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.
search_ticketsSearch direct RZD routes by station name/code and departure date.
search_full_compartmentsFind compartments whose places are all free, over an inclusive date range of at most 31 days. A match is confirmed only when the carriage response lists the requested places inside one compartment; carriages with enough free places but no such confirmation are returned as candidates. Dates the scan …
find_stationsFind station candidates, including synonym matches.
get_carriagesGet carriage and seat availability details for a train.
get_train_availabilityGet dates with available trains for a direction.
get_minimal_pricesGet the minimum published prices from a selected date.
get_car_schemeGet carriage scheme metadata, including public links to the scheme drawing. Set include_image to embed the drawing as a PNG; free_places are filled blue and selected_places red, matching the colours ticket.rzd.ru uses.
get_car_imagesList the interior photographs the carriage has: titles and identifiers only. The paths it returns do not resolve to an image, so it cannot illustrate an answer - use get_car_scheme with include_image for a picture of the carriage.
get_route_stationsGet all stations for a train and direction.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
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
9/9 tools missing one or more hints — search_tickets (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_full_compartments (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); find_stations (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 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 inputs are validated
6/9 tool handlers declare input schemas (67%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Shell command execution
3 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.17.0 (high), @modelcontextprotocol/sdk@1.17.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
