# `fastmcp.server.transforms.resources_as_tools`
Transform that exposes resources as tools.
This transform generates tools for listing and reading resources, enabling
clients that only support tools to access resource functionality.
The generated tools route through `ctx.fastmcp` at runtime, so all server
middleware (auth, visibility, rate limiting, etc.) applies to resource
operations exactly as it would for direct `resources/read` calls.
Example:
```python
from fastmcp import FastMCP
from fastmcp.server.transforms import ResourcesAsTools
mcp = FastMCP("Server")
mcp.add_transform(ResourcesAsTools(mcp))
# Now has list_resources and read_resource tools
```
## Classes
### `ResourcesAsTools`
Transform that adds tools for listing and reading resources.
Generates two tools:
- `list_resources`: Lists all resources and templates
- `read_resource`: Reads a resource by URI
The generated tools route through the server at runtime, so auth,
middleware, and visibility apply automatically.
This transform should be applied to a FastMCP server instance, not
a raw Provider, because the generated tools need the server's
middleware chain for auth and visibility filtering.
**Methods:**
#### `list_tools`
```python
list_tools(self, tools: Sequence[Tool]) -> Sequence[Tool]
```
Add resource tools to the tool list.
#### `get_tool`
```python
get_tool(self, name: str, call_next: GetToolNext) -> Tool | None
```
Get a tool by name, including generated resource tools.
