TRAE and TRAE CN Memory Integration

Give TRAE and TRAE CN long-term memory across projects and sessions. OpenViking Hooks automatically load relevant context, capture each conversation turn, and commit it for memory extraction. MCP remains available for explicit memory search, reading, and management.

Install

Prerequisites: macOS or Linux, Node.js 18+, and a TRAE/TRAE CN release that supports the SessionStart, UserPromptSubmit, PreToolUse, and Stop Hooks. The installer guides you through the OpenViking connection settings.

When prompted for the connection, Volcengine Cloud users should select Volcengine OpenViking Cloud and enter their API key. Select Self-hosted / local only when an OpenViking server is running locally.

# TRAE
bash <(curl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/memory-plugin-shared/install.sh) \
  --harness trae

# TRAE CN
bash <(curl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/memory-plugin-shared/install.sh) \
  --harness trae-cn

# Both
bash <(curl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/memory-plugin-shared/install.sh) \
  --harness trae,trae-cn

If GitHub is unavailable, use the TOS mirror:

bash <(curl -fsSL https://ovrelease.tos-cn-beijing.volces.com/memory-plugin-shared/install.sh) \
  --harness trae,trae-cn --dist tos

Quit and restart the corresponding client after installation.

What gets installed

• SessionStart loads your profile and current project memory.
• UserPromptSubmit recalls and injects context for the current request.
• PreToolUse redirects accidental local access to viking:// paths back to OpenViking MCP tools.
• Stop captures and immediately commits the completed turn, including short sessions.
• The OpenViking MCP server provides explicit tools such as search, recall, read, and remember.

Verify

1. Restart TRAE or TRAE CN and create a new Agent session.
2. Confirm that openviking is connected in the client's MCP settings.
3. Ask about an existing project or preference and confirm that the answer uses stored memory.
4. Tell the Agent a temporary preference, wait for the response to finish, then create a new session and ask for it again to verify capture, commit, and cross-session recall.

For Hook diagnostics, start the client with OPENVIKING_DEBUG=1 and inspect:

• TRAE: ~/.openviking/logs/trae-hooks.log
• TRAE CN: ~/.openviking/logs/trae-cn-hooks.log

Upgrade and uninstall

Re-run the corresponding install command to upgrade. Use the original distribution channel for uninstall:

# GitHub, TRAE CN example
bash <(curl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/memory-plugin-shared/install.sh) \
  --harness trae-cn --uninstall --yes

# TOS, TRAE CN example
bash <(curl -fsSL https://ovrelease.tos-cn-beijing.volces.com/memory-plugin-shared/install.sh) \
  --harness trae-cn --uninstall --yes

Replace trae-cn with trae for TRAE. Uninstall removes only OpenViking-managed configuration and runtime files.
