## MCP tools (5)

### `nyfed_repo_operations` (~256 tokens)

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.

Input parameters:

- `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.

### `nyfed_seclending_operations` (~168 tokens)

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".

Input parameters:

- `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.

### `nyfed_soma_holdings` (~287 tokens)

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).

Input parameters:

- `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.

### `nyfed_reference_rates` (~170 tokens)

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).

Input parameters:

- `number` (number): History length when rate_type is not "all". Default 1 (latest only), max 100.
- `rate_type` (string): Default all.

### `nyfed_primary_dealer_stats` (~192 tokens)

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).

Input parameters:

- `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.

## Common questions

### What is the Nyfed Markets MCP server?

Nyfed Markets is an MCP server listed in the public MCP registry as io.github.pipeworx-io/nyfed-markets. New York Fed Markets Data APIs, markets.newyorkfed.org, keyless JSON, no auth wall.… This page covers its npm package (@pipeworx/mcp-nyfed-markets).

### Is the Nyfed Markets MCP server safe to use?

Nyfed Markets scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 Nyfed Markets MCP server expose?

Nyfed Markets exposes 5 tools: nyfed_repo_operations, nyfed_seclending_operations, nyfed_soma_holdings, nyfed_reference_rates, nyfed_primary_dealer_stats. Their descriptions and schemas cost roughly 1,073 tokens of context every time the server is loaded.

### Is the Nyfed Markets MCP server still maintained?

Nyfed Markets is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Nyfed Markets MCP server under?

Nyfed Markets declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Nyfed Markets MCP server?

VerifyMCP ran 16 checks on Nyfed Markets, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
