There are two ways to set this up: - Via [Composio Connect MCP](https://dashboard.composio.dev/) - Via the [Composio CLI](https://dashboard.composio.dev/) ## Also integrate Calendly with - [ChatGPT](https://composio.dev/toolkits/calendly/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/calendly/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/calendly/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/calendly/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/calendly/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/calendly/framework/codex) - [Cursor](https://composio.dev/toolkits/calendly/framework/cursor) - [VS Code](https://composio.dev/toolkits/calendly/framework/vscode) - [OpenClaw](https://composio.dev/toolkits/calendly/framework/openclaw) - [Hermes](https://composio.dev/toolkits/calendly/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/calendly/framework/cli) - [Google ADK](https://composio.dev/toolkits/calendly/framework/google-adk) - [LangChain](https://composio.dev/toolkits/calendly/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/calendly/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/calendly/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/calendly/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/calendly/framework/crew-ai) ## TL;DR ### Why use Composio? Composio provides a single MCP server or CLI tool that exposes a set of meta-tools, allowing you to: - Connect to 1,000+ apps with on-demand tool loading, so you do not fill your LLM context window with unnecessary tool definitions. - Use programmatic tool calling through a remote Bash tool, letting LLMs write their own code to handle complex tool chaining. This reduces back-and-forth for frequent tool calls. - Handle large tool responses outside the LLM context to keep conversations lean. ## Connect Calendly to OpenCode ### Connect Calendly with OpenCode ### Option 1: Using Composio CLI ### 1. Install Composio CLI Install the Composio CLI, authenticate, and initialize your project: ```bash # Install the Composio CLI curl -fsSL https://composio.dev/install | bash # Authenticate with Composio composio login ``` ## 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 workflows, so your agent can perform actions like creating personalized scheduling links, managing events, handling invitee statuses, and automating reminders on your behalf. - Instant scheduling link creation: Direct your agent to generate single-use or shareable scheduling links so others can book time with you instantly—no more back-and-forth emails. - Automated event and invitee management: Have your agent cancel events, mark invitees as no-shows, or remove no-show statuses to keep your calendar accurate and up to date. - Custom one-off event setup: Empower your agent to create unique, one-off meeting types for special situations, bypassing your regular availability rules. - Webhook subscription automation: Let the agent set up webhook subscriptions to trigger notifications or workflows in real time when events happen in your Calendly account. - Data privacy and compliance actions: Instruct your agent to delete invitee data or scheduled event records as needed for privacy or regulatory compliance, especially for enterprise use cases. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CALENDLY_CANCEL_EVENT` | Cancel event | Permanently cancels an existing, active scheduled event by its `uuid`, optionally providing a `reason`, which may trigger notifications to invitees. | | `CALENDLY_CREATE_INVITEE_NO_SHOW` | Create an invitee no-show | Marks an invitee, identified by their existing and valid uri, as a 'no show' for a scheduled event. | | `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_SINGLE_USE_SCHEDULING_LINK` | Create single use scheduling link | Creates a one-time, single-use scheduling link for an active calendly event type, expiring after one booking. | | `CALENDLY_CREATE_WEBHOOK_SUBSCRIPTION` | Create webhook subscription | Creates a calendly webhook subscription to notify a specified `url` (which must be a publicly accessible https endpoint) for selected `events` within a given `organization` and `scope`. | | `CALENDLY_DELETE_INVITEE_DATA` | Delete invitee data | Permanently removes all invitee data associated with the provided emails from past organization events, for data privacy compliance (requires enterprise subscription;

Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single MCP endpoint, your agent can coordinate multiple tools safely and reliably in one conversation. ## How to build Calendly MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/calendly/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/calendly/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/calendly/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/calendly/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/calendly/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/calendly/framework/codex) - [Cursor](https://composio.dev/toolkits/calendly/framework/cursor) - [VS Code](https://composio.dev/toolkits/calendly/framework/vscode) - [OpenClaw](https://composio.dev/toolkits/calendly/framework/openclaw) - [Hermes](https://composio.dev/toolkits/calendly/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/calendly/framework/cli) - [Google ADK](https://composio.dev/toolkits/calendly/framework/google-adk) - [LangChain](https://composio.dev/toolkits/calendly/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/calendly/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/calendly/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/calendly/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/calendly/framework/crew-ai) ## Related Toolkits - [Google Calendar](https://composio.dev/toolkits/googlecalendar) - Google Calendar is a time management service for scheduling meetings, events, and reminders.

With a standalone Calendly MCP server, the agents and LLMs can only access a fixed set of Calendly tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Calendly and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with OpenCode? Yes, you can. OpenCode fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Calendly tools. ### Can I manage the permissions and scopes for Calendly while using Tool Router? Yes, absolutely. You can configure which Calendly scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Calendly data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
