# `fastmcp.server.middleware.response_limiting`
|
|
|
|
|
|
Response limiting middleware for controlling tool response sizes.
|
|
|
|
## Classes
|
|
|
|
### `ResponseLimitingMiddleware` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/server/middleware/response_limiting.py#L20" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

|
|
|
|
|
Middleware that limits the response size of tool calls.
|
|
|
|
Intercepts tool call responses and enforces size limits. If a response
|
|
exceeds the limit, it extracts text content, truncates it, and returns
|
|
a single TextContent block.
