📝 Bug Description

engram --help instructs the user to add the following block to opencode.json:

{
  "mcp": {
    "engram": {
      "type": "stdio",
      "command": "engram",
      "args": ["mcp", "--tools=agent"]
    }
  }
}

This produces the following error @ opencode:

❯ opencode
Error: Configuration is invalid at ~/.config/opencode/opencode.json
↳ Invalid input mcp.engram

Using the following syntax seems to go through, opencode opens without complaining:

{
  "mcp": {
    "engram": {
      "type": "local",
      "command": ["engram", "mcp", "--tools=agent"],
      "enabled": true
    }
}

🔄 Steps to Reproduce

1. Configure engram mcp as instructed by engram --help in opencode.json:

{
  "mcp": {
    "engram": {
      "type": "stdio",
      "command": "engram",
      "args": ["mcp", "--tools=agent"]
    }
  }
}

2. Start opencode:

❯ opencode

You will see the following error:

Error: Configuration is invalid at ~/.config/opencode/opencode.json
↳ Invalid input mcp.engram

Note

❯ opencode --version
1.2.27
