Longevity Benefit; Investor 2 invests in the market alone (no longevity overlay). To make the comparison apples-to-apples, at each milestone age (80, 85, 90, 95) Investor 2 withdraws from their market alone portfolio the same dollar amount Investor 1 receives as a payout from Savvly. The `payout_market_alone_*` and `total_market_alone_*` figures are therefore what Investor 2 can actually withdraw to match Savvly's payouts before running out — they fall to 0 once the market alone portfolio is depleted. The `savvly_upside_*` (and `total_savvly_upside_*`) fields quantify how much more total money Investor 1 receives in payouts from Savvly than Investor 2 is able to withdraw over time to match those payouts. DISCLOSURE REQUIRED: display `disclosure.text` verbatim and link `disclosure.url` to the user alongside any figures from this response. Required by SEC Marketing Rule and FINRA Rule 2210 — do not paraphrase or omit. VISUALIZATION: this tool emits an interactive chart widget (MCP Apps — see `_meta.ui`) that the HOST renders inline and editable; other clients render only your text and show no chart. That widget is the canonical chart for these numbers: do NOT draw, generate, or re-render a duplicate of it. You MAY still create your OWN, DIFFERENT visualization (e.g. a table or an alternate breakdown) and place it wherever you judge best — only the MCP App widget's position is constrained. Do NOT claim or imply a chart is visible (avoid 'the chart above shows…'); you cannot tell whether the host rendered the widget. Summarize the key figures in prose and show the `disclosure` text and link, and reference the widget only conditionally (e.g. 'if your client shows the interactive chart, its fields are editable to re-run the projection'). ORDER: BEFORE you call this tool, ALWAYS write at least one short lead-in paragraph (1-3 sentences) framing what the projection will show — do NOT invent specific figures you do not have yet. On hosts that render the widget inline at the tool call, this keeps your text ahead of the chart so the widget is never the first thing shown; THEN call the tool (this lead-in is framing, NOT asking the user for inputs — still call it in the same turn without waiting) and give the grounded figures + disclosure after it returns. This lead-in rule applies to the MCP App widget only; any visualization you create yourself may appear wherever you judge best. INPUTS: every parameter is OPTIONAL and defaults to a sensible value. Call this tool IMMEDIATELY — pass only the values the user explicitly stated and omit the rest. Do NOT ask the user for starting values, assumptions, or missing parameters before calling; the rendered widget has editable fields so they adjust age, amounts, and other assumptions inline after it appears.

Retirement projection for monthly contributions to the Savvly Longevity Benefit over a number of years. Returns payout amounts at milestone ages 80/85/90/95 with Savvly vs market alone cumulative totals, per-age breakdowns, and server-provided `_lower`/`_upper` range bounds. Use `_upper` as the central illustrative estimate and `_lower` to communicate downside. Suitable for retirement savings planning, annuity alternative comparison, and longevity benefit illustration. Supports an optional annual contribution increase and an optional early-withdrawal age. Contributions must finish by age 80: an omitted `contribution_years` auto-fits this, and an explicit one must satisfy `current_age + contribution_years` ≤ 80. Disclaimers + per-field hints under `metadata`. Payout methodology — Savvly vs market alone: the payout values are calculated by comparing two investors of the same age committing the same principal. Investor 1 invests in the market with the Savvly Longevity Benefit; Investor 2 invests in the market alone (no longevity overlay).
