# How to Connect a New MCP

This guide shows, step-by-step, how to add a Managed Connection Provider (MCP) and make its tools available to your Agents and Workflows.

***

### Step-by-step

#### 1) Open the MCPs area

Go to **MCPs** in the left navigation and click **New MCP**.

#### 2) Choose the integration

Select the MCP you want (e.g., **Google Calendar**, **Notion**, **Airtable**, **Slack**, etc.).

#### 3) Name and describe

Fill in:

* **MCP Name** – a clear internal name (e.g., “Google Calendar – Sales”).
* **Description** (optional) – what this integration is for (helps future you and teammates).

#### 4) Create a Connection (authentication)

Connections are the authentication layer shared by all tools inside the MCP.

1. Click **+ Add Connection**.
2. Give the connection a **Name** and (optionally) a **Description**.
3. Complete the authentication (OAuth sign-in, API key, etc.).
4. Once successful, the connection will appear in the list.

> Pro tip: use different connections for different teams or accounts, so permissions remain separated.

#### 5) Enable the tools you need

All tools start **disabled**. Click to **activate** only the ones your Agent should use.\
Hovering over a tool shows what it does (e.g., in Google Calendar: *create event*, *find free slots*, *update event*).

#### 6) Create the MCP

Click **Create MCP**. Your integration is now available in Endless.

### Make MCP tools available to an Agent

Unlike custom tools or tables, you don’t have to add each tool individually.\
Instead:

1. Open **Agents → Your Agent → MCPs**.
2. Activate the MCP you just created.
3. Done ✅ — all selected tools inside that MCP are now automatically available for the Agent.

***

### Test internally (recommended)

Use the **internal chat** on the Agent’s page:

* Example for Google Calendar MCP:
  * “Find me 3 free 30-minute slots this week.”
  * “Book a meeting with John tomorrow at 10am.”

The Agent will gather missing details (date, participants, duration) and then trigger the right tool.

***

### Troubleshooting

* **MCP created but no tools available?**\
  Make sure you enabled at least one tool before saving.
* **Auth completed but calls fail?**\
  Verify the connection’s

👉 With this, you now know how to create an MCP, connect it, activate its tools, and make them instantly available for your Agent.
