pasteguard — Local Privacy Proxy for AI Tools

Main

• Treat PasteGuard as a drop-in reverse proxy: you change the base URL once, and it masks secrets/PII before the request leaves your machine.

• Use it both for chat and coding tools: the proxy path supports OpenAI-style /v1 routing and a dedicated /anthropic endpoint.

• If you need higher privacy, enable the project’s “route mode” idea: sensitive requests can be routed to a local model while non-sensitive traffic goes to a hosted provider (see docs).

Source-backed notes

• README Quick Start runs a local proxy container on port 3000 and shows base URLs like http://localhost:3000/openai/v1.
• README claims it detects 30+ types of sensitive data across 24 languages and keeps data on-device.
• README includes a Claude Code example using ANTHROPIC_BASE_URL=http://localhost:3000/anthropic.

FAQ

• Does it require code changes?: Usually no — you swap the provider base URL to the localhost proxy and keep the rest the same.
• What does it mask?: README highlights names, emails, and API keys; masking behavior depends on its detection engine and config.
• Can I use it with Claude Code?: Yes — README shows routing Anthropic requests via ANTHROPIC_BASE_URL to the local proxy.
