Transport: Streamable HTTP
Runtime: Web executable

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to waystation.ai, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote WayStation endpoint that lets an assistant send messages, reach channels and manage files in a Slack workspace.

What you can do: Send messages and post into Slack channels
Access channels and workspace content
Manage files in the Slack workspace
Reach Slack through a shared WayStation hub that also fronts other productivity apps
When to use it: Use it when you want an assistant to read or act inside a Slack workspace from an MCP host such as Claude, Cursor or Cline, without running a local server.
Requirements: A remote MCP endpoint at waystation.ai; the README points to the per-user URL at waystation.ai/mcp with a unique ID from the WayStation dashboard. A WayStation account and a Slack connection made through its dashboard, generally via OAuth2, are needed. No packages or environment variables are declared.

Before you install

The endpoint is a shared hub that also connects other apps such as Notion, Jira and Google Drive, so the assistant may reach more than Slack. The README describes preauthenticated per-user URLs, which act as credentials and should be kept private. Sending messages and managing files changes workspace data.

Installation

In SourceWeft

Open Slack in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.waystation%2Fslack/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
