# Promptibus MCP

> Model intelligence MCP for prompt syntax, pricing, and budget-aware picks.

- **Category:** Model Hubs
- **Vendor:** Promptibus (official)
- **Pricing:** freemium
- **Verified:** 2026-08-25

## What it does

Promptibus does not generate media; it gives agents current model profiles, pricing, parameters, prompt linting, and prompt optimization for image, video, audio, text, and code models. For filmmaker-agents spending across Runway, Sora, Veo, FLUX, Suno, Midjourney-style tools, and other fast-moving model families, it is a preflight layer that reduces stale syntax and expensive wrong-model choices.

## Field notes

MIT, npm @promptibus/mcp 0.9.0 — still the only release, published May 11 2026, and neither the package nor the repo has moved since; 3 stars. The hosted endpoint and the npx package both work, and anonymous mode needs no key at 25 calls/day and 500/month across 10 free-tier models. The staleness is the whole caveat, and it now shows on the vendor's own page: the free tier is still headlined by Claude 4 Sonnet, GPT-4o, DALL-E 3 and Midjourney v6.1. Confirm pricing and prompt syntax at the model vendor before you spend against its advice. It is a catalogue and preflight layer, not a generation router — nothing here renders a frame.
