Set up

Add Superhuman Mail to OpenCode in four steps

Admins approve the server once. Everyone in OpenCode then gets it through the same governed connection.

  1. 1

    Approve Superhuman Mail in Runlayer

    Add Superhuman Mail from the catalog and choose who can use it and which of its tools are allowed.

  2. 2

    Connect OpenCode to Runlayer

    Users add the Runlayer Plugin to OpenCode by hand using Runlayer’s generic MCP steps. OpenCode reaches Superhuman Mail’s 33 tools through the Runlayer Plugin’s search and execute tools instead of listing each one.

  3. 3

    Sign in to Superhuman Mail

    Sign in the way Superhuman Mail requires. Runlayer holds the credentials so they stay out of the client’s configuration.

  4. 4

    Use Superhuman Mail from OpenCode

    Superhuman Mail’s approved tools appear in OpenCode. Every call is checked against policy and recorded.

Tools

33 Superhuman Mail tools in OpenCode

Runlayer policy decides which of these OpenCode users can call.

  • Add account

    Start linking an additional Superhuman Mail account to this session so it can be acted on alongside the current account.

  • Create or update draft

    Compose an email on behalf of the user.

  • Create or update event

    Create a new calendar event or edit an existing one.

  • Create or update reminder

    Create or reschedule a reminder on a Superhuman Mail thread.

  • Create or update snippet

    Save a reusable Superhuman Mail snippet (an email template).

  • Discard draft

    Discard a user-owned Superhuman Mail draft by draft_id so it disappears from the user's Drafts list.

  • Discard reminder

    Discard (cancel) a reminder on a Superhuman Mail thread so it no longer brings the thread back to the top of the inbox.

  • Discard snippet

    Remove a saved Superhuman Mail snippet, identified by the id from list_snippets.

Control

What Runlayer can see and stop in OpenCode

Some controls apply to every client at the gateway. Others depend on what OpenCode exposes to Runlayer.

  • Gateway policy (available)

    Every Superhuman Mail call from OpenCode passes through Runlayer, where your policies can allow, alert, mask, or block it.

  • Audit trail (available)

    Each call is recorded with the user, OpenCode as the client, the tool, and the policy and scanner decisions.

  • Native enforcement adapter (not available)

    Runlayer has no device-side adapter for OpenCode yet, so control happens at the gateway.
