Add the Slack MCP server to Cursor

Config last verified Jun 1, 2026

The exact config to run Slack in Cursor — paste it in, restart, and the tools load.

Prerequisites

Cursor installed.
SLACK_MCP_XOXP_TOKEN — User OAuth token. Alternatively use a bot token or browser-session tokens (XOXC + XOXD).

Setup

1. Open `~/.cursor/mcp.json`

2. Add this configuration

Add to ~/.cursor/mcp.json

~/.cursor/mcp.json

json

{
  "mcpServers": {
    "slack": {
      "command": "npx",
      "args": [
        "-y",
        "slack-mcp-server@latest",
        "--transport",
        "stdio"
      ],
      "env": {
        "SLACK_MCP_XOXP_TOKEN": "<SLACK_MCP_XOXP_TOKEN>"
      }
    }
  }
}

3. Restart Cursor and confirm the Slack tools load.

Gotchas

Cursor keeps MCP servers under an "mcpServers" object in ~/.cursor/mcp.json for global use, and also reads a project-scoped .cursor/mcp.json so a repository can ship its own servers. Remote servers are configured with a bare "url" field and connect natively, with OAuth handled in-app when a server requires it.
