List the authenticated user's databases, optionally filtered to one project.
AI agents call list_user_databases to retrieve information from PlugLayer MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about existing databases owned by the authenticated user, filtered optionally by project. It performs a read-only operation without creating, modifying, deleting, or executing any infrastructure changes. The low severity reflects that exposure of this tool allows only data retrieval, not data manipulation or resource creation/destruction.
From the tool's definition Tool name 'list_user_databases' and description 'List the authenticated user's databases' indicate a retrieval operation with no modifications or side effects.
Attacks that exploit this kind of access
List the authenticated user's databases, optionally filtered to one project. It is categorised as a Read tool in the PlugLayer MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PlugLayer MCP Server MCP server in PolicyLayer and add a rule for list_user_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 PlugLayer MCP Server. Nothing to install.
list_user_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_user_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_user_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_user_databases is provided by the PlugLayer MCP Server MCP server (pluglayer/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
