List all configured KDB+ databases
AI agents call kdb_list_databases to retrieve information from KDB MCP Service 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 databases, retrieving metadata without side effects. It falls clearly into the Read category as it only queries and returns information about configured databases without creating, modifying, deleting, or executing any operations.
From the tool's definition Tool name 'kdb_list_databases' and description 'List all configured KDB+ databases' indicate a retrieval operation with no modification or execution of code.
Attacks that exploit this kind of access
List all configured KDB+ databases. It is categorised as a Read tool in the KDB MCP Service MCP Server, which means it retrieves data without modifying state.
Register the KDB MCP Service MCP server in PolicyLayer and add a rule for kdb_list_databases: 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 KDB MCP Service. Nothing to install.
kdb_list_databases 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 kdb_list_databases 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 kdb_list_databases. 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.
kdb_list_databases is provided by the KDB MCP Service MCP server (riteshsonawala/kdb-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
