// tools this server exposes12 tools

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.

create_pair

Create a new pair. The creator becomes owner. Returns pairId and the first invite token.

invite_member

Generate an invite token. Only an active member of the pair may invite. Caps pending invites per pair.

accept_invite

Redeem an invite token to join a pair. Idempotent rejection on double-accept and expired tokens.

list_members

List all active members of a pair (excludes members who left or were kicked).

set_member_preferences

Set a per-user preference (e.g. allergy, taste). Only readable by the same member via get_member_constraints.

get_member_constraints

Read per-user state. A member can only read their own state; cross-member reads are not exposed.

get_shared_state

Read shared state for the entire pair (default namespace). All members can read.

set_shared_state

Write shared state. Bi-temporal: previous active row gets valid_to, new row appended.

resolve_conflicts

Resolve pending conflicts using LWW (default) or manual. Idempotent: re-running on a clean state is a no-op.

kick_member

Remove a member from a pair. Only the owner may kick. Owner cannot kick themselves.

leave_pair

Voluntarily leave a pair. Sets left_at; shared state remains for other members.

forget_member

DSGVO Art. 17 right-to-erasure: hard-delete the member's per-user state (allergies, dietary preferences, etc.) and null their display name. The membership trace (left_at marker) is retained for audit. Idempotent.

Tool annotations

12/24 tools have annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

24/24 tools missing one or more hints — create_pair (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); invite_member (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); accept_invite (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +21 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.).

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.20.0 (high), @modelcontextprotocol/sdk@1.20.0 (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 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
