## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-20.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 24 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 76/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 3057 tokens (~127/item across 24 items; 24 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (24)

### `lookup_company` (~107 tokens)

Look up a 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.

Input parameters:

- `company` (string, required): Ticker symbol (e.g. AAPL) or SEC CIK number (e.g. 320193).

### `recent_filings` (~202 tokens)

Recent SEC 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.

Input parameters:

- `company` (string, required): Ticker symbol (e.g. AAPL) or SEC CIK number (e.g. 320193).
- `form` (string): Optional exact form type filter, e.g. 10-K, 10-Q, 8-K, 4.
- `limit` (integer): How many filings to return (1-50, default 10).

### `company_financials` (~130 tokens)

Reported financial figures

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.

Input parameters:

- `company` (string, required): Ticker symbol (e.g. AAPL) or SEC CIK number (e.g. 320193).
- `concept` (string, required): US-GAAP concept name.

### `filing_section` (~244 tokens)

Extract one section of a filing

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.

Input parameters:

- `accession` (string): Exact accession number to pin, e.g. 0000320193-26-000020. Strongly recommended for anything reproducible.
- `company` (string, required): Ticker symbol (e.g. AAPL) or SEC CIK number (e.g. 320193).
- `form` (string): 10-K or 10-Q. Default 10-K.
- `item` (string): Item number, e.g. 1A, 7, 7A. Call with item omitted to list what this filing has.
- `max_chars` (integer): Truncate the section. Default 50000.

### `compare_filings` (~215 tokens)

Diff a section across two filings

Compare the same item between two filings of a company and return what changed: added and removed passages plus a change ratio. This is the year-over-year risk factor or MD&A comparison, done for you. 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.

Input parameters:

- `company` (string, required): Ticker symbol (e.g. AAPL) or SEC CIK number (e.g. 320193).
- `form` (string): 10-K or 10-Q. Default 10-K.
- `from_accession` (string): Older filing to compare from.
- `item` (string): Item to compare, e.g. 1A for risk factors. Default 1A.
- `max_passages` (integer): Cap on added/removed passages returned. Default 40.
- `to_accession` (string): Newer filing to compare to.

### `who_holds` (~111 tokens)

Which institutions hold a stock

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.

Input parameters:

- `limit` (integer): Managers to return. Default 25.

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.

Input parameters:

- `company` (string, required): Manager name or CIK, e.g. Berkshire Hathaway.
- `top` (integer): Positions to return. Default 20.

### `insider_trades` (~115 tokens)

Parsed insider trades (Form 4)

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.

Input parameters:

- `company` (string, required): Ticker symbol (e.g. AAPL) or SEC CIK number (e.g. 320193).
- `limit` (integer): Form 4 filings to parse. Default 5.

### `latest_filings` (~130 tokens)

Latest filings hitting EDGAR right now

The market-wide feed of filings as they land at the SEC, optionally filtered by form type.
