ag-grid-cli is a STDIO-only CLI tool, not an MCP server. The bundled code shows 9 tools with schemas and descriptions present, but several critical gaps limit quality. Tool names lack consistent verb-noun patterns (e.g., 'detect-version' vs 'set-version' vs 'list-versions'). Descriptions are present but brief (avg ~60 chars, below the 194-char baseline). Parameter descriptions exist but lack detail on constraints, formats, and dependencies. Output schemas are not documented. Error handling is minimal, no recovery guidance or categorization. The tool set is domain-specific (AG Grid documentation) but composition is weak: tools like 'search-docs', 'articles', 'definitions', and 'examples' overlap significantly and could be unified. No tool annotations (readOnlyHint/destructiveHint). Security: 'set-version' is a write operation but lacks dry-run confirmation or permission checks.

• Standardize tool names to verb_noun format with underscores: 'detect_version', 'set_version', 'list_versions', 'search_docs', 'get_articles', 'get_definitions', 'get_examples'. Consistency enables LLM parsing.
• Document output schemas for all tools. Example for search_docs: {results: [{title: string, url: string, snippet: string}], total: number, next_cursor?: string}. This enables LLM planning and field extraction.
• Consolidate 'articles', 'definitions', 'examples' into a single 'get_documentation' tool with action enum (list|get) and type enum (article|definition|example). Reduces cognitive load and tool count.
• Add constraint details to parameter descriptions: 'limit: max 100 results per call (default 20)', 'version: semantic version string (e.g., 32.0.0)', 'language: defaults to typescript if omitted'.
• Add error recovery hints: 'If version not found, call list_versions() to see available versions.' Include categorization: 'This error is retryable, the API may be temporarily unavailable.'
