AI agents call get_databases to retrieve information from MySQL 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 without executing queries, modifying data, or triggering side effects. It is equivalent to 'SHOW DATABASES' in MySQL, which is a non-destructive informational query. Confidence is high because the intent is unambiguous from the name and the function of listing databases is inherently a read operation.
From the tool's definition Tool name 'get_databases' and description 'retrieves a list of available databases' indicate a query/list operation with no modification or deletion. This is a pure read operation.

Register the MySQL MCP Server MCP server in PolicyLayer and add a rule for get_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 Server. Nothing to install.
get_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 get_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 get_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.
get_databases is provided by the MySQL MCP Server MCP server (yuki777/mysql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
