## 2026-10-31 — REST API fixes

- `resources/list` and `resources/get` now respond: their schema describes a resource's real fields (version 2.0.0)
- `analytics/profiling-report` now responds with the agent's profiling fields, and a field that does not exist returns a 404 with its code instead of a 500
- `appointments/list` and `appointments/stats` are no longer advertised in `/openapi.json` while they are unavailable, instead of answering with a 500
- `/openapi.json` advertises `https://api.watsi.ai` as its server

## 2026-10-30 — Attach files from MCP and the API

- New MCP tools and REST endpoints `attachment_create_upload`, `attachment_finalize` and `attachment_import_url` to upload files to Resources, to a property's photos, floor plan and brochure, and to the knowledge base
- From an AI chat, a public `https://` link is enough; from a client that makes HTTP requests, a signed upload URL
- `add_agent_knowledge` now only downloads public `https://` links and refuses private or local addresses
