Returns the list of JSON document databases.
AI agents call list_json_doc_databases to retrieve information from MCP JSON Document Collection 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 existing database metadata without creating, modifying, deleting, executing code, or committing financial actions. It is a straightforward read operation that retrieves information about available databases. Low severity because the blast radius of misuse (information disclosure about database names) is minimal and does not affect data integrity or system security.
From the tool's definition Tool name 'list_json_doc_databases' and description 'Returns the list of JSON document databases' indicate a retrieval operation with no side effects or modifications.
