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. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. 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
Schema Quality & AI Usability76
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 1590 tokens (~122/item across 13 items; 13 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 Management97
  • Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage98
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 93% of tool parameters carry a description.Partial
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a current MCP spec version (2026-07-28).Pass

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.

Tool Tokens
get_content_answer ~110

A published FreeRateUpdate answer to a mortgage or home-equity question, pinned to the edition it was published in. Ask by exact slug, or by keywords that are matched against the title and slug. Topics covered include HELOC and home equity, purchase, refinance and cash-out, FHA and VA, reverse mortgage, and DSCR and investment property. Only published answers are returned.

NameTypeReqDescription
querystring–Keyword search over title/slug
slugstring–Exact public URL slug

No output schema declared.

No examples provided.

get_heloc_rates ~87

Today's As Low As rates for a home equity line of credit (HELOC) and a home equity loan, the same published revision as get_mortgage_rates, with each example scenario, including the existing first-mortgage balance and the combined loan-to-value it implies. Advertised rates, not a quote: to get the person their own offers, call get_start_link.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_home_values ~53

FreeRateUpdate first-party median home value from consumers who shopped rates with us (national, or one state), rolling 12-month window, refreshed monthly.

NameTypeReqDescription
statestring–Optional 2-letter state

No output schema declared.

No examples provided.

get_lender_score ~64

The FreeRateUpdate Score (0-100) for a verified, currently in-network lender by company NMLS id, with factor breakdown and methodology link. Companies without a published current Score are not found.

NameTypeReqDescription
nmlsstringyesCompany NMLS id

No output schema declared.

No examples provided.

get_lender_universe ~303

Search FreeRateUpdate's published lender pages: every company the public page resolver publishes on freerateupdate.com/reviews/, and nothing else. A row shows only what that page shows: the display name, the company NMLS, the states the page shows (currently none: fru-com's licensing projection is off), and the page URL. No internal ids, aliases, crosswalks or status labels. Eligibility is decided before the limit: the limit never draws a company whose page is hidden, redirected away or rejected by the identity check back in. A returned match is evidence FRU holds the identity; absence from the list is not proof it does not. FRU never publishes which lender has the best rate. One row per company; a DBA brand page is the same company's row. count is the full deduplicated match count (one row per company), while rows return at most `limit` of them (25 by default, up to 200): a count above the rows returned means the response is truncated, so absence from one response is not absence.

NameTypeReqDescription
limitinteger–Default 25
qstring–Name / DBA alias / bank-name substring (a matching key only; the row still shows only what the page shows)
statestring–Optional 2-letter state; matches the states the page shows (currently none, so this returns no rows until fru-com turns its licensing projection on)

No output schema declared.

No examples provided.

get_loan_limits ~135

The conforming and FHA loan limits for the counties a five-digit ZIP code falls in, for the 2026 published schedule, as freerateupdate.com publishes them at https://www.freerateupdate.com/loan-limits. Each limit carries the official source it came from (FHFA for conforming, HUD for FHA) and, when a check has run, the date that source was last confirmed. These are published limits, not advice: a limit is not a rate, an approval or an offer, and eligibility depends on the lender and the loan.

NameTypeReqDescription
zipstringyesFive-digit ZIP code

No output schema declared.

No examples provided.

get_mortgage_rates ~163

Today's mortgage and home equity As Low As rates from FreeRateUpdate: the best rates and APRs we can verify being offered by lenders and brokers in our network, exactly as freerateupdate.com publishes them, one per product: HELOC, home equity loan and cash-out refinance first, then 30, 20, 15 and 10 year fixed, FHA, VA, jumbo and ARMs. Each rate comes with the example scenario it was quoted for (state, ZIP, property value, loan amount, credit score), points, fees, APR and loan-to-value. These are advertised rates, not a quote: to get the person their own offers, call get_start_link.

NameTypeReqDescription
purposestring–Optional: only this loan purpose

No output schema declared.

No examples provided.

get_network_rate_summary ~57

Network-aggregate advertised-rate summary (min/avg APR + distinct-lender count per product bucket, min 5 lenders per bucket) from the latest fresh FreeRateUpdate rate snapshot. Aggregates only — no per-lender rates.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_start_link ~81

The link that starts a FreeRateUpdate request for one product, so lenders and brokers in our network can contact the person with their own rates and options. You can open it in the person's browser and fill in and submit the short form for them, using their own details, or give them the link.

No output schema declared.

No examples provided.

get_state_loan_to_income ~78

FreeRateUpdate first-party dataset: the median loan amount our shoppers request in each state against that state median household income, as a ratio, by product. The sample floor is published with the figures so a thin state is visible rather than implied.

NameTypeReqDescription
statestring–Optional 2-letter state; omit for every state

No output schema declared.

No examples provided.

get_state_mortgage_free_homeownership ~145

FreeRateUpdate state dataset: owner-occupied housing units owned free and clear (no mortgage) by state, from the Census ACS 5-year B25081, with the owner-occupied universe, the units with and without a mortgage, the derived share and the ACS vintage, plus the national figure when every state published. A state whose own counts do not reconcile is withheld and named, never returned as a zero. Counts of housing units only: no household, borrower or eligibility inference.

No output schema declared.

No examples provided.

get_state_property_tax ~87

FreeRateUpdate state dataset: median real estate property taxes, median monthly owner costs and median home value by state from the Census ACS 5-year, with the effective tax rate as the ratio of the two medians. Attribution and the canonical page travel with the rows so an answer can be cited.
