AI agents call get_bulk_data to retrieve information from Bloomberg MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a Read operation: it retrieves bulk financial data from Bloomberg without creating, modifying, or deleting any resources. However, severity is elevated to 'high' because bulk market data access could expose sensitive financial information (competitive intelligence, trading patterns, portfolio holdings) if an AI agent misuses it to exfiltrate large datasets or exploit API rate limits.
From the tool's definition Tool name 'get_bulk_data' and description 'バルクデータを取得します（BDS機能相当）' (Retrieve bulk data / equivalent to BDS function) indicates data retrieval without modification.

Register the Bloomberg MCP Server MCP server in PolicyLayer and add a rule for get_bulk_data: 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 Bloomberg MCP Server. Nothing to install.
get_bulk_data 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_bulk_data 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_bulk_data. 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_bulk_data is provided by the Bloomberg MCP Server MCP server (shunsuketamura06/simple-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
