GoPress MCP demonstrates solid naming conventions with clear verb-noun structure (get, list, create, update, publish, move_to_trash, restore). All 12 tools have descriptions present and mostly adequate (ranging 50-200 chars, meeting baseline of 194 chars average). Input schemas are fully defined with proper JSON Schema types and per-parameter descriptions. However, output schemas are not documented, a critical gap for agent planning. Error handling is basic; no explicit error classification or recovery guidance visible. Tool composition is good (single responsibility per tool), and field naming is consistent (content_type, expected_updated_at). Security patterns (optimistic locking, explicit confirmation for destructive ops) are well-implemented. The main weakness is lack of documented response structures and output field mapping needed for tool chaining.

• Document output schema for every tool. For list tools, specify: result type (array of objects), fields in each object (content_type, id, title, status, updated_at, etc.), total_count, has_more, next_page_token. Example: 'Returns {items: [{id: uint, title: string, status: string, updated_at: string, ...}], total_count: uint, has_more: bool}'.
• Add error handling guidance to tool descriptions. Example: 'If content_type is invalid, returns 400 with message listing available types. If content not found, returns 404 with suggestions (Did you mean: post_123, post_456?).'
• For meta field in create_draft and update, specify allowed keys and value types. Example: 'Custom metadata as key-value pairs (string keys, string or number values). Reserved keys: _internal_* (read-only).'
• Explicitly state result limits in descriptions: 'Returns up to 50 items per page. Use page parameter to fetch additional results. Pagination is bounded: max 1000 items accessible.'
• Clarify confirm parameter behavior: 'When confirm=false, returns a dry-run preview (no action taken). When confirm=true, executes irreversibly. publish changes content.status to published; move_to_trash changes status to trash.'
• Add field-naming consistency checks: ensure that all content lookup tools (get, list) return content_id (not id), content_type (not type), so downstream tools (update, publish) can chain IDs without field name translation.
• Consider adding a discover_content_types tool or enriching site.get to return the full list of available content_types upfront, reducing need for separate content_types.list call in agent planning.
