This server has significant definition quality gaps. Tool descriptions are present but generic (most are 20-50 chars, below the 194-char baseline). Parameter descriptions are minimal or absent. Most critically, 6 of 8 tools have NO input schema visible in the code, they accept empty objects or are inferred. The make_query tool has a schema, but others like get_product_names, get_activities, get_product_type_options lack explicit schema definitions. Tool naming is reasonable (verb_noun pattern), but composition issues exist: get_product_type_options, get_product_subtype_options, and get_gender_options all have identical descriptions ('Get product type options'), indicating copy-paste and poor differentiation. Error handling is minimal, tools raise ValueError but provide no recovery guidance. No output schemas are documented.

• Add explicit input schemas to all 6 tools with empty inputs. Use FastMCP's schema decorators or Pydantic models to define empty-input tools formally.
• Rewrite descriptions for the three options-getter tools to be distinct and actionable: 'Get available product types (shoes, apparel, accessories)' vs 'Get available product subtypes (tops, shorts, etc.)' vs 'Get available gender filters (womens, mens, kids)'.
• Expand all tool descriptions to 100-200 chars, including WHEN to call (e.g., 'Call after make_query to retrieve product names from the filtered results') and WHAT is returned (e.g., 'Returns list of product name strings').
• Document output schemas in tool descriptions or via return type hints. E.g., 'Returns: dict[str, list[str]] mapping product name to activities list' for get_activities.
• Replace stateful SESSION_STATE with stateless design: pass query results as parameters or use resources/prompts to expose prior results, or redesign so each tool is independent.
