What mongosh-stats does on Cargo
AI agents call mongosh-stats to retrieve information from Cargo without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why mongosh-stats is rated Low
This tool queries and returns metadata and statistics about MongoDB databases without creating, modifying, deleting, or executing arbitrary operations. It has no side effects on the database and presents minimal risk even if invoked by an AI agent, as it only exposes informational queries about database structure and size.
From the tool's definition Tool description specifies 'Gets MongoDB database statistics' - retrieving collections, objects, data size, storage, and indexes information with no modification or deletion of data.
Attacks that exploit this kind of access
The rule that runs mongosh-stats safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Cargo, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mongosh-stats, this is the rule to start with:
mongosh-stats 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 Cargo, apply this rule, and every mongosh-stats call is checked against it from then on.
