MCP server for generating IDs with different algorithms
Single tool 'generate-id' has a clear action verb and basic schema with enum constraints. However, the tool description is generic (23 chars: 'Generate IDs with different algorithms'), falling below the 50-200 char LLM-optimized baseline. Parameter descriptions are minimal (algorithm: 'The ID generation algorithm to use', quantity: 'Number of IDs to generate'), adequate but lack context on when to use each algorithm or constraints on quantity. No output schema is documented. Error handling returns plain text without recovery guidance. The tool is read-only and simple, but lacks the depth expected for production use.
Generate IDs with different algorithms
Tool description is too short (23 chars) and lacks context. Should explain WHEN to use each algorithm (e.g., 'cuid2 for distributed systems, uuid for standards compliance, nanoid for URL-safe IDs, ulid for sortable timestamps') and any performance/collision implications.
No output schema documented. LLMs cannot plan downstream operations or validate results. Should document: returns array of strings (IDs), or single string if quantity=1, with format hints (e.g., 'cuid2: 24-char alphanumeric, uuid: 36-char with hyphens').
Parameter 'quantity' lacks constraints. No min/max specified. LLMs could pass 1000000, causing memory exhaustion or timeout. Should enforce quantity: 1 - 1000 with description: 'Number of IDs to generate (1 - 1000, default 1).'

Error handling returns plain text ('Error: <message>') without recovery guidance. Per pattern:recovery-guide, errors should suggest next steps. E.g., 'Invalid quantity: must be 1 - 1000' instead of generic error.
Parameter descriptions lack algorithm selection guidance. 'The ID generation algorithm to use' is generic. Should explain trade-offs: 'cuid2 (default): collision-resistant, distributed-friendly; uuid: standards-compliant; nanoid: URL-safe, compact; ulid: sortable by timestamp.'
