# `fastmcp.cli.run`
FastMCP run command implementation with enhanced type hints.
## Functions
### `is_url` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/cli/run.py#L28" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
```python
is_url(path: str) -> bool
```
Check if a string is a URL.
### `run_with_uv` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/cli/run.py#L34" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
```python
run_with_uv(server_spec: str, python_version: str | None = None, with_packages: list[str] | None = None, with_requirements: Path | None = None, project: Path | None = None, transport: TransportType | None = None, host: str | None = None, port: int | None = None, path: str | None = None, log_level: LogLevelType | None = None, show_banner: bool = True, editable: str | list[str] | None = None) -> None
```
Run a MCP server using uv run subprocess.
This function is called when we need to set up a Python environment with specific
dependencies before running the server. The config parsing and merging should already
be done by the caller.
**Args:**
- `server_spec`: Python file, object specification (file\:obj), config file, or URL
- `python_version`: Python version to use (e.g. "3.10")
- `with_packages`: Additional packages to install
- `with_requirements`: Requirements file to use
- `project`: Run the command within the given project directory
- `transport`: Transport protocol to use
- `host`: Host to bind to when using http transport
- `port`: Port to bind to when using http transport
- `path`: Path to bind to when using http transport
- `log_level`: Log level
- `show_banner`: Whether to show the server banner
- `editable`: Editable package paths
### `create_client_server` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/cli/run.py#L115" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
```python
create_client_server(url: str) -> Any
```
Create a FastMCP server from a client URL.
**Args:**
- `url`: The URL to connect to
**Returns:**
- A FastMCP server instance
### `create_mcp_config_server` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/cli/run.py#L135" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
```python
create_mcp_config_server(mcp_config_path: Path) -> FastMCP[None]
```
Create a FastMCP server from a MCPConfig.

```python
load_mcp_server_config(config_path: Path) -> MCPServerConfig
```
Load a FastMCP configuration from a fastmcp.json file.
**Args:**
- `config_path`: Path to fastmcp.json file
**Returns:**
- MCPServerConfig object
### `run_command` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/cli/run.py#L163" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```
Run a MCP server or connect to a remote one.
**Args:**
- `server_spec`: Python file, object specification (file\:obj), config file, or URL
- `transport`: Transport protocol to use
- `host`: Host to bind to when using http transport
- `port`: Port to bind to when using http transport
- `path`: Path to bind to when using http transport
- `log_level`: Log level
- `server_args`: Additional arguments to pass to the server
- `show_banner`: Whether to show the server banner
- `use_direct_import`: Whether to use direct import instead of subprocess
