Member Function Documentation

execute()

ServerResponse entropic::WriteFileTool::execute ( const std::string &  args_json )

overridevirtual

Write content to a file after read-before-write check.

Execute write_file: resolve, enforce policy, write.

Parameters

args_json

JSON with "path" and "content" keys.

Returns

ServerResponse with result or error. @dg_internal

Version

1.8.5

The path is resolved against the root first (so a traversal attempt never reaches the write), then the read-before-write gate runs.

Parameters

args_json

JSON with "path" and "content" keys.

Returns

A ServerResponse with no directives whose result is either a success JSON naming the path and bytes written, or the structured read_before_write error — in which case nothing is written. @req REQ-MCP-021

Version

1.8.5

Implements entropic::ToolBase.
