- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 300000)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

- pass `tools.annotations`: 9 of 9 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 5,103 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 19 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

## Packages

_none_

## Tools (9)

- `get_net_worth`: Net worth history + account balances. Numbers to reason with — to display, use net_worth_trend.
- `get_spending_breakdown`: Categorized spending + prior-period comparison. Numbers to reason with — to display, use spending_breakdown.
- `get_subscriptions`: Recurring-charge detection. Numbers to reason with — to display, use the subscriptions card.
- `get_transactions`: Raw transactions by category or merchant, ~12 months of history. Numbers to reason with — to display, use transaction_list.
- `net_worth_trend`: Render net_worth_trend: Net worth: current total, change over the period, a trend chart, and the account balances behind it. It loads its own data. To compare periods against each other pass chartStyle:'bar' plus groupBy ('year' for this-year-vs-last-year, 'month' for month-by-month) — each bar is that period's closing balance.
- `spending_breakdown`: Render spending_breakdown: Spending split by category for a period: a composition bar plus a ranked category list. It loads its own data — pass the period alone for the whole picture, which is what a broad 'where did my money go' question wants. Use highlight only on a follow-up about particular categories; it dims everything else, so on an opening question it hides most of the answer.
- `subscriptions`: Render subscriptions: Recurring charges: total monthly cost and a row per subscription with its cadence, next charge date, and New / price-increase flags. It loads its own data.
- `transaction_list`: Render transaction_list: Individual purchases for a category or a merchant: the window total plus the matching transactions. It loads its own data. Plain terms like 'restaurants', 'groceries' or 'gas' resolve to categories; omit both filters for all spending. Do NOT use this when the user asks how much they spent over the last 3, 6 or 12 months — that is a period comparison, so use trend_card with chartStyle:'bar' instead.
- `trend_card`: Render trend_card: Any metric over time that has no dedicated card — one category's spend by month, a series you computed. Points are {label, value} in display order. Set upIsGood=false for cost-like metrics. Use chartStyle:'bar' whenever the user compares periods — month by month, or over the last 3/6/12 months; give each point a `series` name (repeating the label once per series) to stack them with a legend. Pass `items` to list the composition behind the number.
