Tools

lookup - Everyday query. q= a borrower, ticker, CIK, or phrase. Short card plus next. full=true is the deep card. Prefer this for a name.
get_coverage - This compile's universe. funds = AG filers (BDCs + interval) plus CLO CEF tape. bdcs / interval / clo split. credits = peeled issuer_id count. total_fv_bn is $ billions; line fv_m is $ millions. meta.compile_id is the snapshot to cite. dictionary[] defines each field.
get_issuer - issuer_id (or q= with one hit, or an exact name) opens the credit card: same-loan marks, family, history, recap when on the recap tape (new paper, not a recovery). q= matches whole tokens, not substrings. Many hits: thin list. No q: most-held names (thin). preset=disagreement = widest same-loan screen. Open get_facility on facilities[].facility_id (ISS-######:instrument|YYYY-MM) without guessing; default_facility / history_facilities[].key also address one paper. Do not merge family ids. Do not crawl every issuer_id.
get_facility - One facility (instrument x maturity): holders, marks, as-of, liens. Not the issuer book. Pass facility_id (ISS-######:instrument|maturity) or issuer_id plus key (first_lien_term_loan|2029-08). issuer_id alone opens default_facility. Recap paper is a distinct key. same_loan is true only on the matched funded facility; revolvers are never SAME LOAN.
get_filer - Exact ticker or cik= opens the fund card. Quote book.fv_m. fee_schedule is the advisory contract. fees.mgmt_fee_m / incentive_fee_m are tagged expense $m this period (aliases mgmt_m / incentive_m). incentive_status is tagged | untagged | zero_tagged | n/a. Untagged incentive stays null. YTD/not_quarterly is labeled, not silent-absent. Reported SOI marks · not open-market FV · fees != marks. pik_income.interest_pct_tii is quarterly PIK interest divided by total investment income. dividend_pct_tii is separate. pik_pct_debt_fv is any-PIK of debt fair value. all_pik_pct_debt_fv is zero-cash debt. Neither debt share is a share of investment income. A missing pik_income field was not tagged. q= with many hits is a thin list. sort=fv limit=4 is the Allocator starter. get_sector q=software view=funds ranks software books. Chips: BCRED, OCIC, HLEND, ADS, ASIF.
get_positions - Line lookup on one fund SOI. Pass cik from get_filer and q= a borrower. No q: 15 sample lines (limit honors 1-15). Max 100 with q. n is the full tape, not the analytics book. Do not sum fv_m. If marks_status=null_marks, sampled marks are null.
get_disagreement - The disagreement screen: widest same-loan issuer spreads on the latest common period (4+ holders, 15pt+, vintage hidden). n is issuers, not facilities. Stale interval marks do not rank. Pass issuer_id to get_issuer for the card. cursor pages.
get_non_accrual - Lines the funds footnoted as non-accrual. Optional cik or q=credit name. Default 50. cursor pages.
get_sector - Sectors page. No q: universe mix with denominator_fv_m. q=software|healthcare|industrials. view=credits|funds. Software fund ranking uses membership software_pct. Other sectors use printed mix. sort=fv|pct. cursor pages. cik= one fund's mix.
get_clo_tranche - CLO note holder graph. q= or tranche_key= opens one deal|class (holders, marks, vehicles). No q: cross-vehicle connections (BDC / interval / loan_cef sleeves that share a CEF tranche). view=books is per-CEF field fill vs the canonical standard. Off Find Credit. Not collateral, WAS, or OC/IC.
get_scan - Morning desk. No tile: headline and the tile index. tile= returns that list. Leverage history and distribution sleeves are not included. No new math.
get_digest - Morning change pack. Copies digest.json. New filings, watchlist, non-accrual. Assembly, not a second mark engine.
get_sits - Special sits desk. Copies sits.json. Listed BDCs at ≤50¢ of NAV, 95¢ residual on tagged D/E, run-rate dividend path, 8-K claims vs later tagged facts. Residual is a scenario, not a loan mark.

Example

curl https://dirigon.com/v1/mcp \
  -H "X-API-KEY: YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Example prompts (must be legal on the plan)

Trial: lookup q=Coupa. Who holds it, and how do they mark the same loan? Then get_facility on the matched paper.
Tape: Open ARCC. What is book vs as-filed? Then five SOI lines.
Tape+: Open BCRED. What is the book mark vs as-filed?
Tape: Show Ares Capital's Kellermeyer line.
Matched: lookup q=Coupa. Open get_issuer for every holder and the mark they filed. Open get_facility on default_facility.
Matched: Which fund has the most software?
Matched: Which funds flagged Medallia as non-accrual?
Matched: Four largest funds, equal-weight: book mark, PIK, non-accrual. (Allocator starter. Blend the four cards.)
Terminal: Show the widest same-loan disagreements this quarter, on fair value versus principal.
Terminal: Show the widest holder-mark disagreements in software.
