README
guerrillamail-mcp
MCP server for the Guerrilla Mail temporary/disposable email API. Spin up throwaway inboxes, poll for mail, and read messages from any MCP client — Claude Desktop, Claude Code, Cursor, or any other.
Zero config. No API key. One command.
npx -y guerrillamail-mcp
Why
Need a throwaway email inside an AI workflow — signup testing, OTP capture, scratch inbox — without leaving the agent? This wires Guerrilla Mail's disposable inboxes straight into the Model Context Protocol so your agent can create an address, watch for mail, and read it, all on its own.
Install & usage
Run directly with npx — no install needed:
npx -y guerrillamail-mcp
Claude Desktop
Add to your claude_desktop_config.json:
{
"mcpServers": {
"guerrillamail": {
"command": "npx",
"args": ["-y", "guerrillamail-mcp"]
}
}
}
Claude Code CLI
claude mcp add guerrillamail -- npx -y guerrillamail-mcp
