Retrieve users who reposted a specific post.
AI agents call getPostsRepostedBy to retrieve information from Xdevplatform/xmcp 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 information about users who reposted a post. It performs a retrieval operation without modifying, deleting, or executing any actions. The blast radius of misuse is minimal—an agent could only access metadata about reposts, which is typically public social media data. This is a straightforward Read operation.
From the tool's definition Tool name 'getPostsRepostedBy' and description 'Retrieve users who reposted a specific post' indicate a data retrieval operation with no side effects.
