Summary

Treat integer second counts (including the default 5) as valid client_session_timeout_seconds values when constructing MCP ClientSession timeouts.

Motivation

Fixes #91. The default timeout is the integer 5, but mcptools only converted float and timedelta values. With the default argument, timeout stayed None, so the documented 5-second session timeout was never applied.

Changes

• Accept int and float second counts (excluding bool) when building the timedelta passed to ClientSession.
• Extend type hints on mcptools and MCPAdapt.__init__.
• Add a mocked regression test covering explicit 5 and the default path.

Tests

• python3 -m pytest tests/test_core.py::test_mcptools_converts_int_client_session_timeout tests/test_core.py::test_client_session_timeout_parameter_propagation -q → 2 passed

Notes

Minimal behavior change; existing float, timedelta, and None handling is unchanged.
