A developer shared how they transformed their product's media generation pipeline into an MCP Server with 29 tools, enabling a single chat to scrape web pages, generate images, upscale, and create videos.
Core Design Highlights:
- Discovery Tools: Offers findmodel and similar utilities, allowing agents to navigate a massive model catalog and match valid parameters before generation.
- Spend Guardrails: Enforces free estimatecost and parameter validation before any billed action, requiring the model to explicitly state costs. A webhook liveness probe ensures failed requests cost zero.
- Auth & Security: Uses OAuth 2.1 + PKCE for native Claude/Cursor integration. User IDs are injected from tokens, preventing privilege escalation and prompt injection.
- Privacy & Scaling: Logs only parameter shapes instead of sensitive content, scaling horizontally via stateless HTTP workers.
