Overview

AI-generated overview

Remote MCP server giving assistants SEC EDGAR company financials, filings, peer benchmarks, screening and factor scores for US public companies.

What you can do
  • Look up companies by ticker, CIK or name, then pull annual financial statements, raw XBRL facts and SEC filing indexes with sec.gov links.
  • Screen US public companies by financial criteria and compare one company against its industry cohort.
  • Benchmark metrics by industry and revenue size, and run curated market-wide analyses such as top companies, movers and sector landscapes.
  • Score companies with Buffett-style quality and value scans, academic fundamental scores, insider activity, institutional ownership and short-volume pressure.
  • Rank companies by composite factor score or return a single company's factor scorecard.
When to use it
Useful when an assistant needs to answer questions about US public company fundamentals, filings, peer comparisons or value and quality screens, and you would rather call a hosted API than parse EDGAR yourself.
Requirements
A remote streamable HTTP endpoint; no local package. Paid tools need an X-API-Key header obtained by email, or per-call x402 payment in USDC on Base. Without a key only the free list_insights tool works.
Before you install
Paid tools cost money per call, either prepaid via the X-API-Key header or through x402 USDC payments on Base, so usage can spend funds. The API key is a secret sent as a header. Outputs are research and screening signals, not investment advice, and some data lags (13F filings up to 45 days, daily short volume rather than short interest).

Installation

In SourceWeft

  1. Open SEC Fundamentals API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.multyplylabs%2Fsec-fundamentals/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

lookup_company

Look Up Company CIK

Find a company's SEC CIK from its ticker, CIK or name. Every company tool takes a cik, so call this first when you only have a ticker (AAPL) or a name (apple). Returns up to limit matches, best first (exact ticker, exact CIK, name prefix, name contains; within each, companies with tickers before other filers such as individuals), each with cik, name, tickers, sic and sic_description; no match is an empty list, not an error. Free: no API key or payment needed.

Parameterslimitqueryrequired

company_financials

Company Annual Financials

Annual financial statements for one company, one row per fiscal year: income statement, balance sheet and cash flow lines plus ratios (gross_margin, operating_margin, roe, roa, fcf, debt_to_equity, ...). Use it for a known company's history; use company_facts for individual reported values and quarterly periods, compare_to_peers to benchmark it against its industry, and screen_companies to find companies by criteria. Cost: $0.02 per call; unpaid calls return a payment-required error.

Parameterscikrequiredfy_tofy_from

company_facts

Company XBRL Facts

Raw normalized XBRL facts for one company as reported in its SEC filings, newest first: concept, value, unit, period_start and period_end, fiscal_year, fiscal_period, form, filed date and data-quality flags. Use it for individual reported values, quarterly figures or filing provenance; use company_financials for clean annual statements and ratios. Cost: $0.01 per call; unpaid calls return a payment-required error.

Parameterscikrequiredlimitconceptfy_from

company_filings

Company SEC Filings

SEC filing index for one company, newest first: form, filing date, report period, accession number, 8-K item codes and a direct sec.gov document_url. Use it to find or cite a specific 10-K, 10-Q, 8-K or Form 4; use company_facts or company_financials for the numbers in the filings. Cost: $0.005 per call; unpaid calls return a payment-required error.

Parameterscikrequiredformlimit

industry_aggregate

Industry Benchmark Percentiles

Benchmark percentiles (p10, p25, median, p75, p90, plus mean and company count n) for one financial metric, per fiscal year, 2-digit SIC industry group and revenue size bucket. Use it for questions like "what is the median gross margin of large software companies?"; use compare_to_peers to place one company in its cohort and market_insight (sector_landscape) for margin medians across every industry. Cost: $0.05 per call; unpaid calls return a payment-required error.

Parametersfysizemetricrequiredindustry

screen_companies

Screen Companies by Financials

Screen US public companies for one fiscal year by financial criteria and return the matches with their name, tickers, industry and metrics, largest revenue first. Use it to discover companies; use company_financials for one known company's history and industry_aggregate for cohort benchmarks. Cost: $0.10 per call; unpaid calls return a payment-required error.

Parametersfyrequiredlimitfiltersrequired

compare_to_peers

Compare Company to Industry Peers

One company's metrics for a fiscal year next to its industry cohort: the percentiles of every metric for each revenue size bucket in its 2-digit SIC group. Use it to judge whether a company's margins, returns or leverage are above or below sector norms; use industry_aggregate for a cohort without a specific company. Cost: $0.05 per call; unpaid calls return a payment-required error.

Parametersfyrequiredcikrequired

list_insights

List Curated Insights

Catalog of the curated market-wide analyses: each one's name, path, description, parameters with defaults, and price. Call it before market_insight or standard_score to choose an analysis and its parameters. Free: no API key or payment needed.

Takes no parameters.

market_insight

Market-Wide Insight

Curated analysis computed live across all US public companies, chosen by name: top_companies (rank by a metric, optionally within an industry), movers (largest change in a metric between fy_from and fy_to), sector_landscape (margin medians per industry), metric_trend (yearly sum, median or mean of a metric), capital_returns (buybacks vs dividends by size bucket) or filing_velocity (monthly filing counts for a form type). Each parameter's description says which analyses read it; the response reports the fiscal year(s) used. Use screen_companies for your own criteria and standard_score for F-Score, Z-Score and similar scores. Cost: $0.15 per call; unpaid calls return a payment-required error.

buffett_scan

Buffett Quality Scan

Rank US public companies by Quality Score (0-100) over a 10-year window from five components: return on invested capital (30 points, blended 60/40 with the company's industry percentile), durability through the cycle (20), cash conversion (20), balance-sheet strength (15) and capital discipline (15). Every component is explainable from the returned row (roic_median, fcf_conversion, net_debt_to_ebit, ...); a component with no usable data is dropped and the rest renormalized. Companies that stopped filing (4,313), have fewer than five fiscal years on file (1,702), lack the tags to measure returns on capital in enough of those years -- missing EBIT tags, or an unclassified balance sheet, common among homebuilders and industrials with captive finance arms (1,612) -- or are balance-sheet financials (banks, insurers, REITs; 1,539) are not scored and do not appear: 2,885 of 12,051 companies (roughly a quarter of all filers, ~37% of active ones) are scored today. Use it for price-independent quality; use buffett_value to add valuation. Methodology v3; heuristic screen, not investment advice. Cost: $0.25 per call; unpaid calls return a payment-required error.

Parametersfylimitindustrymin_scoremin_revenueexclude_foreign

buffett_value

Buffett Value Scan

Find high-quality US public companies trading below intrinsic value: the Quality Score (see buffett_scan) combined with a value score from the previous close (FCF yield, 10-year owner-earnings DCF margin of safety, P/E), ranked by combined_score, the mean of the two (0-100 each). Rows also carry market cap, owner-earnings yield and intrinsic value. Use buffett_scan for quality alone; it needs no price data. Foreign private issuers (20-F filers, e.g. Chinese ADRs) are excluded by default: they screen cheap for structural reasons fundamentals cannot see. Methodology v3; heuristic screen, not investment advice. Cost: $0.25 per call; unpaid calls return a payment-required error.

Parametersfylimitindustrymin_scoremin_revenueexclude_foreignmin_margin_of_safety

standard_score

Standard Fundamental Scores

Academic fundamental scores across US public companies, chosen by name: piotroski (F-Score 0-9, financial strength), altman_z (bankruptcy-risk zones), beneish_m (elevated M-Score: an accounting-quality screen, not evidence of manipulation), magic_formula (Greenblatt rank on earnings yield and return on capital) or accruals (Sloan earnings quality). Each company is scored on its own latest fiscal year (fiscal_year per row); fy selects the cohort whose latest scored year is fy -- it does not re-score companies on an earlier year. Use company_signal for one company's quality, value and sentiment factors together. Peer-reviewed formulas; not investment advice. Cost: $0.15 per call; unpaid calls return a payment-required error.

Parametersfynamerequiredzonelimitworstmin_scoremin_revenueflagged_onlyexclude_foreign

insider_activity

Company Insider Trades (Form 4)

Insider (Form 4) transactions for one company over the trailing months, plus a summary: open-market buys vs sales, distinct buyers and net dollar value, with 10b5-1 plan flags. Cluster buying by officers and directors is a studied positive signal. Use company_signal for insider conviction scored alongside other factors. Not investment advice. Cost: $0.02 per call; unpaid calls return a payment-required error.

Parameterscikrequiredmonths

institutional_ownership

Company Institutional Ownership (13F)

13F institutional ownership snapshot for one company: number of holders, aggregate shares and value, and quarter-over-quarter change (accumulating vs trimming). 13F filings lag the quarter by up to 45 days and show long positions only. Use company_signal for institutional positioning scored alongside other factors. Not investment advice. Cost: $0.02 per call; unpaid calls return a payment-required error.

Parameterscikrequired

short_pressure

Company Short-Selling Pressure

Short-selling pressure for one company: the FINRA daily short-volume ratio (short volume / total volume) over about 20 trading days, a bearish-sentiment proxy. This is daily short-sale volume, not bi-monthly short interest. Use company_signal for short sentiment scored alongside other factors. Not investment advice. Cost: $0.02 per call; unpaid calls return a payment-required error.

Parameterscikrequired

company_signal

Company Factor Scorecard

Composite factor scorecard for one company: quality (Piotroski, Altman, accruals), value (owner-earnings DCF), insider conviction (Form 4 buying as bps of market cap), institutional positioning (13F) and short sentiment, each 0-100, plus a renormalized composite_score and coverage (the share of factors present). Also returns institutional ownership %, insider buy intensity, short-to-ADV and governance flags (Form 4 latency, Item 4.02 restatements, stale fundamentals). Use top_signals to rank every company by the same composite. RESEARCH SIGNAL, NOT INVESTMENT ADVICE. Cost: $0.05 per call; unpaid calls return a payment-required error.

Parameterscikrequiredweights

top_signals

Top Companies by Factor Score

Rank US public companies by composite factor score (quality, value, insider, institutional and short-sentiment factors, each 0-100), highest first, with each company's factor scores, coverage, and restatement and stale-fundamentals flags. Use company_signal for one company's full scorecard. RESEARCH SIGNAL, NOT INVESTMENT ADVICE. Cost: $0.25 per call; unpaid calls return a payment-required error.
