OpenCode Bridge 集成指南：CLI、数据库与MCP桥接实现AI助手通信

🇺🇸English

Overview

OpenWork communicates with OpenCode via three mechanisms:

1. CLI invocation : Spawn opencode with prompts and get JSON responses.
2. Database access : Read OpenCode's SQLite database for sessions and messages.
3. MCP bridge : Real-time bidirectional communication for streaming and permissions.

CLI Invocation

Non-interactive mode

opencode -p "your prompt" -f json -q

Returns JSON with the response content.

Flags

Example response

{
  "content": "Here is the result...",
  "session_id": "abc123"
}

Database Access

Location

~/.opencode/opencode.db

Or project-local:

.opencode/opencode.db

Schema (key tables)

sessions

CREATE TABLE sessions (
  id TEXT PRIMARY KEY,
  parent_session_id TEXT,
  title TEXT,
  message_count INTEGER,
  prompt_tokens INTEGER,
  completion_tokens INTEGER,
  summary_message_id TEXT,
  cost REAL,
  created_at INTEGER,
  updated_at INTEGER
);

messages

CREATE TABLE messages (
  id TEXT PRIMARY KEY,
  session_id TEXT,
  role TEXT,  -- 'user', 'assistant', 'tool'
  parts TEXT, -- JSON array of content parts
  model TEXT,
  created_at INTEGER,
  updated_at INTEGER
);

Querying from Rust (Tauri)

use tauri_plugin_sql::{Migration, MigrationKind};

#[tauri::command]
async fn list_sessions(db: tauri::State<'_, Database>) -> Result<Vec<Session>, String> {
    let sessions = sqlx::query_as::<_, Session>(
        "SELECT * FROM sessions ORDER BY updated_at DESC"
    )
    .fetch_all(&db.pool)
    .await
    .map_err(|e| e.to_string())?;
    
    Ok(sessions)
}

Querying from SolidJS

import Database from "@tauri-apps/plugin-sql";

const db = await Database.load("sqlite:~/.opencode/opencode.db");
const sessions = await db.select<Session[]>(
  "SELECT * FROM sessions ORDER BY updated_at DESC"
);

MCP Bridge (Advanced)

OpenWork can register as an MCP server that OpenCode connects to.

Configuration (opencode.json)

{
  "mcpServers": {
    "openwork": {
      "type": "stdio",
      "command": "openwork-mcp-bridge"
    }
  }
}

Use cases

• Real-time permission prompts surfaced in OpenWork UI.
• Streaming progress updates.
• Custom tools exposed from OpenWork (e.g., native file picker).

Message Content Parts

Messages contain a parts JSON array with different content types:

TextContent

{ "type": "text", "text": "Hello world" }

ToolCall

{
  "type": "tool_call",
  "id": "call_123",
  "name": "bash",
  "input": "{\"command\": \"ls\"}"
}

ToolResult

{
  "type": "tool_result",
  "tool_call_id": "call_123",
  "content": "file1.txt\nfile2.txt",
  "is_error": false
}

Finish

{
  "type": "finish",
  "reason": "end_turn",
  "time": 1704067200
}

Common Gotchas

• Database is SQLite; use read-only access to avoid conflicts with running OpenCode.
• Message parts are JSON-encoded strings; parse them in the UI.
• Session IDs are UUIDs; tool call IDs are also UUIDs.
• Cost is in USD; tokens are raw counts.

First-Time Setup

Verify OpenCode is installed

which opencode
opencode --version

Verify database exists

ls ~/.opencode/opencode.db

Test CLI invocation

opencode -p "Hello" -f json -q
