Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http cooper-email-mcp https://cooperemail.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add cooper-email-mcp --url https://cooperemail.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable cooper-email-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "cooper-email-mcp": {
      "url": "https://cooperemail.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.
Cline configuration
{
  "mcpServers": {
    "cooper-email-mcp": {
      "type": "streamableHttp",
      "url": "https://cooperemail.com/mcp",
      "disabled": false
    }

      "url": "https://cooperemail.com/mcp"
