All four hints declared on every tool

4/4 tools missing one or more hints — selvage_search (missing: destructiveHint, idempotentHint, openWorldHint); selvage_who_knows (missing: destructiveHint, idempotentHint, openWorldHint); selvage_list_sources (missing: 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.

Tool test coverage

Only 0/4 tools referenced in tests (0%)

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

Secrets not logged

1 secret value sent to error

// 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.
