MCP server for e-commerce product queries using ReAct pattern with LLM reasoning and SEO optimization via reflexion
This server has significant definition quality gaps. Tool descriptions are present but often generic or incomplete (e.g., 'Agente ReAct con LLM real' lacks specificity on when/why to use it). Input schemas are visible for most tools but lack depth: many parameters are typed as 'object' with minimal description (think_node, act_node, observe_node, seo_actor, seo_evaluator, seo_reflector). Parameter descriptions are sparse or missing entirely. Output schemas are not documented. Error handling is minimal, no recovery guidance or error classification. The server mixes high-level orchestration tools (llm_react_agent, improve_product_description_with_reflexion) with low-level graph nodes (think_node, act_node, observe_node), violating single-responsibility principle. No tool annotations (readOnlyHint/destructiveHint) despite clear risk levels. Spanish descriptions reduce LLM clarity.

Agente ReAct con LLM real que responde consultas de e-commerce usando patrón Reasoning + Acting
Graph node tools (think_node, act_node, observe_node, seo_actor, seo_evaluator, seo_reflector) expose internal LangGraph state objects as parameters with minimal documentation. Parameter type is 'object' with vague description 'Estado actual de HybrisReActState' or 'SEOReflexionState'. LLMs cannot infer the structure of these state objects and will fail to construct valid calls.
No output schemas documented for any tool. Callers cannot know what fields to expect, forcing LLMs to guess at response structure. This violates the documented output schema requirement and breaks tool chaining.

Tool descriptions are in Spanish, reducing clarity for English-speaking LLMs and developers. Descriptions like 'Busca productos en el catálogo usando un término' and 'Obtiene detalles específicos de un producto por ID' lack context on when/why to use each tool vs. alternatives.
No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear risk levels. llm_seo_improvement and seo_actor are marked WRITE but lack destructiveHint annotation. This prevents agents from understanding which tools are safe to retry.
Architectural violation: graph node tools (think_node, act_node, observe_node, seo_actor, seo_evaluator, seo_reflector) should not be exposed as MCP tools. These are internal LangGraph components. Expose only high-level orchestration tools (llm_react_agent, improve_product_description_with_reflexion) and let the server manage the graph internally.
