List accessible Umami websites. Returns id, name, domain, and createdAt for each website.
AI agents call umami_list_websites to retrieve information from Umami MCP Server 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 analytics website metadata without creating, modifying, deleting, or executing any operations. It is a straightforward read operation consistent with the read-only nature of the Umami MCP server. The blast radius of misuse is minimal—listing websites only exposes non-sensitive identifiers and configuration data that would typically be visible to authenticated analytics users.
From the tool's definition Tool description states 'List accessible Umami websites' and returns metadata (id, name, domain, createdAt). Server is explicitly described as 'Read-only MCP server' that 'talks to the Umami REST API directly over HTTP' with no side effects mentioned.
