Sharing it with your team?

Add `--scope project` to write it to .mcp.json in the repository root, which you can commit (with the secrets left as environment variables).

Use it in a session

Ask Claude to use the tools this server exposes. It discovers them automatically.

Open your MCP config

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

Add this server

{
  "mcpServers": {
    "slack": {
      "command": "uvx",
      "args": [
        "mcparmory-slack"
      ]
    }
  }
}

Restart Claude Desktop

The tools appear under the 🔌 menu once the app reloads.

Create / edit .cursor/mcp.json in your project

{
  "mcpServers": {
    "slack": {
      "command": "uvx",
      "args": [
        "mcparmory-slack"
      ]
    }
  }
}

Enable it

Cursor Settings → MCP → toggle the server on. Tools become available to the Composer/Agent.

Add to ~/.codex/config.toml

[mcp_servers.slack]
command = "uvx"
args = ["mcparmory-slack"]

Run Codex

Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.

Edit ~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "slack": {
      "command": "uvx",
      "args": [
        "mcparmory-slack"
      ]
    }
  }
}

Reload

Windsurf → Cascade → refresh MCP servers. Cascade can now call the tools.

Open Cline → MCP Servers → Configure

Adds to cline_mcp_settings.json.

Add the server

{
  "mcpServers": {
    "slack": {
      "command": "uvx",
      "args": [
        "mcparmory-slack"
      ]
    }
  }
}

Create .vscode/mcp.json

{
  "servers": {
    "slack": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "mcparmory-slack"
      ]
    }
  }
}

Start it

VS Code shows a ▶ Start action above the server entry. Agent mode (Copilot Chat) can then use the tools.
