Remote URL or a command on your machine? How the two installs differ

Run on PlugMCP

Host a copy with our keys and logs.

A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.

Read channels and posts, find users, send messages and files on any Synology Chat server.

synology-chat-mcp

MCP server for Synology Chat. Works with any self-hosted Synology Chat instance: list channels, read recent posts, find users, send messages and upload files from any MCP client (Claude Desktop, Claude Code, Hermes, ...).

It logs in as a normal DSM user through the Synology Web API, so it sees exactly what that user sees in Chat (channels and DMs), no bot or webhook setup needed.

Tools

ToolWhat it does
list_channels()Joined channels and DMs (id, name, type, members, unread)
find_user(name_query)Find users by partial username
get_recent_posts(channel_id, limit=20)Most recent messages/files in a channel or DM
dm_channel_for_user(user_id)1:1 DM channel id for a user, or null if none exists yet
send_message(channel_id, message)Post a text message
send_file(channel_id, file_path, message="")Upload a local file, optionally followed by a message

Configuration

All config comes from environment variables, set them in your MCP client config:

VariableRequiredExample
SYNOLOGY_CHAT_URLyeshttps://chat.example.com, https://nas.local:5001, http://192.168.1.10:5000
SYNOLOGY_CHAT_USERyesDSM username
SYNOLOGY_CHAT_PASSyesDSM password
SYNOLOGY_CHAT_VERIFY_SSLnofalse for self-signed certificates (default true)

A URL without scheme means https, without port it uses 443 (https) or 80 (http).

Install

Needs uv. No clone required, uvx runs it straight from GitHub.

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "synology-chat": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/Louis-Lastella/synology-chat-mcp", "synology-chat-mcp"],
      "env": {
        "SYNOLOGY_CHAT_URL": "https://chat.example.com",
        "SYNOLOGY_CHAT_USER": "your-username",
        "SYNOLOGY_CHAT_PASS": "your-password"
      }
    }
  }
}

Claude Code:

claude mcp add synology-chat \
  -e SYNOLOGY_CHAT_URL=https://chat.example.com \
  -e SYNOLOGY_CHAT_USER=your-username \
  -e SYNOLOGY_CHAT_PASS=your-password \
  -- uvx --from git+https://github.com/Louis-Lastella/synology-chat-mcp synology-chat-mcp

Hermes (~/.hermes/config.yaml):

mcp_servers:
  synology-chat:
    command: uvx
    args: [--from, git+https://github.com/Louis-Lastella/synology-chat-mcp, synology-chat-mcp]
    env:
      SYNOLOGY_CHAT_URL: https://chat.example.com
      SYNOLOGY_CHAT_USER: your-username
      SYNOLOGY_CHAT_PASS: your-password

From a local clone instead: git clone, uv sync, then use uv with args --directory /path/to/synology-chat-mcp run synology-chat-mcp.

Docker (no uv needed), image ghcr.io/louis-lastella/synology-chat-mcp:

{
  "mcpServers": {
    "synology-chat": {
      "command": "docker",
      "args": ["run", "-i", "--rm",
               "-e", "SYNOLOGY_CHAT_URL", "-e", "SYNOLOGY_CHAT_USER", "-e", "SYNOLOGY_CHAT_PASS",
               "ghcr.io/louis-lastella/synology-chat-mcp"],
      "env": {
        "SYNOLOGY_CHAT_URL": "https://chat.example.com",
        "SYNOLOGY_CHAT_USER": "your-username",
        "SYNOLOGY_CHAT_PASS": "your-password"
      }
    }
  }
}

Also listed in the official MCP Registry as io.github.Louis-Lastella/synology-chat-mcp.

Notes

  • Accounts with 2-factor authentication are not supported (the Web API wants a fresh OTP per login). Use an account without 2FA.
  • DMs show up with type anonymous, that is Synology's name for 1:1 conversations.
  • find_user only matches the username, not display names.
  • Downloading attachments is not a tool yet. The session is available via synology_chat_mcp._client().session; call GET /webapi/entry.cgi?api=SYNO.Chat.Post.File&method=get&version=2&post_id=<id>&_sid=<sid> with the header X-SYNO-TOKEN: <session.syno_token>.

Development

uv sync
uv run python tests/test_parse_url.py
