Both tools have severely deficient definitions. tools/list and tools/call lack parameter descriptions entirely. tools/call has a minimal input schema with no descriptions for 'name' or 'arguments' properties. Neither tool description explains what WPS tools are, when to use each tool, or what the output structure contains. No output schemas are documented. The generic descriptions ('List all available WPS tools' and 'Execute a WPS tool') provide minimal LLM guidance for tool selection or usage. No error handling guidance is present.

• Add a detailed output schema for tools/list documenting the structure of returned WPS tools (e.g., array of {name, description, parameters})
• Expand tools/call description to explain: what WPS tools are, when to use this tool, what happens on success/failure, and example tool names
• Define the 'arguments' parameter schema with explicit properties and descriptions for common WPS tool arguments, or document the dynamic structure
• Add per-parameter descriptions: 'name' should explain it is the WPS tool identifier; 'arguments' should describe the expected object structure
• Document error cases and recovery: 'Tool not found' → suggest calling tools/list first; 'Invalid arguments' → include the constraint violated
