MCP prompts with slashes do not work

[mkschreder (Martin Schröder)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Any MCP prompt that has slash in it is not being requested by cursor from the mcp server. Something is wrong there inbetween.

Steps to Reproduce

• Have an MCP server with a prompt like “test/prompt”.
• Try to run the prompt in agent: /test/prompt

Model thinks: the user has provided a cryptic message that looks like a command.

Expected Behavior

The model should act according to the content of the prompt.

Operating System

Linux

Thanks for the detailed report!

Do MCP prompts without slashes work correctly? (e.g., test_prompt)
Can you check if the prompt is enabled in the Settings page?
