Stripe server has clear verb-based naming and reasonable descriptions (avg 150 chars), but lacks critical depth. All 6 tools have input schemas with types and descriptions, meeting baseline requirements. However, output schemas are undocumented (tools return JSON strings without field documentation), parameter constraints are minimal (no enums, ranges, or validation guidance), and error handling is generic. No tool annotations (readOnlyHint/destructiveHint). The create_payment_link tool is marked WRITE but lacks confirmation/dry-run pattern. Missing dependency hints and recovery guidance. Descriptions are adequate but not LLM-optimized per pattern:tool-description (should be 50-200 chars; most are 100-180, acceptable but could be tighter).

• Document output schemas for all tools. E.g., get_balance returns {available: {[currency]: string}, pending: {[currency]: string}}. Include field types and meanings.
• Add tool annotations: mark read-only tools with readOnlyHint=true; mark create_payment_link with destructiveHint=true.
• Implement confirmation pattern for create_payment_link: add a 'dry_run' parameter or require explicit confirmation before creating links.
• Add JSON Schema constraints: limit (minimum: 1, maximum: 100), days (minimum: 1, maximum: 365), active_only as boolean enum.
• Enhance error messages with recovery guidance: 'Stripe not configured. Set STRIPE_SECRET_KEY environment variable and restart the server.' Include actionable next steps.
