The calendar built
for AI agents

Give your agents their own API keys with per-calendar, per-action access controls. No OAuth screens. No human in the loop.

Works with Claude Code, Clawdbot, any HTTP agent

I want to connect my calendar via Limehouse API, check out the docs here: https://cal.limehouse.io/skill.md
Fetched and reviewed Calendar API documentation

I found the Limehouse Calendar API docs. Here's what you need to know to connect:

Authentication

All requests use: Authorization: Bearer cal_<api-key>

Available endpoints:

  • GET /agent/meagent info & permitted calendars
  • GET /agent/calendarslist accessible calendars
  • GET /agent/calendars/{id}/eventslist events (with optional date filtering)
  • POST /agent/calendars/{id}/eventscreate events
  • PUT /agent/calendars/{id}/events/{event_id}update events
  • DELETE /agent/calendars/{id}/events/{event_id}delete events

To get started, I'll need your API key — do you have a cal_... key from Limehouse?

Verified agent authentication and retrieved agent configuration

Connected! Here's your agent info:

Agent: My Scheduling Bot

Connected calendar: alex@example.com

Permissions (read-only):

  • Read: yes
  • Create / Update / Delete: no

You only have read access to this calendar. What would you like to do — browse upcoming events, look at a specific date range, or something else?

What do I have next on my calendar?

Your next event today is:

Team Standup — 2:00–2:30 PM today

A recurring sync with the engineering team. Dial-in link is in the event description.

After that you have Product Review at 4:00–5:00 PM.

Agent-first, from the ground up

Every calendar API was built for humans clicking through OAuth flows. Limehouse is built for agents that need clean, scoped, programmatic access.

Agent API keys

Each agent gets its own API key (cal_...). No shared credentials, no OAuth tokens to refresh. Issue, rotate, or revoke any time.

Granular permissions

Control exactly what each agent can do — per calendar. Grant read access to one, full write access to another, and nothing else.

Agent-owned calendars

Agents can create and fully own calendars. Let your agent manage its own schedule — meetings, tasks, availability — without borrowing anyone else's.

User calendar access

Let users share their Google, Outlook, or iCal calendars with your agent. Your agent can read their availability and schedule around it.

Clean REST API

List events, create events, update, delete — all through simple, predictable HTTP endpoints. Designed to be called by code, not clicked through a UI.

Multi-agent ready

One account, unlimited agents. Give each agent exactly the calendars and permissions it needs — nothing more.

Set up in minutes

Your agent generates a setup link, you authorize access, and it's ready to go.

01

Create an agent

Ask your AI agent to connect your calendar. It generates a setup link for you. Click it, sign in with Google or Microsoft, and pick your calendars.

02

Grant calendar access

Pick which calendars the agent can see, and exactly what it can do: read events, create, update, delete, or invite attendees.

03

Use the calendar

Your agent can use the calendar via MCP, Claude, or the REST API directly. No session management, no token refresh, no OAuth dance.

Permissions that actually make sense

Don't give your scheduling agent the ability to delete events. Don't let your read-only reporting agent create anything. Set exactly what each agent needs, per calendar.

  • Discrete permission flags per calendar
  • Different permissions on different calendars
  • Update permissions any time from the dashboard
  • API enforces permissions on every request

Enforced on every request

Permissions aren't just advisory — the API rejects any action the agent isn't allowed to take. Your agent knows exactly what it can and can't do, and tells the user why.

Can you move the book club event to the community center?

Unfortunately I'm not able to do that — the API key you've connected only has read permissions on this calendar. The can_update permission is set to false, so any update request would be rejected.

To fix this, you'd need to update the agent's permissions in Limehouse with update enabled. Once you do, I can make that change for you.

Ok just delete the book club event then

Same issue — can_delete is also set to false, so I can't delete events either.

You'll need to enable delete (and/or update) in the agent's calendar permissions in Limehouse before I can make any changes.

Frequently asked questions

You can — but with AgentKeychain, you control which sites your agent signs up for and what information is shared. You can also set the agent's email if you want it to receive messages from the site. And because sites know your agent is tied to a real person, they can offer a captcha-free signup experience instead of treating it like a bot.

AgentKeychain needs to verify that you're a real person with a real account so it can attest that your agent is backed by a human. That's why there's no option to sign up with just email and password — it's the foundation of the trust model.

You can revoke access with one click from the dashboard. Once revoked, the agent's credentials are invalidated within minutes.

Every signup and authentication event is recorded in your audit log. You can see exactly which sites your agent has accessed, when, and what actions were taken.

AgentKeychain is for agents, not humans. If we let people sign into AgentKeychain with AgentKeychain, bots could create accounts — which defeats the entire purpose. You prove you're human just once to AgentKeychain, and then AgentKeychain can attest for you across every site your agent visits.

They can, but they provide significantly stronger identity signals than email and password alone. Google and Microsoft accounts carry years of account history, device trust, and behavioral signals that make them much harder to fake at scale.

AgentKeychain stores your account identity (Google or Microsoft) and a record of which agents you've authorized and which sites they've accessed. We never store your personal passwords — your Google or Microsoft login is handled entirely through OAuth. Agent credentials for third-party sites are generated per-site and can be revoked independently.

Because each site gets its own agent credential, a breach at one site doesn't affect any others. You can revoke the compromised credential from your dashboard and your agent can re-register with a fresh one.

AgentKeychain is free for individual use. We'll share more about plans for teams and higher-volume usage soon.
