Set up

Add Hex to OpenCode in four steps

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

  1. 1

    Approve Hex in Runlayer

    Add Hex 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 Hex’s 18 tools through the Runlayer Plugin’s search and execute tools instead of listing each one.

  3. 3

    Sign in to Hex

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

  4. 4

    Use Hex from OpenCode

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

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 Hex 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.
