🟢get_market_snapshot
Latest U.S. mortgage rates, TBA par coupons, Treasury and SOFR benchmarks, and mtgmon's fitted MBS basis in one call. No arguments. Use for: "what are mortgage rates today", 30y vs 15y, current coupon, 2y/10y Treasury, SOFR swap levels, whether MBS spreads are rich or cheap versus the model. Do not use for: rate history (not exposed here) or GSE loan performance (get_loan_performance). Returns data.rates, a list of up to 9 points {series, date, value, previous_value, change} for series MORTGAGE30US and MORTGAGE15US (Freddie Mac PMMS, weekly), tba_par_coupon_30y and tba_par_coupon_15y, 2Y and 10Y Treasury, and SOFR O/N, SOFR 2Y, SOFR 10Y; plus data.mbs_basis {model_version, latest_date, latest_basis_bps, latest_fair_bps, latest_gap_bps, latest_gap_zscore, r2_level_full_sample, ec_half_life_days, ...}. Rates are percent, basis is basis points. Series have different observation dates; quote each point's own date. Behavior: read-only, no auth or API key, no PII, idempotent and safe to retry. The public endpoint https://mtgmon.com/mcp allows about 60 requests/min and 250 tool calls/day per client IP. Result shape is {data, meta}; meta carries available, as_of, source_scope, weighting, units, cache_status, caveats, and truncated. If meta.available is false the data is unavailable or the cache is still warming (retry after a few seconds); never report it as zero.

}🟢get_loan_performance(topic, gse, from_date, to_date, max_points, ...)
Fannie Mae and Freddie Mac single-family loan-performance analytics for exactly one topic. Topics: - credit: monthly origination FICO and LTV (origination-UPB weighted). data.series {fico, ltv} and data.latest. - prepayment: monthly CPR and SMM (UPB weighted). - delinquency: monthly 30/60/90+ day delinquency rates (UPB-weighted stock rates). - loss: monthly loss severity (percent) and net loss (USD billions), plus data.latest_waterfall. - vintage: cumulative default-rate curves by vintage year over loan age (data.series = [{vintage, points}]). - transitions: loan-level monthly flows between Current/DQ30/DQ60/DQ90+/Modified/Liquidated (data.flows, top_n rows of {from, to, loans, upb, prob}) and data.history {cure_history, roll_30_60_history, roll_60_90_history}. - modification: outcomes at 6/12/18/24/36 months after a first 90+ DPD event, Modified vs NotModified arms (data.horizons, data.outcome_states, data.cohort_size, data.pooled, data.recent_vintages). - rate_sensitivity: modelled CPR under rate shocks (data.scenario = [{rate_shock_bps, predicted_cpr}], data.model {current_rate, current_cpr, slope}). - lock_in: active book by WAC vs today's mortgage rate: data.summary {total_upb, loan_count, wac_weighted, pct_below_mtg, pct_200bps_otm, pct_100bps_otm, pct_in_money} and data.largest_wac_age_cells {wac, age_band, upb}. Use for: agency credit quality, prepayment speeds, delinquency, roll and cure rates, modification outcomes, losses, the lock-in effect. Do not use for: originator volume or market share (search_lenders / get_lender_profile), today's rates (get_market_snapshot), per-servicer performance (get_servicer_analytics). Time-series topics return data.series {metric: [{date, value}, ...]} downsampled to max_points, plus data.latest. Scope is public GSE loan-level disclosures, not the whole U.S. market; meta.as_of is the latest reporting month. Behavior: read-only, no auth or API key, no PII, idempotent and safe to retry. The public endpoint https://mtgmon.com/mcp allows about 60 requests/min and 250 tool calls/day per client IP. Result shape is {data, meta}; meta carries available, as_of, source_scope, weighting, units, cache_status, caveats, and truncated. If meta.available is false the data is unavailable or the cache is still warming (retry after a few seconds); never report it as zero.

}🟢search_lenders(query, charter, state, min_volume, sort, ...)
Find HMDA lenders and resolve names to canonical lender keys. Call this before any other lender tool. Use for: turning a company name ('Rocket', 'UWM', 'Wells Fargo', 'PennyMac') into its canonical key, ranking lenders by origination volume, or listing lenders by charter type or headquarters state. Then pass a result's exact `name` (e.g. 'Rocket/Quicken') as `lender` to get_lender_profile, get_hmda_product_analytics, or get_servicer_analytics mode='transfers', or as lender_a / lender_b to compare_lenders. Legal names such as 'Rocket Mortgage, LLC' are not keys and return meta.available=false downstream. Returns data.results (at most `limit` rows of {name, leis, charter_type, hq_state, recent_year, recent_volume, total_loans, volume_rank, subsidiary_count}), data.matched_count, and data.total_count. recent_volume is USD originations in recent_year (the latest HMDA year). Keys are holding-company or originator groups, so subsidiaries and LEIs roll up into one key. Behavior: read-only, no auth or API key, no PII, idempotent and safe to retry. The public endpoint https://mtgmon.com/mcp allows about 60 requests/min and 250 tool calls/day per client IP. Result shape is {data, meta}; meta carries available, as_of, source_scope, weighting, units, cache_status, caveats, and truncated. If meta.available is false the data is unavailable or the cache is still warming (retry after a few seconds); never report it as zero.

}🟢get_hmda_product_analytics(year, state, lender, product_family, credit_structure, ...)
HMDA origination counts, reported dollar amounts, averages, and year-over-year growth for one product family, optionally for one property state or one lender, with an annual history back to 2018. Use for: HELOC, reverse-mortgage, or closed-end mortgage origination volume and growth; product mix by loan program (conventional/FHA/VA/USDA), purpose, lien, occupancy, construction method, or business purpose; state-level or lender-level product questions. Do not use for: lender rankings or market share (search_lenders / get_lender_profile) or GSE loan performance (get_loan_performance). Important: product_family defaults to 'heloc'. Use 'closed_end_mortgage' for ordinary mortgages or 'all' for every HMDA origination. Source is the frozen annual FFIEC/CFPB HMDA Snapshot LAR (one release per year, 2018 onward); state filters use the property state, not the lender's headquarters. Returns data.selected_year, data.current and data.previous (each {year, origination_count, reported_amount_count, reported_amount_sum, average_reported_amount, reported_amount_max, origination_count_yoy_pct, reported_amount_sum_yoy_pct, average_reported_amount_yoy_pct}), data.history (one such row per year), data.filters (applied filters), data.definition, and data.source_releases. Amounts are USD; YoY fields are percent; for HELOCs the amount is credit available, not the drawn balance. Behavior: read-only, no auth or API key, no PII, idempotent and safe to retry. The public endpoint https://mtgmon.com/mcp allows about 60 requests/min and 250 tool calls/day per client IP. Result shape is {data, meta}; meta carries available, as_of, source_scope, weighting, units, cache_status, caveats, and truncated. If meta.available is false the data is unavailable or the cache is still warming (retry after a few seconds); never report it as zero.

}🟢get_lender_profile(lender, top_n)
HMDA profile for one lender group: annual origination volume, loan counts, denial rate, national rank and market share, top states with market-share multiples, and loan type / purpose / occupancy / loan-size mix. Requires a canonical key: call search_lenders and pass the exact `name` (e.g. 'Rocket/Quicken'). Any other spelling returns meta.available=false with empty lists. Use compare_lenders for two lenders side by side. Returns data.lender_key, data.name, data.leis, data.current_year, data.previous_year, data.yearly (one row per HMDA year: originated_volume, originated_loans, purchased_volume, purchased_loans, denied_loans, applications_loans, total_funded_volume, avg_loan_size, denial_rate_pct, denial_rate_count_pct, rank, national_volume, market_share_pct), data.top_states {state, volume, loans, previous_volume, previous_loans} and data.state_market_multiples {state, lender_share_pct, market_share_pct, multiple, ...} (top_n rows each), data.loan_type_mix, data.loan_purpose_mix, data.occupancy_mix ({code, label, loans, volume}), and data.loan_size_histogram. Volumes are USD; shares and rates are percent. Behavior: read-only, no auth or API key, no PII, idempotent and safe to retry. The public endpoint https://mtgmon.com/mcp allows about 60 requests/min and 250 tool calls/day per client IP. Result shape is {data, meta}; meta carries available, as_of, source_scope, weighting, units, cache_status, caveats, and truncated. If meta.available is false the data is unavailable or the cache is still warming (retry after a few seconds); never report it as zero.

}🟢compare_lenders(lender_a, lender_b, top_n)
Side-by-side HMDA comparison of two lender groups: yearly volume, loans, rank, and market share for both; loan type / purpose / occupancy mix; and the top states with each lender's volume and the volume multiple between them. Requires canonical keys for both lenders: call search_lenders and pass each result's exact `name`. For a single lender use get_lender_profile. Returns data.lenders, data.current_year, data.previous_year, data.yearly (both lenders per HMDA year), data.loan_type_mix, data.loan_purpose_mix, data.occupancy_mix, and data.top_state_comparison (top_n rows with lender_1_volume, lender_2_volume, multiple). Volumes are USD; shares are percent. Behavior: read-only, no auth or API key, no PII, idempotent and safe to retry. The public endpoint https://mtgmon.com/mcp allows about 60 requests/min and 250 tool calls/day per client IP. Result shape is {data, meta}; meta carries available, as_of, source_scope, weighting, units, cache_status, caveats, and truncated. If meta.available is false the data is unavailable or the cache is still warming (retry after a few seconds); never report it as zero.

}🟢get_servicer_analytics(mode, gse, vintage, lender, top_n, ...)
Agency (Fannie Mae / Freddie Mac) servicer analytics in one of three modes. - mode='scorecard': largest servicers ranked by disclosed origination UPB for the current and previous year with average FICO and LTV. Returns data.servicers (top_n rows of {rank, name, volume, previous_volume, avg_fico, avg_ltv}), data.current_year, data.previous_year. - mode='performance': monthly CPR and 90+ day delinquency per top servicer for one origination vintage against the whole-book benchmark. Returns data.servicers {name: {cpr: [{date, value}], dq90: [...]}} downsampled to max_points, data.book {cpr, dq90}, data.vintage, data.latest_date. - mode='transfers': where one originator's Fannie Mae loans are serviced today and how servicing moved from the seller. Requires `lender` (canonical key from search_lenders). Returns data.seller_name, data.summary {loan_count, origination_upb, loans_with_transfer, pct_loans_with_transfer, total_transfer_events, ...}, data.latest_active_servicers {servicer, loans, upb, upb_share_pct}, data.top_routes and data.top_named_routes {from_servicer, to_servicer, events, event_share_pct}, data.first_to_latest {first_servicer, latest_servicer, loans, original_upb} (top_n rows each). Use for: "largest servicers", "which servicer prepays fastest or has the worst DQ for the 2021 vintage", "who services Rocket's loans now". Do not use for: HMDA origination volume (get_lender_profile) or book-wide delinquency (get_loan_performance topic='delinquency'). Coverage is disclosed agency loans matched by seller/servicer name, not any servicer's full portfolio. UPB and volume are USD; CPR and DQ90 are percent. Behavior: read-only, no auth or API key, no PII, idempotent and safe to retry. The public endpoint https://mtgmon.com/mcp allows about 60 requests/min and 250 tool calls/day per client IP.

}🟢search_sec_filings(query, cik, ticker, form, from_date, ...)
Search SEC EDGAR filings of mortgage-related public companies (lenders, servicers, mortgage REITs, insurers, GSEs) that mtgmon has summarized. Newest filing date first. Use for: finding a company's 10-K, 10-Q, 8-K, or other filings by ticker, CIK, form type, keyword, or date window, and getting the filing_id to pass to get_sec_filing. Do not use for: full filing text (only summaries are stored) or companies outside the mortgage sector. Returns data.filings (at most `limit` rows of {filing_id, accession_number, filer_cik, form, filing_date, company_name, description, summary_status, summary_excerpt, summary_created_at, edgar_url}) and data.next_cursor (pass back as `cursor` for the next page; null when exhausted; meta.truncated is true when more pages exist). Only filings whose summary processing finished are listed; summaries are machine-generated and should be checked against edgar_url. Behavior: read-only, no auth or API key, no PII, idempotent and safe to retry. The public endpoint https://mtgmon.com/mcp allows about 60 requests/min and 250 tool calls/day per client IP.
