This MCP server has significant definition quality issues. Only 4 tools are defined, and while they have basic schemas and descriptions, the descriptions are sparse (10-40 chars) and lack context for LLM selection. Tool naming is reasonable (verb-based: add, greet, process_document, get_server_status) but descriptions are minimal. The 'add' and 'greet' tools are toy examples, not production use cases. Parameter descriptions exist but are terse (e.g., 'First number', 'User name'). No output schemas are documented. Error handling is absent. The 'process_document' tool accepts an optional 'options' object with type 'object' but no description of what options are valid, this violates constrained-input pattern. Overall, this reads as a minimal example server, not production-grade.

• Expand all tool descriptions to 50-200 characters. Follow the pattern: WHAT does it do? WHEN should the LLM call it (vs similar tools)? WHAT does it return? Example: 'add' → 'Compute the sum of two integers. Use this to perform arithmetic calculations; returns the numeric result.'
• Document output schemas for all tools. Specify the return type, fields, and structure. Example for 'add': {"type": "object", "properties": {"result": {"type": "integer", "description": "The sum of a and b"}}, "required": ["result"]}
• Enhance parameter descriptions with format, range, and constraint hints. Example for 'a': 'First number to add (integer, range: -9223372036854775808 to 9223372036854775807)' instead of 'First number'.
• Replace the generic 'options' object in process_document with explicit, documented parameters or an enum of valid option keys. If options are dynamic, document the expected schema and provide examples.
• Add error handling guidance to all tools. For greet, specify: 'Returns error if name is empty or exceeds 256 characters.' For process_document, document: 'Returns 404 if document_id not found. Returns 429 if rate-limited; retry with exponential backoff.'
• Replace toy tools (add, greet) with real Terraform documentation functionality: search_terraform_docs, get_resource_schema, validate_terraform_config, list_terraform_providers. These align with the server's actual purpose.
• Implement pagination for tools that return lists. Even status tools should return a 'next_cursor' field if results are potentially large.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
