Get all clusters in the project
AI agents call cluster_get_all to retrieve information from MongoDB Atlas 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 and returns existing cluster information without side effects. It is a read-only operation that retrieves data from MongoDB Atlas, matching the 'Read' category definition of queries and retrievals with no side effects. The severity is low because exposure of cluster metadata, while sensitive, does not directly enable data destruction, financial transactions, or code execution.
From the tool's definition Tool name 'cluster_get_all' and description 'Get all clusters in the project' indicate a retrieval operation with no modification, deletion, or execution of code.

Get all clusters in the project. It is categorised as a Read tool in the MongoDB Atlas MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MongoDB Atlas MCP Server MCP server in PolicyLayer and add a rule for cluster_get_all: 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 MongoDB Atlas MCP Server. Nothing to install.
cluster_get_all 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 cluster_get_all 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 cluster_get_all. 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.
cluster_get_all is provided by the MongoDB Atlas MCP Server MCP server (montumodi/mongodb-atlas-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
