Setup

1. Generate an API key

Go to pretty-prompt.com/settings/mcp and create an API key.

2. Build

npm install
npm run build

3. Configure Cursor

Add to your Cursor MCP config (~/.cursor/mcp.json or project .cursor/mcp.json):

{
  "mcpServers": {
    "pretty-prompt": {
      "command": "npx",
      "args": ["-y", "@pretty-prompt/mcp@latest"],
      "env": {
        "PRETTY_PROMPT_API_KEY": "pp_mcp_..."
      }
    }
  }
}

For local development, override the production defaults:

"env": {
  "PRETTY_PROMPT_API_KEY": "pp_mcp_...",
  "PRETTY_PROMPT_BACKEND_URL": "http://0.0.0.0:8000",
  "PRETTY_PROMPT_SUPABASE_URL": "http://127.0.0.1:54321",
  "PRETTY_PROMPT_SUPABASE_ANON_KEY": "your-local-anon-key"
}

Environment variables

Variable	Required	Default	Description
PRETTY_PROMPT_API_KEY	Yes	—	API key from settings (pp_mcp_...)
PRETTY_PROMPT_BACKEND_URL	No	https://production.pretty-prompt.com	FastAPI backend URL
PRETTY_PROMPT_SUPABASE_URL	No	https://api.pretty-prompt.com	Supabase project URL
PRETTY_PROMPT_SUPABASE_ANON_KEY	No	Production anon key	Supabase anon key

Local development

Override env vars to point at local services:

PRETTY_PROMPT_BACKEND_URL=http://0.0.0.0:8000
PRETTY_PROMPT_SUPABASE_URL=http://127.0.0.1:54321

Ensure the backend has SUPABASE_JWT_SECRET set and the mcp_api_keys migration is applied.
