// key findings
✅
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: FLIP_SUPABASE_SERVICE_KEY, JWT_SECRET, MCP_AUTH_TOKEN
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.
configFLIP_DB_READONLY_URLThe connection string from step 2, using the flip_readonly role
🔐 secretFLIP_SUPABASE_SERVICE_KEYSame page — the legacy service_role key (not the new sb_secret_... format — see note below)
configFLIP_SUPABASE_URLYour flip-tracking Supabase project → Settings → API
🔐 secretJWT_SECRETMake up a long random string
🔐 secretMCP_AUTH_TOKENMake up another random string (a static-token fallback, same pattern as deal-analysis-mcp)
configOAUTH_ISSUERYour deployed Railway URL, e.g. https://flip-database-mcp-production.up.railway.app
Deployment configuration, supplied by whoever hosts the server. Users are not asked for these.

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

4/4 tools missing one or more hints — search_flip_database (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_property_flip_history (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); summarize_flip_metrics (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +1 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.

License file

// 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.
