Available components
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. How we score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management10
- Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

get_activist_stakes ~149
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum number of 13D/13G filings to return. Default 20. |

get_company_timeline ~172
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum number of timeline items after merging all form types. Default 50, maximum 300. |

Data delayed 24 hours (known_at); recent filings only.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Maximum number of Form 144 notices to return. Default 20. |

search_insider_events ~395
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.

| 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). |
