README
Prompt Rejector
**Screen prompts, skill files and MCP tool descriptions before an AI agent acts on them.**
Prompt Rejector combines deterministic security checks, focused **TypeSafe Jev judgments**, and a configurable reasoning model. The active configuration uses TypeSafe and Gemini; Claude and OpenAI adapters are available through model configuration.
| Use it from | Connection | Start command |
|---|---|---|
| An application or script | HTTPS API: https://localhost:3001 |
npm start |
| Codex / Claude Code | Plugin + MCP over stdio | Install the plugin or configure the Node launcher |
| Claude Desktop chat | Bundled .mcpb extension + skill |
Desktop installation |
| ChatGPT / Claude web | Skill + tunnel or authenticated remote MCP | Web connection guide |
The local API and MCP connections can run together and use the same analysis configuration. Prompt checks use **`POST /v2/check-prompt`**. `/v2` is the only current API; `/v1` is retired. MCP keeps all 11 tool names and needs no version selector.
**Already using Bryan's local installation?** The HTTPS service and Codex MCP entry are configured. Go to the [local service runbook](https://github.com/revsmoke/promptrejectormcp/blob/codex/typesafe-model-routing/docs/operations/local-server.md#installed-macos-service) for status and restart instructions; do not start a second server on port 3001.
