Loading ToolBench
A Model Context Protocol (MCP) server for Anime.js animation library, providing AI assistants with access to Anime.js components, APIs, examples, and documentation.
Five tools with basic verb-noun naming (get_, list_, search_) and descriptions present. However, critical gaps undermine quality: (1) Input schemas visible in code but lack type definitions for most parameters, only 'componentName', 'category', 'exampleType', 'query', 'topic' are declared as strings with descriptions, but no enums, ranges, or validation constraints. (2) Descriptions are generic and under-optimized for LLM selection, e.g., 'Get information and examples for a specific Anime.js component or API' (79 chars) lacks WHEN to use it or what distinguishes it from get_anime_example. (3) Output schemas are completely undocumented, no indication of what fields are returned, structure, or pagination. (4) No error handling guidance visible, tools do not indicate what happens on invalid input, missing resources, or API failures. (5) Parameters lack depth: 'category' in list_anime_components has no enum constraint (valid values: core, timeline, utilities, svg are mentioned in description but not enforced). Baseline: 194 chars avg description, 72 chars avg param annotation, these tools average ~60 chars descriptions and minimal param detail.
Get information and examples for a specific Anime.js component or API
Get documentation for Anime.js features and concepts
Get example code for a specific Anime.js animation pattern
Get all available Anime.js components and APIs
Search Anime.js examples and code snippets
Output schemas completely undocumented. No indication of return types, field structure, or pagination. LLMs cannot plan downstream calls or extract required data.
Parameter constraints not enforced via schema. 'category' in list_anime_components mentions valid values (core, timeline, utilities, svg) in description but lacks enum constraint. Free-form strings invite hallucinated values.
Descriptions are generic and under-optimized for LLM selection. Average ~60 chars vs. baseline 194 chars. Lack WHEN to use, dependencies, or distinction from similar tools. E.g., get_anime_component vs. get_anime_example distinction unclear.

No error handling guidance. Tools do not indicate what happens on invalid input (e.g., unknown componentName), missing resources, or API failures. LLMs have no recovery path.
No pagination or result limits documented. search_anime_examples and list_anime_components may return unbounded results, risking context window exhaustion.
