Connect Grain to OpenCode
Give OpenCode governed access to Grain’s 15 tools through Runlayer, with identity, policy, scanning, and audit on every call.
Set up
Add Grain to OpenCode in four steps
Admins approve the server once. Everyone in OpenCode then gets it through the same governed connection.
- 1
Approve Grain in Runlayer
Add Grain from the catalog and choose who can use it and which of its tools are allowed.
- 2
Connect OpenCode to Runlayer
Users add the Runlayer Plugin to OpenCode by hand using Runlayer’s generic MCP steps. OpenCode reaches Grain’s 15 tools through the Runlayer Plugin’s search and execute tools instead of listing each one.

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

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 Grain 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.
