CodBi / AI Proxy — Authenticated reverse proxy to local LLAMA-server, Whisper-server, and

Tesseract OCR.

Servlet that proxies HTTP requests from authenticated external clients to local AI servers managed by LLAMA and Whisper, and to the in-process TesseractAction OCR engine. Provides IP-based access control, multi-user Basic Auth, and anonymised request logging into the Formcycle database.

Exposes the following endpoints through Formcycle's HTTP stack:

POST  /plugin?name=CodBi_AI_Proxy&endpoint=/v1/chat/completions
POST  /plugin?name=CodBi_AI_Proxy&endpoint=/completion
POST  /plugin?name=CodBi_AI_Proxy&endpoint=/v1/audio/transcriptions
POST  /plugin?name=CodBi_AI_Proxy&endpoint=/v1/ocr

LLAMA and Whisper requests are forwarded via HTTP to their respective local server processes. Tesseract requests are handled in-process via JNI (no external server) through TesseractAction.performOcr.

Security is enforced via:

• IP whitelist → plugin property AI_Proxy_AllowedIPs

• HTTP Basic Auth → plugin property AI_Proxy_Users

Every request is logged to the Formcycle database table codbi_ai_proxy with anonymised caller information (SHA-256 of username, first two octets of IP).
