List all available entity kinds (tables) in the Datastore
AI agents call datastore_list_kinds to retrieve information from MCP Datastore 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 simple enumeration of available kinds/tables in a Datastore—a read-only query operation. There is no capability to execute code, modify data, delete data, or perform financial operations.
From the tool's definition Tool name 'datastore_list_kinds' and description 'List all available entity kinds (tables) in the Datastore' indicate a retrieval operation with no data modification or side effects.
Attacks that exploit this kind of access
List all available entity kinds (tables) in the Datastore. It is categorised as a Read tool in the MCP Datastore Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Datastore Server MCP server in PolicyLayer and add a rule for datastore_list_kinds: 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 Datastore Server. Nothing to install.
datastore_list_kinds 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 datastore_list_kinds 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 datastore_list_kinds. 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.
datastore_list_kinds is provided by the MCP Datastore Server MCP server (johnreitano/daisy). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
