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 who work with model and prompt and want it reachable from 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`.

Using another client? Same JSON, different key
