Prompts in the client

MCP Client and Prompt Management

Client Functionality:

• List Prompts: The client can retrieve a list of all defined prompts from the MCP server.
• Get Prompt: The client retrieves a specific prompt by providing its name and necessary arguments.
• The client passes the prompt name and arguments to the server session.
• The function returns the prompt's messages, which are used to form the conversation fed to the LLM/Cloud.

Prompt Mechanics and Variables:

• Prompt Definition: Prompts are defined within the MCP server and are designed to perform specific tasks (e. g. , document rewriting).
• Arguments/Variables: When requesting a prompt, arguments (e. g. , a document ID) are provided.
• Interpolation: These arguments are passed to the prompting function as keyword arguments and are then used to dynamically insert values into the prompt itself.

Workflow Example (Document Reformatting):

• Invocation: A user invokes a prompt (e. g. , format) via the CLI, providing necessary inputs (e. g. , a document ID).
• Instruction Delivery: The prompt, which contains the user's instructions and the document ID, is sent to the LLM/Cloud.
• Tool Usage: The LLM receives the instructions and the ID, and uses a designated tool (e. g. , get document tool) to fetch the document's content.
• Output: The LLM processes the fetched content according to the prompt's instructions and returns the final, reformatted output.

Conceptual Recap:

• The process begins by writing and evaluating a prompt relevant to the server's purpose.
• The prompt is defined within the MCP server.
• The client requests the prompt, supplying arguments as keyword inputs.
• The prompt function utilizes these keyword arguments to customize the final prompt.

Takeaways

• MCP Clients retrieve and execute prompts that are defined and managed within the MCP Server.
• Arguments are passed by the client and used for dynamic interpolation, customizing the prompt's content.
• The LLM processes the final prompt by utilizing designated tools (e. g. , fetching document content) based on the instructions.
• The workflow involves the client supplying keyword inputs to the server-side prompt function for execution.
