DocumentMCP has 3 tools with basic definitions but significant quality gaps. Tool names follow verb_noun convention (read_doc_contents, edit_document, list_docs_meta), which is good. However, descriptions are minimal (10-50 chars), parameter descriptions are sparse or missing, and input schemas lack proper type declarations. The edit_document tool is destructive but has no confirmation mechanism or dry-run option. No output schemas are documented. Error handling is minimal, tools raise ValueError but provide no recovery guidance. The server uses FastMCP (Python), not the Go SDK listed in the repo header, creating confusion about the actual implementation.

• Add a confirm_edit_document tool or implement a dry-run parameter to edit_document. Return a preview of changes before committing. This follows pattern:confirmation-request and prevents accidental data loss.
• Expand parameter descriptions: 'old_str' should note 'Must match exactly, including whitespace and case. If not found, the document is unchanged.' 'new_str' should clarify max length and allowed characters.
• Document output schemas formally. E.g., read_doc_contents returns {type: 'string', description: 'The full text content of the document'}. list_docs_meta should return {type: 'array', items: {type: 'string'}, description: 'List of document IDs'}.
• Enhance error messages with recovery hints. Instead of 'Doc with id X not found', return 'Doc with id X not found. Available docs: deposition.md, report.pdf, financials.docx. Did you mean one of these?'
• Rename list_docs_meta to list_documents or get_document_ids to match actual behavior. Update description to 'List all available document IDs.' If metadata (count, char stats) is truly returned, implement it and update the description.
