This server contains only a single trivial tool with severe quality gaps. The 'hello_world' tool has a minimal description (28 chars, below the 50-200 char baseline for LLM-optimized descriptions), empty input schema (no parameters defined), and no output schema documentation. The tool performs no meaningful work and does not follow any of the 54 Agentic Tool Patterns. No error handling, no parameter validation, no security considerations, and no composition with other tools. This is a skeleton/template implementation, not a production-ready MCP server.

• Rename 'hello_world' to an action verb (e.g., 'get_gcp_documentation', 'search_gcp_docs', 'list_gcp_services') that reflects actual functionality.
• Expand description to 50-200 characters explaining: what the tool does, when to use it (e.g., 'Call this to retrieve GCP documentation for a service'), and what it returns (e.g., 'Returns documentation text and links').
• Define input schema with typed parameters. If the tool searches docs, add parameters like 'query' (string, required), 'service' (enum of GCP services), 'limit' (integer, 1-100, default 20).
• Document output schema explicitly: declare that the tool returns an object with fields like 'results' (array of {title, url, snippet}), 'total_count' (integer), 'next_cursor' (string or null).
• Add error handling: catch exceptions, validate inputs, and return structured errors like '{"error": "Invalid service: got \'compute\'. Must be one of: compute, storage, bigquery, ..."}'.
