// 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.
configGOOGLE_APPLICATION_CREDENTIALS1. Service Account Key File (Recommended): Set the environment variable to the path of your service account key file. This is the standard Google Cloud authentication method.
configGOOGLE_CLIENT_EMAIL2. Environment Variables: Set and GOOGLE_PRIVATE_KEY environment variables directly. This is useful for environments where storing a key file is not practical.
configGOOGLE_CLOUD_PROJECTThe server will also use the environment variable if set, otherwise it will attempt to determine the project ID from the authentication credentials.

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

56/56 tools missing one or more hints — gcp-billing-list-accounts (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gcp-billing-get-account-details (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gcp-billing-list-projects (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +53 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.

Tool inputs are validated

45/56 tool handlers declare input schemas (80%)

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

Tool test coverage

38/56 tools referenced in tests (68%)

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

Shell command execution

2 child_process calls — runs shell commands

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.17.0 (high), @modelcontextprotocol/sdk@1.17.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dev dependencies

1 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.

// 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 7 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
