This MCP server provides 5 tools for Indonesian stock market news retrieval and pipeline management. While all tools have descriptions and most have input schemas, the quality is inconsistent. Tool naming follows verb_noun convention (get_, read_, check_, run_) which is good. However, parameter descriptions are generic and lack specificity about constraints, formats, and expected values. Some tools have minimal or absent schema details for empty-object parameters. Error handling guidance is not visible in the code, and output schemas are completely undocumented. The server operates over STDIO only, which is a hard transport limitation. Most critically, there is no visible error recovery guidance, output schema documentation, or per-parameter validation rules, all critical for production agent tooling.

• Document complete output schemas for all tools in the tool definition. Include field names, types, required status, and examples. Example: get_news should return {articles: [{title: string, source: string, date: string, url: string, snippet: string}], total_count: number, timestamp: string}
• Add minimum/maximum bounds for numeric parameters. E.g., max_items: min 1, max 1000; days_back: min 1, max 365; top_k: min 1, max 100; max_chars: min 100, max 10000.
• Correct type declarations: use 'integer' instead of 'number' for count and day parameters in get_news to prevent float values.
• Add detailed descriptions for tools with empty parameter schemas. For read_condensed_news, explain: 'Reads the file news_condensed.txt from the project root. Returns the condensed news report generated by the most recent pipeline run. Use this to retrieve results without re-running the full pipeline.' For check_docker_status, explain what it returns: 'Returns a status object indicating whether Milvus, etcd, and minio containers are running, plus details on any missing containers.'
• Document idempotency and retry safety. For run_news_pipeline_async, state: 'Starts a background pipeline run. Safe to call multiple times; each invocation starts a new independent run. Check get_news_status() to monitor progress. Returns immediately; the pipeline runs asynchronously.'
• Add error recovery guidance. Example: 'If get_news fails with Docker error, call check_docker_status() to verify containers are running. If containers are down, the pipeline cannot proceed, Docker must be restarted.' Include this in tool descriptions or as contextual help.
