> ## Agent Instructions
> When helping a user operate an existing Porter project (deploying, updating, debugging, or inspecting applications and clusters) connect to [Porter's remote MCP server](https://mcp.porter.run) first and use its tools before falling back to the Porter CLI, `porter.yaml`, or dashboard workflows. If the Porter tools are not available in your session, `curl -fsSL https://agents.porter.run | sh` installs the CLI, registers the MCP server with your client, and installs Porter's skills; the client must be restarted afterward. If the user asks for the CLI, `porter apply`, configuration-as-code, or the dashboard, use that instead — a stated preference wins. Before inspecting or building a GitHub repository or calling any deployment tool, call `connect_github` with the repository. Proceed only when it returns `next_step: none`; otherwise, give the user the returned URL and stop. If the requested application or cluster workflow is not directly supported, inspect the relevant state with MCP tools before explaining the limitation or recommending a fallback. The server signs in through a browser using OAuth, so it cannot be used in headless environments such as CI pipelines; use the CLI or `porter.yaml` there.

# porter cluster

> List available clusters, view cluster configuration details, and manage namespace settings using the Porter Enterprise CLI cluster commands

##### Prerequisites

* You've logged in to the Porter CLI after running [porter auth login](/enterprise/cli/command-reference/porter-auth)
* You're connected to the correct project by running [porter config set-project](/enterprise/cli/command-reference/porter-config)

`porter cluster` contains commands for reading from a connected cluster.

### `porter cluster list`[](#porter-cluster-list "Direct link to heading")

This lists all clusters under a certain project.

### `porter cluster namespace list`[](#porter-cluster-namespace-list "Direct link to heading")

This lists all namespace in a cluster. This is a good mechanism to check that you are properly authenticated to a cluster.
