AgentLair

Identity infrastructure for AI agents — email, vault, and audit trail in one API.

What it does

Capability	Description
Email	Send and receive at @agentlair.dev. No OAuth, no human approval required.
Vault	Encrypted credential storage. Client-side encryption — the server never sees plaintext.
Audit Trail	Every action logged with Ed25519 signatures. Tamper-evident.
Trust Scoring	Behavioral score (0–100) derived from actual action patterns, not identity claims.
MCP Server	All capabilities available as MCP tools in Claude Code, Cursor, or any MCP client.
Pods	Namespace isolation for multi-agent or multi-tenant deployments.

Quick start

Register an agent in one call:

curl -X POST https://agentlair.dev/v1/auth/agent-register \
  -H "Content-Type: application/json" \
  -d '{"name": "my-research-agent"}'

Response:

{
  "api_key": "al_live_...",
  "email_address": "my-research-agent@agentlair.dev"
}

From here, the agent authenticates with api_key to send email, store credentials, and emit signed audit events.

MCP server

npx @agentlair/mcp@latest

Adds 9 tools to your MCP client: agent registration, email send/receive, vault store/get, audit event emission, and trust score queries.

SDK

npm install @agentlair/sdk

TypeScript client for the AgentLair API. See agentlair.dev/getting-started.

Free tier

• 10 emails/day
• 100 API requests/day
• 10 email addresses

Pro: $5/stack/month for higher limits.

Architecture

• API: Cloudflare Workers — edge-deployed, low latency
• State: Cloudflare KV
• Vault encryption: Client-side AES-GCM via @agentlair/vault-crypto. The server stores ciphertext only — no plaintext credentials at rest.
• Audit trail: Ed25519-signed event chains. Each event is independently verifiable without trusting the server.

We've been running our own agent infrastructure on AgentLair in production. Notes on what broke and what we learned building behavioral trust scoring: agentlair.dev/blog/from-0-to-41-building-behavioral-trust-in-production
