Chat directly with a Project (no Agent needed): its Prompts become the system
context, its MCP-server tools are callable, its llmProvider/llmModel drive the
LLM, and (opt-in) the model can read secret values. History is saved inside the
project, attributed per user, resumable, and deletable (RBAC-permitting) — "use
it like Claude, scoped to the project".
Backend (reuses the agent-chat orchestrator):
- ChatThread is now agent-XOR-project (schema + migration + CHECK constraint);
new listThreadsByProject / deleteThread on the repo.
- ChatService: prepareProjectContext (project prompt + Prompts by priority,
llm from llmProvider with llmModel override, project tools), shared
runChatLoop/runChatStreamLoop, project thread CRUD with owner enforcement
(404-not-403 on foreign threads), admin-override delete.
- Gated get_secret virtual tool: offered only with --allow-secrets AND the
caller's view:secrets; resolves via SecretService, never routes to a server.
- routes/project-chat.ts (chat SSE+non-stream, threads create/list/delete);
RBAC run:projects:<name>.
CLI:
- `mcpctl chat --project <name>` (+ --allow-secrets), one-shot/REPL/resume.
- REPL /threads, /resume <id>, /delete <id>; project-aware header + /tools.
- `mcpctl get threads --project <name>`, `mcpctl delete thread <id> --project`.
- completions regenerated (--project completes project names).
Tests: 8 new project-chat unit tests; full mcpd (945) + CLI (508) green;
schema validated against Postgres. Docs: docs/chat.md "Project chat" section.
