Description

Overview

My company hosts an MCP server that provides prompts over MCP. We noticed something strange in our metrics because we saw a massive spike in usage, equally across all prompts.

Problem

This is coming from OpenCode. Upon starting a new session, OpenCode is fetching ALL prompts on the server.

Then, when a user wants to run one of the remote prompts and types in /<server-name>:<prompt-name> and presses enter, OpenCode once again makes a request to fetch the prompt from the server.

Expected behavior

OpenCode should fetch the prompt from the server when the user types / and then hits enter to run that prompt. This is necessary because prompts over MCP support arguments, and the server is responsible for injecting those arguments into the prompt and returning the fully constructed prompts.

Prompts should not be fetched when OpenCode initializes.

Plugins

No response

OpenCode version

latest

Steps to reproduce

  1. Add an MCP server which hosts prompts
  2. open OpenCode
  3. monitor traffic and see that a GET request fired for every prompt on the server
  4. run one of the prompts manually
  5. monitor traffic and see that a new GET request fired to the server for that prompt
