OpenCode

Configure OpenCode, the open source AI coding assistant, to use agentgateway as an MCP server.

Before you begin

1. Install and run agentgateway.
2. Confirm agentgateway is up by opening the agentgateway UI.
3. Use the same MCP endpoint and port that your local config exposes. Common examples include:
   • http://localhost:15000/mcp/sse
   • http://localhost:15000/mcp/http
   • If you run agentgateway on a different host or port, replace localhost:15000 in the examples accordingly.

Configuration

Add agentgateway to your OpenCode configuration file ~/.opencode/config.json:

{
  "mcp": {
    "servers": {
      "agentgateway": {
        "type": "sse",
        "url": "http://localhost:15000/mcp/sse"
      }
    }
  }
}

Project-Level Configuration

For project-specific configuration, create .opencode/config.json in your project root:

{
  "mcp": {
    "servers": {
      "agentgateway": {
        "type": "sse",
        "url": "http://localhost:15000/mcp/sse"
      }
    }
  }
}

Using Streamable HTTP

For improved performance, use the streamable HTTP transport:

{
  "mcp": {
    "servers": {
      "agentgateway": {
        "type": "http",
        "url": "http://localhost:15000/mcp/http"
      }
    }
  }
}

Authentication

Include authentication if required:

{
  "mcp": {
    "servers": {
      "agentgateway": {
        "type": "sse",
        "url": "http://localhost:15000/mcp/sse",
        "headers": {
          "Authorization": "Bearer your-token-here"
        }
      }
    }
  }
}
