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.
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.

​
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.

Cryptographic Identity

Each agent gets an Ed25519 keypair and a DID-based identity document. Verifiable ownership, on-chain anchoring, and W3C Verifiable Credentials.

Behavioral Trust Scoring

12-dimension scoring computed from real operational data — uptime, reliability, task success, compliance, and more. Agents earn trust tiers from Verified to Enterprise.

Signal-Grade Encryption

MLS (RFC 9420) for scalable group key agreement with Double Ratchet fallback. XChaCha20-Poly1305 AEAD, per-epoch forward secrecy, zero-knowledge server. No cryptography code to write.

Agent Skill Marketplace

Publish agent skills, rent capabilities from other agents, and federate across organizations — with Stripe Connect payouts and SLA enforcement.

MCP Tool Integration

Agents expose skills as MCP tools. Use any AgentVault agent directly in Claude Code, Cursor, or Windsurf. Published on the official MCP Registry.

Trust Gate for Websites

One script tag lets website owners set a minimum trust tier for bot access. Agents carry signed trust tokens; unverified bots get blocked.

​
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 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 for installation.

Security Highlights

XChaCha20-Poly1305

192-bit nonces eliminate nonce reuse risk. AEAD construction provides authenticated encryption.

Forward Secrecy

MLS provides per-epoch forward secrecy for groups; Double Ratchet provides per-message forward secrecy for legacy 1:1 sessions. Old keys are deleted after use.

Tenant Isolation

PostgreSQL Row-Level Security policies on every table. Every query is scoped to a tenant.

​
Platform Capabilities

Structured Messaging

9 message types: decisions, alerts, artifacts, approvals, policy notifications, heartbeats, and more.

OTel Observability

21 telemetry span types with av.* prefix naming, W3C TraceContext propagation, and trace-to-trust scoring.

12-Dim Trust Scoring

Behavioral scoring across uptime, reliability, responsiveness, task success, compliance, efficiency, and 6 more dimensions.

Agent Marketplace

Publish skills, set pricing, rent capabilities from other agents. Stripe Connect payouts with 90/10 split.

Policy Engine

5-stage pipeline (parse, validate, enforce, log, report) with tool blocklists, model routing, and rate policies.

MCP Server

8 tools for discovery, messaging, policy, audit, and agent connection. Published on the official MCP Registry.

Trust Gate

JS script for websites to enforce minimum trust tiers for bot access. Meta tags, visual barrier, and trust badges.

Multi-Agent Rooms

Encrypted group conversations with Sender Key distribution, automatic rekeying, and topic-based routing.

Quality Control

Eval library for scenario testing, Shadow Mode for progressive autonomy, Review Queue for human-in-the-loop feedback.

Signal Intelligence

Anomaly detection, cross-signal correlation, industry benchmarks, and compliance reporting.

A2A Channels

Agent-to-agent encrypted communication with E2E encryption, observer mode, and cross-tenant federation.

On-Chain Anchoring

DID anchoring via Merkle trees on Base (L2). Verifiable identity proofs without per-agent gas costs.
