This OneDrive CLI MCP server has significant definition quality gaps that limit agent reasoning and safety. While tool names follow verb-noun conventions (df, ls, cat, cp, mkdir, mv, rm, share, version, auth), descriptions are present but lack LLM-optimized detail. Critical issues: (1) Most input schemas lack parameter descriptions entirely, 'remote' and 'src'/'dst' parameters have minimal guidance on expected format or constraints. (2) Output schemas are not documented, agents cannot predict what fields to expect, forcing blind calls. (3) Risk annotations (READ_ONLY, WRITE, DESTRUCTIVE) are metadata but not integrated into tool annotations per current MCP spec. (4) The 'auth' tool has an empty input schema but performs a WRITE operation with OAuth side effects, no confirmation pattern or dry-run option. (5) 'rm' is destructive (rm -rf equivalent) but has no confirmation gate. (6) Parameter naming inconsistency: 'remote' vs 'src'/'dst' vs 'path' makes chaining ambiguous. (7) No pagination support documented for 'ls', which could return thousands of files. (8) 'share' accepts freeform 'type' and 'scope' strings instead of enums, inviting hallucination.

• Add explicit enum constraints to share tool: type must be one of [view, edit, embed], scope must be one of [anonymous, organization, users]. Document each value's semantics.
• Document output schemas for all tools. Example for ls: returns array of {name, size_bytes, modified_time_iso8601, is_folder, web_url}. Example for df: returns {total_bytes, used_bytes, available_bytes, quota_percent, deleted_items_count}.
• Implement confirmation pattern for destructive operations (rm, mv with overwrite). Add dry_run parameter or require explicit force_delete=true to prevent accidental deletes.
• Standardize parameter naming: use 'onedrive_path' for all OneDrive file paths (instead of 'remote', 'path', 'src', 'dst'). Add validation: must be absolute path (start with /) or relative (no leading /).
• Add parameter descriptions with format constraints. Example: 'remote: Absolute path in OneDrive (e.g., /Documents/file.txt). Paths are case-insensitive and must be URL-encoded if they contain spaces or special characters.'
• Add pagination to ls: introduce limit (1 - 1000, default 50) and offset (default 0) parameters. Document: 'Results capped at 1000 items max. Use offset/limit for iteration.'
• Add recovery guidance to tool descriptions. Example for auth: 'Authenticates with OneDrive using OAuth 2.0. Obtains a bearer token stored in ~/.onedrive-cli-token. Required before any other operations. If auth fails, verify network connectivity and that your Azure App ID is registered.'
• Convert Risk metadata to MCP tool annotations: add readOnlyHint: false to cp, mkdir, mv, rm, share, auth; add destructiveHint: true to rm; add idempotentHint: true to ls, df, cat, version.
