Add a self-hosted or cloud Mattermost bot channel through the Chat SDK bridge, reusing a healthy server when available and linking to official server setup guidance when needed.
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
# Add Mattermost Channel Adds Mattermost DMs, channels, threads, files, reactions, and interactive approval cards. Messages arrive over Mattermost's WebSocket; card clicks return to NanoClaw over an authenticated HTTP callback. Every step is safe to re-run. ## Discover the server first Do this before installing the adapter or asking for a URL. The goal is to reuse a healthy Mattermost the user already has and establish one canonical base URL. 1. Check an existing `MATTERMOST_BASE_URL` in the current environment and NanoClaw env/config files. Do not print tokens or dump whole env files. 2. Probe likely local URLs, at least `http://localhost:8065` and `http://127.0.0.1:8065`, using `GET /api/v4/system/ping`. A listening port alone is not evidence that the service is Mattermost. 3. Inspect Docker/Compose for Mattermost containers. If a matching container exists but is stopped, offer to start it with its original mechanism; do not start or recreate it without the user's approval. 4. If you find a healthy server, show its URL and ask the user to use it or enter a different URL. Do not select a server automatically. Treat the …

How to install
mdr add nanocoai/nanoclaw/add-mattermost@sha256:3c380236d9927460The line at the top of this page pins the label git:20261022.8a91aad, 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.
