MCP tools · 31 exposed · ~4,242 tokens

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 →

Tool Tokens
activist_stakes ~130

The first public signal of an activist position: Schedule 13D and 13G beneficial-ownership filings naming a company over a window, newest first. A fresh 13D is where an activist campaign becomes public. Costs $0.05 per call.

NameTypeReqDescription
companystringyesTicker symbol (e.g. AAPL) or SEC CIK number (e.g. 320193).
daysinteger–Lookback window in days, 30-730. Default 365.
limitinteger–Filings to return, max 100. Default 25.

No output schema declared.

No examples provided.

cftc_positioning ~170

Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Weekly Commitments of Traders positioning for a futures contract: non-commercial (speculative) and commercial (hedging) longs, shorts and net, net as a share of open interest, and the week-over-week changes. Match by contract name fragment such as CRUDE OIL, WHEAT, GOLD or S&P 500. The disclosed record only, no forecast. Costs $0.05 per call.

NameTypeReqDescription
marketstringyesContract name fragment, e.g. CRUDE OIL, WHEAT, GOLD, COPPER, S&P 500.
weeksinteger–Weeks of history per contract, max 26. Default 4.

No output schema declared.

No examples provided.

company_financials ~130

Fetch an as-reported XBRL financial concept for a company across recent periods, each tied to the filing it came from. Note that many issuers report revenue under RevenueFromContractWithCustomerExcludingAssessedTax rather than Revenues; if one returns nothing current, try the other. Costs $0.01 per call. No subscription: present a credit key or a machine payment.

NameTypeReqDescription
companystringyesTicker symbol (e.g. AAPL) or SEC CIK number (e.g. 320193).
conceptstringyesUS-GAAP concept name.

No output schema declared.

No examples provided.

compare_filings ~280

Year-over-year diff of a 10-K risk-factor or MD&A section: the added and removed passages plus a change ratio, so an agent gets what changed instead of two multi-megabyte filings to parse. Pass two accession numbers to pin exactly which filings are compared; otherwise the two most recent of that form are used and the response says which, warning if a later amendment exists. Failure mode: if either section cannot be located or parsed into sentences, the call errors rather than reporting a false 0% change. Diff accuracy and method are published at signalnodus.ai/eval. Two large cold filings can take tens of seconds. Costs $0.50 per call. No subscription: present a credit key or a machine payment.

NameTypeReqDescription
companystringyesTicker symbol (e.g. AAPL) or SEC CIK number (e.g. 320193).
formstring–10-K or 10-Q. Default 10-K.

NameTypeReqDescription
commoditystringyesNASS commodity name, e.g. CORN, SOYBEANS, WHEAT, CATTLE.
limitinteger–Rows to return, max 100. Default 20.

No output schema declared.

No examples provided.

edgar_search ~146

NameTypeReqDescription
formsstring–Optional comma list of form types, e.g. 10-K,8-K.

Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Official EIA energy figures, newest period first: electricity_price (retail cents per kWh by state and sector), fuel_price (retail gasoline and diesel dollars per gallon by region), grid_demand (hourly demand and day-ahead forecast by balancing authority). Costs $0.05 per call.

NameTypeReqDescription
limitinteger–Rows to return, max 100. Default 10.
regionstring–Balancing-authority code such as CISO or ERCO, for grid_demand.
sectorstring–RES, COM, IND, TRA or ALL, for electricity_price. Default RES.
seriesstringyesWhich EIA series to read.
statestring–Two-letter state code, for electricity_price.

No output schema declared.

No examples provided.

evm_balance ~81

Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Native balance of any 0x address with block height, from public RPC. Costs $0.01 per call.

No examples provided.

filing_events ~160

A company's 8-K filings parsed into material events with decoded item codes: executive departures (5.02), restatements (4.02), acquisitions (2.01), cybersecurity incidents (1.05), and the rest. eventDate is when it happened, filedAt when it was disclosed. Costs $0.05 per call.

NameTypeReqDescription
companystringyesTicker symbol (e.g. AAPL) or SEC CIK number (e.g. 320193).

itemstring–Optional item-code filter, e.g. 5.02.
limitinteger–Events to return, max 25. Default 10.

No output schema declared.

No examples provided.

filing_section ~314

Pull a single numbered item out of a 10-K or 10-Q as clean text: risk factors (1A), MD&A (7), business (1), and the rest. Saves you fetching a multi-megabyte HTML document and finding the section yourself. Pin an exact filing with `accession`; without it you get the most recent filing of that form, and the response warns if a later amendment exists. Failure mode: if a filing's layout hides the item heading, the call errors clearly instead of returning a guessed section. Every response carries accessionNumber, filingDate, source URL, and parserVersion; accuracy is measured on a public golden set (signalnodus.ai/eval). Large cold filings can take several seconds to fetch and parse. Costs $0.05 per call. No subscription: present a credit key or a machine payment.

Common questions

What is the Signal Nodus SEC Filings MCP server?

Signal Nodus SEC Filings is an MCP server listed in the public MCP registry as ai.signalnodus/sec-filings. Amendment-safe 10-K/10-Q section diffs, claim checks vs XBRL, 8-K events. Accuracy published. This page covers its hosted endpoint (https://mcp.signalnodus.ai/).

Is the Signal Nodus SEC Filings MCP server safe to use?

Signal Nodus SEC Filings scores 25 out of 100 on VerifyMCP. 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 Signal Nodus SEC Filings MCP server expose?

Signal Nodus SEC Filings exposes 31 tools: lookup_company, recent_filings, latest_filings, filing_section, compare_filings, and 26 more. Their descriptions and schemas cost roughly 4,242 tokens of context every time the server is loaded.

Does the Signal Nodus SEC Filings MCP server require authentication?

Its publisher declares no required credentials for Signal Nodus SEC Filings. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

Is the Signal Nodus SEC Filings MCP server still maintained?

Signal Nodus SEC Filings 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.
