List members and backers of an OpenCollective account.
AI agents call oc_get_members to retrieve information from OpenCollective 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 publicly accessible membership data from OpenCollective. While membership lists may contain personal information, listing/querying data is a Read operation. The blast radius of misuse is limited to information disclosure of already-public or semi-public collective membership data, not financial transactions, infrastructure changes, or irreversible data loss.
From the tool's definition Tool name 'oc_get_members' and description 'List members and backers of an OpenCollective account' indicate a query/retrieval operation with no modification, deletion, or side effects.
