Desktop App for monitoring and controlling llm requests (with focus on coding agents)
Fully local (on-device), desktop app for
- block or get notified on high request or token usage by agents
- searchable complete history for LLM requests by agents
- pass-through proxy server for LLM requests
- block or redact requests with sensitive information (pre-defined and user-defined patterns)
- codex, claude, cursor supported out of the box with tool call and token monitoring
How it works
- codex and claude code: Codex and Claude Code support a configurable base URL, which lets LLMWatcher route all requests through its local server.
- cursor: Cursor has limited hooks that LLMWatcher uses to block or monitor requests (auto-redaction and exact token counts are not supported).
Custom LLM endpoints
- In the app, you can configure a custom chat completions endpoint
- This feature is useful if you are using your own token with a LLM endpoint, and you want to monitor / control data
Detections
- Block or Redact data going to LLMs automatically with intelligent pattern matching
- Pre-defined patterns for general use cases (API Keys, credentials, etc)
