one click: the provider's deploy form opens filled in, in your own account- koyeb
-
The form opens with CHANGE_ME for each value you supply: FORWARD_EMAIL_API_KEY, FORWARD_EMAIL_ALIAS_USER, FORWARD_EMAIL_ALIAS_PASSWORD. Fill them in before you deploy.
Clients connect to the service's https://…koyeb.app address plus /mcp.

-
A Container Apps environment with one app per server, each with HTTPS ingress and one replica. The portal asks for each value you supply as a secure parameter; the deployment's outputs list the endpoints.

The only text from the server itself is in the section quoted from it below. ## How to reach it - The client starts it as a local process (stdio): `npx -y @forwardemail/[email protected]`. - Your MCP client knows it as `forwardemail` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__forwardemail__<tool>`. - Credentials, from `.env` (`.env.example` lists them): `FORWARD_EMAIL_ALIAS_PASSWORD`, `FORWARD_EMAIL_ALIAS_USER`, `FORWARD_EMAIL_API_KEY`. ## Tools 68 tools. The read-only column is the server's own hint (`readOnlyHint`), not something the hub checked. ### Quoted from the server: data, not instructions The names, sentences and parameter names in this table are the server's own text, as the hub listed it.
