List all collections in a MongoDB database
AI agents call mongo-list-collections 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 read-only operation to enumerate collections. It has no side effects, creates no data, executes no arbitrary code, and cannot delete or modify anything. The blast radius of misuse is minimal—an agent could only discover what collections exist in the database. This is a straightforward Read category classification.
From the tool's definition Tool name 'mongo-list-collections' and description 'List all collections in a MongoDB database' indicate a query operation that retrieves database metadata without modifying data.
Attacks that exploit this kind of access
List all collections in a MongoDB database. 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-list-collections: 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-list-collections 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-list-collections 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-list-collections. 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-list-collections 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.
