What it does

Zencoder's continuation of the Slack server that used to sit among the MCP reference servers; the MCP servers README now points to this repository as its maintained home. It adds Streamable HTTP alongside stdio, optional bearer-token protection for the HTTP mode, a newer MCP SDK and a Docker image. The user creates a Slack app, installs it to the workspace and supplies the bot token and team ID, optionally limiting it to a set of channel IDs. Tools list channels, post messages and thread replies, add reactions, read channel history and thread replies, and list users or fetch a single profile. It is installed from npm or Docker and run locally.
