Gatewards MCP server has 5 tools with basic descriptions and parameter schemas, but significant gaps in schema completeness, parameter documentation, and error handling. Tool names follow verb_noun convention (discover, call, check, get, subscribe), which is good. However, parameter descriptions are minimal or absent, input schemas lack proper type definitions for complex parameters, and output schemas are not documented. No error recovery guidance, no tool annotations, and no pagination support for discovery tools. The server addresses a specialized domain (API payment gateway) but lacks production-grade polish expected for A/B tier tools.

• Document output schemas for all tools. Example: gatewards_discover_services should return {services: [{service_id: string, name: string, description: string, endpoint: string, price: number}], total: number}. This enables tool chaining.
• Add nested schema definitions for 'params' in gatewards_call_api. Define it as {type: 'object', properties: {key: {type: 'string'}}, additionalProperties: true} or enumerate expected keys.
• Add pagination parameters (limit: 1-100, offset: 0) to gatewards_discover_services and gatewards_get_plans. Return total_count in responses.
• Expand parameter descriptions. 'search' in gatewards_discover_services should say 'Search term to filter services by name or description (case-insensitive, min 1 char)'. 'planId' should clarify format and where to find valid IDs.
• Add tool annotations: mark gatewards_call_api and gatewards_subscribe with destructiveHint=true; mark read-only tools with readOnlyHint=true. Include idempotentHint=true for gatewards_check_budget and gatewards_get_plans.
