About

What is just-prompt?

just-prompt is a lightweight Model Control Protocol (MCP) server designed to offer a unified interface to various leading Large Language Model (LLM) providers, including OpenAI, Anthropic, Google Gemini, Groq, DeepSeek, and Ollama. It simplifies interaction with these diverse models by providing a consistent API for sending prompts, either as direct text or from files. Key features include the ability to run multiple models in parallel, automatic model name correction, and the option to save responses to files. The tool also supports advanced reasoning controls for specific models, such as OpenAI o-series, Claude, and Gemini, allowing users to fine-tune the depth of internal reasoning or thinking tokens/budget. This makes it ideal for developers and data scientists looking to experiment with or integrate multiple LLMs efficiently.

Best used for

Ideal for developers and data scientists who need to interact with multiple LLM providers through a single interface, compare model responses, and experiment with advanced reasoning parameters. Especially valuable for building and testing multi-model AI applications or conducting research on LLM performance across different providers.

FAQs

Which LLM providers does just-prompt support?

just-prompt provides a unified interface for OpenAI, Anthropic, Google Gemini, Groq, DeepSeek, and Ollama. It allows you to interact with models from these providers using a consistent set of tools and commands.

Can I control the reasoning level of LLMs using just-prompt?

Yes, just-prompt supports advanced reasoning controls for specific models. For OpenAI o-series, you can append suffixes like ':low', ':medium', or ':high'. For Claude and Gemini, you can specify thinking tokens or budget using suffixes like ':1k' or ':4096'.

How do I set up just-prompt with my API keys?

You need to create a '.env' file in the just-prompt directory and populate it with your API keys for each provider (e.g., OPENAI_API_KEY, ANTHROPIC_API_KEY). The server will automatically detect available providers based on the keys provided.
