Get the total count of documents in the MongoDB Atlas knowledge base.
AI agents call get_document_count to retrieve information from Sample MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the database to return an aggregate count statistic. It performs no mutations, deletions, code execution, or financial operations. The operation is informational only and has minimal blast radius if misused by an agent - worst case would be learning the total document count.
From the tool's definition Tool retrieves count metadata from MongoDB Atlas knowledge base with description 'Get the total count of documents' - a pure read operation with no side effects
Attacks that exploit this kind of access
Get the total count of documents in the MongoDB Atlas knowledge base. It is categorised as a Read tool in the Sample MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sample MCP Server MCP server in PolicyLayer and add a rule for get_document_count: 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 Sample MCP Server. Nothing to install.
get_document_count 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_document_count 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_document_count. 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_document_count is provided by the Sample MCP Server MCP server (satinath-nit/sample-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
