Install from
The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
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.
list_allowed_aliasesList the whitelisted email aliases this server exposes, and whether each is a registered Gmail send-as alias (i.e. can be used as from_alias when sending or drafting).
search_emailsSearch messages involving the whitelisted aliases. Only mail sent from or received by a whitelisted alias is visible; other mail does not exist as far as this server is concerned.
get_messageFetch one message (headers, plain-text body, attachment metadata) by Gmail message ID.
get_threadFetch a conversation thread. Returns only the messages that involve a whitelisted alias (headers + snippet; use get_message for full bodies).
get_attachmentDownload one attachment (base64) from an accessible message. Size-capped by server config.
send_emailSend a plain-text email from a whitelisted alias. Supports replying into an existing thread.
create_draftCreate a Gmail draft from a whitelisted alias for human review. Supports replying into an existing thread.
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
7/7 tools missing one or more hints — list_allowed_aliases (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_emails (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_message (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 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.).
Tool test coverage
Only 1/7 tools referenced in tests (14%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
1/5 production deps stale: email-addresses@2022-06-16 (4.1y)
