// tools this server exposes16 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

get_transactions

Search SEC Form 4 insider transactions. Filter by ticker, insider, transaction type, date range, and more. Use exclude_10b5=true for discretionary-only signal analysis.

get_recent_filings

Get the most recent SEC Form 4 filings, optionally filtered by ticker.

get_filing

Get a single Form 4 filing by its SEC accession number.

get_insider_profile

Get an insider profile by CIK — name, title, role flags (director/officer/10pct owner).

get_insider_transactions

Get all Form 4 transactions for a specific insider by their CIK.

get_company_overview

Get company profile — name, CIK, SIC sector, state of incorporation, website, filing counts.

get_company_insiders

List all insiders who have filed Form 4s for a company.

get_signals

Get cluster buy/sell signals — multiple insiders at the same company transacting in the same direction within a short window. Excludes 10b5-1 plan trades automatically (no scraping-based tool does this). Requires Business plan.

get_form144

List Form 144 notice-of-proposed-sale filings. Insiders disclose intent to sell ~2 days before the actual Form 4 sale lands — early signal on discretionary vs pre-scheduled sales. Filter by ticker, insider name, date range, or exclude 10b5-1 plans. Requires Business plan.

get_holdings

List institutional positions from Form 13F-HR filings. Filter by ticker (CUSIP→ticker resolved automatically), CUSIP, manager CIK, quarter, or minimum position value. Use this to find "who owns NVDA" or "which managers added to AAPL last quarter". Requires Business plan.

get_managers

Browse the institutional manager index — each manager with their latest 13F-HR filing and AUM. Filter by name (partial match — "Berkshire" returns Berkshire Hathaway) or minimum AUM. Pair with get_holdings to see what a given manager owns. Requires Business plan.

get_sentiment

Get the monthly insider-sentiment score for a ticker (MSPR-style, -100 to +100). Automatically excludes 10b5-1 plan trades — the score reflects actual insider conviction, not pre-scheduled dispositions. Requires Business plan.

get_insider_career_summary

Get an aggregate career rollup for a single insider by CIK: first/last transaction, total bought/sold/net, top companies, transaction-code breakdown, 10b5-1 plan split, post-trade return averages. Requires Pro plan.

check_usage

Check current API key usage stats — plan name, requests today, daily limit, all-time request count.

verify_setup

validates your Form4API key + connectivity and returns a green check or exact fix steps; run this first if other tools fail

research_company

One call: a bundled, AI-ready insider-research context for a ticker — company profile, recent insider transactions, cluster signals, sentiment, and a computed buy/sell summary. Use this FIRST when researching a company's insider activity; it replaces several separate calls. Note: makes multiple API …

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

16/16 tools missing one or more hints — get_transactions (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_recent_filings (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_filing (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +13 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool inputs are validated

Only 0/16 tool handlers declare input schemas (0%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail

The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.

// improvement guidance — verified publishers only

We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
