Get query logs (gzipped) for a Data Lake as base64-encoded gzip data
AI agents call datalake_get_logs_stream to retrieve information from MongoDB Atlas MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical query logs from a Data Lake without modifying, deleting, or executing any operations. The read-only nature of log retrieval, combined with the informational purpose of query logs, makes this a low-severity Read operation.
From the tool's definition Tool description explicitly states 'Get query logs' - a retrieval operation with no modification or deletion capability. Returns data in read-only format (base64-encoded gzip).
Attacks that exploit this kind of access
Get query logs (gzipped) for a Data Lake as base64-encoded gzip data. It is categorised as a Read tool in the MongoDB Atlas MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MongoDB Atlas MCP Server MCP server in PolicyLayer and add a rule for datalake_get_logs_stream: 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 MongoDB Atlas MCP Server. Nothing to install.
datalake_get_logs_stream 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 datalake_get_logs_stream 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 datalake_get_logs_stream. 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.
datalake_get_logs_stream is provided by the MongoDB Atlas MCP Server MCP server (montumodi/mongodb-atlas-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
