HTTP API

The UI talks to the Moka server over a small JSON API. You can use it too — for scripted demos, CI smoke tests or your own front end.

Auth: send the token printed at startup as x-moka-token: <token> (or ?token=). GET /api/health needs no token.

TOKEN=...   # from the startup URL
curl -s -H "x-moka-token: $TOKEN" localhost:4000/api/bootstrap | jq .config.llms

Chat

POST /api/chat streams NDJSON — one JSON object per line.

curl -N -H "x-moka-token: $TOKEN" -H 'content-type: application/json' \
  -d '{"messages":[{"role":"user","content":"What time is it in Tokyo?"}]}' \
  localhost:4000/api/chat

Body field
`messages`	AI SDK `ModelMessage[]` — the full history
`workspaceId`	Optional; defaults to the active workspace
`llmId`	Optional; override the workspace’s model
`agentId`	Optional; talk to this remote agent instead

Chunk `type`	Fields
`start`	`runId`, `model`, `profileId`, `tools` (count)
`text` / `reasoning`	`text` (delta)
`tool-call`	`id`, `name`, `tool`, `source`, `input`
`tool-result`	`id`, `output`, `isError`, `durationMs`, `ui?`, `raw?`
`step`	`usage`, `finishReason`
`finish`	`usage`, `durationMs`, `messages` — append these to your history for the next turn
`error`	`message`

ui is one of {kind:"mcp-app", serverId, resourceUri}, {kind:"mcp-ui", …} or {kind:"a2ui", messages}.
