An MCP server that provides tools and resources for interacting with Pokémon data via the PokéAPI, including executing attacks and retrieving Pokémon abilities.
This server has ONE tool (attack) with a minimal, non-idiomatic definition. The tool name lacks a verb prefix and the description is vague. Parameters are typed but lack individual descriptions. No output schema is documented. The tool performs a read-only operation but lacks any defensive validation or error handling guidance. Resources are present but underutilized; the single tool is underpowered for the domain.
You can use this to execute a pokemon attack. Your moveName and pokemonName should be input as lowercase.
Tool name 'attack' lacks action verb prefix. Should be 'execute_attack' or 'perform_attack' to signal intent and match Arcade pattern conventions (get_, create_, search_, etc.).
Tool description is vague: 'You can use this to execute a pokemon attack. Your moveName and pokemonName should be input as lowercase.' It does not explain WHEN to use this tool, WHAT it returns, or how it interacts with other resources (pokemon abilities, etc.). Lacks clarity on whether the attack succeeds deterministically or is probabilistic.
Input parameters 'moveName' and 'pokemonName' have NO individual descriptions. LLMs cannot infer what format, case, or valid values these expect. Descriptions must explain: 'moveName: lowercase move identifier from PokeAPI (e.g., thunder, hydro-pump)' and 'pokemonName: lowercase pokemon identifier (e.g., pikachu, moltres)'.

No output schema documented. The tool returns {content: [{type: 'text', text: string}]} but LLMs have no way to know what structure to expect or how to extract attack success/failure or damage. A documented output schema is essential for chaining tools and downstream planning.
No error handling or recovery guidance. When PokeAPI responds with 404 (invalid move), the tool likely returns a cryptic error. Should return: 'Move not found. Call list_moves() to see valid moves.' or similar recovery hint.
Only one tool (attack) is exposed. Two resources (pokemon and pokemon-abilities) exist but are not surfaced as tools. LLMs cannot naturally discover available moves, pokemon stats, or abilities without intermediate steps. Missing tools: 'list_moves()', 'get_pokemon(pokemon_name)', 'get_pokemon_abilities(pokemon_name)'.
No idempotency guarantees or confirmation pattern. Agents calling 'attack' in a loop will execute multiple attacks without confirmation. For a gaming context, this might be acceptable, but no guards prevent runaway loops or clarify that repeated calls with identical inputs produce different results (probabilistic hit chance).
Input validation occurs silently inside PokeAPI fetch. If 'moveName' is invalid (e.g., 'THUNDER' instead of 'thunder'), the API 404 will be caught but no actionable error message guides the LLM to retry with lowercase. Implement explicit validation: if moveName !== moveName.toLowerCase(), reject with 'Move names must be lowercase (e.g., thunder, hydro-pump)'.
