Promptibus MCP — Claude Code MCP server: what it does, how to install
Provides AI coding agents with verified syntax, parameters, and dollar pricing across 67+ generative AI models. Prevents wasted generation credits and invalid prompt parameters.
claude mcp add --env PROMPTIBUS_API_KEY=<PROMPTIBUS_API_KEY> --env PROMPTIBUS_API_URL=<PROMPTIBUS_API_URL> --transport stdio promptibus-mcp -- npx -y @promptibus/mcpWhat Promptibus MCP does
Coding assistants often rely on outdated training data when constructing generative media prompts. Agents stop guessing parameters. This server supplies live specifications for 67 models spanning video and image generation.
Prompt preparation tools catch issues before sending payloads to upstream APIs. Calling lint_prompt flags deprecated arguments and formatting errors. Meanwhile, get_pricing estimates volume expenses in USD and highlights more economical substitutes.
Anonymous setups get 25 calls per day across 10 common models. Querying the complete catalog of 67 models requires a subscription and a valid PROMPTIBUS_API_KEY. Without Node.js or npx, standard stdio initialization will fail.
What it helps with
- select suitable generative models for audio, video, or image tasks
- detect obsolete syntax and parameter errors before running generations
- recalculate prompt phrasing to match specific model versions
- estimate USD generation costs and identify cheaper alternative models
Example prompts for the agent
- Run lint_prompt on my Suno v4 prompt and remove deprecated structure tags
- Check get_pricing for generating 500 images with dall-e-3 and suggest cheaper alternatives
- Recommend the top models for rendering a 30-second storm sequence using recommend_model

Questions about Promptibus MCP
How do I install Promptibus MCP in Claude Code?
Run claude mcp add mcp -e PROMPTIBUS_API_KEY=<PROMPTIBUS_API_KEY> -- npx -y @promptibus/mcp in your terminal. Replace <PROMPTIBUS_API_KEY> with your personal token.
What does Promptibus MCP do?
The server exposes tools that evaluate prompt syntax, track current pricing, and inspect parameters for generative AI models. It keeps agents from submitting invalid flags or exceeding project budgets.
Can I run Promptibus MCP without an API key?
Yes, anonymous access operates without an account or key. It allows 25 daily queries across 10 basic models, resetting every day at midnight UTC.
