This server provides a modest Netlify integration with 4 tools that expose basic CRUD operations on sites. Tool naming follows the verb_noun convention reasonably well (createSiteFromGitHub, listSites, getSite, deleteSite). Descriptions exist for all tools and are substantive (14 - 50 words). Input schemas are properly defined with JSON Schema and include required/optional fields. However, critical gaps emerge: (1) Output schemas are entirely undocumented, the response structure for each tool is absent from the definitions, forcing LLMs to infer what fields will be returned. (2) Parameter descriptions lack actionable constraints, e.g., 'repo' accepts 'owner/repo' format but provides no validation guidance or error recovery hints. (3) deleteSite has no confirmation mechanism despite being irreversible. (4) Error handling in the implementation includes formatNetlifyError() but error responses are not structured in a way visible to LLMs in the schema. (5) Missing dependency hints and multi-step guidance, e.g., createSiteFromGitHub requires a valid GitHub repo, but there's no hint to validate or search repos first. The implementation is solid (axios with proper timeouts, environment variable injection), but the schema layer lacks the LLM-optimization depth needed for reliable multi-step workflows.

• Add explicit output schemas to all tools. For createSiteFromGitHub, document: { site_id: string, site_name: string, site_url: string, admin_url: string, deploy_status: enum, created_at: string (ISO 8601) }. Without this, LLMs cannot chain to getSite or track created resources.
• Expand tool descriptions to 50 - 200 characters, following the prompt-engineering pattern: 'Converts X to Y when you want Z. Returns [key fields].' Example: 'List all Netlify sites you can access (filter by owner/guest access). Returns paginated list with site IDs, names, and deploy URLs. Use before calling getSite to discover available sites.'
• Add a confirm_delete_site tool or convert deleteSite to accept a 'confirm: true' required parameter. Document: 'This action permanently removes the site and all deployments. Cannot be undone. Pass confirm=true to proceed.' Implement as a two-step: first call returns a confirmation_token; second call (with token + confirm=true) executes deletion.
• Document parameter constraints formally: 'repo must match pattern ^[\w.-]+/[\w.-]+$ (e.g., owner-name/repo-name). If invalid, a 400 error is returned; check repo name in GitHub and retry.' Apply the same rigor to perPage (must be 1 - 100).
• Add dependency hints in descriptions. E.g., createSiteFromGitHub: 'Requires a valid GitHub repo token in the account settings. If deployment fails, call getSite to check build logs.' listSites: 'Returns a paginated list. If you know the site name, call getSite directly to avoid iterating.'
• Clarify siteId resolution precedence in getSite and deleteSite descriptions: 'The siteId parameter accepts either a site UUID (e.g., abc123def456) or a site name (e.g., my-site). If both exist, UUID takes precedence. To find a site by partial name, use listSites first.'
