# Dirigon

> Private credit look-through from SEC filings. Same loan, different marks, across BDCs, interval funds, and listed CLO CEFs.

Dirigon is a terminal + hosted MCP/API for private-credit marks from SEC EDGAR (BDC, interval, and listed CLO CEF schedules of investments). We match the facility. A fund blend is not a mark. This is not a stock-market API or a general SEC-fundamentals feed.

## What you can do without a key

Read this file, `/agents.md`, `/skill.md`, and `/docs/*.md`. You will not get live marks without auth. Do not guess holdings.

Public HTML (no key): https://dirigon.com/private-credit · https://dirigon.com/managers · https://dirigon.com/managers/blackstone · https://dirigon.com/managers/blue-owl · https://dirigon.com/managers/ares · https://dirigon.com/managers/goldman · https://dirigon.com/managers/hps · https://dirigon.com/funds/bcred · https://dirigon.com/funds/obdc · https://dirigon.com/funds/arcc · https://dirigon.com/marks

## Auth (one rule)

- Interactive clients (Claude, Cursor, ChatGPT, Claude Code, Codex): **OAuth**. Sign in with the mailbox on the plan. Do not put a key in mcp.json.
- Scripts / workers / curl: header `X-API-KEY` from an env var. Mint at https://dirigon.com/billing → account. Secret shown once. Do not paste keys into a chat.

## First prompt by plan

| Plan | First prompt | Tools |
|---|---|---|
| Trial | lookup q=Coupa. Who holds it, and how do they mark the same loan? | lookup, get_issuer, get_facility |
| Tape | Open ARCC. What is book vs as-filed? Then five SOI lines. | lookup, get_coverage, get_filer, get_positions |
| Matched | lookup q=Coupa. Open get_issuer for every holder and the mark they filed. | Tape + issuers + sector + NA + get_scan + get_digest + get_sits |
| Terminal | Show the widest same-loan disagreements this quarter, on fair value versus principal. | All |

One-liners (public copy):

- Trial: Who holds Coupa, and at what mark? Free for 7 days.
- Tape: Open ARCC. Book vs as-filed and the SOI tape. $20/mo.
- Matched: Coupa holders+marks and the fund tape. $200/mo.
- Terminal: Widest same-loan disagreements + /app. Invite.

Tape is fund-only (ARCC / SOI / book vs as-filed). Coupa holders and look-through live on Trial or Matched. Disagreement is Terminal.

A call outside the plan returns HTTP 402 with a legal alternative. Meter: most calls 1 unit; issuer history 5; SOI tape 10.

## MCP tools

Start with `lookup` (`q=` borrower or ticker). Then deepen:

- `lookup` - Everyday query. Short card + next. `full=true` for deep card.
- `get_issuer` - Credit card: same-loan marks, family, history, recap (new paper, not a recovery). Whole-token `q=`. Hop `facilities[].facility_id` into `get_facility`. Open `get_facility` on `default_facility` when no row is picked. Do not merge family ids.
- `get_facility` - One facility (instrument × maturity). Holders, marks, as-of, liens. Not the issuer book. `issuer_id` + `key`, or `facility_id`. Revolvers are never SAME LOAN.
- `get_disagreement` - Widest same-loan spreads (4+ holders, 15pt+, vintage hidden). n is issuers, not facilities. Defaults match the terminal Disagreement screen (MIN HLD 4 · MIN DISP 15 · HIDE VINTAGE). Pass `issuer_id` for the card.
- `get_filer` - Fund card (ticker or cik). Chips: BCRED, OBDC, OCIC, ARCC, HLEND, ADS, ASIF.
- `get_positions` - SOI lines for one fund (`cik` required; `q=` borrower). Prefer filter before paging. n is the tape, not the analytics book. If `marks_status=null_marks`, sampled marks are null; do not silent-sum `fv_m`.
- `get_non_accrual` - Footnoted NA only.
- `get_coverage` - Snapshot size + `meta.compile_id` + `start_here`. Not accuracy-complete; not a seating audit.
- `get_sector` - Sector mix. Software membership is `lookup q=software book`.
- `get_clo_tranche` - Listed CLO CEF notes (`tranche_key`). Off Find Credit.
- `get_scan` - Morning tiles. Copies scan.json. Disagreement is SAME LOAN, not issuer-book.
- `get_digest` - Morning change pack. Copies digest.json.
- `get_sits` - Special sits. Copies sits.json. Cheap NAV, 95¢ residual on tagged D/E, run-rate dividend path, claims vs later tagged facts. Residual is a scenario, not a mark.

Empty issuer search: the name may sit unmatched on a fund tape. `get_filer` then `get_positions cik=… q=name`. Never report “no holdings” without checking the tape when FV may exist.

## Trust rules

- Marks are fair value / cost from the filed SOI. `1.00` ≈ par. Money fields are $ millions.
- SAME LOAN = matched facility on one as-of - not issuer high−low, not family total (`family_fv_m`). A fund blend is not a mark.
- If `blocked` is true, skip comparisons.
- Cite `meta.compile_id` on every answer.
- Canva ≠ Canvas Medical. Prefer exact / primary hit (`issuers[0]`).
- Do not claim every answer is trusted. Follow `marks_status`, `blocked`, empty hints, and HTTP 402.

## Manager chips (examples, not full roster)

- Blackstone private credit → `BCRED`
- Blue Owl → `OBDC`, `OCIC`
- Ares → `ARCC` (CIK 1287750)

## Spec note

Prefer `/v1/fields.json` and this file over OpenAPI alone - positions borrower `q=` may be missing from the YAML while MCP supports it.

## Empty marks

If holders or FV are present but marks are empty, follow `marks_status` (equity_only | na_only | unmatched_tape | blocked) - never invent “no mark.” Canva-class: equity may be ~153¢ labelled, not street SAME LOAN.
