Test it

Using "pricewin-flight-search". Find one-way economy flights from SGN to BKK next Friday for two adults.

Expected outcome:

The results list the cheapest available flights first.
Each option includes airline, flight number, times, duration, stops, and the total fare for two adults.
The response includes only provider links returned by the search.

Using "pricewin-flight-search". Compare return flights from HAN to SIN and highlight practical nonstop choices.

Expected outcome:

Outbound and return options appear under separate headings.
The lowest fare is identified, with a nearby nonstop alternative highlighted when useful.
Any combined estimate is labeled as two separately booked one-way tickets.

Using "pricewin-flight-search". Find business-class flights from Tokyo to Seoul without choosing an airport for me.

Expected outcome:

The assistant asks which Tokyo and Seoul airports to use before starting the search.

Security Audit

High Risk

v1 • 8/16/2026 Open versioned report

Most static alerts are false positives caused by Markdown backticks, JavaScript template literals, or disclosed configuration paths. The installer still modifies several user-level agent configurations and persistently registers a closed-source remote MCP service. Flight searches disclose route and trip details to that service.

Lines analyzed

False positives ignored

Confirmed security concerns (2)

High

install.sh:134-174 SECURITY.md:15-21

Broad Persistent Registration of a Remote MCP Server

The installer registers one closed-source remote MCP endpoint across every detected agent. This creates persistent third-party tool trust beyond a single client.

The installer explicitly discovers six client families and modifies their user configurations. The disclosure confirms that the hosted server implementation is closed source.

Medium

SECURITY.md:15-21 SECURITY.md:40-51

Travel Query Disclosure to a Closed-Source Service

Flight routes, dates, passenger counts, cabin class, and session identifiers leave the machine. Travel plans can be sensitive even without identity or payment data.

The security disclosure identifies the hosted intermediary and lists every transmitted field. It also states that the server code cannot be inspected.

Capability review items (19)

These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

Medium

install.sh:62

Node.js fs operations

const raw = fs.readFileSync(file, 'utf8').trim();

The installer reads an existing agent configuration before merging an MCP entry. The access is intentional but reaches user-owned configuration data.

Medium

install.sh:99

Node.js fs operations

fs.mkdirSync(path.dirname(file), { recursive: true });

The installer creates parent directories for selected agent configurations. This is an intentional filesystem change performed with the invoking user permissions.

Medium

install.sh:100

Node.js fs operations

if (existed && !fs.existsSync(`${file}.bak`)) fs.copyFileSync(file, `${file}.bak`);

The installer copies an existing configuration to a backup before mutation. This creates an additional persistent copy of user configuration data.

Medium

install.sh:101

Node.js fs operations

fs.writeFileSync(file, `${JSON.stringify(config, null, 2)}\n`);

The installer rewrites parsed agent configuration with a remote MCP entry. An incompatible schema or interrupted write could damage user configuration.

Medium

install.sh:62

Synchronous file operations

const raw = fs.readFileSync(file, 'utf8').trim();

A synchronous read loads the complete agent configuration for parsing. The operation is local and intentional, but it accesses user-owned settings.

Medium

install.sh:101

Synchronous file operations

fs.writeFileSync(file, `${JSON.stringify(config, null, 2)}\n`);

A synchronous write replaces the selected agent configuration after merging. The script does not use an atomic temporary-file replacement.

Medium

install.sh:109

Hidden file access

local file="$HOME/.codex/config.toml"

The Codex installer targets the user-level hidden configuration file. Later lines can append a persistent remote MCP server entry to this file.

Medium

install.sh:110

Hidden file access

[ -d "$HOME/.codex" ] || return 1

The installer probes the hidden Codex directory before changing its configuration. This is intentional client discovery in the user home directory.

Medium

install.sh:120

Hidden file access

mkdir -p "$HOME/.codex"

The installer creates the hidden Codex directory before appending configuration. This is a persistent user-home modification.

Medium

install.sh:146

Hidden file access

merge_json "$HOME/.claude.json" mcpServers

The fallback path merges the remote server into the user-level Claude configuration. This intentionally changes persistent agent settings.

Medium

install.sh:148

Hidden file access

elif [ -f "$HOME/.claude.json" ] || [ -d "$HOME/.claude" ]; then

The installer checks hidden Claude paths to detect an installed client. The result controls whether the client configuration is modified.

Medium

install.sh:150

Hidden file access

merge_json "$HOME/.claude.json" mcpServers

The installer merges the remote endpoint into the hidden Claude configuration. This is a persistent modification outside the skill directory.

Medium

install.sh:161

Hidden file access

$HOME/.cursor/mcp.json|url

This path is fed into the installer loop that checks and may rewrite Cursor configuration. The access is intentional and persistent.

Medium

install.sh:162

Hidden file access

$HOME/.codeium/windsurf/mcp_config.json|serverUrl

This path is fed into the installer loop that checks and may rewrite Windsurf configuration. The access is intentional and persistent.

Medium

install.sh:163

Hidden file access

$HOME/.gemini/settings.json|httpUrl

This path is fed into the installer loop that checks and may rewrite Gemini configuration. The access is intentional and persistent.

Medium

install.sh:167

Hidden file access

for vscode_dir in "$HOME/.vscode" "$HOME/Library/Application Support/Code/User" "$HOME/.config/Code/

The installer checks several VS Code user directories and may create an MCP configuration. This extends modification across multiple client installations.

Low

install.sh:20

Hardcoded URL

MCP_URL="${PRICEWIN_MCP_URL:-https://mcp.price.win/mcp}"

The installer persists a default third-party MCP endpoint in detected agent configurations. Future flight queries therefore leave the machine through that service.

Low

install.sh:60

Node.js fs stat operations

if (fs.existsSync(file)) {

The installer checks whether a target agent configuration exists. The check is limited to predefined paths but still inspects the local environment.

Low

install.sh:100

Node.js fs stat operations

if (existed && !fs.existsSync(`${file}.bak`)) fs.copyFileSync(file, `${file}.bak`);

The installer checks for an existing backup before copying configuration data. This is a bounded and intentional filesystem inspection.

Prepare client options

Build a concise shortlist of practical fares before a client selects a provider.

Research business travel

Compare nonstop and shorter schedules against the lowest fare for a planned work trip.

Try These Prompts

Search a one-way flight

Find one-way economy flights from [ORIGIN IATA] to [DESTINATION IATA] on [DATE] for [ADULTS] adults.

Compare a return journey

Search flights from [ORIGIN] to [DESTINATION] on [DEPARTURE DATE], returning [RETURN DATE]. Show the best options for each leg.

Balance price and convenience

Compare business-class flights from [ORIGIN] to [DESTINATION] on [DATE]. Prioritize nonstop options when the price difference is small.

Best Practices

Provide three-letter IATA codes and ask before resolving cities with multiple airports.
Read the returned currency and passenger count before describing any fare.
Recheck availability and price on the provider page before purchase.

Avoid

Do not invent airport codes, fares, provider names, or booking links.
Do not describe independently searched return legs as one quoted round-trip fare.
Do not send names, payment details, or unrelated conversation through free-text search fields.
