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.
Click + Add Connection.
Give the connection a Name and (optionally) a Description.
Complete the authentication (OAuth sign-in, API key, etc.).
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:
Open Agents → Your Agent → MCPs.
Activate the MCP you just created.
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.
