Just Prompt for Cursor: Setup & Config

Cursor: Just Prompt lets an MCP assistant consult several language models and preserve their answers.

What you can do with Just Prompt in Cursor

Keep model comparison, saved answers, and a panel's final decision within one MCP workflow.

  • Ask a designated decision model to weigh a panel's responses.
  • Discover provider-specific model choices before composing a multi-model request.

Before you start: Just Prompt in Cursor

  • Python and uv
  • Local checkout with dependencies prepared using uv sync
  • Credentials for chosen hosted providers, or an Ollama endpoint

This is the minimal README launch, not uv sync alone, which only prepares dependencies. The dot refers to the checkout directory; use the checkout's path if the client starts elsewhere. Provider values can be supplied by environment or .env. The optional --default-models argument chooses fallback models.

Just Prompt Cursor configuration

  1. Choose Cursor configuration scope

    For Just Prompt, open Project: .cursor/mcp.json User: ~/.cursor/mcp.json. Merge into mcpServers at project or user scope.

  2. Add Just Prompt to Cursor

    Use the just-prompt entry below in mcpServers. Keep Just Prompt's documented stdio connection fields and your other Cursor entries.

  3. Check Just Prompt in Cursor

    Just Prompt: Enable in Cursor’s MCP settings; inspect tools.

Just Prompt tools available to Cursor

Just Prompt's stored tool list documents 6 tools; compare it with Cursor's connected tool list, because the stored list is not a live check.

Find ceo_and_board under Just Prompt in Cursor's MCP settings; inspect its arguments when the agent requests a call.

prompt_from_file_to_file

Find prompt_from_file_to_file under Just Prompt in Cursor's MCP settings; inspect its arguments when the agent requests a call.

prompt_from_file

Find prompt_from_file under Just Prompt in Cursor's MCP settings; inspect its arguments when the agent requests a call.

prompt

Find prompt under Just Prompt in Cursor's MCP settings; inspect its arguments when the agent requests a call.

Submit text directly to a chosen model set, falling back to configured models when omitted.

list_models

Find list_models under Just Prompt in Cursor's MCP settings; inspect its arguments when the agent requests a call.

Discover model choices under one specified provider.

list_providers

Find list_providers under Just Prompt in Cursor's MCP settings; inspect its arguments when the agent requests a call.

Troubleshooting Just Prompt in Cursor

  • Cursor must find uv for Just Prompt. Enable the project/user entry in MCP settings and inspect its tools.
  • Review ANTHROPIC_API_KEY, DEEPSEEK_API_KEY, GEMINI_API_KEY, GROQ_API_KEY, OLLAMA_HOST, OPENAI_API_KEY for Just Prompt before sharing project .cursor/mcp.json; project scope travels with the repository.
  • Just Prompt uses stdio here: Cursor must keep the configured process running; protocol output belongs on stdout and diagnostics on stderr.
  • Known limitation: File-based operations require absolute prompt and output paths.
  • Known limitation: Each hosted backend needs its own usable credential.
  • Known limitation: Reasoning suffixes are tied to documented models and provider-specific limits.
  • General Cursor troubleshooting lives in the /clients/cursor guide.

Frequently asked questions

Cursor's Just Prompt entry belongs under mcpServers in .cursor/mcp.json (project) or ~/.cursor/mcp.json (user). Confirm the active scope in MCP settings.

Cursor's just-prompt example uses stdio.

Just Prompt's Cursor configuration invokes uv.

Cursor's Just Prompt example references ANTHROPIC_API_KEY, DEEPSEEK_API_KEY, GEMINI_API_KEY, GROQ_API_KEY, OLLAMA_HOST, OPENAI_API_KEY. Check these names if startup or authentication fails; the example alone does not distinguish required from optional values.

Just Prompt's stored list contains 6 tools, including ceo_and_board, prompt_from_file_to_file, prompt_from_file. Compare those names with Cursor's connected tool list; the stored list is not a live check.

No. Startup reports providers with missing keys as unavailable while allowing use of the providers whose credentials are available.
