get_bs
AI agents call get_bs to retrieve information from Bokicast MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool follows the naming pattern of sibling 'get_*' tools that retrieve (not modify) accounting data. Balance sheets are read-only financial statements. The empty description lowers confidence slightly, but the pattern and context strongly indicate a read operation with no side effects or data modification capability. Severity is low because retrieving accounting data poses minimal risk even if misused.
From the tool's definition Tool name 'get_bs' strongly suggests retrieving balance sheet data (standard accounting terminology). Sibling tools 'get_pl', 'get_t_account' are clearly read operations that retrieve accounting visualizations.
Attacks that exploit this kind of access
get_bs. It is categorised as a Read tool in the Bokicast MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Bokicast MCP Server MCP server in PolicyLayer and add a rule for get_bs: 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 Bokicast MCP Server. Nothing to install.
get_bs 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_bs 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_bs. 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_bs is provided by the Bokicast MCP Server MCP server (lambda-tuber/bokicast-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
