MCP 도구 정의를 JSON 형식으로 제공합니다.
AI agents call get_tool_definitions to retrieve information from Guardian News MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that returns static tool metadata as JSON. It does not create, modify, delete, execute code, or initiate external operations. The blast radius if misused is minimal - an agent could learn about available tool APIs, but cannot directly perform actions beyond information retrieval.
From the tool's definition Tool description states it 'provides MCP tool definitions in JSON format' - a retrieval/query operation with no side effects. The tool name 'get_tool_definitions' confirms it fetches metadata about available tools.
