Search and list Ghost blog posts
AI agents call search_posts to retrieve information from Ghost MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing blog posts and returns results. It has no side effects—it does not create, modify, delete, or execute operations. It is a pure read operation with minimal security impact if misused by an AI agent, as the worst outcome would be unauthorized information disclosure of blog post metadata already stored in Ghost.
From the tool's definition Tool name 'search_posts' and description 'Search and list Ghost blog posts' indicate data retrieval without modification. The verbs 'search' and 'list' are characteristic Read operations.
