// key findings
⚠️
Known vulnerabilities in dependencies: 3 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
🔐
You'll be asked for 2 credentials: SIGNALSCOPE_API_KEY, SIGNALSCOPE_WALLET_PRIVATE_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// tools this server exposes22 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.

search_tickers

Search SignalScope tickers by symbol or partial name. Free endpoint — no API key required. Returns up to 8 matches with aiScore, opportunityScore (null if not yet validated), stage, and price.

get_methodology

Get the SignalScope platform methodology — how signals are harvested, scored, filtered, and staged. Free endpoint — no API key required.

get_trending

Get trending breakout tickers — symbols appearing in 2+ scans within the last 30 days, with aiScore, opportunityScore, performance, and trend (rising/falling/stable from score history). Paid: API key (subscriber) or x402 ($0.01). summary.avgScore is mean aiScore only.

get_ticker

Get the latest validated ticker row plus raw signals. Includes opportunityScore (early-mover rank) and aiScore (evidence confidence — not expected returns), stage, fundamentals, P&D fields, cached report fields if present, and signals[]. Paid: API key or x402 ($0.005).

get_ticker_history

Get historical scan appearances for a ticker (up to ~90 completed scans), ordered by scan time. Each row: scanId, startedAt, aiScore, stage, price, signalCount, sourceCount, recommendation. No server-side pagination — the API returns the full list. Paid: API key or x402 ($0.005).

get_ticker_performance

Get price performance data for a ticker — 1-day, 3-day, 7-day, and 30-day returns tracked from the time of signal detection. Requires API key or x402 payment ($0.005).

get_ticker_related

Co-occurring scan symbols ranked by Pearson price correlation vs target (correlationScore). latestAiScore is AI confidence only; use get_ticker for opportunityScore. API key or x402 ($0.005).

get_ticker_network

Price-correlation graph: nodes from co-occurrence or top trending; edges above minCorrelation (0–1). Omit symbol for trending-based graph. API key or x402 ($0.01).

generate_report

AI report + trade setup. Not available via x-api-key (403). Use x402 ($0.05) or website; Pro to generate new reports; cached may load when signed in. POST.

list_scans

List harvest scans (paginated). Public. Paid ticker routes still need API key or x402.

get_scan

One scan with validated tickers (aiScore desc, opportunityScore tiebreak). Public.

get_signals

Raw signals for a scan (max 200), by source count then velocity. Public.

list_portfolio

List all portfolio positions for the authenticated user — open and closed positions with entry price, shares, notes, and P&L. Requires API key.

add_position

Add a new position to the portfolio. Requires API key.

update_position

Update position: notes, entryPrice, shares, or close (status CLOSED + closePrice). API key required.

delete_position

Permanently delete a portfolio position. This action cannot be undone. Requires API key.

get_portfolio_performance

Get platform-wide portfolio performance statistics — win rate, average return, and median return across all tracked positions, broken down by AI score range, opportunity score range, and weekly cohorts. Requires API key.

list_watchlist

List all watchlist items for the authenticated user, enriched with latest ticker data, signal stage, AI score, and performance metrics. Requires API key.

add_to_watchlist

Add a ticker symbol to the watchlist. Idempotent — safe to call even if already on watchlist. Requires API key.

remove_from_watchlist

Remove a ticker symbol from the watchlist. Requires API key.

get_prices

Current prices for up to 50 symbols (5-minute cache). Auth optional.

get_platform_stats

Platform stats: completed scans, summed signal counts, distinct validated tickers. Public (rate-limited).

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

22/22 tools missing one or more hints — search_tickers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_methodology (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_trending (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +19 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

13/22 tool handlers declare input schemas (59%)

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@1.10.1 (high), @modelcontextprotocol/sdk@1.10.1 (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.
