Query documents from a MongoDB collection
AI agents call mongo-find-documents to retrieve information from MCP Server Boilerplate without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query operation (find) on MongoDB, which is a standard read operation that retrieves data from a collection. It has no side effects—it does not create, modify, delete, or destroy data. The query results depend on the filter arguments provided, but the operation itself is non-destructive and reversible.
From the tool's definition Tool name 'mongo-find-documents' and description 'Query documents from a MongoDB collection' indicate a read-only operation that retrieves data without modification.

Query documents from a MongoDB collection. It is categorised as a Read tool in the MCP Server Boilerplate MCP Server, which means it retrieves data without modifying state.
Register the MCP Server Boilerplate MCP server in PolicyLayer and add a rule for mongo-find-documents: 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 Server Boilerplate. Nothing to install.
mongo-find-documents 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-find-documents 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-find-documents. 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-find-documents is provided by the MCP Server Boilerplate MCP server (ricleedo/mongo-boilerplate-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
