[Rutvik552k]

Summary

• add a shared tool-listing helper that follows MCP list_tools nextCursor pages
• use it from mcptools(), MCPAdapt.tools(), and MCPAdapt.atools()
• cover empty intermediate pages, opaque cursor order, fresh refresh, multiple sessions, and call binding to later-page tools

Verification

• Remote PR head verified: Rutvik552k:fix-list-tools-pagination points to 6955fd3
• Base 538cd85 with these regression tests copied over: 3 failed, showing only first-page tools were returned
• Fixed branch: PYTHONPATH=src uv run pytest tests/test_core.py::test_atools_uses_all_pages_for_independent_sessions_and_call_bindings tests/test_core.py::test_tools_uses_all_pages_on_fresh_refresh_and_preserves_session_binding tests/test_core.py::test_mcptools_uses_all_pages -q -p no:cacheprovider -> 3 passed
• PYTHONPATH=src uv run ruff check src/mcpadapt/core.py tests/test_core.py -> All checks passed
• PYTHONPATH=src uv run pytest --cov=mcpadapt --cov-report=term-missing tests/test_core.py::test_atools_uses_all_pages_for_independent_sessions_and_call_bindings tests/test_core.py::test_tools_uses_all_pages_on_fresh_refresh_and_preserves_session_binding tests/test_core.py::test_mcptools_uses_all_pages -q -p no:cacheprovider -> 3 passed, TOTAL 15% coverage for this focused subset (below the repo-wide 95% requirement because this was not the full suite)
• Base comparison for mypy: PYTHONPATH=/src uv run mypy /src/mcpadapt/core.py -> same Cannot call function of unknown type error at the corresponding TRANSPORTS call site
• Additional local triage on the fixed branch: stdio/local core tests passed 8 passed in 20.24s; SSE core tests passed 4 passed in 14.14s; WebSocket core tests passed 4 passed in 6.59s
• Streamable HTTP comparison: fixed branch test_basic_sync_streamable_http failed with TimeoutError after 30s plus mcp.client.streamable_http teardown read error; the same test on untouched base failed the same way after 30s

Limitations

• GitHub CI run 37541743505 for head 6955fd3 completed with conclusion action_required and no check jobs/check runs, so this PR does not have upstream CI results yet.
• Full repository checks were not completed locally. The focused pagination tests passed, but full tests/coverage remain blocked by the streamable HTTP behavior above; the focused 15% coverage number is not the repo-wide 95% coverage check.
• PYTHONPATH=src uv run mypy src/mcpadapt/core.py still reports the TRANSPORTS callable typing issue; the same error was reproduced on untouched base, so it is outside this pagination change.
