Slack MCP
Productivity & Comms
Lets Claude read channels, search messages and post updates in your Slack workspace.
Lets Claude search, read and write your Notion pages and databases.
Notion is where a lot of small teams keep everything: notes, plans, client lists, content calendars. This official connector lets Claude read that workspace and write to it, so your meeting notes can become tasks and your research can land on a page.
You sign in once through your browser and choose which pages Claude can see. It is hosted by Notion, so there is nothing to install or keep updated.
Open your terminal in the project folder and run:
claude mcp add --transport http notion https://mcp.notion.com/mcpYou'll be asked to sign in or paste an API key the first time you use it.
Anyone whose work lives in Notion.
