How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability62
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1207 tokens (~301/item across 4 items; 4 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 Management10
- Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

calculate_asset_loan_payment Asset loan payment and after-tax cost ~264
Calculates the exact monthly payment, total interest and first-year interest for an equipment, truck, tractor, RV, land, manufactured home, ATV, pontoon or other asset loan, and, for business assets, the after-tax cost: first-year tax saving from the Section 179 or bonus deduction plus deductible interest at your marginal rate, first-year net cash, and lifetime after-tax cost. Pair it with calculate_section_179 for the deduction amount.

calculate_bonus_depreciation Bonus depreciation rate and amount (168(k)) ~350
Finds the special (bonus) depreciation rate under IRC 168(k) from the acquisition and placed-in-service dates and applies it after any Section 179 deduction.

Property acquired before January 20, 2025 keeps the TCJA phase-down: 40% if placed in service in 2025 (60% long production). Rules from IRS Notice 2026-11, the 2025 Form 4562 instructions and Pub. 946.

| placed_in_service_date | string | yes | Date the property was placed in service, YYYY-MM-DD. |
| section_179_deduction | number | – | Section 179 amount already taken on this property; bonus applies to what is left. |

Proc. 2026-15; $20,200 / $12,200 for 2025 per Rev. Proc. 2025-16), heavy SUVs over 6,000 and up to 14,000 lb have a Section 179 cap of $31,300 (2025) or $32,000 (2026) with bonus depreciation for the rest, and vehicles over 14,000 lb or exempt designs have no vehicle cap. Applies the more-than-50% business use rule and scales by business use.
