// key findings
✅
18 tools verified — handlers match their declared behaviour
8 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.
🔐
You'll be asked for 3 credentials: ANTHROPIC_API_KEY, HUBSPOT_ACCESS_TOKEN, MCP_API_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.
🔐 secretANTHROPIC_API_KEY
🔐 secretHUBSPOT_ACCESS_TOKENYour HubSpot private app token
🔐 secretMCP_API_KEYA strong random secret you generate (e.g. openssl rand -hex 32)
Deployment configuration, supplied by whoever hosts the server. Users are not asked for these.

openWorldHint matches behaviour

18 tools claim openWorldHint=false but make outbound HTTP — hubspot_get_company → dynamic (line 50); hubspot_list_companies → /crm/v3/objects/companies (line 72); hubspot_create_company → /crm/v3/objects/companies (line 105)

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.

// 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
