## Introduction

Muse is Meta's AI assistant. It can connect to outside tools through custom connectors, which use the Model Context Protocol (MCP).
This guide explains how to connect Calendly to Muse using Composio Connect, which handles OAuth, token refresh, and reliability so you do not have to. You add Composio as a custom connector once, then ask Muse to work with Calendly in plain language.

## TL;DR

- Cross-app workflows across 1,500+ apps from a single plugin layer.
- On-demand tool loading so Muse only loads the tools needed for the current task.
- Programmatic tool calling through a remote workbench for complex, multi-step workflows.
- Multi-account support so users can connect and switch between multiple accounts for the same app.
- Shared account access so teams or agents can work through common business accounts and service connections.
- Managed authentication with OAuth handling, credential storage, and token refresh managed by Composio.
- Safer credential handling so app credentials stay outside the model context and tool responses.
- User-level account isolation so actions run against the correct connected account instead of mixing user access.

## Connect Calendly to Muse

### Connecting Calendly to Muse
You add Composio to Muse once as a custom connector, then connect Calendly from the chat.

## What is the Calendly MCP server, and what's possible with it?

The Calendly MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Calendly account. It provides structured and secure access to your scheduling, event types, availability, invitees, and organization, so your agent can manage event types, check availability, schedule invitees, review upcoming events, and cancel events on your behalf.
- Event type management: Have your agent list, create, and update one-on-one event types for different meeting needs.
- Availability control: Let the agent review or update the availability schedule for a specific event type.
- Meeting scheduling and cancellation: Direct your agent to add an invitee to an event or cancel a scheduled event when plans change.
- Schedule and submission review: Instruct your agent to list scheduled events or review submissions collected through a routing form.
- Team and account administration: Have your agent check connected account details, view organization information, invite users, or remove organization members.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CALENDLY_CANCEL_SCHEDULED_EVENT` | Cancel scheduled event | Tool to cancel a scheduled Calendly event by creating a cancellation record. Use when you need to permanently cancel an existing, active event. The cancellation will trigger notifications to all invitees. |
| `CALENDLY_CREATE_EVENT_TYPE` | Create Event Type | Tool to create a new one-on-one event type (kind: solo) in Calendly. Use when you need to programmatically create a new event type for scheduling meetings. |
| `CALENDLY_CREATE_ONE_OFF_EVENT_TYPE` | Create One-Off Event Type | Creates a temporary Calendly one-off event type for unique meetings outside regular availability, requiring valid host/co-host URIs, a future date/range for `date_setting`, and a positive `duration`. |
| `CALENDLY_CREATE_SCHEDULING_LINK` | Create scheduling link | Create a single-use scheduling link. Creates a scheduling link that can be used to book an event. The link allows invitees to schedule up to the specified maximum number of events. Once the limit is reached, the link becomes inactive. |
| `CALENDLY_CREATE_SHARE` | Create share | Creates a customizable, one-time share link for a Calendly event type, allowing specific overrides to its settings (e.g., duration, availability, location) without altering the original event type. |

| `CALENDLY_CREATE_WEBHOOKS` | Create webhook subscription | Tool to create a webhook subscription for receiving Calendly event notifications. Use when you need to set up automated notifications for events like meeting bookings or cancellations. Organization scope triggers webhooks for all events organization-wide, while user/group scopes limit triggering to specific users or groups. |

## Troubleshooting

### 1. Why doesn't Muse show a button to add my API key?

Muse shows the button only when you ask it to open the secure credentials store.
- Start a new chat.
- Send the message from step 1 exactly as written.
- If Muse asks for the key in the chat, do not paste it. Ask Muse to open the secure credentials store.

### 2. Why does the Composio connection fail after I add my API key?

The key or the connector settings are not correct.
- Copy the full key from the Composio dashboard. It starts with ck_.
- Make sure the URL is https://connect.composio.dev/mcp and the header is x-consumer-api-key.
- Remove the Composio connector in Muse settings, then do steps 1 to 3 again.

### 3. Why doesn't Muse use the Composio tools for Calendly?

Muse may not pick the Composio connector for the request.
- Ask Muse to list its Composio tools.
- Name Composio and Calendly in your request, for example: Use Composio to connect to Calendly.
- If it still does not work, start a new chat and try again.

### 4. Why does Muse ask me to connect Calendly again?

Your Calendly connection expired or was removed.
- Open the link Muse gives you and sign in to Calendly again.
- Check that the Calendly connection shows as ACTIVE in the Composio dashboard.

### 5. What do I do if I pasted my API key into the chat?

Treat the key as exposed.
- Create a new API key in the Composio dashboard and delete the old one.
- Add the new key in Muse's secure credentials store, not in the chat.

## Creating MCP Server - Stand-alone vs Composio SDK

Once connected, Muse can access the Calendly MCP server through Composio to run the actions you authorize, using plain language in the chat.

## Complete Code

None listed.

## Conclusion

### Way Forward
Now that Calendly is connected, extend your setup by connecting the other apps you already use every day, so Muse can run true cross-app workflows end to end.
- Connect Calendar to turn threads into scheduled meetings automatically.
- Connect Slack or Teams to post summaries, approvals, and alerts where your team works.
- Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs.
- Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps.
Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single connection, Muse can coordinate multiple tools safely and reliably in one conversation.

## Frequently Asked Questions

### Does Muse support MCP?

Yes. Muse supports custom connectors that use the Model Context Protocol (MCP). Composio connects as one custom connector over remote streamable HTTP at https://connect.composio.dev/mcp, and gives Muse access to Calendly and 1,500+ other apps.

### Where do I get the API key for the Composio connector?

Copy it from the Composio dashboard. It starts with ck_. Enter it only in Muse's secure credentials store, never in the chat.

### Can I connect more than one Calendly account to Muse?

Yes. Composio supports multiple connected accounts for the same app. Give each Calendly connection a name, such as work or personal, and tell Muse which one to use.

### How safe is my Calendly data with Composio?

Tokens, keys, and configuration are encrypted at rest and in transit. Your Composio API key stays in Muse's secure credentials store, not in the chat or the model context. Composio is SOC 2 Type 2 compliant.
