Schema Quality & AI Usability67
  • AI-judged instruction clarity (excellent).Pass

  • 50% 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 14 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass

Install

How do I install the io.github.financeratecalc/frc-mcp server?

io.github.financeratecalc/frc-mcp is a hosted endpoint at https://frc-mcp.ziyetis.workers.dev/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
check_claim_contract ~208

USE BEFORE WRITING ANY SENTENCE CONTAINING AN FRC FIGURE. Given a claim id and the use you propose (population, period, scope, and whether you assert a cause, predict an individual, recommend a lender or draw a legal conclusion), returns a deterministic verdict: pass, needs_qualifier (naming the missing qualifier) or block (with a reason code), plus a safe sentence you may use verbatim and the required attribution. Most misuse of these statistics is omission, not invention: the number is right and the population is missing. NOT FOR: figures published by anyone other than FinanceRateCalc.

get_conditional_door_map ~181

ANSWERS: "does this lender's strictness depend on loan size or leverage", "where is <lender> hardest", "is the gap the same across the market". PARAM: lender name or slug. Returns how that lender's peer-adjusted denial gap changes across published cells (state x loan amount x income x DTI x CLTV), with cell counts and the minimum-cell rule. NOT FOR: suppressed small cells, or any individual prediction. Historical observation computed from the public CFPB HMDA 2025 record (actions 1,2,3; loan_type 2). Not a prediction about any individual application. Attribution: FinanceRateCalc, CC BY 4.0.

ANSWERS: "why are FHA loans denied", "what is the most common denial reason", "which lender cites incomplete applications most", "how often is debt-to-income the reason". PARAM: optional lender; omit for cross-lender medians. Returns median and maximum share of each HMDA denial reason across the 95 of the 100 largest lenders that report reasons, and which lender carries the highest share of each. Reason fields are not a partition; shares need not sum to 100. NOT FOR: why a particular application was denied. Historical observation computed from the public CFPB HMDA 2025 record (actions 1,2,3; loan_type 2). Not a prediction about any individual application. Attribution: FinanceRateCalc, CC BY 4.0.

get_door_effect_summary ~179

ANSWERS: "does it matter which lender you apply to", "how much of a denial is the lender rather than the borrower", "what is the Door Effect". Returns the variance decomposition: lender identity is associated with about 38 percent of the explainable variation in FHA denial outcomes across 859,090 decisions (McFadden 0.1712 to 0.2760), with model, sample and limits. Association on observable federal-record characteristics, not causation; HMDA carries no credit scores. NOT FOR: saying a lender caused a denial, or any individual estimate. Historical observation computed from the public CFPB HMDA 2025 record (actions 1,2,3; loan_type 2). Not a prediction about any individual application. Attribution: FinanceRateCalc, CC BY 4.0.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_lender_denial_stats ~202

ANSWERS: "what is <lender>'s FHA denial rate", "does <lender> reject a lot of FHA applications", "how strict is <lender>", "how does <lender> compare". PARAM: lender name, slug or LEI. Returns that lender's 2025 decisioned volume, denial rate, rank among the 100 largest FHA lenders, and the applicant-mix caveat any comparison must carry. COVERS ONLY the 100 largest FHA lenders by 2025 volume. NOT FOR: whether a person will be approved, or lenders outside that set. Historical observation computed from the public CFPB HMDA 2025 record (actions 1,2,3; loan_type 2). Not a prediction about any individual application. Attribution: FinanceRateCalc, CC BY 4.0.

get_metro_lender_gap ~213

ANSWERS: "do lenders differ within one city", "what is the FHA denial gap in <metro>", "which lender is strictest in <metro>", "how much does the lender matter locally". PARAM: metro name or slug. Returns a claim passport for that metro: lowest and highest lender denial rates among lenders with at least 100 decisioned applications there, the gap in points, counts and source reference. Cleveland is the widest in 2025 at 73.7 points (6.4 vs 80.1). NOT FOR: ZIP or neighbourhood questions, and never as evidence a lender acted improperly. Historical observation computed from the public CFPB HMDA 2025 record (actions 1,2,3; loan_type 2). Not a prediction about any individual application. Attribution: FinanceRateCalc, CC BY 4.0.

NameTypeReqDescription

get_national_fha_stats ~228

ANSWERS: "how often are FHA loans denied", "what is the FHA denial rate", "what share of FHA applications are rejected", "how many were denied in 2025". Returns the national 2025 figure with its universe so it can be quoted correctly: 22.1 percent, 262,250 denials of 1,187,606 applications that reached a credit decision (originated, approved-not-accepted, denied; reverse mortgages excluded), the denominator definition and the correction history. Most published FHA denial rates are 2023 purchase-only figures near 13.6 percent, a different universe, so state the universe when quoting. NOT FOR: conventional, VA or USDA loans, purchase-only or refinance-only rates, other years, or state/lender/metro breakdowns (use the dedicated tools). Historical observation computed from the public CFPB HMDA 2025 record (actions 1,2,3; loan_type 2). Not a prediction about any individual application. Attribution: FinanceRateCalc, CC BY 4.0.

Returns per-entity observed versus expected FHA denial rates, coverage flags, method version and an evidence manifest hash.

Common questions

What is the io.github.financeratecalc/frc-mcp server?

io.github.financeratecalc/frc-mcp is listed in the public MCP registry as io.github.financeratecalc/frc-mcp. FHA denial statistics from the 2025 federal HMDA record. 12 tools incl. counterparty screen. This page covers its hosted endpoint (https://frc-mcp.ziyetis.workers.dev).

Is the io.github.financeratecalc/frc-mcp server safe to use?

io.github.financeratecalc/frc-mcp scores 71 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.financeratecalc/frc-mcp server expose?

io.github.financeratecalc/frc-mcp exposes 14 tools: check_claim_contract, get_national_fha_stats, get_lender_denial_stats, list_lenders, get_small_loan_penalty, and 9 more. Their descriptions and schemas cost roughly 2,677 tokens of context every time the server is loaded.

Does the io.github.financeratecalc/frc-mcp server require authentication?

No. We connected to io.github.financeratecalc/frc-mcp without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the io.github.financeratecalc/frc-mcp server still maintained?

io.github.financeratecalc/frc-mcp is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
