  • ask_pipeworx_beta

    Beta version of ask_pipeworx: identical universal router (same 7,210 tools, same arguments, same response shape) with candidate routing improvements enabled live whenever one is under test. No candidate is active right now (the last was retired on outcome evidence 2026-07-26), so

  • ask_pipeworx_grounded

    Hallucination-resistant answer mode for high-stakes reads. Same routing as ask_pipeworx — picks the right tool from 7,210 across 1872 sources, fills arguments, fetches the data — then EXTRACTS the answer using ONLY what the tool result contains. Returns {answer, evidence (verbati

    Cancel a subscription by id. Ownership is enforced — you can only cancel your own subscriptions. The row is deactivated (not deleted) so its historical events stay available via recent_alerts.

  • list_subscriptions

    List the caller's active subscriptions. Returns id, type, params, created_at, last_fired_at, fire_count for each. Use this to review what you're monitoring before adding more or to find an id to cancel.

    Realizable-vs-theoretical edge check against live CLOB order-book depth — AND Polymarket's own taker fee, which is never zero and is folded in rather than left for you to add (fleet #3446: r/PredictionsMarkets flagged a "clean" fill that quietly omitted it as optimistic in the di

@pipeworx/sec-nport

Mutual fund and ETF portfolio holdings and fund profile, from SEC Form N-PORT and Form N-CEN. Keyless.

Part of Pipeworx — an MCP gateway connecting AI agents to 1866+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

  • nport_fund_owners(security, quarter?, limit?) — which funds and ETFs hold a stock or bond, ranked by position size. Takes a ticker, a company name, or a CUSIP.
  • nport_fund_portfolio(fund, quarter?, limit?) — one fund's reported positions, largest first.
  • nport_fund_profile(fund) — a fund's profile: ETF/index/money-market status, AUM, expense ratio, advisory fee, NAV/market price per share, and investment adviser(s). From SEC Form N-CEN, the annual fund census — see "Fund profile" below.
  • nport_holdings_coverage() — which N-PORT and N-CEN releases are loaded, how current they are, and what the data does not cover.

The inversion is the point of this pack

"Which ETFs hold the largest positions in NVDA?" returned no_match before this shipped, and the router explained the gap in its own words: it would have to check each ETF individually. edgar_fund_holdings goes fund → holdings. Nothing went security → funds, because SEC publishes N-PORT filing-first and so does every API over it. That is a shape problem, not a rate-limit problem.

This is not 13F warmed over. 13F is institutional managers over $100M, long US equity only. N-PORT is registered funds — mutual funds and ETFs — and carries their bond positions too. "Which funds hold this corporate bond" has no 13F answer at all.

Scope, stated because a partial load read as a complete one is a wrong answer

The quarterly archive is 441MB across 32 tables. Loaded: equity, preferred and debt positions — about 3.6M of the 5.35M holdings rows per quarter, across 14,416 funds. Not loaded: derivatives, loans, repos and structured products. A swap notional is not a holding of the underlying, and reporting it as one would be a wrong answer wearing a right one's clothes. Every response carries this in its scope field.

Two more caveats ride on every answer:

  • N-PORT is filed monthly but released publicly on a quarterly lag, roughly 60 days after the quarter ends. Responses carry as_of_period. An answer that implies real-time is wrong.
  • N-PORT has no ETF flag. These are registered funds, which include ETFs and mutual funds alike; the series name is the only hint. An ETF-only answer cannot be given honestly from this filing, so the pack says that rather than inventing the classification.

Where the data lives, and why it is not in R2

All of it is in Postgres. Measured on the live database, one release loaded:

That is a real amount of Postgres for one pack, so the choice is worth stating rather than leaving for someone to rediscover at 3am.

The query is the reason. The inversion this pack exists for — *which funds hold this security* — is a selective lookup on cusip and issuer_name returning tens of rows out of 3.6M. That is precisely what a B-tree index is for: it answers in milliseconds and touches almost none of the 1.1GB. R2 has no indexes. Serving the same question from object storage means either scanning the objects or building a side index to point into them, which is a worse database than the one already here.

R2 earns its place when the access pattern is *bulk*: whole-file reads, archival quarters nobody queries interactively, or payloads too large to index usefully. A reasonable split later is hot quarters in Postgres, cold quarters in R2 — but that only pays once several quarters are loaded, and today exactly one is. Splitting now would add a storage tier to save nothing.

Where the line is, so the next person does not have to guess. Each quarter costs roughly 1.1GB. Around four to six loaded quarters this becomes the largest single consumer in the database and the cold-quarter split should be built rather than discussed. sec_13f_holdings sits at 3.8M rows for comparison — this pack is the same order of magnitude, not a new class of problem.

Fund profile, from a different filing (N-CEN, not N-PORT)

nport_fund_profile answers a different question than the other three tools: not "what does this fund hold" but "what *is* this fund". It reads SEC Form N-CEN, the annual fund census, which carries fields N-PORT's holdings filing does not:

  • An explicit ETF/exchange-traded-managed-fund/index/money-market/target-date flag — N-PORT has none of these; the series name is the only hint there.
  • Expense ratio (net annual operating expenses, percent of net assets) and advisory fee — populated mainly for closed-end funds; most open-end funds and ETFs leave these N-CEN items blank, and the tool reports that as null, never 0.
  • Investment adviser(s), by name, CRD number and LEI, including subadvisers.
  • AUM (monthly average net assets, or daily average for money market funds) and NAV/market price per share.

What it cannot answer: inception date. N-CEN's structured data set carries no such field — checked against SEC's own 53-table schema (ncen_readme.pdf) before this was built, not assumed. Every response says so explicitly rather than omitting the field.

Why this can be a year stale. N-CEN is filed annually, once per fund per fiscal year. SEC still releases the structured data quarterly because funds' fiscal year ends are spread across the calendar — one release quarter alone covers only the funds whose year ended in that window (measured against the live 2026q3 release: 2,330 of roughly 9-10k active funds). The ingest script loads a trailing four-quarter window for near-complete single-year coverage. report_ending_period on every response is the fund's own fiscal year end, not today.

ETFs organized as unit investment trusts (SPY, QQQ, DIA) ARE covered, through a separate N-CEN section. A UIT reports its fund-level data through N-CEN's Part F / UIT.tsv table (EXISTING_SERIES_CNT, TOTAL_ASSET_FOR_ALL_SERIES, keyed by accession only, no per-series row) rather than through Part C/D's FUND_REPORTED_INFO.tsv. nport_fund_profile tries Part C/D first and falls back to the UIT table when nothing matches there — verified live against SPDR S&P 500 ETF Trust (SPY, CIK 884394): its 2026 filing (accession 0001410368-26-023904) carries zero FUND_REPORTED_INFO rows but a UIT.tsv row reporting TOTAL_ASSET_FOR_ALL_SERIES of $712,072,540,255.17. A UIT profile returns fund_type: "unit investment trust", total assets, and administrators (a UIT has no investment adviser in the usual sense — it is passively administered) — but no expense ratio, advisory fee, or NAV/market price, because Part F does not report those items at all; uit_profile_note says so on every UIT response. Its N-PORT holdings are separately and fully covered by nport_fund_portfolio/nport_fund_owners (confirmed live: SPY is in sec_nport_funds under registrant "State Street(R) SPDR(R) S&P 500(R) ETF Trust").

Name matching is graded, never a silent best-guess. A query is matched against fund_name with ILIKE '%query%' over a wide candidate pool, then ranked client-side — exact (after normalizing punctuation and generic suffixes like "ETF"/"Trust"/"Fund") beats a prefix match, which beats a plain substring match. The response always carries name_match and, for anything short of exact, a name_match_note plus other_candidates (each with its own grade) — so a contains-match is never presented as *the* fund without saying so. Before this, ranking fell back to whichever ILIKE candidate had the most recent report_ending_period, which could and did pick an unrelated same-family fund over the one actually meant.

Ticker resolution

The holdings table keys on CUSIP, which is proprietary to CUSIP Global Services, so this pack does not build or cache a bulk CUSIP↔ticker table. A ticker-shaped input resolves live through OpenFIGI (Bloomberg FIGI, openly licensed) to a canonical company name, which is then matched against issuer_name in our own already-ingested rows — preferring the candidate that is not an ETF or option wrapper, because "NVDA" otherwise matches *Direxion Daily NVDA Bull 2X* right alongside NVIDIA and ranks them together. Same discipline as the 13F pack, deliberately.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{

"mcpServers": { "sec-nport": { "url": "https://gateway.pipeworx.io/sec-nport/mcp" } } }

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/sec-nport/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{

"mcpServers": { "pipeworx": { "url": "https://gateway.pipeworx.io/mcp" } } }

Both URLs reach the same gateway and the same 1866+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/nport_fund_owners \

-H 'Content-Type: application/json' \ -d '{"security":"NVDA","limit":10}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/nport_fund_owners. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Run it from npm

@pipeworx/mcp-sec-nport is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/sec-nport/mcp endpoint shown above. It needs network access; there is no offline mode.

{

"mcpServers": { "sec-nport": { "command": "npx", "args": ["-y", "@pipeworx/mcp-sec-nport"] } } }

Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": " " } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.

It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.

Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.

Using with ask_pipeworx

Instead of calling tools directly, you can ask q
