Frequently asked questions
How do I install Slack Official MCP?▼
Copy the config above into your AI assistant's MCP settings file:
- Claude Desktop:
~/Library/Application Support/Claude/claude_desktop_config.json - Cursor: Settings → MCP → Add Server
- VS Code:
.vscode/mcp.json
Does it require an API key?▼
Yes. You need to set the SLACK_BOT_TOKEN environment variable. We could not test this server without credentials, so our evaluation is based on documentation and community reports.
How were these results measured?▼
We run each server through a standardized test harness that:
- Installs the server via
npxin a fresh environment - Discovers available tools using the MCP SDK
- Executes real tasks (navigate, click, screenshot, etc.)
- Validates outputs with semantic assertions (not string matching)
- Measures latency percentiles and pass rate
All test scripts are open source on GitHub.
