A structured framework bringing uniformity to agent orchestration
This MCP server exposes 3 tools (calculate, get_country_info, convert_units) with minimal quality. Tool descriptions are present but extremely generic and lack actionable context for LLM decision-making. Input schemas are visible and structurally sound with proper types, but parameter descriptions are trivial one-liners that violate the 10-1024 character guideline (most are under 50 chars and provide no context about constraints, formats, or when to use each tool). No output schemas are documented. Error handling is absent, no guidance on what failures look like or how to recover. The tools themselves are simplistic utility functions that don't reflect real-world agent patterns. No tool demonstrates the composition, chaining, or complexity expected in production MCP servers.
Evaluate a mathematical expression safely
Convert between common units
Get basic information about a country
Parameter descriptions are trivial single-liners (6-30 chars) that fail to guide LLM behavior. Example: 'Mathematical expression to evaluate' provides no constraints on format, supported operators, or error cases.
No output schemas documented for any tool. Callers do not know what fields to expect, preventing downstream tool composition and forcing LLMs to guess at response structure.
Tool descriptions are generic and do not explain WHEN to use each tool or what distinguishes it from alternatives. 'Get basic information about a country' is vague, does it return population, capital, currency, area, all of the above?

No error handling or recovery guidance. If 'calculate' receives an invalid expression, what error does it return? Can the LLM retry? Should it reformulate the expression?
No constraints on numeric ranges or unit enums. 'convert_units' accepts 'from_unit' and 'to_unit' as free-form strings, no enum, no validation. LLMs will hallucinate unit names like 'meteres' or 'kilogrames'.
Tool names lack action verbs that clearly distinguish intent. 'get_country_info' is passive; better names like 'lookup_country_details' or 'search_country_stats' would be more actionable. Naming inconsistency: 'get_*' vs 'convert_*' uses different patterns.
