Argo Search MCP demonstrates strong definition quality overall with well-structured schemas, comprehensive parameter documentation, and clear descriptions. All 10 tools have explicit input schemas with types and descriptions. Tool names follow verb_noun conventions (argo_search, argo_local_read, argo_fetch, etc.). Descriptions are detailed and contextual (average ~150-200 chars), explaining both purpose and use cases. Parameters are mostly well-constrained with enums, min/max bounds, and defaults. However, output schemas are not documented in the visible source code, and error handling guidance is not evident in tool definitions. Most tools are read-only (appropriate) with one WRITE tool (argo_recompute) clearly marked. The Chinese language descriptions are comprehensive but assume LLM compatibility with non-English prose.

• Document output schemas for all 10 tools in the MCP tool definitions. At minimum, specify: result structure (e.g., {results: [{title, url, snippet, source, score}]}, pagination fields (total_count, next_cursor), and error response format. Example: argo_search should document that results include fields like 'title', 'url', 'snippet', 'source', 'score' with their types.
• Add error handling guidance to each tool description. Use the pattern: 'On error: [error_condition] → [recovery_action]. E.g., 'If rate-limited (HTTP 429), retry after 60 seconds with fewer results (max_results=5).'
• Expand argo_clarify description from 73 chars to ~150 chars. Clarify distinction from argo_search: 'Use argo_clarify when the query contains ambiguous terms (company/fruit, language/animal) or unclear intent. Returns disambiguation options and recommended search strategies. After clarification, use argo_search with the disambiguated query.'
• Add schema validation examples for JSON string parameters (argo_research.work_packages). Include a minimal valid example: 'Example: [{"id":"1","question":"What is X?","query":"search term","depends_on":[]}]'
• Enhance argo_recompute security guidance. Update description: 'SECURITY WARNING: Script execution is sandboxed (read-only inputs, no network, timeout-protected, memory-limited). Always review scripts before setting allow_exec=true. Malicious code can still execute within limits; verify source before authorizing.'
• Document whitelist configuration for argo_local_read and argo_local_search. Add to descriptions: 'Requires environment variable ARGO_LOCAL_READ_DIRS (or ARGO_LOCAL_SEARCH_DIRS) with comma-separated absolute paths. If not set, all local file access is denied. Configure before deployment.'
