Promptibus MCP

Model intelligence for AI agents - syntax, params, pricing for 67+ generative AI models. This MCP entry surfaces a curated ranking/list from the project README rather than a classic multi-tool integration surface. It still exposes 7 documented tools (including recommend_model, optimize_prompt, lint_prompt) for browsing or selecting items from that list.

People connecting AI & ML tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

01 · Install Promptibus MCP

before you install - you'll need

Set PROMPTIBUS_API_KEY before connecting.

Claude Code

claude mcp add promptibus-mcp -- npx -y @promptibus/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "promptibus-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@promptibus/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
