This server exposes 23 tools via HTTP with basic Express routing. All tools have names starting with action verbs (getUser, createCourse, deleteCourse, etc.), which is good. However, the implementation suffers from CRITICAL gaps: (1) NO input schemas are visible in the source code, the tool definitions are inferred from route handlers, not explicitly registered with JSON Schema. (2) Descriptions are present but MINIMAL, most are 10 - 40 characters ('Obtener un usuario mediante correo electronico' = 42 chars), which barely meet the 10-char minimum and lack context for when/why an LLM should use the tool. (3) NO output schemas are documented anywhere. (4) NO error handling guidance, controllers return HTTP status codes and generic JSON, but no actionable recovery hints. (5) Several tools combine related concerns (e.g., forgotPassword + recoveryPassword could be a single flow; editPassword and editEmail are separate when they could be composed). (6) Tool definitions are NOT REGISTERED explicitly in an MCP tools capability, they appear to be plain Express routes, so the actual schema, input validation, and return types are inferred from inspection, not declared. Per the hard rules, inferred tools cap at 50, and tools without visible schemas cap their schema score at 0. Because this is an HTTP server that IS remotely callable (not STDIO), protocolReadiness is scored normally, but the lack of explicit MCP tool registration and schema visibility heavily penalizes definitionQuality.

• Explicitly register all 23 tools in an MCP tools capability with full JSON Schema input definitions. Example for getUser: {'type': 'object', 'properties': {'email': {'type': 'string', 'description': 'User email address (required)'}}, 'required': ['email']}.
• Expand all descriptions to 50 - 150 characters with context. Example: 'getUser: Retrieve a user by email. Returns id, username, role, and verified status. Use this to look up a specific user before editing their role or permissions.' Instead of 'Obtener un usuario mediante correo electronico'.
• Document output schemas for every tool. Example for getCourses: 'Returns {courses: [{id: number, title: string, level: string, image_url: string}], total_count: number, has_more: boolean}'.
• Add actionable error messages with recovery hints. E.g., if getUser fails with 'User not found', respond: 'User not found (404). No account exists for this email. Call register() to create one, or check the spelling.'
• Add per-parameter descriptions for all enum/constrained inputs. E.g., role: 'User access tier. ADMIN = full system access; PREMIUM = course access; FREE = limited course access.'
• Implement confirmation or dry-run for deleteCourse and deleteClass. E.g., add a 'confirm' boolean param (default false): 'If true, permanently delete the course. If false, return what would be deleted without making changes.'
• Consolidate password recovery into a single multi-step workflow: getForgotPasswordCode(email) → verifyAndResetPassword(email, code, newPassword). Document the sequence in descriptions.
