Setup
1. Generate an API key
Go to pretty-prompt.com/settings/mcp and create an API key.
2. Build
npm install
npm run build3. 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 |
| Yes | — | API key from settings ( |
| No |
| FastAPI backend URL |
| No |
| Supabase project URL |

Analytics
The MCP server sends PostHog events (fire-and-forget) for:
Event | When |
| Each time the server process starts and authenticates |
| First successful connection for an API key on this machine |
| Each tool invocation (name, success, duration, sanitized params) |
Events are attributed to the user's email from the MCP access token. Prompt text is never sent — only lengths and flags.
Disable locally with PRETTY_PROMPT_ANALYTICS=false.
Override env vars to point at local services:
PRETTY_PROMPT_BACKEND_URL=http://0.0.0.0:8000
PRETTY_PROMPT_SUPABASE_URL=http://127.0.0.1:54321Ensure the backend has SUPABASE_JWT_SECRET set and the mcp_api_keys
migration is applied.
