MCA v0.1.0-alpha.2

MCA v0.1.0-alpha.2

Local API compatibility update for the public alpha line.

Highlights

• Verified OpenAI-compatible local API use with a third-party Android client.
• Improved /v1/chat/completions compatibility for common connection tests:
  multiple system messages are normalized and probes without a user turn no
  longer fail local chat templates.
• Improved streaming detection for stream=true, string/number stream flags,
  and Accept: text/event-stream.
• Confirmed SSE responses with data: {...} chunks and final data: [DONE].
• Added foreground keep-alive support for the local API server while it is
  enabled.
• Added cloud multimodal chat input support by sending image attachments to
  OpenAI-compatible and Anthropic-compatible vision models.
• Added experimental local vision support for llama.cpp multimodal GGUF models
  that have a matching mmproj / vision projector file.
• Expanded the in-app API Usage Guide with Base URL guidance, supported paths,
  stream behavior, error explanations, and trusted-network safety notes.
• Updated GitHub documentation for local API setup and compatibility.

Local API Notes

Use http://127.0.0.1:11435/v1 for same-device clients.

Use http://<phone-lan-ip>:11435/v1 for another trusted device on the same
network, after enabling open port inside MCA.

Supported paths:

• GET /health
• GET /v1/models
• POST /v1/chat/completions
• GET /

The API key is generated inside MCA and should not be shared in issues,
screenshots, or release notes.

Known Limits

• A local chat model must be loaded before chat requests can complete.
• Same-LAN open port should only be used on trusted networks.
• Local vision requires a matching multimodal GGUF model and projector file;
  text-only GGUF models cannot identify images.
• Local image generation remains experimental and should not be presented as a
  stable fast phone-side feature yet.
