Get statistics for the MongoDB database
AI agents call mongo_get_database_stats to retrieve information from Mcp Database without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistical metadata about a MongoDB database (e.g., storage size, document counts, index information). It performs no side effects, creates no data, executes no arbitrary code, and makes no modifications. It is a pure informational query operation consistent with the 'Read' category. Low severity reflects minimal blast radius if misused by an agent.
From the tool's definition Tool name 'mongo_get_database_stats' and description 'Get statistics for the MongoDB database' indicate a read-only query operation that retrieves database statistics without modifying data.

Get statistics for the MongoDB database. It is categorised as a Read tool in the Mcp Database MCP Server, which means it retrieves data without modifying state.
Register the Mcp Database MCP server in PolicyLayer and add a rule for mongo_get_database_stats: 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 Mcp Database. Nothing to install.
mongo_get_database_stats 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 mongo_get_database_stats 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 mongo_get_database_stats. 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.
mongo_get_database_stats is provided by the Mcp Database MCP server (nam088/mcp-database-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
