Implementation Reference
- The @server.call_tool() handler that executes the get-unified-diff tool by generating a unified diff between two input strings using difflib.unified_diff.
@server.call_tool() async def handle_call_tool( name: str, arguments: dict | None ) -> list[types.TextContent | types.ImageContent | types.EmbeddedResource]: """ Handle tool execution requests. Tools can modify server state and notify clients of changes. """ if name != "get-unified-diff": raise ValueError(f"Unknown tool: {name}") if not arguments: raise ValueError("Missing arguments") string_a: str = arguments.get("string_a") string_b: str = arguments.get("string_b") if string_a is None or string_b is None: raise ValueError("Missing 'string_a' or 'string_b' in arguments") diff_iterator = difflib.unified_diff(string_a.splitlines(), string_b.splitlines()) return [types.TextContent(type="text", text="\n".join(diff_iterator))] - JSON schema defining the required input parameters 'string_a' and 'string_b' for the get-unified-diff tool.
