AI agents call list_clones 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 performs a read-only query operation on the NDB system to list clones with optional filtering by various attributes (id, name, description, etc.). It has no side effects and does not create, modify, delete, or execute operations.
From the tool's definition Tool description states 'Get all database clones' with filtering capabilities. The tool retrieves and queries clone objects without modifying, deleting, or executing any operations.

Get all database clones. Filtering is done using valueType and value fields, which are used to filter the response sent by the NDB API, for flexible filtering. You can filter by any of the following attribute names available in the clone object: - id: clone id, string - name: name of the clone, string - description: description of the clone, string - ownerId: Id of the user who created the clone, string - dateCreated: date when the clone was created - dateModified: date when the clone was last modified - databaseName: name of the source database, string - type: type of the database engine (postgres_engine, oracle_engine, etc.) - status: current status of the clone (e.g. 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_clones: 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_clones 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_clones 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_clones. 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_clones 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.
