Perplexity

Automate credential generation in Cursor

Generate dynamic credentials on the fly while coding. Use `generate_aws_creds` or `generate_database_creds` to get temporary access that expires automatically. Your code gets real, working tokens that you can test immediately. It removes the need for hardcoded static secrets in your local environment.

Encrypt data inside Cursor

Use the Transit engine to handle sensitive fields in your application code. The AI can call `encrypt_transit` to secure data before it ever hits your database. It makes implementing Encryption as a Service trivial. You just define the key and let the tool handle the heavy lifting.

Configure auth methods from Cursor

Set up your environment by running `configure_kubernetes_auth` or `configure_aws_root` directly from your editor. You can define your security posture without switching windows. Keep your infrastructure as code. Use these tools to update policies via `create_acl_policy` as your application requirements evolve.

Setup guide

Set up HashiCorp Vault MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the HashiCorp Vault MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent HashiCorp Vault transactions." If the MCP tools are loaded correctly, Cursor will call the HashiCorp Vault tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "hashicorp-vault-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }

Common questions about HashiCorp Vault MCP in Cursor

Create a .cursor/mcp.json file in your project root. Define the server there, and the AI will gain access to your tools for that specific codebase.

Yes. When you enable agent mode, the AI can call tools like `read_kv_secret` to fetch live config while it writes your implementation.

The tools only return data to your local session. Your secrets stay within the Vault cluster and are not shared with the AI model providers.

Yes. You can trigger `rotate_transit_key` through the chat interface. It updates the versioning on your server without manual intervention.

The server only touches your KV secrets when requested. The AI ignores your actual secret values during global indexing because they are fetched dynamically at runtime.
