What is Double's MCP server?
Double's MCP (Model Context Protocol) gives your AI agents tools to read and make updates to your account. This lets you manage your clients, teammates, and tasks through an AI assistant without switching apps.
For example, you could ask your AI assistant:
My teammate Melissa will be out of office next week, can you reassign their tasks to Jillian?
Here's a transcript of an onboarding meeting I had with a client - please create some action items as tasks in the General task section. I want these to be due at the end of the week and assigned to Ryan.
I'd like to know how my team's performing. Which users are completing the most work, and which are routinely completing their tasks late? Could you provide me with a score for each of them?
I need some calendar reminders - can you create tasks in my google calendar for all of the Double tasks that are due today and assigned to me?
Connecting your agents with Double
Double's MCP currently supports custom connections with Claude and ChatGPT.
Claude
In the Claude desktop app, open the sidebar menu
Navigate to Customize → Connectors
Click the + button then Add custom connector:
Name = Double
Remote MCP server URL = https://api.doublehq.com/mcp
You can also configure permissions to control what your agent is allowed to perform inside of your Double account. We recommend setting read-only tools to Always allow by default, but setting permissions for write tools more granularly as you get used to working with the MCP.
