The Bug: Why Cursor Agent Terminal Doesn't Work with Powerlevel10k + Oh-My-Zsh

Cursor agent Terminal doesn't work—that’s the headline, but what’s really going on? Let’s break it down in my situation:

Common Symptoms:

Symptom When It Happens
Command never finishes in Cursor Agent Powerlevel10k + Oh-My-Zsh
Custom profile ignored Agent runs commands automatically
Works in manual terminal, not agent Only agent sessions affected

Why does this happen? Powerlevel10k’s advanced prompt features can interfere with how Cursor Agent detects command completion. The agent expects certain signals, but Powerlevel10k’s customizations can block or alter them.


Solution: Keep Powerlevel10k and Make Cursor Agent Terminal Work

You don’t have to ditch your favorite terminal theme. Here’s a step-by-step fix that keeps Powerlevel10k and restores Cursor Agent’s command detection:

Step 1: Download Shell Integration

curl -L https://iterm2.com/shell_integration/zsh -o ~/.iterm2_shell_integration.zsh

Step 2: Update Your ~/.zshrc

Add this snippet to your .zshrc so it only activates in Cursor Agent sessions:

if [[ -n $CURSOR_TRACE_ID ]]; then
  PROMPT_EOL_MARK=""
  test -e "${HOME}/.iterm2_shell_integration.zsh" && source "${HOME}/.iterm2_shell_integration.zsh"
  precmd() { print -Pn "\e]133;D;%?\a" }
  preexec() { print -Pn "\e]133;C;\a" }
fi

Step 3: Reload and Restart

source ~/.zshrc

Restart Cursor. Now, Powerlevel10k stays active in your normal terminal, but Cursor Agent gets the right signals to detect command completion. The CURSOR_TRACE_ID check ensures this only affects Cursor sessions.

{
  "mcpServers": {
    "API specification": {
      "command": "npx",
      "args": [
        "-y",
        "apidog-mcp-server@latest",
        "--oas=https://petstore.swagger.io/v2/swagger.json"
      ]
    }
  }
}

For Windows:

{
  "mcpServers": {
    "API specification": {
      "command": "cmd",
      "args": [
        "/c",
        "npx",
        "-y",
        "apidog-mcp-server@latest",
        "--oas=https://petstore.swagger.io/v2/swagger.json"
      ]
    }
  }
}

Step 4. Verify the Connection

After saving the config, test it in the IDE by typing the following command in Agent mode:

Please fetch API documentation via MCP and tell me how many endpoints exist in the project.

If it works, you’ll see a structured response that lists endpoints and their details. If it doesn’t, double-check the path to your OpenAPI file and ensure Node.js is installed properly.
