Progressive-disclosure usage manual for Cloud Mail REST email actions. Read it when action filters/ids, setup/authentication, polling/settings, or side-effect detail is needed. Returned by action='manual'; nested references are packaged but not embedded. Calls use the strict LTP-v2 envelope.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cloud Mail MCP — usage manual (progressive disclosure) In the LingTai host, root `summarize` defaults to `true`; specify what to retain in `reasoning`. Proactively set `summarize=false` for verbatim manuals and mandatory gates, exact names/paths or message ids, field presence, source, diffs, or evidence. Summaries are lossy and noncanonical; raw results remain preserved. This is result presentation, not action input or Context compression. Cloud Mail is a REST client for a self-hosted Cloud Mail deployment, not IMAP or SMTP. Inbound mail is polled automatically and delivered to the host agent's inbox via LICC; you normally do not poll `check` just to receive notifications. Each notification already carries the current message (sender, subject, body preview, and an exact `message_ref` id) — do not call `check`, `search`, or `read` again merely to reread that same content or to recover an id already present in the notification; see [`reference/actions.md`](reference/actions.md) for exactly when a `read` recovery call is warranted. This file is the model-facing router. Load only the packaged reference that matches the question: | Need | Read | |---|---| …

How to install
mdr add lingtai-ai/lingtai-kernel/cloud-mail-mcp-manual@sha256:488e9d8b16a4f8bbThe line at the top of this page pins the label v1.4.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
