DemiPass

Secrets management SDK for AI agents. Keep credentials out of context windows.

DemiPass is a client SDK for the Dustforge identity platform. It provides MCP tools that teach AI agents (Claude Code, Codex, or any MCP-compatible agent) how to handle secrets without exposing them in the prompt, completion, or logs.

How it works

1. You store a credential → DemiPass encrypts it server-side
2. Your agent requests a 30-second use-token via ref code
3. DemiPass injects the secret server-side (SSH, HTTP header, etc.)
4. The agent gets the result back — never the secret itself

Install

npm install demipass

MCP Setup

Add to your .mcp.json:

{  "mcpServers": {    "demipass": {      "command": "node",      "args": ["node_modules/demipass/mcp-server.js"],      "env": {        "DEMIPASS_URL": "https://api.dustforge.com",        "DEMIPASS_TOKEN": "your-bearer-token"      }    },    "buoy": {      "command": "node",      "args": ["node_modules/demipass/buoy-mcp.js"],      "env": {        "BUOY_URL": "https://api.dustforge.com",        "BUOY_TOKEN": "your-bearer-token"      }    }  }}

DemiPass (secrets)

Buoy (temporal anchoring)

SDK Usage

const demipass = require('demipass');
demipass.configure({  baseUrl: 'https://api.dustforge.com',  bearerToken: 'your-token',});
// Store a secretawait demipass.store({ name: 'my-api-key', value: 'sk-...', type: 'api_key' });
// SSH via ref code (password never in your code)await demipass.ssh({ ref: 'DP-PWD-myserver-7f3a9c1e', target_host: '1.2.3.4', command: 'uptime' });
// Search secretsawait demipass.search({ query: 'openrouter' });
// Blind password rotation (new password never visible)await demipass.rotateBlind({ ref: 'DP-PWD-old-ref', target_host: '1.2.3.4', reason: 'exposed' });

Architecture

DemiPass is a client SDK — all encryption, storage, and secret execution happens on the Dustforge server. This package provides:

• MCP tool definitions with behavioral descriptions that teach agents the protocol
• SDK functions that wrap the Dustforge API
• Self-healing contexts — if a secret has no approved context, the SDK auto-creates one
• Buoy MCP tools for temporal anchoring and audit trails

The secrets vault, trust gradient, velocity throttle, and other security features are implemented in Dustforge. See dustforge.com for the platform documentation.

Ref Codes

Every stored secret gets a routed reference code:

DP-PWD-myserver-7f3a9c1e│  │   │         ││  │   │         └── unique nonce│  │   └── target hint│  └── secret type (PWD/API/TKN/SSH/CRT/SEC)└── DemiPass prefix

Share ref codes freely — they're routing addresses, not secrets.
