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.

get_bash_outputs

Get all bash command outputs from a Jules session. Returns commands executed, their stdout/stderr, and exit codes. Use to understand what shell commands were run.

create_session

Creates a new Jules session or automated run to perform code tasks. If repo and branch are omitted, creates a "repoless" session where the user provides their own context in the prompt and Jules will perform code tasks based on that context instead of a GitHub repo.

list_sessions

List recent Jules sessions with pagination support.

query_cache

Query the LOCAL CACHE of sessions and activities. Returns only previously synced data (fast, but may be stale). To ensure fresh data: call jules_sync first, then jules_select. Best for searching across multiple sessions or filtering by type/state.

get_code_review_context
send_reply_to_session

Interacts with an active Jules session (approving plans or sending messages).

get_session_state

Get the current status of a Jules session. Acts as a dashboard to determine if Jules is busy, waiting, or failed. RETURNS: id, status, url, title, prompt, pr (if created), lastActivity, lastAgentMessage (if any), pendingPlan (if awaiting approval) STATUS (use this to decide what action to take): -…

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

8/8 tools missing one or more hints — get_bash_outputs (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_session (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_sessions (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 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@1.0.0 (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.
