Capabilities
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
evm
evm_balance
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Native balance of any 0x address with block height, from public RPC.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.
evm_gas
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Current gas price in wei and gwei with block height. Costs $0.01 per call.
evm_receipt
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Status, gas used, effective gas price and log count for a transaction hash. Costs $0.01 per call.
filing
filing_events
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.
filing_section
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.
token
token_price
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): DEX-aggregated price, FDV, market cap and 24h volume for a token contract. Cached 60s; not an oracle. Costs $0.01 per call.
token_report
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): One-call market data for an ERC-20 token: price, 24h change, FDV, market cap, 24h volume, supply, pool count, deepest pool liquidity, and factual risk flags (low liquidity, thin volume). GeckoTerminal aggregated DEX data. Not an oracle, not financial advice. Costs $0.10 per call.
activist
activist_stakes
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.
cftc
cftc_positioning
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.
company
company_financials
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.
compare
compare_filings
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.
crop
crop_data
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Official USDA NASS estimates from Quick Stats: yields, production, area planted and harvested, stocks, and prices received, national or by state. Values are as published, including NASS's own suppression markers. Costs $0.05 per call.
domain
domain_report
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): DNS records, SPF presence, registration date and age, registrar, expiry and RDAP status for a hostname, in one call. Costs $0.01 per call.
edgar
edgar_search
Exact-phrase full-text search over every EDGAR filing since 2001. Returns the company, form, date, and accession number of each hit, ready to feed into filing_section or compare_filings. Costs $0.01 per call.
energy
energy_data
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.
gas
gas_optimizer
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Live network fee across Base, Arbitrum, and Ethereum, expressed as the USD cost of a standard native transfer so chains compare on money, with the cheapest chain named. Network fee only, not a route or swap quote. Costs $0.05 per call.
government
government_contracts
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Federal prime contract awards to a company from USAspending.gov, largest first: award id, amount, agency, and period. Recipient match is by name text. Costs $0.05 per call.
insider
insider_trades
A company's latest Form 4 filings parsed into data: who traded, their role, buy or sell, shares, price, and holdings after. The free EDGAR servers list Form 4s; this one reads them. Every filing pinned by accession number. Costs $0.05 per call.
institutional
institutional_holdings
An institutional manager's latest 13F-HR parsed and aggregated: top positions by value with shares, CUSIP, and share of portfolio. Works on managers (Berkshire, Bridgewater...), not operating companies. Pinned by accession number. Costs $0.05 per call.
ipo
ipo_pipeline
New S-1 and F-1 registration statements as they land at EDGAR, market-wide and newest first: the earliest public signal of a US IPO. Costs $0.01 per call.
latest
latest_filings
The market-wide feed of filings as they land at the SEC, optionally filtered by form type. Built for monitoring agents that poll: the answer is cached for 60 seconds upstream, includes 8-K item codes so a watcher can filter on events, and every entry carries its accession number for pinning. Costs $0.01 per call.
lobbying
lobbying
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): US Senate LDA lobbying disclosures for a client company, newest first: registrant, reported income or in-house expenses, and issue areas. Costs $0.05 per call.
lookup
lookup_company
Resolve a ticker or CIK to a company's canonical SEC identity: legal name, CIK, industry classification, tickers, and exchanges. Use this first when you only have a ticker and need the CIK for other calls. US SEC registrants only. Free: no key and no payment needed. Use it to verify the service before paying.
prediction
prediction_markets
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Top-volume Polymarket markets with implied probabilities, optionally filtered by a question substring. Costs $0.01 per call.
rate
fx_rate
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): ECB reference rates from one base currency to up to ten targets, ISO 4217. Daily fix, not a tradable quote. Costs $0.01 per call.
recent
recent_filings
List a company's most recent SEC filings with form type, dates, accession number, and a direct document URL. Optionally filter to one form type (10-K, 10-Q, 8-K, 4, S-1...). Covers EDGAR's recent-filings index, which holds roughly the last 1000 filings; older history is not searched, and the response says so when it exists. This is the canonical filing record, not commentary about it. Costs $0.01 per call. No subscription: present a credit key or a machine payment.
rewrite
rewrite_ratio
Mechanical rewrite ratio of a filing item year over year: added sentences divided by total sentences in the newer section, as a percent, with a magnitude band. This measures editing activity in the text, not risk and not exposure; a lightly reworded sentence counts as one removal plus one addition. Built on the same sentence-level diff as compare_filings; buy that when you need the passages themselves. Formerly named risk_churn_score, which still answers. Costs $0.10 per call.
trade
trade_flows
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Monthly US customs-reported trade value in dollars by trading partner for one HS chapter, from the Census international trade series. Exports are total value, imports are general imports. Costs $0.05 per call.
verify
verify_financial_claim
Deterministic check of a numeric claim against the company's own XBRL as filed with the SEC. Returns supported, contradicted, or unverifiable, with the as-reported value and the accession number to cite. Costs $0.10 per call.
who
who_holds
Every 13F manager whose latest information table names the company: manager, CIK, filing date, accession number, plus the total count of reporting managers. The inverse of institutional_holdings; chain them to walk from a ticker to full parsed portfolios. Costs $0.05 per call.
x402
x402_audit
Experimental (outside the core SEC path; not covered by the published accuracy eval, may change or be withdrawn): Inspect one public HTTPS x402 endpoint and report the 402 challenge it returns to an anonymous caller: HTTP status, payment rails (scheme, network, asset, recipient), WWW-Authenticate header, Bazaar discovery extension, and a pass/fail checklist with a health verdict. No payment is signed or submitted. Costs $0.10 per call.

Signal Nodus SEC Filings — questions
Answers built from our own checks of this server.
What can Signal Nodus SEC Filings do?
It exposes 31 tools, read directly from the server on our last check. Among them: activist_stakes, cftc_positioning, company_financials, compare_filings, crop_data, domain_report and 25 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is Signal Nodus SEC Filings mostly used for?
Its tools cluster around evm, token and filing. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Signal Nodus SEC Filings working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 134 ms. The bar chart above shows every period we have measured.
Did Signal Nodus SEC Filings ever remove tools?
Yes. risk_churn_score is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
The registry lists Signal Nodus SEC Filings as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Signal Nodus SEC Filings?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Signal Nodus SEC Filings need an API key?
No. Signal Nodus SEC Filings completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 31 of them are readable on this page. This is what we observed, not what the docs claim.
Is Signal Nodus SEC Filings open source?
The code is open source: it is published under the MIT licence, written in JavaScript, 1 stars on GitHub and 2 open issues. The licence covers the code in the repository, not the hosted service at mcp.signalnodus.ai, which runs on its operator's own terms.
