NeuroLink MCP server presents a documentation-focused toolkit with 6 READ_ONLY tools. Tool naming follows verb_noun convention (search_docs, get_page, list_sections, get_api_reference, get_examples, get_changelog). All tools have descriptions between 80-150 chars, meeting the 10-1024 char guideline. Input schemas are present for all tools with typed parameters. However, there are notable gaps: output schemas are not documented in the provided code, parameter descriptions lack depth and formatting constraints, and error handling patterns are not visible. The server operates on STDIO transport only, which caps protocol readiness at 50 and indicates this is a local/CLI integration rather than production agent-ready. All tools are read-only with low security risk, but the lack of output documentation and LLM-optimized descriptions limits agent reasoning quality.

• Document output schemas for each tool. Example for search_docs: 'Returns array of {title: string, description: string, section: string, path: string, score: number}. Limited to max 50 results. If results truncated, include next_cursor for pagination.'
• Convert parameter enums to JSON Schema format: add 'enum: ["features", "sdk", "cli", "mcp", "rag", "examples"]' to schema instead of hiding in description text.
• Add constraint descriptions to numeric parameters. Example: 'limit: Max number of results (1-50, default 10). Values outside range will be clamped.'
• Enhance tool descriptions with disambiguation and dependency hints. Example: 'Use search_docs to find relevant documentation by keyword. Once you have a path, call get_page for the full content. Use list_sections first to browse available docs by category.'
• Add error handling guidance to descriptions. Example for get_page: 'Returns full page content as markdown. If path does not exist, returns 404 with suggestions: "Path not found. Did you mean: getting-started/install, getting-started/quickstart?"'
• Document pagination behavior in search_docs description: 'Results are limited to 50 items. If limit is hit, include total_count in response so agent knows if more results exist.'
• Add examples to descriptions showing expected parameter values. Example: 'path examples: "getting-started/installation", "features/multimodal", "api/sdk-reference"', but place in description, not in schema where LLMs might treat as constraints.
