AI agents call list_databases to retrieve information from MariaDB Reader MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves metadata about available databases with no side effects. It enables exploration and discovery but does not modify, execute, or destroy any data. This is a fundamental read operation appropriate for database introspection by an AI assistant.
From the tool's definition Tool name 'list_databases' and description indicate it 'shows a list of all accessible databases' (translated from Korean: '접근 가능한 모든 데이터베이스 목록을 보여줍니다'). This is a read-only query operation with no data modification, deletion, or code execution.

접근 가능한 모든 데이터베이스 목록을 보여줍니다. It is categorised as a Read tool in the MariaDB Reader MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MariaDB Reader MCP Server MCP server in PolicyLayer and add a rule for 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 MariaDB Reader MCP Server. Nothing to install.
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 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 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.
list_databases is provided by the MariaDB Reader MCP Server MCP server (moosin76/mcp_server_mariadb_reader). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
