```

--------------------------------

### Install a capability

Source: https://docs.dreadnode.io/cli/capability

Installs a capability, making it available for agents to use. Can install from a local path or a registry reference.

```APIDOC
## install

### Description
Install a capability so agents can use it.
If the argument is a path to a directory on disk, the capability is validated and symlinked into ~/.dreadnode/capabilities/ so edits are live. Use —copy to create a frozen snapshot instead.
Otherwise the argument is treated as a registry reference and the capability is downloaded from the platform.

### Options

* `<ref>`, `--ref` _(**Required**)_ — Capability reference or local path. Registry: my-cap, my-cap@1.0.0, acme/my-cap. Local: ./my-cap, /abs/path/to/cap.
* `--force` _(default`False`)_ — Overwrite if already installed.
* `--copy` _(default`False`)_ — Copy files instead of symlinking (local installs only).
```

--------------------------------

### Initialize a new capability

--------------------------------

### MCPClient Initialization and Usage

Source: https://docs.dreadnode.io/sdk/agents

Demonstrates how to initialize and use the MCPClient, either as an async context manager or with explicit connect/disconnect calls.

```APIDOC
## MCPClient

A client for communicating with MCP servers. Supports stdio and streamable-http transports. For streamable-http, SSE is used as an automatic fallback if the server doesn’t support the streamable HTTP protocol.

Can be used as an async context manager or via explicit connect/disconnect:

### Context manager (existing pattern)
```python
async with mcp("stdio", command="uv", args=["run", "server"]) as client:
    agent = Agent(tools=list(client.tools))
```

### Explicit lifecycle (for managed servers)
```python
client = MCPClient.from_config(StdioServerConfig(command="uv"))
await client.connect()
try:
    ...
finally:
    await client.disconnect()
```

### `connect()`
Connect to the MCP server and discover tools. Sets status to CONNECTED on success, FAILED or NEEDS_AUTH on error.

### `disconnect()`
Disconnect from the MCP server.

### `from_config()`
Create a client from a typed server config. The SDK’s MCP lifecycle manager passes `log_path` to tee stderr under `~/.dreadnode/logs/`. User-code callers of :func:`dreadnode.agents.mcp` don’t need to supply it.
```

--------------------------------

### Referencing Tasks CLI Examples

Source: https://docs.dreadnode.io/evaluations/tasks

Demonstrates how to reference tasks using the `dn` CLI for inspection, environment provisioning, and evaluation creation.

```bash
# Inspect a task
