工具名称和描述与服务器在 2026年11月7日 报告的完全一致。这些内容由作者撰写,不是我们写的;我们以纯文本形式显示。
ncsx_latestThe one number to quote — use this first for "what is NCSX-IS / what is the spread right now". Returns a compact record: headline issuance spread (coupon minus the Treasury yield of matching tenor on the pricing date, weighted by face value), the secured and unsecured sub-indices
ncsx_indexThe full index definition, not a single number — use when the question is structural ("how is NCSX-IS built", "show all tiers") rather than "what is the level". Returns the NCSX-IS / secured / unsecured tiers side by side with each tier's notional and constituent count, plus inde
ncsx_constituentsThe whole universe in one response — all 13 constituent bonds, no filter: issuer, ticker, coupon, maturity, size, seniority, pricing date, tenor, the matched Treasury yield on that date, and the resulting issuance spread in bp. Use it to list the index or to compute weights; if t
ncsx_bondFiltered lookup for one issuer, ticker or note keyword (e.g. "CoreWeave", "GLXY", "Helios", "2031") — returns only the matching constituent bonds, not the whole universe. Constituents are identified by issuer + coupon + maturity; they do NOT carry CUSIPs, so never query by CUSIP.
ncsx_curveThe US Treasury par-yield curve used on the pricing date (14 tenors, interpolated linearly, never extrapolated) plus its recent history. Every constituent spread is measured against this curve.
ncsx_sectorContext series for the AI-infrastructure credit complex: US high-yield OAS, US investment-grade OAS and related ICE BofA indices, with 30-day change and daily history — use these to compare NCSX-IS against the broader market.
ncsx_filingsSEC filing radar for the 9 AI-infrastructure issuers covered by SpreadBench (6 in NCSX-IS plus Nebius, IREN and Hut 8 on the watchlist): every filing from the last 45 days, noise forms (ownership, routine) filtered out, pricing-chain forms (FWP, 424B*, S-3*, F-10) flagged with pr
ncsx_marksSecond, independent layer: quarterly fair-value marks for AI-infrastructure bonds as reported by US registered funds on SEC Form N-PORT (Level 2), converted to spread over the matched Treasury. Compare with NCSX-IS to see issuance spread vs. mark spread.
ncsx_wallMaturity wall for AI-infrastructure bonds: outstanding face value by maturity year, split secured / unsecured, with the full bond list per year. As of 2026-11-04, $17.86B (63.6% of the index) matures in 2031, and 7 of those 8 bonds priced within 2026 — a single issuance window pr
ncsx_storiesCitable data stories (editorial layer) recomputed live from the same public data as the index, each with headline numbers, bilingual page URLs and a ready-to-post 1200x630 share card: (1) the maturity wall of the peak year; (2) the CoreWeave repricing — every CoreWeave bond widen
ncsx_factsThe quotable-facts layer: 16 pre-computed, individually sourced numbers covering the whole index — index and sub-index levels, the secured-vs-unsecured structure premium, universe size, per-bond spread range, peak maturity year and its share, the 2030 window, N-PORT marks coverag
ncsx_eventsThe index history — use this when the question is "how did NCSX-IS get to its current level" rather than "what is the level". NCSX-IS is event-driven: it only moves when a new bond prices, so the history is a replay of 13 pricing events from 2025-05-19 to 2026-07-24. Each event r

SpreadBench NCSX-IS — MCP server
Official Model Context Protocol server for SpreadBench NCSX-IS, an issuance-spread benchmark for AI-infrastructure (Neocloud) bonds.
What NCSX-IS measures. For each constituent bond, the coupon minus the US Treasury yield of matching tenor on that bond's pricing date, weighted by face value. It is a point-in-time issuance spread — event-driven, no daily frequency, and not a traded CDS level or a rating. SpreadBench publishes no credit ratings and no investment advice.
Live data: https://spreadbench.com · Methodology + DOI: https://spreadbench.com/methodology.html · JSON API: https://spreadbench.com/api.html
Two ways to connect
1. Remote (streamable-http, nothing to install)
{
"mcpServers": { "ncsx": { "type": "streamable-http", "url": "https://spreadbench.com/mcp" } } }
Free, no API key, no signup.
2. Local (stdio, same tool set)
npm install -g github:BrianTian818/spreadbench-ncsx-mcp
or, without npm registry:
npm install -g https://spreadbench.com/download/ncsx-mcp-0.3.0.tgz
{
"mcpServers": { "ncsx": { "command": "ncsx-mcp" } } }
Both transports share one tool definition file (tools.js), so they never drift apart.
Tools
Fourteen read-only tools, all keyless. Every tool declares readOnlyHint: true / destructiveHint: false, so clients do not prompt for write permission.
| Tool | Returns |
|---|---|
ncsx_latest | Start here for "what is the level". Latest NCSX-IS reading, secured / unsecured sub-indices, constituent and issuer counts, notional, as-of date, methodology version, DOI, data_status |
ncsx_index | Structural, not a single number. Full index definition, sub-index notionals, coverage notes |
ncsx_constituents | The whole universe, no filter. All 13 constituent bonds: issuer, ticker, coupon, maturity, size, seniority, pricing date, matched Treasury, issuance spread in bp |
ncsx_bond | Filtered lookup for one issuer — matches issuer / ticker / note keyword and returns only matching bonds |
ncsx_curve | The Treasury par-yield curve used on the pricing date (14 tenors, linear interpolation, no extrapolation) plus recent history |
ncsx_sector | US high-yield / investment-grade OAS reference series for comparison |
ncsx_filings | SEC filing radar for 9 AI-infrastructure issuers, last 45 days, noise forms filtered; pricing-chain forms (FWP / 424B* / S-3*) flagged pricing_signal |
ncsx_marks | Second, independent layer: quarterly fair-value marks from SEC Form N-PORT filings, converted to spread |
ncsx_wall | Maturity wall by year with secured / unsecured split; pass year to drill into one cohort |
ncsx_stories | Citable data stories recomputed live, each with headline numbers, bilingual page and a 1200x630 share card |
ncsx_facts | 16 quotable numbers, each with value, unit, as_of, a human-readable calc and a source; filter by id or q |
ncsx_events | History as an event replay. 13 pricing events in order, level after each, change in bp and per-bond pull attribution (pull_bp), so pulls sum to the event delta; filter by since or ticker |
ncsx_ruler | Reverse pricing. Given a coupon and a tenor: interpolated Treasury (never extrapolated), issuance spread, rank among the 13, gap to the index level and to the same-structure tier, and the index level after adding the bond at a given size. Pass issuer to get that issuer's own bonds already in the index as a pricing history. Recomputed on every call — nothing is stored. Also returns a like-for-like comparable set (peer_set: median / notional-weighted / range / rank inside the set; peer_window_years defaults to ±1y, and when the window is empty it falls back to the nearest tenor band with the distance stated). |
ncsx_methodology | Methodology version, DOI, license, data sources and their licensing status, full formula chain |
Three names from the demo-era server — ncsx_levels, ncsx_attribution, ncsx_weekly — are not listed any more, but still answer if an old client calls them: they return a structured retirement notice rather than an error.
Read data_status before you quote anything
Every payload carries a data_status field. This is the single most important field in the schema:
data_status | Meaning |
|---|---|
real_issuance | Observed public issuance data. Safe to quote; reproducible from SEC filings. |
retired_seed / seed | A withdrawn demo series. Numbers were generated for layout testing. Never quote as market levels. |
If a tool returns status: "retired", the endpoint was withdrawn — read the replacement field and move on. Nothing in this server will silently hand you demo numbers.
Example prompts
- *"What is the current NCSX-IS spread, and how does the unsecured cohort differ from the secured one?"*
- *"Which CoreWeave bonds are in the index and what spread did each price at?"*
- *"Compare NCSX-IS against the US high-yield OAS over the last 90 days."*
- *"Which Treasury tenors does the index lean on most?"*
- *"Is the NCSX-IS level consistent with the latest SEC N-PORT marks?"*
- *"A $1.5bn 5-year note at 8.25% — where does that price relative to this market, and what would it do to NCSX-IS?"*
- *"How did NCSX-IS get from 517.7bp to 432.3bp, and which issuer pulled it the most?"*
Conventions
- Identifier: constituents are identified by issuer + coupon + maturity. They do not carry CUSIPs — do not query by CUSIP.
- Units: spreads in basis points over the Treasury at pricing. Notionals in USD millions.
- Frequency: event-driven. There is no T+1 update and no daily change field.
- Reproducibility: every number is derived from public filings (SEC EDGAR) and the US Treasury par-yield curve. The methodology page states the exact formula and the interpolation rule.
Notes on naming
Older versions of this server exposed Composite / HY / IG tiers and 90-day daily series. Those came from a demo dataset and were withdrawn on 2026-11-04 in favour of the issuance-spread methodology (v0.2.0-real). The three retired names listed above remain callable only so that old clients receive an explicit notice instead of an error; they are hidden from tools/list.
Directory listings
This server is listed in the official MCP Registry as com.spreadbench/ncsx, and is indexed by Glama (A tier) and brick.blue. glama.json in this repo claims the listing for its maintainer.
