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.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Nodemailer: Message-level raw option bypasses disableFileAccess/disableUrlAccess, enabling arbitrary file read and full-response SSRF in the delivered message
Nodemailer: CRLF injection in Nodemailer List-* header comments allows arbitrary message header injection
Nodemailer: Improper TLS Certificate Validation in OAuth2 Token Fetch Enables Credential Interception
Nodemailer jsonTransport bypasses disableFileAccess and disableUrlAccess during message normalization
Dependencies
8 dependencies, 1 flagged: playwright
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
15/15 tools missing one or more hints — search_products (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_new_arrivals (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_coming_soon (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +12 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.
Descriptions match behaviour
1 tool describes read intent but its handler mutates — check_restocks (line 703: execSync()
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
9/15 tool handlers declare input schemas (60%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 2/15 tool handlers wrap calls in try/catch (13%)
Wrap each tool handler body in try/catch and return a structured error response.
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 — nodemailer@8.0.5 (high), nodemailer@8.0.5 (low)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Tool description accuracy
check_restocks: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
