DaxOps MCP demonstrates solid tool design with clear naming conventions (verb_noun pattern), comprehensive parameter schemas using Zod, and detailed descriptions. All 11 tools are explicitly registered with inputSchema and descriptions. Tool annotations (readOnlyHint, openWorldHint) are present. However, output schemas are not formally documented, responses are formatted as text summaries rather than structured JSON objects. Error handling exists but lacks recovery guidance in several tools. Parameter descriptions are generally good (60-150 chars) but some lack format constraints (e.g., brandColor accepts '#RRGGBB' but this is only mentioned in description, not as a regex pattern). The server handles async polling and file I/O well, but destructive operations (daxops_delete_dashboard) lack confirmation patterns.

• Convert text-formatted responses to structured JSON. daxops_list_solutions should return {solutions: [{id: string, title: string, industry: string, description: string, kpis: string[]}]} instead of a formatted text summary. This enables agents to extract and chain data reliably.
• Add a daxops_confirm_delete_dashboard tool or require a confirmation parameter (e.g., confirmed: boolean) on daxops_delete_dashboard. Destructive operations should never execute without explicit agent intent.
• Formalize parameter constraints in JSON Schema. Add pattern: '^#[0-9A-Fa-f]{6}$' to brandColor parameters. Add enum constraints to theme and pages parameters where applicable.
• Enhance error responses with structured classification. Return {error: string, code: 'RETRYABLE'|'USER_FIXABLE'|'FATAL', suggestion: string} so agents know whether to retry, ask the user, or abort.
• Add explicit timeout handling to pollJob(). Set a max poll duration (e.g., 5 minutes), return a timeout error with the job ID, and document that agents can call daxops_download later to retrieve the result.
