## 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 2026-08-17.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 66/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1062 tokens (~265/item across 4 items; 4 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `search_insider_events` (~395 tokens)

Search interpreted insider-trading events from SEC Form 4 filings. Each event classifies raw filing rows into economic meaning (OPEN_MARKET_BUY vs EQUITY_AWARD vs TAX_WITHHOLDING_ONLY etc.), separating discretionary trades from compensation noise. Supports filtering by ticker, event type, minimum USD value, and time, with cursor pagination. Form 4 only - for 13D/G stakes or Form 144 sale notices use get_activist_stakes, get_sale_notices, or get_company_timeline. Data delayed 24 hours (known_at); history ~1 month; no price-derived fields.

Input parameters:

- `cursor`: Opaque pagination cursor — pass the next_cursor value from the previous response.
- `event_type`: Filter by interpreted event type. One of: OPEN_MARKET_BUY, OPEN_MARKET_SELL, PLANNED_10B5_1_SELL, OPTION_EXERCISE_HOLD, OPTION_EXERCISE_PARTIAL_SELL, OPTION_EXERCISE_FULL_SELL, TAX_WITHHOLDING_ONLY,…
- `limit` (integer): Maximum number of events to return. Default 20, maximum 200.
- `min_value`: Minimum trade value in USD (reported shares × reported price per share).
- `since`: Only return events recorded at or after this ISO 8601 timestamp (e.g. 2026-08-01T00:00:00Z). Compares against recorded_at — useful for incremental sync.
- `ticker`: Stock ticker symbol to filter by, e.g. AAPL or TSLA. Omit to search across all companies.

Output parameters:

- `result` (object)

### `get_company_timeline` (~172 tokens)

Get one merged, time-ordered feed of SEC insider activity for a company: Form 4 events, Schedule 13D/13G stake filings, and Form 144 sale notices, distinguished by the source_form field (form4 | sc13 | form144). The limit applies after merging, so companies with heavy Form 4 activity can crowd out 13D/G and 144 rows - use the dedicated tools for those. Unknown tickers fail with an error (404). Data delayed 24 hours (known_at); no price-derived fields.

Input parameters:

- `limit` (integer): Maximum number of timeline items after merging all form types. Default 50, maximum 300.
- `ticker` (string, required): Stock ticker symbol of the company (issuer), e.g. AAPL or TSLA. Required.

Output parameters:

- `result` (object)

### `get_activist_stakes` (~149 tokens)

Get Schedule 13D/13G beneficial-ownership filings (activist and 5%+ large-holder stakes) for one company - ticker is required. Returns one row per filing with filer names and the maximum reported percent of class; detailed item narrative text is not included. event_revision is always null for these forms (a fact of the form, not missing data). Data delayed 24 hours (known_at); recent filings only.

Input parameters:

- `limit` (integer): Maximum number of 13D/13G filings to return. Default 20.
- `ticker` (string, required): Stock ticker symbol of the company (issuer), e.g. AAPL or TSLA. Required.

Output parameters:

- `result` (object)

### `get_sale_notices` (~133 tokens)

Get Form 144 notices of proposed insider sales for one company - ticker is required. shares_to_sell and aggregate_market_value are as-filed intentions announced before the sale, not executed trades - the matching Form 4 sale, if any, typically follows about a day later. event_revision is always null for this form. Data delayed 24 hours (known_at); recent filings only.

Input parameters:

- `limit` (integer): Maximum number of Form 144 notices to return. Default 20.
- `ticker` (string, required): Stock ticker symbol of the company (issuer), e.g. AAPL or TSLA. Required.

Output parameters:

- `result` (object)
