Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "secure-vault": {
      "command": "npx",
      "args": [
        "-y",
        "secure-vault-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add secure-vault -- npx -y secure-vault-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "secure-vault": {
      "command": "npx",
      "args": [
        "-y",
        "secure-vault-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "secure-vault": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "secure-vault-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Secure Vault safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

secure-vault-mcp

MCP server for agent-native secrets management. 24,008 secrets have been found in MCP config files on public GitHub. This server solves that.

Agents need secrets to call APIs, but they shouldn't see raw values. secure-vault-mcp stores secrets encrypted with AES-256-GCM, issues short-lived scoped tokens, and injects secrets into requests server-side so the agent never handles plaintext credentials.

Install

npx secure-vault-mcp

Claude Desktop

Add to claude_desktop_config.json:

"mcpServers": { "secure-vault": { "command": "npx", "args": ["secure-vault-mcp"] } } }

From source

git clone https://github.com/mdfifty50-boop/secure-vault-mcp.git

cd secure-vault-mcp npm install node src/index.js

Tools

store_secret

Store an encrypted secret with optional rotation policy.

Param	Type	Default	Description
`name`	string	required	Secret name (e.g. "openai_api_key")
`value`	string	required	Secret value — encrypted immediately
`service`	string	`"default"`	Service this secret belongs to
`rotation_policy`	string	`"none"`	`"none"`, `"daily"`, `"weekly"`, `"monthly"`

get_agent_token

Issue a short-lived, scoped token. The agent receives an opaque token ID, never the raw secret.

Param	Type	Default	Description
`agent_id`	string	required	Requesting agent identifier
`service`	string	required	Service to get a token for
`scope`	string	`"read"`	`"read"`, `"write"`, `"admin"`
`ttl_seconds`	number	300	Token TTL (10s to 86400s)

rotate_secrets

Rotate all secrets for a service. Old tokens are invalidated.

Param	Type	Description
`service`	string	Service whose secrets to rotate
`new_value`	string	New secret value

audit_secret_access

View who accessed what secrets over a time range.

Param	Type	Default	Description
`time_range`	string	`"24h"`	`"1h"`, `"6h"`, `"24h"`, `"7d"`, `"all"`
`agent_id`	string	optional	Filter by agent
`secret_name`	string	optional	Filter by secret

scan_config_for_leaks

Scan config text for exposed secrets. Detects AWS keys, GitHub tokens, OpenAI/Anthropic keys, Slack tokens, Stripe keys, private key blocks, bearer tokens, and generic credentials using 12 regex patterns.

Param	Type	Default	Description
`config_text`	string	required	Config content to scan
`source_label`	string	`"unknown"`	Label for audit trail

inject_secret_to_request

Return a request with the secret injected server-side. The agent provides a template with {{SECRET}} placeholder and a valid token ID.

Param	Type	Description
`token_id`	string	Token from get_agent_token
`request_template`	string	Template with `{{SECRET}}` placeholder

Resources

URI	Description
`secure-vault://secrets`	All stored secret names with metadata (no raw values)

Usage Pattern

1. store_secret — store credentials at setup time

get_agent_token — agent requests a scoped, time-limited token
inject_secret_to_request — inject secret into API call template
rotate_secrets — rotate when needed, old tokens auto-invalidate
scan_config_for_leaks — check config files before committing
audit_secret_access — review access trail

Security Model

Secrets encrypted at rest with AES-256-GCM using a server-generated key
Agents receive opaque token IDs, never raw secret values
Tokens are scoped (read/write/admin) and time-limited (default 5 minutes)
Token rotation invalidates all outstanding tokens for the rotated secret
Full audit trail of every store, token issuance, and injection
In-memory storage — secrets exist only for the server session lifetime
