Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
Remote servers are capped at 8.0 because source code is not available for review. The score reflects endpoint verification only.
Permissions Required
This plugin requests these system permissions. Most are normal for its category.
How to Connect
Remote Plugin
No local installation needed. Your AI client connects to the remote endpoint directly.
Add this to your MCP configuration to connect:

OpenMail MCP
Hosted Streamable HTTP MCP at https://mcp.openmail.sh/mcp. Gmail for agents: one inbox, read mail that wants a reply, reply in-thread.
There is no local stdio catalog — stdio-only clients should use mcp-remote.
Connect
Claude (OAuth): paste https://mcp.openmail.sh/mcp
Cursor (OAuth): Add to Cursor, or add the URL below without headers. This repo is also a Cursor Marketplace plugin (.cursor-plugin/plugin.json + mcp.json).
Claude Code: claude mcp add --transport http openmail https://mcp.openmail.sh/mcp, or install as a plugin (.claude-plugin/plugin.json).
VS Code / any registry client: listed in the MCP Registry as sh.openmail/openmail.
Cursor or headless agents (API key):
{
"mcpServers": {
"openmail": {
"url": "https://mcp.openmail.sh/mcp",
"headers": { "Authorization": "Bearer om_YOUR_KEY" }
}
}
}
Prefer an inbox-scoped key. Read-only: /mcp/readonly. One inbox: /mcp/inbox/{id}.
Keys and transcripts: over OAuth (Claude, Cursor sign-in) setup_agent_email and mint_inbox_key never return a token — the session is already authenticated, and anything returned lands in the chat. They point to the console, which shows a new key once in the browser. Over an API key (headless agent) the token is returned in the tool result; move it to the agent's env.
stdio-only clients: npx -y mcp-remote https://mcp.openmail.sh/mcp
