Remote OpenCode MCP Server

A Model Context Protocol (MCP) server that enables remote access to OpenCode AI coding agent. This allows MCP-compatible clients (Claude Desktop, Cursor, etc.) to leverage OpenCode's capabilities.

Features

• Remote OpenCode Integration: Connect to OpenCode instances running anywhere
• MCP Protocol: Full MCP server implementation with SSE transport
• 4 Core Tools:
  • Create new sessions
  • Send prompts with automatic timeout handling
  • Check session status and history
  • List all sessions
• Configurable Timeout: Adjustable task timeout via environment variable
• Authentication Support: Optional password protection

Requirements

• Python 3.12+
• OpenCode running in serve mode

OpenCode Serve Mode

This MCP server requires OpenCode to be running in serve mode with API enabled:

opencode --serve

Or with custom port and password:

opencode --serve --port 4096 --password your_password

Make sure OPENCODE_URL and OPENCODE_SERVER_PASSWORD in your .env match the serve command.

Installation

From Source

git clone https://github.com/Dirichelet/remote-opencode-mcp.git
cd remote-opencode-mcp
uv sync

Using uv

uv add remote-opencode-mcp

Configuration

Create a .env file (copy from example.env):

cp example.env .env

Environment Variables

Variable	Description	Default
OPENCODE_URL	OpenCode server URL	http://127.0.0.1:4096
OPENCODE_SERVER_PASSWORD	Authentication password	(none)
MCP_PORT	MCP server port	14962
OPENCODE_TASK_TIMEOUT	Task wait timeout in seconds (0 for async)	60

Usage

Start the Server

python server.py

Or with uv:

uv run python server.py

Output:

=========================================
🚀 OpenCode MCP Server started
🎯 Target: http://127.0.0.1:4096
⏱️ Task timeout: 60 seconds
🔗 SSE URL:  http://127.0.0.1:14962/sse
=========================================

Input:

{
  "session_id": "ses_xxxx"
}

4. opencode_list_sessions

List all sessions.

MCP Client Integration

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "opencode": {
      "command": "uv",
      "args": ["--directory", "/path/to/remote-opencode-mcp", "run", "python", "server.py"]
    }
  }
}

Other MCP Clients

Connect to the SSE endpoint:

http://localhost:14962/sse

Workflow Example

User → MCP Client → remote-opencode-mcp → OpenCode Server
                              ↓
                      1. Create session
                      2. Send prompt
                      3. Wait for result
                      4. Return to client
