Cursor

Cursor supports MCP servers via its settings. OpaqueVault works identically to the Claude Code integration.

---

Setup

In Cursor settings → MCP → Add server:

{
  "opaquevault": {
    "command": "ov",
    "args": ["mcp", "serve"]
  }
}

Or edit ~/.cursor/mcp.json directly:

{
  "mcpServers": {
    "opaquevault": {
      "command": "ov",
      "args": ["mcp", "serve"]
    }
  }
}

Restart Cursor. OpaqueVault’s 7 tools will be available to the AI.

Usage

Identical to Claude Code. Ask Cursor’s AI to run commands that need credentials — it will call vault_run automatically.

The interceptor runs regardless of which MCP client you use — it’s in ov mcp serve, not in the client.
