// key findings
✅
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 3 credentials: GRAPHQL_INTROSPECTION_TOKEN, GRAPHQL_TOKEN, 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.
configGRAPHQL_API_URLEndpoint used for queries and mutations. Defaults to a public demo API ([countries.trevorblades.com](https://countries.trevorblades.com/graphql)) if unset — replace with your own for real use.
configGRAPHQL_INCLUDE_MUTATIONSSet to false to exclude every mutation field entirely, for a read-only deployment. Default true.
🔐 secretGRAPHQL_INTROSPECTION_TOKENBearer token for schema introspection, if it requires different credentials than execution (e.g. a separate schema registry). Defaults to GRAPHQL_TOKEN if unset.
configGRAPHQL_INTROSPECTION_URL2. If not found, run live introspection against
configGRAPHQL_MAX_RETRIESRetries (0–5) for 429/502/503/504 responses, honoring Retry-After when present. Default 0 (disabled).
configGRAPHQL_MAX_TOOLSMaximum number of query/mutation tools to register. Queries are prioritized over mutations when truncating. Default 128.
🔐 secretGRAPHQL_TOKENBearer token for GraphQL authentication (used for query/mutation execution). Omit for public APIs.
🔐 secretMCP_AUTH_TOKENBearer token required by the hosted /mcp HTTP endpoint when MCP_TRANSPORT=http
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

2/2 tools missing one or more hints — execute_graphql (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_type_details (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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 test coverage

Only 0/2 tools referenced in tests (0%)

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

// 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 3 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
