Primary-source SEC intelligence for AI agents, delivered over MCP. 27 tools: year-over-year filing diffs, 8-K material events, 13D/13G activist stakes, insider Form 4 trades, 13F institutional holdings, IPO pipeline, full-text EDGAR search since 2001, XBRL financials with numeric claim verification, plus US federal contract awards and lobbying disclosures. Every call is priced per use. Bring a prepaid key, or pay per call with x402 on Base. No signup and no subscription; the lookup_company call is free, so an agent can prove the service before it spends anything.
https://mcp.signalnodus.ai/claude mcp add signal-nodus-sec-filings --transport http https://mcp.signalnodus.ai/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.
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.
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.
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, which changes when the company amends. Costs $0.05 per call. No subscription: present a credit key or a machine payment.
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. Costs $0.50 per call. No subscription: present a credit key or a machine payment.
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.
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.
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.
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.
Native balance of any 0x address with block height, from public RPC. Costs $0.01 per call.
Current gas price in wei and gwei with block height. Costs $0.01 per call.
Status, gas used, effective gas price and log count for a transaction hash. Costs $0.01 per call.
DEX-aggregated price, FDV, market cap and 24h volume for a token contract. Cached 60s; not an oracle. Costs $0.01 per call.
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.
DNS records, SPF presence, registration date and age, registrar, expiry and RDAP status for a hostname, in one call. Costs $0.01 per call.
Top-volume Polymarket markets with implied probabilities, optionally filtered by a question substring. Costs $0.01 per call.
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.
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.
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.
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.
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.
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.
One decision number: how much of a filing item was rewritten year over year, as a percent with a verdict band (routine, typical, elevated, major rewrite). Built on the same sentence-level diff as compare_filings; buy that when you need the passages themselves. Costs $0.10 per call.
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.
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.
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.
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.
