Common Issues

Problem: The mcp.json file doesn’t exist in the expected location.Solution: You can create the file manually. The mcp.json file should be located at:
  • macOS (Cursor): ~/.cursor/mcp.json
  • macOS (Windsurf): ~/.windsurf/mcp.json
  • macOS (Claude Desktop): ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows (Cursor): %APPDATA%\Cursor\mcp.json
  • Windows (Windsurf): %APPDATA%\Windsurf\mcp.json
  • Windows (Claude Desktop): %APPDATA%\Claude\claude_desktop_config.json
  • Linux (Cursor): ~/.config/cursor/mcp.json
  • Linux (Windsurf): ~/.config/windsurf/mcp.json
Create the directory if it doesn’t exist, then create the mcp.json file with the configuration from the installation guide.Example:
# For Cursor on macOS
mkdir -p ~/.cursor
touch ~/.cursor/mcp.json
Then add the configuration:
{
  "mcpServers": {
    "nia": {
      "command": "pipx",
      "args": ["run", "--no-cache", "nia-mcp-server"],
      "env": {
        "NIA_API_KEY": "YOUR_API_KEY",
        "NIA_API_URL": "https://apigcp.trynia.ai/"
      }
    }
  }
}
Problem: After installation, the Nia tools don’t appear in your MCP client (Cursor, Claude Desktop, etc.).Solution: This usually happens when the MCP server isn’t installed globally. Make sure you’ve installed using pipx for global installation:
# Install pipx first if you haven't
pip install pipx

# Install nia-mcp-server globally
pipx install nia-mcp-server
Why pipx is recommended:
  • pipx installs packages globally in isolated environments
  • Tools are available system-wide
  • No conflicts with other Python packages
  • Automatic PATH management
After installing with pipx:
  1. Update your MCP configuration to use pipx run
  2. Restart your MCP client completely
  3. Check if tools appear in the MCP tools section
If you previously installed with pip, uninstall first:
pip uninstall nia-mcp-server
pipx install nia-mcp-server
Problem: Getting an error that no API key was provided.Solution:
  1. Ensure you’ve replaced YOUR_API_KEY with your actual API key from app.trynia.ai
  2. Check that the environment variable is correctly set in your MCP configuration
  3. Verify there are no typos in the environment variable name NIA_API_KEY
  4. Make sure there are no extra spaces or hidden characters in your API key
Example of correct configuration:
{
  "mcpServers": {
    "nia": {
      "command": "pipx",
      "args": ["run", "--no-cache", "nia-mcp-server"],
      "env": {
        "NIA_API_KEY": "sk-proj-abc123xyz789",  // Replace with your actual key
        "NIA_API_URL": "https://apigcp.trynia.ai/"
      }
    }
  }
}
Problem: Getting “command not found” when trying to use pipx.Solution: Install pipx first:
# On macOS with Homebrew
brew install pipx
pipx ensurepath

# On Windows
pip install pipx
pipx ensurepath

# On Linux
pip install pipx
pipx ensurepath
After installation, you may need to:
  1. Restart your terminal
  2. Add pipx to your PATH if not done automatically
  3. Verify installation with pipx --version
Problem: Getting rate limit errors when using Nia tools.Solution:
  • You’ve used your allocated requests for the current period
  • Check your usage at app.trynia.ai
  • Consider upgrading your plan for more requests
  • Free tier includes 3 indexing jobs and limited searches
Problem: The GitHub app installation doesn’t complete or gets stuck during onboarding.Solution:
  1. Go to GitHub → Settings → Applications → Installed GitHub Apps
  2. Find and remove the Nia app
  3. Return to app.trynia.ai and restart the onboarding process
You don’t have to give Nia access to your own repositories. The GitHub app connection is only used to avoid GitHub’s API rate limits when indexing public repositories. You can skip granting access to personal repos entirely.
