AgentLair tools (15, 5 write)

write = sends, deletes, buys or posts
  • calendar_create_eventwrite actionFree

    Create a calendar event on your AgentLair calendar. Events are published via iCal feed for human subscription (Google Calendar, Apple Calendar, Outlook).

  • calendar_delete_eventwrite actionFree

    Delete an event from your AgentLair calendar by event ID. Use calendar_list_events to find event IDs.

  • calendar_get_feedFree

    Get the public iCal subscription URL for your AgentLair calendar. Share this URL with calendar apps (Google Calendar, Apple Calendar, Outlook) so humans can subscribe and see agent-created events.

  • calendar_list_eventsFree

    List events on your AgentLair calendar. Optionally filter by date range.

  • check_inboxFree

    Check the inbox for an @agentlair.dev email address. Returns recent messages with sender, subject, and received time.

  • claim_addressFree

    Claim a new @agentlair.dev email address for your agent. Free tier supports multiple addresses.

  • delegate_taskFree

    Delegate a task to another AgentLair agent. The task is delivered to the agent's inbox and picked up asynchronously. Use this when you need another agent to do something — send an email, run a deployment, do research, etc.

  • list_addressesFree

    List all @agentlair.dev email addresses associated with your API key.

  • preflight_trust_checkFree

    Check trust readiness before engaging with an agent. Returns a ReadinessCard: trust score, behavioral maturity level, whether it's safe to engage, and any caveats. Call this before delegating tasks, accepting agent output, or authorizing payments involving an unknown agent. Free — no extra charge beyond your API key.

  • read_messageFree

    Read the full content of a specific email message, including the body text.

  • send_emailwrite actionFree

    Send an email from your AgentLair address (@agentlair.dev) to any recipient. No SMTP or DNS setup needed.

  • vault_deletewrite actionFree

    Delete a key and all its versions from the AgentLair Vault.

  • vault_getFree

    Retrieve a stored value from the AgentLair Vault by key name.

  • vault_listFree

    List all keys stored in your AgentLair Vault (metadata only, values not returned).

  • vault_putwrite actionFree

    Store a value in the AgentLair Vault. Use this to persist API keys, secrets, or any data your agent needs across sessions. Best practice: encrypt sensitive data client-side before storing (the server stores whatever you send).

What the publisher says

From the AgentLair repository's README, as published. We do not edit it. Read it on GitHub

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.

Quickstart: Add AgentLair to your agent

1. Install

pip install agentlair            # Python
npm install @agentlair/sdk       # TypeScript / Node

2. Set env vars

export AGENTLAIR_API_KEY=al_live_...
export AGENTLAIR_EMAIL=my-agent@agentlair.dev

3. Wire lifecycle hooks

# Python — three integration points
import os, agentlair
lair = agentlair.AgentLair(os.environ["AGENTLAIR_API_KEY"])
addr = os.environ["AGENTLAIR_EMAIL"]

async def on_session_start(ctx):
    result = await lair.email.inbox(addr)
    if result["messages"]:
        ctx.prepend(f"Inbox: {len(result['messages'])} unread")

async def send_message(to, subject, text):  # expose as LLM tool
    await lair.email.send(from_address=addr, to=to, subject=subject, text=text)

async def on_session_end(ctx):  # advance cursor so messages aren't re-delivered
    if ctx.last_message_id:
        await lair.vault.store("inbox_cursor", ctx.last_message_id)
// TypeScript
import { AgentLair } from '@agentlair/sdk';
const lair = new AgentLair(process.env.AGENTLAIR_API_KEY!);
const addr = process.env.AGENTLAIR_EMAIL!;
