Prompts

Prompts are reusable instruction templates exposed to MCP clients, so an AI assistant can pull a vetted prompt instead of everyone re-writing the same instructions by hand.

What you can do

• Maintain a shared prompt library, independent of any single server, with its own creation wizard and tags.
• Link any prompt from the shared library into a specific server, so the same prompt can be reused across multiple servers without duplicating it.
• Use placeholders like {{argumentName}} in a prompt's content — Arthur automatically detects the arguments a prompt expects and exposes them to the AI client.
• Start from a curated Prompt Template instead of writing one from scratch.
• Enable or disable a linked prompt per server, controlling whether the AI client and the public documentation page see it.

How to use it

1. Go to Prompts to create or browse the shared library, or start from Prompt Templates.
2. Write the prompt content, using {{argumentName}} for anything the caller should fill in.
3. Open a server and, on its Prompts tab, link the prompt you want available there.
4. Enable the linked prompt once it's ready for AI clients.

Good to know

• One prompt, many servers: editing the shared prompt updates it everywhere it's linked.
