Loading ToolBench
A complete project combining MCP, A2A, and Agentic RAG with centralized model management. Provides document processing, web search, and intelligent question answering through coordinated agents.
Server has 8 tools with basic schemas and descriptions, but significant gaps in parameter documentation, output schema clarity, and error handling guidance. Terminal tools (execute_command, list_files, read_file) have reasonable input schemas but lack output schema documentation. RAG tools (ingest_pdf_document, search_documents, get_rag_system_status, get_model_configuration) have minimal parameter descriptions and no documented return structures. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) present. Error messages are generic ('Error: {str(e)}') rather than actionable recovery guidance. Descriptions average ~80 chars, below the 194-char baseline for A+ tools.
Execute a terminal command securely. Restricted to safe commands only.

Query the ingested documents using agentic RAG with Gemini
RAG tools lack output schema documentation. search_documents, ingest_pdf_document, get_rag_system_status, and get_model_configuration have no documented return types or field structures. LLMs cannot plan downstream tool calls or extract required data without knowing what fields to expect.
Error handling is generic and non-actionable. All tools return 'Error: {str(e)}' without recovery guidance. Per pattern:recovery-guide, errors must tell the LLM what to do next (e.g., 'PDF not found. Verify the file path exists and is readable.').
Missing tool annotations. No readOnlyHint, destructiveHint, or idempotentHint annotations present. execute_command and ingest_pdf_document are destructive but unmarked. This prevents agents from reasoning about side effects and retry safety.

Search the web for current information and facts using SerpAPI
Parameter descriptions are minimal or absent. get_rag_system_status and get_model_configuration have empty input schemas with no parameter guidance. Even simple tools should document what each parameter controls and its valid range/format.
No pagination or result limits documented. web_search accepts max_results (1-20) but other tools lack limits. search_documents could return thousands of results, blowing context window. Per pattern:paginated-result, tools returning lists must support pagination and document limits.
