What get-trains does on Cowork Bench
AI agents call get-trains to retrieve information from Cowork Bench without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get-trains is rated Low
This is a search and retrieval operation that queries Russian Railways (РЖД) train data between two stations for a given date and returns information about available trains. It has no side effects, does not create, modify, or delete data, and does not execute code or trigger external operations beyond the query itself. This is a straightforward Read category tool with low severity.
From the tool's definition Tool description: 'Поиск поездов РЖД на заданную дату между двумя станциями. Возвращает список поездов...' — the verbs 'Поиск' (search) and 'Возвращает' (returns) indicate data retrieval with no modification.
Attacks that exploit this kind of access
The rule that runs get-trains safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Cowork Bench, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get-trains, this is the rule to start with:
get-trains is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Cowork Bench, apply this rule, and every get-trains call is checked against it from then on.
Questions about get-trains
Поиск поездов РЖД на заданную дату между двумя станциями. Возвращает список поездов с временем отправления/прибытия, длительностью в пути и наличием/ценой по классам (Эконом, Эконом+, Бизнес). It is categorised as a Read tool in the Cowork Bench MCP Server, which means it retrieves data without modifying state.
Register the Cowork Bench MCP server in PolicyLayer and add a rule for get-trains: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Cowork Bench. Nothing to install.
get-trains is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get-trains rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get-trains. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get-trains is provided by the Cowork Bench MCP server (0717376/cowork_bench). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
