List all available databases across all MySQL connections. Returns information about each database including: - Database alias (use this in mysql_query and switch_database) - Actual database name - Connection name - Active status (currently in use) - Current status (the default/selected database)...
AI agents call list_databases to retrieve information from Mysql Mcp Webui without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries database metadata across MySQL connections with no side effects. It returns informational data about available databases and their properties but does not create, modify, delete, or execute any operations on the data itself.
From the tool's definition Tool description states it 'List all available databases' and 'Returns information about each database' without any modification capabilities.
Attacks that exploit this kind of access
List all available databases across all MySQL connections. Returns information about each database including: - Database alias (use this in mysql_query and switch_database) - Actual database name - Connection name - Active status (currently in use) - Current status (the default/selected database) - Configured permissions for each operation - Optionally: table count and database size (if include_metadata is true) Databases are grouped by connection for better readability. Use the alias (not the database name) when calling other tools. It is categorised as a Read tool in the Mysql Mcp Webui MCP Server, which means it retrieves data without modifying state.
Register the Mysql Mcp Webui 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 Mysql Mcp Webui. 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 Mysql Mcp Webui MCP server (yashagldit/mysql-mcp-webui). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
