Loading ToolBench
This server has critical gaps in tool definition quality. Only 3 of 5 tools relate to the stated domain (visa checking); 2 are placeholder discovery tools (add, fetch-weather). The visa tools lack documented output schemas, making it impossible for LLMs to understand what fields are returned. Most tools have bare-minimum descriptions (10-30 chars) that don't explain WHEN to use them or WHAT they return. No parameter descriptions are provided in the source, only type declarations. The tools are readable but fall far short of production quality. The server conflates tools (visa tools vs. demo tools) and lacks the structured guidance production agents need.
Add two numbers together
Get current visa appointment availability from all centers
Get current weather information for a city
Get only visa centers with open appointments
Search visa centers with detailed filtering options
No output schemas documented for ANY tool. LLMs cannot understand what fields are returned or plan multi-step operations. This is a hard blocker for agentic composition.
Tool descriptions are generic placeholders (10 - 57 chars). Current descriptions are insufficient for LLM selection.
Parameter descriptions are missing or generic in source. The input schemas show types and enums, but lack descriptions of what each param controls. E.g., 'country_code', is this ISO 3166-1 alpha-3? Is it required? What happens if omitted?

Domain dilution: 'add' and 'fetch-weather' are unrelated to visa checking and should not be in this server. They signal lack of focus and confuse LLMs about the server's purpose.
No error handling guidance. Tools have no descriptions of what errors might occur (e.g., 'no appointments available', 'invalid country code') or how to recover. LLMs will be stuck on failure.
Lack of pagination guidance. 'fetch-visa-appointments' and 'search-visa-centers' may return large result sets, but no limit, offset, or next_cursor parameters are documented. Results could exhaust the context window.
No response field naming consistency. It's unclear whether 'country_code' in the request maps to the same field in the response, or if responses return 'origin', 'from', 'country', etc. Mismatched naming forces LLM reasoning overhead.
