Cursor Memory Integration

Give Cursor long-term memory across projects and sessions. After installation, OpenViking Hooks inject relevant context at session start and before each request, then capture new conversation turns after the response. MCP is available for explicit memory search, reading, and management.

Install

Prerequisites: macOS or Linux, Node.js 18+, and preferably the latest stable Cursor release. 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.

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

If GitHub is unavailable, use the TOS mirror:

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

Quit Cursor completely and restart it after installation.

What gets installed

• Lifecycle Hooks for profile loading, prompt recall, conversation capture, session commit, and viking:// URI protection.
• The OpenViking MCP server with tools such as search, recall, read, and remember.
• An always-on Rule and memory Skill that tell the Agent how to use injected context and memory tools.

Verify

1. Restart Cursor and create a new Agent session.
2. Open Cursor Settings → Hooks and confirm that the OpenViking lifecycle Hooks execute cursor-hook.mjs and its URI protection Hooks execute uri-guard.mjs.
3. Check that the beforeSubmitPrompt output contains additional_context. This confirms that recall reaches the Agent without requiring an MCP call first.
4. Open Cursor Settings → Tools & MCPs and confirm that openviking is connected.
5. Tell Cursor a temporary preference, wait for the response to finish, then create a new session and ask for that preference to verify capture and cross-session recall.

How it works

• sessionStart loads your profile and the current project's memory index.
• beforeSubmitPrompt recalls context for the current request and injects it through additional_context.
• beforeReadFile and beforeShellExecution redirect accidental local access to viking:// paths back to OpenViking MCP tools.
• stop incrementally captures new user and assistant messages.
• preCompact and sessionEnd commit pending messages for memory extraction.

Project identity uses Cursor's workspace_roots, keeping workspace peers separate. Hooks and MCP share credentials from ~/.openviking/ovcli.conf.

Upgrade and uninstall

Re-run the install command from the same distribution channel to upgrade. Use the same channel for uninstall:

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

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

Uninstall removes only OpenViking-managed Cursor Hooks, MCP, Rule, Skill, and runtime files. Other configuration is preserved.
