# Missive

If you've ever wanted to create an MCP server for Missive to connect to it from Claude, ChatGPT, Cursor, or another tool, Relay.app makes that easy to do!&#x20;

If you'd just like to install a pre-built, simple version, use the template here: <https://run.relay.app/shared/missive-R8YI2CldzP4B>

If you'd like to build your own step-by-step, or run into any issues, follow the detailed steps here:

1. In the top left of the Relay.app home screen, click "Create new" and select MCP server.

2. Select your desired client and give your MCP server a name. I would recommend just calling it "Missive"

3. Next create custom tools for each of the actions you want, by clicking add Add tool and select Add custom tool. The two screenshots below show how to create a tool to find conversations in a team.

5. Once you have the tools you want, flip the MCP server on! Then follow the instructions to connect it to Claude or any other AI tool.
