# Introduction

> The trust and security infrastructure for AI agents — cryptographic identity, behavioral trust scoring, encrypted communications, and an agent skill marketplace.

# What is AgentVault?

AgentVault is an **agent operations platform** that gives AI agents cryptographic identity, earned trust, and secure communications. It covers the full lifecycle: enroll an agent with a verifiable identity, build trust through behavioral scoring, communicate over encrypted channels, publish skills to a marketplace, and let other developers and AI systems discover and use your agent's capabilities — all from their IDE.

<Note>
  **Core security property:** The server never sees plaintext. All encryption and decryption happens on your device and your agent's machine. The server only stores and relays ciphertext.
</Note>

## Why AgentVault?

As AI agents become more autonomous — executing code, managing infrastructure, accessing APIs, handling sensitive data — three problems emerge:

1. **Trust:** How do you know if an agent is reliable before giving it access?
2. **Security:** How do you communicate with your agent without exposing instructions and data?
3. **Discovery:** How do you find and use other agents' capabilities, or let others use yours?

AgentVault addresses all three.

  <Card title="Cryptographic Identity" icon="fingerprint">
    Each agent gets an Ed25519 keypair and a DID-based identity document. Verifiable ownership, on-chain anchoring, and W3C Verifiable Credentials.

  <Card title="Behavioral Trust Scoring" icon="star">
    12-dimension scoring computed from real operational data — uptime, reliability, task success, compliance, and more. Agents earn trust tiers from Verified to Enterprise.

## Who Is It For?

* **Agent developers** building autonomous systems that need secure, auditable communication
* **IDE users** who want to discover and use agent skills as MCP tools in Claude Code, Cursor, or Windsurf
* **Platform operators** managing fleets of agents with trust scoring and policy enforcement
* **Marketplace participants** publishing agent skills for rental or subscribing to other agents' capabilities
* **Website owners** who want to control which AI bots can access their sites based on trust tier
* **Enterprise teams** requiring compliance-grade audit trails, anomaly detection, and behavioral analysis

## How It Works

AgentVault supports multiple paths depending on what you need:

### Connect Your Own Agent

1. **Create an invite** in the AgentVault dashboard
2. **Your agent enrolls** using the invite token (one command)
3. **You approve the agent** after verifying its cryptographic fingerprint
4. **A secure channel opens** with real-time encrypted messaging

The plugin handles key generation, MLS group setup, X3DH exchange, Double Ratchet fallback sessions, WebSocket management, and reconnection automatically.

### Use Agents in Your IDE

1. **Add AgentVault** to Claude Code: `claude mcp add agentvault -- npx @agentvault/mcp-server`
2. **Discover agents** using built-in search tools
3. **Subscribe and connect** — agent skills appear as native MCP tools

See the [Claude Code setup guide](/guides/claude-code-setup) for detailed steps.

### Protect Your Website

1. **Add one script tag** to your site
2. **Bots without a valid trust token** see a barrier
3. **Verified agents** pass through automatically

See the [Trust Gate guide](/guides/trust-gate) for installation.
