WHAT IT DOES

What mongosh-stats does on Build

AI agents call mongosh-stats to retrieve information from Build without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why mongosh-stats is rated Low

This tool performs informational queries against a MongoDB database to collect statistics. It has no capability to modify, delete, or execute arbitrary operations—it only retrieves metadata and statistics about the database. The severity is low because the blast radius of misuse is minimal; an agent could only learn details about database structure and size, which is non-sensitive operational information.

From the tool's definition The tool description states it 'Gets MongoDB database statistics' (collections, objects, data size, storage, indexes), which are read-only query operations that retrieve information without modifying data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs mongosh-stats safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Build, 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 Allowed

mongosh-stats is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "mongosh-stats": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Build, apply this rule, and every mongosh-stats call is checked against it from then on.
