Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →
Supply Chain Security87
- No malware found by supply-chain analysis.Pass
- Known CVEs were checked across the 95 of 99 dependencies we could resolve, so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Dependency health was assessed across the 95 of 99 dependencies we could resolve, so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 8 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability59
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1184 tokens (~148/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management37
- Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage96
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 87% of tool parameters carry a description.Partial
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

- 6 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 33 to 37. That category is still filling its 30-day observation window: 10 days of observed history at the previous scan, 11 at this one. The score rises as the window fills, whether or not the server changes.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The dependency tree was only partially resolved, so these counts may be incomplete.
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
accrued_interest Accrued interest ~180
Exact simple accrued interest (notional * rate * day-count fraction) between two dates. Dates are ISO YYYY-MM-DD; rate is the annual rate as a decimal (0.05 = 5%). Deterministic.
| Name | Type | Req | Description |
|---|---|---|---|
| convention | string | yes | Day-count convention, e.g. ACT/ACT ISDA or 30/360. |
| end | — | yes | — |
| endIsTermination | boolean | — | 30E/360 ISDA only: true if the end date is the instrument's maturity date. |
| notional | number | yes | Face / principal amount. |
| rate | number | yes | Annual rate as a decimal, e.g. 0.05 for 5%. |
| start | string | yes | ISO calendar date, YYYY-MM-DD (e.g. 2024-03-15). Zero-padded, no time or timezone. |
No output schema declared.
No examples provided.
add_business_days Add business days ~138
Move a signed number of business days under a holiday calendar (settlement math: T+2 is count 2). Zero returns the date unchanged. Deterministic.
| Name | Type | Req | Description |
|---|---|---|---|
| calendar | string | yes | Holiday calendar: us-federal (US federal holidays), nyse (NYSE trading days), sifma-us (US bond market), target (euro settlement), uk (England and Wales bank holidays). |
| count | integer | yes | Business days to move; negative moves backward. |
| date | string | yes | ISO calendar date, YYYY-MM-DD (e.g. 2024-03-15). Zero-padded, no time or timezone. |
No output schema declared.
No examples provided.
adjust_date Adjust to a business day ~163
Adjust a date to a business day under an ISDA convention and holiday calendar. Business days pass through unchanged. modified-following falls back to preceding rather than leave the month (the bond-market default). Deterministic.
| Name | Type | Req | Description |
|---|---|---|---|
| calendar | string | yes | Holiday calendar: us-federal (US federal holidays), nyse (NYSE trading days), sifma-us (US bond market), target (euro settlement), uk (England and Wales bank holidays). |
| convention | string | yes | ISDA business-day adjustment convention: following, modified-following, preceding, modified-preceding, or unadjusted. |
| date | string | yes | ISO calendar date, YYYY-MM-DD (e.g. 2024-03-15). Zero-padded, no time or timezone. |
No output schema declared.
No examples provided.
day_count_fraction Day-count fraction ~243
Exact day-count fraction between two dates under a market convention. Dates are ISO YYYY-MM-DD. For ACT/ACT ICMA also pass frequency (coupons per year) and, for stub periods, the reference period boundaries. Deterministic; do not estimate this with a model.
| Name | Type | Req | Description |
|---|---|---|---|
| convention | string | yes | Day-count convention, e.g. ACT/ACT ISDA or 30/360. |
| end | — | yes | — |
| endIsTermination | boolean | — | 30E/360 ISDA only: true if the end date is the instrument's maturity date. |
| frequency | integer | — | ACT/ACT ICMA only, required for it: coupon payments per year (1, 2, 3, 4, 6, or 12). |
| referenceEnd | — | — | — |
| referenceStart | string | — | ACT/ACT ICMA only: reference (notional coupon) period boundary, ISO YYYY-MM-DD. Supply referenceStart and referenceEnd together, or neither. |
| start | string | yes | ISO calendar date, YYYY-MM-DD (e.g. 2024-03-15). Zero-padded, no time or timezone. |
No output schema declared.
No examples provided.
generate_schedule Generate a payment schedule ~282
Generate coupon/payment accrual periods between an effective and a termination date: monthly to annual frequency, backward or forward roll, short or long stub, optional end-of-month rule, business-day adjustment per calendar. Returns each period's unadjusted and adjusted start and end. This is where hand-rolled date code goes wrong; do not approximate it.
| Name | Type | Req | Description |
|---|---|---|---|
| calendar | string | yes | Holiday calendar: us-federal (US federal holidays), nyse (NYSE trading days), sifma-us (US bond market), target (euro settlement), uk (England and Wales bank holidays). |
| convention | string | — | Adjustment for every date except termination. Default modified-following. |
| effective | string | yes | ISO calendar date, YYYY-MM-DD (e.g. 2024-03-15). Zero-padded, no time or timezone. |
| endOfMonth | boolean | — | When true and the anchor is a month-end, every roll date is a month-end. |
| frequency | string | yes | Coupon frequency: annual, semiannual, quarterly, or monthly. |
| generation | string | — | Roll direction; backward (default) puts any stub in front. |
| stub | string | — | Keep the short stub (default) or merge it into its neighbor. |
| termination | — | yes | — |
| terminationConvention | — | — | Adjustment for the termination date. Default: same as convention. |
No output schema declared.
No examples provided.
is_business_day Business-day check ~139
Whether a date is a business day under a holiday calendar, with the reason when it is not (weekend or holiday). Calendars are rules in code (no stale data feed). Deterministic; do not let a model guess market holidays.
| Name | Type | Req | Description |
|---|---|---|---|
| calendar | string | yes | Holiday calendar: us-federal (US federal holidays), nyse (NYSE trading days), sifma-us (US bond market), target (euro settlement), uk (England and Wales bank holidays). |
