The Document MCP Server defines 31 tools with varying quality. All tools have explicit names starting with action verbs (list_, create_, delete_, read_, write_, etc.), which follows naming conventions well. However, there are significant gaps in schema completeness and parameter descriptions. Of the 31 tools sampled, most have adequate descriptions (100-300 chars), but input schemas are inconsistently documented. Tools like list_chapters, create_chapter, and read_chapter have explicit schemas with typed parameters and descriptions visible in tool_descriptions.py and content_tools.py. However, many tools (particularly in context_tools.py, version_tools.py, metadata_tools.py) are referenced but their full input schemas are not shown in the provided source code excerpt. This creates uncertainty about whether all parameters are properly typed and described. Output schemas are NOT documented for any tool, no return type specifications, pagination structures, or field descriptions are visible. Error handling is minimal: no recovery guidance, no error categorization, no actionable error messages. Composition is reasonable: tools are single-responsibility (e.g., create_chapter, delete_chapter, read_chapter are separate), and tool outputs should chain (e.g., list_chapters returns chapter names that feed into read_chapter). However, there is no evidence of pagination controls (limit, offset, cursor) on list tools, which is critical for large document collections. Security concerns: no documentation of access control, audit trails, or permission gates. The server uses STDIO transport, which limits protocol readiness significantly.

• Add output schemas for all 31 tools. Document return types, field names, field types, and include-chaining IDs. Example: list_chapters should return {chapters: [{name: string, chapter_count: integer, modified_at: ISO8601}], total: integer, next_cursor?: string}.
• Add pagination parameters to all list_* tools: limit (1-100, default 20), offset (0+, default 0), and either next_cursor or total. Document in description: 'Returns max 20 items. Use offset/limit to page through results. Call list_documents(include_chapters=false) first for fast overview.'
• Enhance destructive operation descriptions with explicit recovery guidance. Example for delete_chapter: 'DESTRUCTIVE. Permanently removes chapter file. Use create_snapshot() before deleting for recovery. No undo available after execution.'
• Add error guidance to descriptions. Example for create_chapter: 'Returns error if document_name does not exist, use list_documents() first. Returns error if chapter_name already exists, provide unique filename.'
• Document scope semantics for context/memory tools. Add to store_memory description: 'conversation scope: lost after user disconnects. session scope: preserved until server restart. persistent scope: saved to disk indefinitely.'
• Clarify paragraph indexing in read_chapter description. Example: 'Returns chapters as array of paragraphs. Indices are 0-based. Use read_paragraph(paragraph_index=0) to read first paragraph.'
• Add permission/scope documentation. Example for delete_document: 'Requires write:documents permission. Operation is logged for audit trail.'

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
