The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.

// key findings
✅
43 tools verified — handlers match their declared behaviour
23 read-only tools verified — handlers contain no write/delete/exec
✅
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: GUESTY_CLIENT_SECRET, GUESTY_MCP_LICENSE_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

openWorldHint matches behaviour

23 tools claim openWorldHint=false but make outbound HTTP — get_reservations → open-api.guesty.com (line 50); get_listing → open-api.guesty.com (line 50); get_financials → open-api.guesty.com (line 50)

Either flip openWorldHint to true (acknowledging external reach) or refactor the handler to avoid outbound HTTP. If the only network calls are to a known fixed endpoint that you consider part of the tool itself, document that and keep openWorldHint=false; otherwise true is honest.

Tool inputs are validated

22/23 tool handlers declare input schemas (96%)

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

Tool test coverage

Only 5/43 tools referenced in tests (12%)

Write tests that reference each tool by name so every tool has at least one test.

Secrets not logged

5 secret values sent to console.log

Redact or omit secret values from log output.

// 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 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
