+Custom agents beyond the ones listed in the [Coder registry](https://registry.coder.com/modules?tag=agent) can be used with Coder.
+
+## Prerequisites
+
+- A Coder deployment with v2.21 or later
+- A [Coder workspace / template](./create-template.md)
+- A custom agent that supports Model Context Protocol (MCP)
+
+## Getting Started
+
+Coder uses the [MCP protocol](https://modelcontextprotocol.io/introduction) to report activity back to the Coder control plane. From there, activity is displayed in the Coder dashboard.
+
+First, your template will need a [coder_app](https://registry.terraform.io/providers/coder/coder/latest/docs/resources/app) for the agent. This can be a web app or command run in the terminal and ideally gives the user a UI to interact with or view more details about the agent.
+
+From there, the agent can run the MCP server with the `coder exp mcp server` command. You will need to set the `CODER_MCP_APP_STATUS_SLUG` environment variable to match the slug in the coder_app resource.
+
+## Example
+
+Inside a Coder workspace, run the following commands:
+
+```sh
+coder login # be sure to be authenticated with the Coder CLI
+export CODER_MCP_APP_STATUS_SLUG=my-agent # needs to be the same as the slug in the coder_app resource
+
+# Use your own agent's logic and syntax here:
+any-custom-agent configure-mcp --name "coder" --command "coder exp mcp server"
+```
+
+This will start the MCP server and report activity back to the Coder control plane on behalf of the coder_app resource.
+
+> See the [Goose module](https://github.com/coder/modules/blob/main/goose/main.tf) source code for a real world example.
+
+## Contributing

+We welcome contributions for various agents via the [Coder registry](https://registry.coder.com/modules?tag=agent)!
