Initial Checks

Description

The enable_tasks() method doesn't properly set the tasks.requests.tools.call capability on the server, causing compatibility issues with clients that assert against server capabilities before attempting task support on a tool invocation.

Identified during strands-agents/harness-sdk#1475.

Example Code



Python & MCP Python SDK


Python 3.12.9
MCP SDK 1.25.0
