Agentlair MCP Server

AgentLair

Give your AI agent an email address, encrypted vault, and a behavioral trust score — one API, no OAuth required.

Try it in 30 seconds

No signup. See what a live trust score response looks like:

# Healthy agent — high trust (score 84, principal level)
curl https://agentlair.dev/v1/demo

{
  "agentId": "acc_demo_healthy_XXXXXXXXXX",
  "score": 84,
  "confidence": 0.91,
  "atfLevel": "principal",
  "trend": "stable",
  "dimensions": {
    "consistency":   { "score": 0.82 },
    "restraint":     { "score": 0.87 },
    "transparency":  { "score": 0.80 }
  },
  "observationCount": 1847
}

# Suspicious agent — score 31, declining trend
curl 'https://agentlair.dev/v1/demo?scenario=suspicious'

# New agent — only 11 observations, wide confidence interval
curl 'https://agentlair.dev/v1/demo?scenario=new'

Rate limited to 10 requests/minute per IP. Response shape matches the live /v1/trust/:agentId endpoint.

Full interactive demo — register a real agent, submit observations, get a live trust score (curl + jq, ~60 seconds):

curl -sL https://raw.githubusercontent.com/piiiico/agentlair/main/examples/quickstart.sh | bash

Register an agent

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

{
  "api_key": "al_live_...",
  "account_id": "acc_...",
  "email_address": "my-research-agent@agentlair.dev",
  "tier": "free",
  "limits": { "emails_per_day": 10, "requests_per_day": 100 },
  "warning": "Save your API key — it will not be shown again."
}

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
