How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass

Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
nyfed_primary_dealer_stats ~192
FR 2004 weekly primary dealer positioning/transaction survey (aggregate across all primary dealers). mode=list_series (default) browses the keyid catalog — pass keyid_filter (e.g. "treasury", "mbs", "agency") to find the codes you want. mode=latest returns the most recent weekly values for matching keyids. Data is reported for the current "series break" window automatically (definitions can change across windows; pass seriesbreak explicitly to pin one — see mode=list_series output for window ids).
| Name | Type | Req | Description |
|---|---|---|---|
| keyid_filter | string | – | Substring to match against keyid or its description. |
| limit | number | – | Default 50, max 200. |
| mode | string | – | Default list_series. |
| seriesbreak | string | – | Pin a specific series-break window id (e.g. "SBN2024"). Defaults to the current window. |
No output schema declared.
No examples provided.
nyfed_reference_rates ~170
The Desk's own reference-rate publications: SOFR, SOFRAI (30/90/180-day compounded averages + index), EFFR (effective fed funds), OBFR (overnight bank funding), TGCR/BGCR (tri-party general collateral rates). rate_type=all (default) returns the latest value of every rate in one call; a specific rate_type with number>1 returns that rate's recent history including percentile bands and traded volume — detail fred_get_series('SOFR') etc. does not carry (FRED has only the single daily value, no percentiles/volume).
| Name | Type | Req | Description |
|---|---|---|---|
| number | number | – | History length when rate_type is not "all". Default 1 (latest only), max 100. |
| rate_type | string | – | Default all. |
No output schema declared.
No examples provided.
nyfed_repo_operations ~256
NY Fed Desk repo and reverse repo (ON RRP) operation RESULTS — the actual auctions the Desk ran, not a daily rate aggregate. Each operation: total submitted/accepted USD, counterparty counts, award rate(s), breakdown by security type (Treasury/Agency/MBS/SRF). No start_date/end_date -> today's operation(s) only (empty on weekends/holidays). With start_date/end_date -> a date-range search. Use for "today's ON RRP usage", "reverse repo take-up this week vs last", "who's using the SRF". Different from fred_get_series('RRPONTSYD') which only has the daily accepted total, no per-operation detail.
| Name | Type | Req | Description |
|---|---|---|---|
| end_date | string | – | YYYY-MM-DD, inclusive. |
| limit | number | – | Max operations to return, newest first. Default 20, max 100. |
| operation_type | string | – | repo = Desk lends cash (RP); reverserepo = Desk borrows cash (ON RRP). Default all. |
| start_date | string | – | YYYY-MM-DD, inclusive. Triggers a date-range search instead of "latest". |
| term | string | – | Filter to overnight-only or term operations. |
No output schema declared.
No examples provided.
nyfed_seclending_operations ~168
NY Fed Desk securities lending operation results — how much of the SOMA portfolio was lent out today (or in a date range), by operation (seclending = the daily program, extensions = extended-term lending). Returns total par amount submitted/accepted and, when cusips is given, per-security detail. Use for "how active is securities lending today", "was CUSIP X lent out this week".
| Name | Type | Req | Description |
|---|---|---|---|
| cusips | string | – | Comma-separated CUSIP(s) to filter to (partial match). |
| end_date | string | – | YYYY-MM-DD, inclusive. |
| limit | number | – | Default 20, max 100. |
| operation | string | – | Default seclending. |
| start_date | string | – | YYYY-MM-DD, inclusive. |
No output schema declared.
No examples provided.
nyfed_soma_holdings ~287
System Open Market Account (SOMA) portfolio — the Fed's own securities holdings from QE/reinvestment. view=summary (default) gives total by asset bucket (bills, notesbonds, mbs, agencies, tips) over time — the series to read for "SOMA runoff this month". view=treasury/agency with as_of_date gives the full CUSIP-level holdings snapshot for that date (holding_type narrows to bills/notesbonds/frn/tips for treasury, or agency_debts/mbs/cmbs for agency). Pass cusip alone to look up one security's full holdings history regardless of view. Publishes on a ~1-week lag (as_of_date defaults to the latest available, not today).
| Name | Type | Req | Description |
|---|---|---|---|
| as_of_date | string | – | YYYY-MM-DD. Defaults to the latest published SOMA as-of date. |
| cusip | string | – | A single security's CUSIP — overrides view and searches both Treasury and Agency holdings. |
| holding_type | string | – | For view=treasury: all|bills|notesbonds|frn|tips. For view=agency: all|agency_debts|mbs|cmbs. |
| limit | number | – | Max rows to return. Default 20, max 200. |
| view | string | – | Default summary. |
