WHAT IT DOES

What list_apis does on MCP-APIKit

AI agents call list_apis to retrieve information from MCP-APIKit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why list_apis needs a policy

The tool retrieves and lists available APIs from the Eolink OpenAPI catalog. This is a read-only operation with no side effects—it queries existing data for display purposes. No data is created, modified, deleted, or executed. Confidence is slightly reduced because the description is empty, but the tool name and server context strongly indicate a read operation consistent with similar tools on the same server.

From the tool's definition Tool name 'list_apis' indicates a listing/retrieval operation. The server description emphasizes 'fetching API information' and the sibling tools ('get_api', 'get_project', 'list_projects', 'search_apis') are all read-only information retrieval operations,…
