Setup by agent
/plugin install slack@claude-plugins-officialWe haven't verified a OpenAI Codex setup for Slack yet. If the vendor documents an MCP server, the MCP config generator gives you the right ~/.codex/config.toml (user) format. Config locations: Codex setup.
We haven't verified a Cursor setup for Slack yet. If the vendor documents an MCP server, the MCP config generator gives you the right .cursor/mcp.json (project) format. Config locations: Cursor setup.
We haven't verified a GitHub Copilot setup for Slack yet. If the vendor documents an MCP server, the MCP config generator gives you the right .vscode/mcp.json (workspace) format. Config locations: Copilot setup.
We haven't verified a Google Antigravity setup for Slack yet. If the vendor documents an MCP server, the MCP config generator gives you the right ~/.gemini/config/mcp_config.json (global) format. Config locations: Antigravity setup.
