Server has 6 tools with complete input schemas and descriptions. Naming follows verb_noun convention (generate_, get_, render_, frames_, upload_, meshy_). Descriptions are detailed (100-300 chars) and explain WHAT, WHEN, and side effects. However, output schemas are not formally documented in the code, only inferred from docstrings. Parameters have types and descriptions, but some lack constraints (e.g., timeout, frames, resolution lack explicit min/max in schema). Error handling is minimal, no recovery guidance or categorization. Security is reasonable (API keys via env vars), but no permission gates or audit logging visible. Tool composition is sound: each does one thing, and outputs chain to inputs (e.g., generate_3d_model → glb_path → render_turntable). The meshy_to_youtube tool is a high-level orchestrator that combines five lower-level tools, good for user convenience but risks masking partial failures.

• Add explicit JSON Schema output definitions for all tools. Document return types as structured objects with typed fields (e.g., {"ok": boolean, "watch_url": string, "error": string, "failed_stage": string}).
• Add minValue, maxValue, and pattern constraints to numeric and string parameters in the schema. E.g., timeout: {type: integer, minimum: 1, maximum: 3600}.
• Enhance error messages with actionable recovery steps. E.g., 'MESHY_API_KEY not set. Set it via: export MESHY_API_KEY=your_key' or 'Blender not found on PATH. Install from https://www.blender.org/download/'.
• Add a dry_run parameter to upload_to_youtube and meshy_to_youtube to preview the operation without publishing. This prevents accidental public uploads.
• For meshy_to_youtube, document which intermediate artifacts are retained on failure (e.g., .glb, PNG frames) so agents can retry or inspect partial results.
