These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

query

Fetch Census data. Returns structured JSON with column headers. Common datasets: acs/acs1 (American Community Survey 1-year), acs/acs5 (5-year), dec/pl (Decennial Census).

list_datasets

List available Census datasets for a given year

list_variables

List variables available in a dataset. Returns variable codes, labels, and concepts.

list_geographies

List available geographic levels for a dataset

get_fips

Get FIPS codes for a geography level. Useful for finding state/county codes.

// known CVEs in dependencies1 high

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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

5/5 tools missing one or more hints — query (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_datasets (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_variables (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +2 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

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.25.3 (high)

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

// 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 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
