# `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` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/transforms/resources_as_tools.py#L41" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>


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` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/transforms/resources_as_tools.py#L78" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
list_tools(self, tools: Sequence[Tool]) -> Sequence[Tool]
```

Add resource tools to the tool list.


#### `get_tool` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/transforms/resources_as_tools.py#L86" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
get_tool(self, name: str, call_next: GetToolNext) -> Tool | None
```

Get a tool by name, including generated resource tools.
