The MCP Writer is a key component of FME's MCP (Model Context Protocol) integration.
The writer is used to define a tool response that will be returned when the workspace is run as an MCP tool in FME Flow. This will allow users to take any data processed in an FME workspace and shape it into an MCP tool response that an MCP client (for example, AI agents) can consume directly.

Writer Overview
When a workspace containing the MCP Writer is run, the writer accumulates all features routed to it and serializes them into a JSON-RPC 2.0 formatted response document.
The resulting JSON document will then be used by FME Flow to return an MCP Response. The output file conforms to the tool response format and requirements defined in the MCP Tools Specification.
