Search for posts across the Paragraph platform
AI agents call search-posts to retrieve information from Paragraph MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The search-posts tool retrieves data by querying posts on the platform. It performs a read-only operation—searching and returning results without creating, modifying, deleting, or executing actions. This matches the Read category definition of retrieving or querying data with no side effects.
From the tool's definition Tool name 'search-posts' and description 'Search for posts across the Paragraph platform' indicate a query operation with no side effects.
