The MCP integration system prompt includes instructions for discovering and using tools and resources but does not mention prompts - the third primitive in the MCP protocol. This causes the agent to miss workflow triggers defined via MCP prompts.
Cursor supports MCP prompts, alongside tools and resources. But your point about the system prompt is interesting. If the agent can’t see the discovery prompt instructions, that could explain the issue.
Can you share a bit more detail:
Which MCP server are you using (name or a link to the config)?
Can you show an example of a prompt the agent was supposed to discover?
If you manually ask the agent to use a specific prompt, does it see it, or does it not recognize it at all?
That’ll help us understand how big the issue is and pass it to the team with concrete details.
