12731273* **Default limit**: the default maximum is 25,000 tokens
12741274* **Scope**: the environment variable applies to tools that don't declare their own limit. Tools that set [`anthropic/maxResultSizeChars`](#raise-the-limit-for-a-specific-tool) use that value instead for text content, regardless of what `MAX_MCP_OUTPUT_TOKENS` is set to. Tools that return image data are still subject to `MAX_MCP_OUTPUT_TOKENS`
12751275* **Over the limit**: when a successful result with no image content exceeds the token limit, Claude Code saves it to a file and replaces it in the conversation with a message that names the file path, so Claude reads the file when it needs the content. The file goes in the session's `tool-results` directory under [`~/.claude/projects/`](/docs/en/claude-directory#cleaned-up-automatically).
1276* **Response size from HTTP and SSE servers**: Claude Code stops reading a response from an [HTTP](#option-1-add-a-remote-http-server) or [SSE](#option-2-add-a-remote-sse-server) server once one JSON response body, or one event of an event stream, passes 16 MB after decompression. The request that response answers fails. If you maintain the server, return less data per response to stay under the limit, for example by paginating results
