TypeScript package for Model Context Protocol (MCP) utilities and tools
mcpresso provides 20 tools across CRUD and task management domains with explicit schema definitions and descriptions. However, significant gaps exist: parameter descriptions are often minimal or missing (e.g., 'name' in create_user lacks detail on format/length), enum constraints are used but output schemas are not documented, and error handling guidance is absent. Naming follows verb_noun conventions well (get_, create_, update_, delete_, list_, search_). The framework uses Zod for validation but does not expose recovery guidance in error messages. Most tools are READ_ONLY or WRITE, with 3 DESTRUCTIVE operations lacking confirmation patterns. Overall, the server demonstrates solid foundational structure but lacks the LLM-optimized descriptions and error recovery patterns expected of A-grade tools.
Update the status of multiple tasks at once
Create a new note
Create a new task
Create a new user
Delete a note
Delete a task
Delete a user
Find all tasks that are past their due date
Get statistics about all tasks
Three destructive operations (delete_user, delete_task, delete_note) lack confirmation or dry-run patterns. No error recovery guidance provided.
Parameter descriptions are minimal or missing actionable detail. E.g., 'name' in create_user says 'Name is required' but does not specify format, length constraints, or character restrictions. LLMs cannot infer constraints from names alone.
Output schemas are not documented in visible source. Tools return results but there is no explicit specification of response field types, structure, or included IDs needed for downstream tool chaining.

No error handling or recovery guidance in tool descriptions. Destructive operations and mutation tools do not describe what to do if validation fails, resource not found, or permission denied.
Some tool names deviate from verb_noun convention (searchByStatus, searchByAssignee, getOverdueTasks). Inconsistent naming makes LLM tool selection harder when many tools are available.
List and search tools do not document pagination. No mention of page limits, result counts, or whether responses are paginated. Large result sets could exceed context window.
