Set up

Add Superhuman Mail to Windsurf in four steps

Admins approve the server once. Everyone in Windsurf 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 Windsurf to Runlayer

    Users add the Runlayer Plugin to Windsurf by following Runlayer’s setup guide. Windsurf 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 Windsurf

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

Tools

33 Superhuman Mail tools in Windsurf

Runlayer policy decides which of these Windsurf 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 Windsurf

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

  • Gateway policy (available)

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

  • Audit trail (available)

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

  • Client hooks (available)

    Capture supported prompts, reasoning, local and MCP tool calls, responses, and scanner decisions in real time.

  • Stop a call before it runs (available)

    Runlayer can deny a tool call before Windsurf runs it.

  • Block output after it runs (not available)

    Windsurf ignores Runlayer after a tool runs, so Runlayer cannot block its output. The gateway still applies policy to the call.

  • Redact output in place (not available)

    Windsurf has no way to receive replacement output, so Runlayer cannot mask it. The gateway still applies policy to the call.

In Windsurf

  • Enforcement needs Windsurf 1.12.31 or newer.
  • When Runlayer denies a call, Windsurf shows the reason to the user; Runlayer cannot adjust the call’s inputs.
