Integrations

PasteGuard works with any tool that supports the OpenAI API. Just change the base URL to point to PasteGuard.

​
Cursor

In Cursor settings, configure a custom OpenAI base URL:
  1. Open Settings → Models
  2. Scroll to API Keys section
  3. Enable Override OpenAI Base URL toggle
  4. Enter: 
    http://localhost:3000/openai/v1
  5. Add your OpenAI API key above
All requests from Cursor now go through PasteGuard with PII protection.

​
Chat Interfaces

​
Open WebUI

In your Docker Compose or environment: 
services:
  open-webui:
    environment:
      - OPENAI_API_BASE_URL=http://pasteguard:3000/openai/v1
      - OPENAI_API_KEY=your-key
Or point Open WebUI to PasteGuard as an “OpenAI-compatible” connection.

​
LibreChat

Configure in your librechat.yaml: 
version: 1.2.8
cache: true
endpoints:
  custom:
    - name: "PasteGuard"
      apiKey: "${OPENAI_API_KEY}"
      baseURL: "http://localhost:3000/openai/v1"
      models:
        default: ["gpt-5.2"]
        fetch: false
      titleConvo: true
      titleModel: "gpt-5.2"

​
Python / JavaScript

​
OpenAI SDK

from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:3000/openai/v1",
    api_key="your-key"
)

​
LangChain

from langchain_openai import ChatOpenAI

llm = ChatOpenAI(
    base_url="http://localhost:3000/openai/v1",
    api_key="your-key"
)

​
LlamaIndex

from llama_index.llms.openai_like import OpenAILike

llm = OpenAILike(
    api_base="http://localhost:3000/openai/v1",
    api_key="your-key",
    model="gpt-5.2",
    is_chat_model=True
)

​
Environment Variable

Most tools respect the OPENAI_API_BASE or OPENAI_BASE_URL environment variable: 
export OPENAI_API_BASE=http://localhost:3000/openai/v1
export OPENAI_API_KEY=your-key

​
Verify It Works

Check the response headers to confirm PasteGuard is processing requests: 
curl -i http://localhost:3000/openai/v1/chat/completions \
  -H "Authorization: Bearer $OPENAI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "gpt-5.2", "messages": [{"role": "user", "content": "Hi"}]}'
Look for: 
X-PasteGuard-Mode: mask
X-PasteGuard-Provider: upstream
