AI agents call list_dbservers to retrieve information from NDB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and queries data from Nutanix Database Service environments. It supports filtering and optional data loading but performs no state changes, side effects, or irreversible actions. The blast radius of misuse is minimal—an attacker could at worst enumerate database infrastructure details to inform further attacks, but cannot directly compromise systems through this tool alone.
From the tool's definition Tool name is 'list_dbservers' and description states 'Get all database servers' with optional parameters to 'include information about databases and/or clones' and filtering capabilities. No create, modify, delete, or execute operations are described.
Attacks that exploit this kind of access
Get all database servers. You can include information about databases and/or clones hosted on the db server by using the loadDatabases or loadClones parameters. Filtering is done using valueType and value fields, which are used to filter the response sent by the NDB API, for flexible filtering. Available Filters (valueType/value pairs): - name: name of the dbserver VM - description: description of the dbserver - ipAddresses: array of IP addresses (partial match supported) - fqdns: array of FQDNs (partial match supported) - status: Operational status (UP=DbServer VM is up and running, DOWN=DbServer VM is down, PROVISIONING=in progress, FAILED=error state) - nxClusterId: Nutanix cluster ID - databaseType: type of the database engine (postgres_database, oracle_database, etc.) - dbserverClusterId: ID of the logical cluster - databases: number of databases (use valueType =. It is categorised as a Read tool in the NDB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the NDB MCP Server MCP server in PolicyLayer and add a rule for list_dbservers: 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 NDB MCP Server. Nothing to install.
list_dbservers 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 list_dbservers 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 list_dbservers. 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.
list_dbservers is provided by the NDB MCP Server MCP server (rouxton/ndb-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
